What is the City doing?

The City has completed a study of the feasibility of groundwater within the Conejo Valley as an alternative to imported water for irrigation and potable use. The study concludes that roughly 10 percent of current water usage citywide could be offset with groundwater on a long-term basis.

A phased approach to implementing this new local water source is recommended, with new groundwater wells constructed for irrigation of parks and schools as the first phase. Later phases may include groundwater treated for use as a potable supply.

Where is this City doing this work?

New groundwater wells may be constructed throughout the City. The initial construction phase would likely be focused at large parks and schools to offset potable water used for irrigation groundwater.

Why is the City doing this?

The cost of imported water continues to increase, with the price having doubled in the last 7 years. At the same time, reliability of this source is not as certain due to drought and environmental challenges. A local groundwater source would be more reliable and cost less than imported water.

What are the impacts from this project?

Because there are three main water suppliers within Thousand Oaks (California American Water Co in Newbury Park, City Water System in central Thousand Oaks, and California Water Service Co in Westlake), arrangements still need to be made as to who will finance, construct, own, operate and maintain new groundwater wells and related facilities. The study concluded that better quality groundwater exists in the western areas of the city, which would result in lower costs due to lower treatment requirements.

When is the City doing this work and how long will it take?

The study recommends a phased approach to implementing a new groundwater source. Initial groundwater wells used for irrigation could be in place in 1 to 2 years. Wells requiring treatment will take closer to 5 years to bring on line. For additional information on Groundwater, click here.
