Project Overview

Central Coast Blue is a regional recycled water project that will develop a sustainable water supply and protect the Santa Maria Groundwater Basin (SMGB). The recent drought drastically impacted water resources for the Five Cities communities and highlighted the need for a sustainable, drought-proof source of supply to ensure that reliable water supplies will be available for future extended droughts. Currently the water from the Pismo Beach Wastewater Treatment Plant (WWTP) and the South San Luis Obispo County Sanitation District (SSLOCSD) WWTPs is being treated and discharged to the ocean. Central Coast Blue will provide an opportunity to capture this lost water and use it to recharge the SMGB to create a drought proof, sustainable water supply for the community.

What is the Project?

Central Coast Blue will include construction of an Advanced Treatment Facility to treat water from the City of Pismo Beach and the SSLOCSD WWTPs to produce purified water that is purer than most bottled waters. The purified water will be pumped to injection wells and injected into the groundwater basin to supplement the natural groundwater supply. Central Coast Blue will provide a new locally controlled, drought proof water supply for the Five Cities communities.

How Will This Project Benefit Me?

By recharging the local groundwater basin with purified water, Central Coast Blue will provide the community with a constant source of water supply that is independent of climate or environmental factors and can protect the groundwater basin from seawater intrusion. The water cycle is a naturally balanced process. When cities and towns use water from the environment, the water is typically replenished by rainfall or melting snow. However, if the city or town grows or if there is less rain and snow, then there will be an imbalance in the local water cycle. We can solve this problem and balance the local water cycle by incorporating purified, recycled water into the water supply. Adding purified water enhances local supply reliability and helps protect us from droughts by diversifying our supply sources and keeping us from becoming too reliant on any one source of water. Central Coast Blue project will give local citizens confidence that they will have a sustainable and environmentally friendly water source to fuel their daily lives and those of their children and grandchildren.

One Community, one water, one future.
