INTRODUCTION I The Indian River County Department of Utility Services authorized Kimball•Lloyd, Inc. to perform an engineering study to evaluate the construction of a sanitary sewer collection system in the Indian River Drive area of Sebastian, Florida. The County plans to eliminate the existing septic tanks and smaller (package) sewage treatment plants in order to improve the water quality of the Indian River. The smaller sewage treatment plants discharge their wastewater effluent into the Indian River either directly, through outfall pipes, or indirectly, by irrigation spraying which filters through the soils into the water table. Individual septic tanks discharge their treated wastewater (i.e., leachate) by leaching from their drainfields through the soil down to the water table where the leachate is eventually conveyed to the Indian River via groundwater movement. By constructing a sewer collection system, the County hopes to eliminate the discharge of wastewater to the river, which would help meet the goals of both the State's SWIM Plan and the County's Comprehensive Plan which call for the elimination of wastewater discharges to the Indian River. The Indian River in the area of Sebastian has been designated as an Outstanding Florida Water. The study area for the sewer collection system is bounded on the west by U.S. 1, on the north ! and south by the intersection of U.S. I and Indian River Drive, and on the east by the Indian L River. This area is composed of single- and multi -family residential, commercial, mobile home, Land park areas. It should be noted that within the study area, the County has previously installed I gravity sewer lines and a master lift station at the north end of Indian River Drive. Also, a force main extends from the master lift station south along Indian River Drive to the point where Indian River Drive intersects U.S. 1. The purpose of this study is to develop a cost-effective sewer collection system for the identified area. Two general types of sewer collection systems will be evaluated: gravity sewers and low pressure sewers. A recommendation as to which type of system or systems to construct for the various service areas will be based on such things as construction cost, operation and maintenance cost, and ease of construction. After a recommendation has been made and accepted, construction drawings and specifications will be produced in accordance with the t recommended alternative. H. BACKGROUND INFORMATION Sewer systems are essential to the public health and welfare in areas of concentrated population and development. Every community produces wastewater of domestic, commercial, or industrial origin. Sewers perform the vital functions of collecting the wastewaters and conveying them to points of treatment and disposal, in this case, a wastewater treatment plant. i The importance of a sewer system is frequently overlooked by the community, as a properly functioning sewer system is virtually invisible. However, when a septic tank overflows, a drainfield line becomes clogged, or the wastewater becomes a pollutant, the necessity for a Iproperly functioning sewer system becomes very visible. 2 This study analyzes the possibility of using gravity sewer collection systems or low pressure sewer systems. Each alternative has its inherent advantages, disadvantages, and typical application conditions. A discussion of gravity and low pressure sewer systems is presented in the following. IA. GRAVITY SEWER SYSTEMS 1,General: The gravity sewer is the most basic form of sewer collection. As the name indicates, a "gravity sewer" uses the force of gravity to move wastewater down a sewer pipe which is laid on a very slight downward slope. The slopes may vary depending upon the diameter of the pipe selected with the general rule that as the pipe diameter decreases, the slope must increase. Minimum pipe size recommended for gravity sewers is eight -inch diameter (except service laterals which are four- or six-inch diameter). Most municipal standards recommend that typical eight -inch pipes be installed with a slope of 0.4%, which means that the pipe drops 0.4 feet for every 100 feet of pipe length. An eight -inch gravity sewer laid at 0.4% slope is capable of conveying approximately 350 gallons of sewage per minute. Slopes of less than 0.33% are not recommended because velocities Lin the pipe will fall below the necessary 2.0 feet per second required to keep solids moving along the pipe. Gravity sewer systems are typically constructed in La roadway. The basic components of a gravity sewer system are sewer pipe, manholes, service laterals, lift stations, and force mains (see Exhibit II -1).

