Dear Mr. Votapka:
This letter constitutes our engineering proposal to design, permit, inspect, certify and prepare
record drawings for the installation of an ammoniation system at the General Development
Utilities, Inc. (GDU) Filbert Street Water Treatment Plant (WT?) for the purpose of
trihalomethane control. The ammoniation feed system will quench the trihalomethane
formation reaction and limit the formation potential of the compound in the drinldng water.
The cost for survey of the site for which the improvements are to be. placed is $650. The final
design drawings and specifications will be prepared on behalf of the City at a cost of $7,500.
The cost for the permit fee to the Florida Department of Environmental Regulation (FDER) is
$4,000, and the preparation of the permit application is $500, for a total of $4,500. The cost
of the day of inspection, preparation of record drawings and certification to FDER is $850.
The cost of the preparation and coordination with the ammonia supplier and rental agreement
with the ammonia supplier for facilities located at the WTP site to be provided by the ammonia
supplier is $1,000. The total survey, engineering, permitting and technical services cost for
this assignment through completion and record drawings is $14,500.
