Recommended Action
Approve Agreement No. 2016-21, Professional Engineering Services, Permitting, Construction documents and limited CEI services for Chemical Feed Improvements at Myakkahatchee Creek Water Treatment Plant, with Hazen and Sawyer, P.C. of Sarasota, Florida in the amount of $64,390 plus $5,000 contingency for a total amount of $69,390.
Background Information
The City is currently experiencing the following challenges: 1) the anhydrous (i.e. gaseous) ammonia system is a maintenance challenge and safety concern; and, 2) maintaining appropriate chlorine and ammonia residuals in the distribution system is difficult. The City has examined various options for ammonia addition (e.g. anhydrous ammonia, aqua ammonia, and ammonium sulfate) and has determined ammonium sulfate to be the best option. Additionally, a system which will allow for flow-pacing of the ammonia addition will greatly improve the Utilities’ ability to manage chlorine and ammonia residuals in the distribution system.
There are many benefits to changing to a flow-paced ammonium sulfate system. Safety is one benefit as ammonium sulfate has less safety concerns compared to anhydrous ammonia. A second anticipated benefit is improved ability to manage residuals in the distribution system, which will decrease the amount of operational flushing required. The City is currently under a Remedial Action Plan (RAP) with Southwest Florida Water Management District (SWFWMD) to reduce flushing. Utilities’ staff anticipate that the proposed changes to the ammonia feed system will make great strides in relieving Utilities of this RAP. Once flushing is reduced the level of service Utilities can provide is expected to increase.
Proposals were requested from consulting engineering firms for professional services needed for the chemical feed system improvements. Two (2) proposals were received with Hazen and Sawyer selected as the most qualified firm. Negotiations of the scope and fee were conducted resulting in this Agreement. The Agreement includes the design, permitting and construction plans and specifications, as well as limited CEI services. The task associated with permitting will not be used if it is determined permitting is not required.