I 9 93 M Gravity Sewer Pipe: The most common pipe materials utilized for gravity sewers are polyvinyl chloride (PVC) and ductile iron. PVC pipe is, at present, less expensive than ductile iron and is more resistant to the corrosive fluids and gases present in a sewer system. However, in certain cases, ductile iron is the preferred pipe due to its material strength. In most cases where the sewer collection system is relatively small and the volume of wastewater is not great, as in the study area, the standard pipe diameter for a gravity sewer is eight inches. The greater the volume of sewage to be conveyed, the larger the required pipe diameter and/or the steeper the pipe slope required. Manholes: The next component of a gravity sewer system is the manhole. A manhole is a concrete cone that extends from the belowground elevation of the sewer pipe up to the surface of the ground. Access to the manhole is provided by means of a steel cover. A sewer pipe connects to the manhole through holes in the manhole's sides. The manholes serve as a place where maintenance personnel can enter and inspect, clean, and maintain the sewer pipe. Manholes are normally located at changes in direction, grade, or pipe size, or at intersections of collecting sewers. Manholes should be spaced no further apart than 400 feet to permit inspection and cleaning when necessary. In areas of potential flooding, watertight manhole covers should be utilized to minimize the inflow of stormwater into the sewer system. Service Laterals: The gravity sewer line that connects a house or building to the main sewer line is called the "service lateral", because the service pipe is installed 4 laterally from the main line. Service laterals are usually six inches in diameter because they carry the low volume of wastewater flow from only one, or a few, buildings. They are laid at grades ranging from 1 % to 2 %. Most service laterals are installed from the main sewer line up to the property line where the building owner connects his individual sewer service to the service lateral (see Exhibit 1 H-2). 1 5. Pumping Stations or Lift Stations: It is often necessary to accumulate wastewater at a low point in the collection system and pump it to treatment works or to a continuation of the system at a higher elevation. Pumping stations consist primarily of a wetwell, which intercepts incoming flows and permits equalization of pump loadings, and a bank of pumps, which lift the wastewater from the wetwell. This collection point is called a "lift station" or "pump station" because the wastewater is pumped upwards toward the surface where it is discharged into a pressurized pipeline called a "force main." Force mains are pressurized pipelines that push (force) the wastewater over long distances to its final destination, which is usually a wastewater treatment plant. Pump stations are v i required in various areas of the collection system in order to avoid excessive depths of cut for the gravity sewers. An excessive depth of cut for the study area was assumed to be twelve feet. A lift station or pump station and the gravity Isewers which convey wastewater to it comprise what is known as a "subsystem" or "subarea."

Summary: To summarize a typical gravity sewer collection system, the components can be identified in their order of usage as follows: a. The wastewater leaves the building and travels through the service lateral to the gravity sewer main. b. The wastewater travels through the downward -sloping gravity sewer main which may change direction and/or combine with other gravity sewer mains in manholes. C. The gravity sewer mains discharge into a lift station where the wastewater is pumped into a pressurized pipeline called a force main. d. The force main conveys the wastewater directly to the wastewater treatment plant or to a continuation of the collection system at a higher elevation. 0 B. LOW PRESSURE SEWER SYSTEMS 1. General: Although gravity sewers are the most common method of collecting and transporting sewage, there are certain situations where conventional gravity sewer systems are not practical nor cost-effective. Where the installation of gravity sewers would be difficult due to the presence of rock, high water tables, instable soils, and/or topography, low pressure sewer systems may provide a practical alternative. Low pressure sewer systems tend to be more cost-effective in sparsely settled areas, recreational lake developments, and riverfront communities. Low pressure sewer systems generally consist of a manifolded force main system with a small pump station serving each residential or commercial establishment. The principal components of a low pressure sewer system include the pump stations and the low pressure force main system. Like a gravity system, the low pressure force mains discharge into a master lift station which pumps the wastewater to the wastewater treatment plant. 2. Pump Station: The pump stations for low pressure sewer systems are generally comprised of a single grinder pump (2 horsepower, 230 volt) inside a small fiberglass wetwell, piping and valves, liquid level sensors, and a control panel. When an existing dwelling is converted from use of a septic tank to a low pressure system, the pump station is oftentimes located in the existing septic tank after minor modifications. These modifications include the following: situating the pump station assembly into the septic tank; connection of the sewer service from the dwelling to the pump station; and abandoning the septic tank by L 7 I I 9 L punching a hole in its bottom and filling it with clean backfill (see Exhibit II -3). However, the pump station could be located anywhere in the vicinity of the existing septic tank provided the sewer service from the dwelling can be routed to the pump station. A small -diameter force main (i.e., 11/. to 11/z inches) is then run from the pump station through private property to connect to the manifolded force main system, usually located in the right-of-way or along the rear property line. When connecting a new dwelling to an existing low pressure system, the pump station may be located on private property or in the right-of-way, depending on the situation. Access onto private property to operate and maintain the pump stations and force mains is typically provided by a service agreement between the property owner and the municipality servicing the system. The FDER requirements for low pressure pump stations are as follows: a. A single pump (simplex) grinder station may serve only one house or business. b. An emergency generator receptacle is required in case of power outages. C. An audible and visual alarm is required for overflow warning. d. A valve is required to isolate each individual station from the force main to assist in repair or maintenance procedures. e. If a pump station is to serve more than one house or business, two grinder pumps (duplex) are required per station. f. The control panel must be located so that it is visible from the pump station, but not attached to the building structure. 0 r" 1 1'° r 4 P"4Y°' r ' P +""v rw� r"�"+ ow"" wwom map A"m go" CONTROL PANEL EXISTING BUILDING GRAVITY SERVICE FLOAT SWITCHES ffl-lu VALVE BOX W/ BALL VALVE a CHECK VALVE WET WELL GRINDER PUMP ///;/// ///;-5 /// EXISTING SEPTIC TANK (TO BE ABANDONED) I 1/2°P.V.C.

