The Los Osos Community Services District water system uses five source wells. Water delivered to the LOCSD customers is groundwater that originates from the Los Osos Valley Basin. The groundwater basin is a collection of local drainage basins, streams, 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 naturally occurring minerals or substances resulting from animals or human activity. Groundwater is normally very clean and is simply disinfected to help minimize the chance of any viral and bacterial contamination.
Each well is equipped with on-line apparatus for operation and monitoring purposes. An alarm system is integrated in the monitoring process to notify operators if there is a problem at any well site or District facility. Two District wells have additional filtration equipment designed to remove naturally occurring iron and manganese found in these two wells to aesthetically acceptable levels. One upper aquifer well has the nitrates removed prior to distribution into the water system.
The Utilities Department operators are responsible for treatment of the six groundwater supply wells. Crews are also responsible for water quality monitoring, sampling, distribution system repair/maintenance, meter reading and regulatory reporting compliance. The delivery of water to the District’s water customers is conveyed through a network of over 27 miles of water mainlines, utilizing three (3) water storage tanks connected through approximately 2,750 water service lines and meters serving residences and businesses. Included in the domestic water service infrastructure are 3 water storage tanks, 162 fire hydrants with some 558 valves that require periodic maintenance and inspection. These services provided by Utilities Department personnel not only assure delivery of clean, safe and potable drinking water, but also provide the water essential for fire fighting.
