WRCOG Energy Efficiency and Water Conservation Program

WRCOGThe Western Riverside Council of Governments (WRCOG), in partnership with SAMAS Capital, has developed a financing program that allows businesses in Western Riverside County to implement energy and water efficiency improvements using low-interest loans that will be repaid over time through annual property tax payments.

California law allows for local jurisdictions to enter into contractual assessments with property owners for such improvements; WRCOG has implemented a regional program on behalf of its member jurisdictions in order to centralize responsibilities and realize cost savings.

The City of Corona is proud to be a member of WRCOG and these programs are available to all Corona residents and businesses regardless of your water or energy provider.