Low Pressure Force Mains: The manifolded low pressure force main system typically consists of pipe two to six inches in diameter. This pipe is typically strung along the right-of-way or along the rear property line of the establishments being served (see Exhibit H-4). If the pipe is to be strung along a roadway, parallel lines (i.e., one on each side of the road) may be constructed to avoid cutting the road numerous times to serve establishments on the opposite side of the road. Low pressure systems are generally not constrained by topography to the extent that gravity systems are. An existing low pressure system can be tapped into and extended as necessary to serve new customers, provided the existing system was adequately sized initially. The installation of low pressure systems typically does not cause as much disturbance as a gravity system because low pressure systems generally consist of smaller -diameter pipe installed at shallower depths. I 4. Summary: To summarize a typical low pressure system, the components will be a identified in the progressive order of their usage as follows: a. The wastewater is discharged from the building through a gravity flow sewer service pipe into the wetwell of the pump station. b. The wastewater is pumped from the wetwell through a small diameter, low pressure service pipe which discharges into a larger diameter, low pressure force main.

Minimal operation and maintenance requirements. b. Not affected by power outages. C.

Not subject to infiltration/inflow. C. Less disruption during construction. d. System is conducive to expansion if force mains are adequately -sized initially. e.

Easements or service agreements required to construct and operate on private property. C. Access to pump stations on private property can be difficult. d. Subject to power failures. e. Aboveground control panels may be aesthetically unpleasing. f. Connection of future customers typically requires installation of new pump station. i 12 III. ANALYSIS A. In order to evaluate the area proposed for sewer service, various sources of technical information were gathered and analyzed. This information included recent aerial photographs of the study area, which were pieced together to form a photographic map (i.e., "mosaic") from which buildings and roadways could be identified. Also, topographic surveys were performed to determine ground elevations throughout the study area. As -built drawing information of the existing sewer collection facilities in the study area was also analyzed and incorporated into the proposed layout. In addition, site visits were made to evaluate special situations which could not be identified from other available resources. All of this information was utilized in developing the proposed configuration of the sewer Icollection system. B. SUBAREA DELINEATION A "subarea" is defined as that portion of the sewer service area which is served by a specific master lift station. A "master lift station" is defined as a lift station capable of pumping the wastewater collected from a large portion of the collection system directly to the wastewater treatment plant. Some of the deciding factors utilized in delineating the various subareas include the density of development to + be served, the presence of existing sewer systems, topography, minimizing the L 13 depth of cut for gravity sewers, minimizing the number of master lift stations required, and the location and availability of right-of-way and easements. Each subarea is typically served by its own master lift station. In certain portions of the study area, it may be obvious that one type of sewage collection system is more feasible than another. For example, in areas where the buildings to be served are situated closely together, the best method of sewer collection tends to be gravity sewer. In areas where the buildings to be served are less densely grouped or are spread out over long distances, low pressure sewer systems tend to be more economical. Topographic constraints may also make a gravity sewer system unfeasible. For instance, the grade of the land may be in 3 the opposite direction of the required slope of the gravity sewer, which would 3 result in excessive depths of cut. See Exhibit IV -1 for the delineation of the various subareas. tC. SPECIAL CONSTRUCTION SITUATIONS Several unique construction situations in the study area will be encountered. Foremost of these is the fact that Indian River Drive is comprised of twelve (12) Y inches of concrete with up to six (6) inches of asphalt topping. Special machinery may be required to separate the asphalt from the concrete (e.g., milling machine) and to break up and remove the 12 -inch -thick concrete. In addition, the cost to dispose of this waste asphalt and concrete