It’s been one year since the City of Riverside and Western Municipal Water District (WMWD) executed a Regional Water Partnership deal that allowing WMWD to purchase surplus Riverside groundwater supplies that are part of the City’s Court-adjudicated water right in the San Bernardino Basin Area. In its first calendar year, the partnership has resulted in a $2.6 million savings for Western and $4.5 million in revenue for the City. It has also brought an additional 2.4 billion gallons of local groundwater to WMWD’s customers, which is enough annual water supply for about 15,000 single-family homes. The deal will also help keep water rates as low as possible in the years to come for both agencies.
