LOCSD Water System Uses Five Source Wells

Water delivered to LOCSD customers is groundwater that originates from the Los Osos Valley Basin. The five water well sites are known as the Eighth Street Well, Third Street Well, 10th Street Well, Palisades Well and South Bay Well. The groundwater basin is a collection of local drainage basins, streams and creeks and natural percolation from rain, agriculture and domestic use. Water is cleaned through a natural filtration process as it trickles down through the ground. During this process, water may also pick up contaminants found in the soil, either natural or man-made. Groundwater is normally very clean and is simply disinfected to help minimize the chance of any viral and bacterial contamination.

Each well site is equipped with on-line equipment for operation and monitoring purposes. An alarm system is integrated into the monitoring process to notify operators if there is a problem at any well site or District facility. The South Bay and Eighth Street wells have additional filtration equipment designed to remove iron and manganese found in these two wells to aesthetically acceptable levels.