must be considered in the analysis. It is possible that the County may have use for the broken concrete as riprap. L14 IHowever, for the purpose of this study, it was assumed that the construction contractor would have to dispose of any excess concrete or asphalt at his own expense. Where gravity sewers were evaluated on Indian River Drive, it was assumed that the entire width of road would have to be replaced. Where a low pressure system was evaluated, it was assumed that the low pressure main would Ibe installed adjacent to the roadway or along back lot lines. IAnother construction situation which may be encountered is the presence of groundwater. A high groundwater table can significantly increase the cost of installation of gravity sewer systems due to the need to install dewatering equipment. For this reason, it was assumed that gravity sewer depths in excess of 12 feet would be avoided where possible. The encountering of a high groundwater table is more likely to be a problem in the southern half of this study area along the river. The encountering of rock formations can also significantly increase the cost of installing sewer collection systems, particularly gravity systems. Conversations with local well drillers indicate that minimal rock should be encountered. However, the well drillers indicate the presence of a hard shell layer, and it is recommended that periodic borings be performed prior to construction to verify the location and depths of this layer. Another situation specific to the study area which will have an impact on design and construction is the availability of rights-of-way and easements. On portions 15 of Indian River Drive, the width of the right-of-way is the same as the width of pavement. Therefore, any construction along Indian River Drive in these areas would have to occur within the limits of pavement whether a gravity system or low pressure system was being installed. Most of the sewer collection system proposed will be constructed in existing rights-of-way and easements. However, there will be a need to acquire additional rights-of-way/easements, or use a service agreement, to construct portions of the proposed system, particularly for the areas where private roadways are encountered. D. DEVELOPMENT OF UNIT COSTS In order to perform a cost comparison of gravity sewer systems versus low pressure sewer systems, unit costs for the various items of construction/restoration associated with this type of work were solicited from area utility contractors and equipment representatives. Recent bids received for similar work and engineering estimates were also utilized in developing the unit costs. The unit prices utilized in the analysis are presented in Table III -1. Operation and maintenance costs for gravity sewers were estimated from budgetary data supplied by the City of Vero Beach. For 1991, the City of Vero Beach budgeted $258,000.00 for the repair and maintenance of its gravity sewers and manholes. This figure does not reflect any costs associated with pump a stations or force mains. The total length of gravity sewer in the City of Vero Beach's system is 563,690 feet, which results in an annual operation and 16 3 maintenance cost of $0.46/fooUyear. However, over 75 % of the City's system is comprised of vitrified clay pipe, and much of this pipe is more than 30 years old. Vitrified clay pipe is costly to repair and maintain. With a gravity system comprised of new PVC and ductile iron pipe, the cost to repair and maintain it will be reduced substantially over the 20 -year life cycle. Therefore, an annual operation and maintenance cost of $0.25/foot/year for gravity sewer was assumed. Operation and maintenance costs utilized for the simplex grinder pump stations were derived from the actual operation and maintenance costs for the County's Rockridge system. This low pressure system has been in operation for approximately two years. The average cost to operate each simplex grinder pump station is $100.00 per year. Assuming pump replacement is required on the average of every ten years and that a replacement pump costs $450.00, this adds $45.00 to the annual operation and maintenance cost of each station. Therefore, each simplex grinder pump station will cost an average of $145.00 per year to operate and maintain. These costs are comparable to those obtained from pump station manufacturers/suppliers and from case studies of similar systems. The cost to operate and maintain a duplex grinder pump station is assumed to be approximately 50% higher, or $225.00 per year. Operation and maintenance costs for the master lift stations in each subarea have been derived from County records of similar size stations and will cost an average of $2,500.00 per year to operate and maintain.

