Laguna County Sanitation Dsistrict - Tertiary Treated water Tank Projecct Amendment to the Total Dissolved Solids Reduction and Recycled Water Project (BRINEX)

The LCSD is proposing to install the tertiary treated water holding facility analyzed in the April 2000 Final MND for the Total Dissolved Solids Reduction and Recycled Water Project (Brinex). The tertiary holding facility is intended to provide the daily supply of recycled water to various users. However, instead of constructing the open storage pond/reservoir previously evaluated in the approved Mitigated Negative Declaration, LCSD has received grant funding for, and proposes to construct a total of four 1 million gallon aboveground storage tanks (approximately 80' diameter and 35' high) to replace the open pond. Water not used would be pumped to a larger long-term storage reservoir and is irrigated on the LCSD pasture. Storage in the aboveground tanks is preferred because the tanks would protect the tertiary treated water from being recontaminated from windborne debris, soil contact, and bird and rodent influence. Initially, under funding obtained from Proposition 50, only one tank would be installed and when additional funding is obtained the remaining tanks would be installed. The tanks would be located in the disturbed area of the plant just to the south and west of the location of the previously proposed pond. A new small 30,000 gallon below ground clearwell structure with pumps would also be constructed to fill the new tanks. The clearwell strcuture would be located in the previously approved plant expansion area immediately north of the previously constructed treatment trains. The tanks would be connected to the existing on- and off-site pipeline network.
