Our San Diego County Coverage Area

Imports, Desalination and Recycling

The region buys most of its water from the Colorado River and Northern California, adds output from the Carlsbad Desalination Plant and expands recycled water and purification projects. Many districts have no local source at all. Check your bill for your provider.

Hillside Pressure Zones

Steep streets create large pressure differences. High pressure strains fixtures and heaters, and a regulator and gauge help protect them.

Salt Air Along the Coast, Heat Inland

Coastal air corrodes hose bibs, valves and heater bases, while inland valleys bake outdoor lines. Test shutoffs yearly and shade or insulate exposed pipe.

Canyon Homes, Septic Lots and Wildfire Season

Canyon and rural-edge lots may use private wells or septic systems, and wildfire season stresses outdoor lines. Check hose bibs before fire season and know where the main shutoff is.