SUBAREA ANALYSIS Each subarea was analyzed in a street -by -street progression in which each street was evaluated for both gravity sewer and low pressure sewer, unless one method was clearly unfeasible. Although project cost is usually the basis for deciding which sewer system to use, it is important that the compatibility of each system Iwith adjoining systems be considered. A combination of both gravity and low pressure sewer systems will usually result in the most cost-effective sewer system. Low pressure sewers .offer the convenience of discharging into a gravity sewer system, while the opposite is not possible without the construction of a lift station. Therefore, when analyzing a subarea on a street -by -street basis, it is not possible to choose the sewer system x for each street by cost alone because the sewer system must be compatible with those of the adjoining streets. When a gravity sewer system is installed, a service lateral will be installed for each individual lot that fronts the sewer line regardless of whether a building 1 currently exists there or not. Therefore, when property owners decide to build on their lots, a lateral would be readily available for a service connection. On the other hand, when a low pressure sewer system is constructed, grinder pump stations would be installed only for buildings which exist at the time of the i system's construction. If property owners decide to build on their lots in the future, a grinder pump station would have to be purchased and connected to the 4 low pressure pipe system. 21 d In summary, a gravity sewer system provides service to all properties which it fronts without requiring additions to the system. Low pressure sewer systems serve only existing buildings, and any new development would require the purchase of additional pump stations which would have to be added to the system as the properties are developed. When evaluating the cost estimates for a sewer system on a street -by -street basis, the continuity of the sewer system must be maintained. In some areas gravity sewer may appear to be the most cost-effective method of sewer collection due to the density of the surrounding buildings. However, the denser residential areas may be separated by short distances of sparsely populated areas where low pressure sewer systems appear to be more cost-effective. Under those circumstances, the use of gravity sewer may be recommended in lieu of low pressure sewer to benefit from the economic savings of the gravity sewer system in the more densely populated areas.

Subarea 2 Summary Subarea 2 consists of the area between U.S. 1 and the Indian River, being bounded on the north side by 129th Street North and on the south side by the intersection of Old Dixie Highway and U.S. 1. The presence of the elevated ridge along U.S. I gradually diminishes in this subarea. However, the topography continues on a downward slope from U.S. I toward the Indian River. The only existing sewer system within Subarea 2 is in the El Capitain Mobile Home Park. This park has a gravity sewer system which flows into a wastewater "package" treatment plant at the park's entrance on Riverside Drive. This package plant will be abandoned, and a duplex grinder pump lift station will be constructed in its place to pump the wastewater a short distance into the proposed gravity sewer system. The analysis indicates that a gravity sewer system will be the most cost- effective method of serving the denser central area of the subarea, while low pressure systems will best serve the outer edges of the subarea where the areas are sparsely developed. 32 1 El The estimated cost of the gravity sewer lines for Riverside Drive from 129th Street North to Davis Street is higher than the cost of a low pressure sewer system. However, the benefit of being able to use gravity sewer on the adjoining streets and eliminating an additional lift station results in a much lower total cost for the entire subarea. Subarea 3 Summary Subarea 3 is comprised of the area between U.S. 1 and the Indian River south of Captain Hiram's Restaurant and north of the private mobile home park on the north side of Washington Street. The area has gradual slope from U.S. 1 toward the Indian River while remaining relatively flat along Riverside Drive. The existing sewer systems in this area consist of a small wastewater treatment plant which serves the Oyster Point and Oyster Bay Condominiums. This wastewater plant would be abandoned and its flow diverted to the existing lift station at the Sebastian Inlet Marina (Captain Hiram's) where it will be pumped into the existing force main along Riverside Drive. 33 I Within Subarea 3, the denser developments are better served by gravity sewers, while the sparsely developed Riverside Drive is better suited to a low pressure sewer system. The gravity sewer system along Riverside Drive from the mobile home park to Main Street is slightly more expensive than a low pressure sewer system. However, the additional cost of the gravity sewer system can be justified because it provides additional sewer service connections for future buildings without the expense of purchasing the additional grinder pumps required for a low pressure system. 1 5. Subarea 4 Summary Subarea 4 is the area between U.S. 1 and the Indian River, bounded on the north side by Martin Avenue and on the south side by the D.O.T. drainage canal north of WalMart. The area has a gradual downward slope from U.S. 1 toward the Indian River, while Riverside Drive remains essentially flat. This subarea has no existing gravity or low pressure sewer systems. The analysis indicates that gravity sewer is slightly more cost-effective than a low pressure sewer system for this subarea. Although the Riverside Drive gravity sewer appears to cost more than a ( low pressure system, the savings in connecting the gravity sewers on 1 34 L Cleveland Street, Coolidge Street, and Harrison Street justify the additional cost. Also, cost savings of using a gravity sewer system to serve the Martin Avenue area justifies the higher cost of the gravity sewer line on Martin Avenue. One section of this subarea that requires special consideration is the block between Fellsmere Road and Coolidge Street. This block is currently undeveloped and therefore does not require any grinder pump stations for the low pressure sewer system cost estimate. This must be considered in the cost analysis because the gravity sewer system can provide sewer service to the entire block without any future expenditures, while the low pressure sewer would require the future purchase of a grinder pump station(s). 