South County Regional Water Treatment Plant
12 MGD Reverse Osmosis (RO) Expansion, Collier County, FL
Expanded water treatment capacity; ability to accommodate potential future increases in raw water salinity; use of excess concentrate disposal pressure to drive interstage pumping, reducing electrical energy demand by 450 horsepower; effective taste and odor control; larger normal and emergency power supply systems; potential for optimizing finished water quality by blending treated water from the existing lime softening system with that of the osmosis system.
The population of Collier County had increased drastically over a ten year period and the growth projected to continue which produced tremendous stress on both water and wastewater infrastructure. Collier County needed to increase the capacity of its reverse osmosis (ROP) water treatment plant and upgrade the automation with electrical reliability at the existing (LSP) lime softening treatment plant to meet the County’s demand.
SCOPE OF SERVICES
Seeking a company with extensive water treatment plant expertise, this client chose Poole & Kent Company of Florida to expand an existing 8-mgd (million gallons per day) reverse osmosis (RO) water treatment plant to a total capacity of 20-mgd and upgrade the existing lime softening treatment plant’s automation with electrical reliability. During construction, Poole & Kent’s work included the following major elements:
Due to the critical nature of the ROP expansion phase, Poole & Kent Company of Florida built the six new RO skids on a fast-track basis. The company had all skids completed and in service within 14 months from the notice-to-proceed (NTP) date. The LSP expansion phase was completed within 20 months from NTP.
Originally built in 1984, the South County Regional Water Treatment Plant has undergone several expansions that have brought its current production to 32-million gallons of drinking water per day. Of these, 12 million are produced through lime softening water treatment and 20 million through reverse osmosis.
