Document Description
The Agency is considering three build Alternatives for the proposed project. Alternative 1, the Agency's preferred Alternative, proposes to convey secondary treated water via a new pipeline from the Central Treatment Plan to the North Treatment Plant. Alternative 2 proposes to convey raw wastewater from the Central Treatment Plant to the North Treatment Plant. Alternatives 1 and 2 include optional pipeline from the southern Sea Ranch area to the Central Treatment Plan and optional reservoirs and piping for storage and conveyance of tertiary treated water from the Gualala Community Services District Treatment Plant. New pump facilities would be added at the existing treatment facilities. Alternative 3 proposes to expand the Central Treatment Plant. The expansion would include the construction of an additional storage pond and expansion of the irrigation disposal area at the Central Treatment Plant from 4 acres to ~12 acres. No new pipeline would be required for Alternative 3.