35 F. ALTERNATIVE LAYOUT FOR 100% GRAVITY SYSTEM WHEREVER PRACTICAL As an alternative to the combination gravity/low pressure system recommended for the study area, a 100% gravity system, in all areas practical, was evaluated. The proposed layout for this gravity system is presented in Exhibit IV -2. The necessary inclusion of additional master pump stations for this alternative required the creation of three additional subareas: Subareas 1C, 3A, and 3B. Subarea 1C consists of a portion of Subarea 1B of the recommended layout (Exhibit IV -1). Subareas 3A and 3B comprise Subarea 3 of the recommended layout. In this alternative, a new master lift station would be constructed in the vicinity of the El CM I I I I d I I I I I I Capitain Development to service Subarea 1C. Also, the existing lift station at Captain Hiram's would be refitted with new pumps and would serve as the master lift station for Subarea 3A. All other master lift stations would remain in the same location as indicated in the Recommended Layout of Exhibit IV -1. The Gravity Wherever Practical Alternative (i.e., Exhibit N-2) results in a present worth cost that is $294,725.00 more than the recommended alternative (i.e., Exhibit IV -1). Ultimate selection of which type of sewer collection system to utilize in the Indian River County portions of the study area will be determined by the County Commission. Selection of the type of collection system to be utilized for the City of Sebastian's portion of the study area will be made by the Sebastian City Council. A comparison of the costs for each subarea for the two alternatives is presented in Table III -3. For comparison purposes, Subarea 1B in the combination Gravity/Low Pressure Alternative is equivalent to Subareas 1B and IC of the Gravity Wherever Practical Alternative. Also, Subarea 3 of the Gravity/Low Pressure Alternative is equivalent to Subareas 3A and 3B of the Gravity Wherever Practical Alternative. 37 TABLE 111-3 COMPARISON OF COSTS BETWEEN GRAVITY/LOW PRESSURE ALTERNATIVE AND GRAVITY WHEREVER PRACTICAL ALTERNATIVE GRAVITY/LOW PRESSURE ALTERNATIVE Subarea Capital Cost ($) O & M Cost ($/Yr) Present Worth IA 339,640 1,845 357,750 1B 1,143,895 5,370 1,196,585 2 505,380 5,005 551,515 3 372,250 5,370 424,805 4 536,930 4,435 580,445 5 589.750 8.890 677.055 TOTAL 3,487,845 30,915 3,788,155 GRAVITY WHEREVER PRACTICAL ALTERNATIVE Subarea Capital Cost ($) O & M Cost ($/Yr) Present Worth IA 339,640 1,845 357,750 _ 1B 783,760 2,910 812,295 1C 490,940 2,460 505,425 2 539,280 4,000 575,510 3A 156,040 2,650 182,100 3B 363,100 2,975 392,300 4 536,930 4,435 580,445 5 589.750 8.890 677.055 TOTAL 3,799,440 30,165 4,082,880 in f IIV. SUMMARY AND RECOMMENDATIONS H I I t I R A. GENERAL The most cost-effective means of providing sewer collection to the study area is a combination of gravity and low pressure systems. Generally, the northern portion of the study area is better suited for a gravity system due to its density of development, the presence of existing gravity sewer, and topography in that area. The southern portion of the study area is better suited for a low pressure system due to the relatively sparse development and the topography of the area. The recommended layout of the proposed sewer system is presented in Exhibit IV - 1, Gravity/Low Pressure Alternative. Generally, the most cost-effective type of sewer collection system, based on present worth analysis, was recommended for each subarea. The inherent advantages and disadvantages in comparing gravity systems vs. low pressure systems tend to even out so that selection of the type of system is made on the basis of present worth. Gravity systems tend to cause more disturbance during their construction, but once they are in place and operational, they are almost unnoticeable. Low pressure systems cause much less disturbance during construction but require more attention and maintenance during their operation. 39 A q I t t L I B. COST SUMMARY The costs associated with the Gravity/Low Pressure Alternative and the Gravity Wherever Practical Alternative are summarized in Table IV -1. In this table, the approximate total square footage of each subarea has been included for both of the alternatives. The individual residences and businesses in the various subareas will be assessed the capital cost of the selected sewer collection system based on the square footage of property owned. The precise method for assessment for the Indian River County portions of the study area will be determined by the County's Utility Department subject to the approval of the County Commission. The method of assessment for the City of Sebastian's portion of the study area will be determined by the Sebastian City Council. In the Combination Gravity/Low Pressure Alternative, Subareas 2, 3, and 4 comprise the City of Sebastian portions of the study area. The remaining subareas are located within Indian River County's portion of the study area. In the Gravity Wherever Practical Alternative, Subareas 2, 3A, 313, and 4 comprise the City of Sebastian portions of the study area. The remaining subareas are located within Indian River County's portion of the study area. w r ow" o"W ow" ftwo am* w ria war TABLE ry-1 SUMMARY OF COSTS COMBINATION GRAVITY/LOW PRESSURE.

