The San Diego County Water Authority released a proposed water purchase agreement for a planned seawater desalination plant in Carlsbad that’s designed to reduce the area’s dependence on water sources vulnerable to drought.
That opens a public review period of the agreement that includes meetings for area residents on Oct. 2 and Oct. 10 to deliberate on the proposed deal. If approved, the desalination project would account for about 7 percent of regional supplies and one-third of locally generated water in San Diego County.
The water authority’s board has investigated desalinated water as a supply source for almost 20 years. It said the extra costs from the new water source, including improvements to the authority’s pipelines and treatment plant to accommodate the new supply, would add about $5 to $7 a month to the average household’s water bill by 2016.