McCain Capital Projects Engineer Indian River County 1840 25th Street Vero Beach, Florida 32960 RE: Indian River County Indian River Drive Sewer Study Supplement for the City of Sebastian Kimball•Licyd Project No. 90-279 Dear Mr. McCain: ENGINEERS ARCHITECTS — PLANNERS — SURVEYORS o At your request, we have prepared cost estimates for providing sewer service exclusively to those property owners within the Sebastian City Limits who have previously paid their sewer impact fees. The study area consists of that area bounded on the north and south by the Sebastian City Limits, on the west by U.S. 1, and on the east by the Indian River. Two different sewer -alternatives for the study area were evaluated. In the first alternative, only those portions of the recommended layout from the Indian River Drive Sewer Study necessary to serve those property awners who have previously paid their sewer impact fees would be constructed. Gravity sewers would be installed at such depths so that the system could be economically expanded to serve the entire study area at a future date. Sewer services would be provided to all properties fronting a gravity sewer line, regardless of whether the property owners had paid their impact fees, in order to make any future connections more economical. The master lift stations identified in the Indian River Drive Sewer Study have been reduced to less costly duplex grinder pump stations because the lower sewage flows can be easily handled by the smaller pump station. In the event that the remainder of the sewer collection system as identified in the Indian River Drive Sewer Study is constructed at a future date, then the duplex grinder pump stations would have to be upgraded to nester lift stations to handle the increased flows. In some instances, construction of a gravity system, even though recomTended in the Indian River Drive Sewer Study, would not be practical because the properties to be served are isolated and are a great distance from any other property to be served. Where this occurs, a simplex grinder pump station would be constructed which would be connected directly to the large diameter force main on Indian River Drive. This would be done in order to avoid running excessive lengths of lea pressure force main to a distant duplex lift station. O= L RCncRT R:::n+•L. d ,:SSOrIAT_S I I March 12, 1991 William F. McCain Indian River Drive Sewer Study Supplement Page 2 The second alternative that was evaluated was for determining the most econcanical r sewer collection system to serve only those property owners who had paid their ■i sewer impact fees, but with no plans for expansion of the system to serve future customers. Because of the scattered arrangement of the properties to be served, a low pressure system would tend to be "the most economical sewer collection system for this alternative. Some of the simplex and duplex lift stations associated with this alternative would be connected directly into the existing 10 -inch force main on Indian River Drive. This is to avoid running excessive lengths of lea pressure force mains with few or no other stations interconnected along the way. There would be no master lift stations constructed with this alternative. However, 16 duplex grinder pump stations and 15 siplex grinder pump stations would be required. Also, a small portion at the south end of the study area would be more economically served by a gravity system due to the high density of development in this area. The estimated construction costs for the first alternative (i.e., recmmnerdled layout from Indian River Drive Sewer Study to serve only property owners who have paid their sewer mast fees) and the second alternative (i.e., least costly layout to serve only property owners who have prepaid their sewer impact fees) are presented in Table 1 and Table 2, respectively. The unit prices utilized in these cost estimates are the same as were presented in the Indian River Drive Sewer Study. Operation and maintenance costs were not included in this analysis. The total capital cost for the first alternative is $714,775, while the total capital cost for the second alternative is $651,850. These capital costs include construction cost with 205. contingency and engineering costs (12%). l Please contact me if you wish to discuss this matter further.
