The Murrieta City Council formed the Water Infrastructure Ad-Hoc Committee (Water Committee) in October of 2017 to address water supply and infrastructure concerns in the western portion of the City. In December 2017, the Water Committee unanimously determined that the most appropriate course of action was to ask LAFCO to conduct a detailed Municipal Service Review. In February 2018, the City formally requested a Focused Municipal Service Review (FMSR).
On December 6, 2018, the Local Agency Formation Commission (LAFCO) approved a consultant agreement with West Yost Associates to prepare a Murrieta Area Focused Municipal Service Review (FMSR) for the area that generally comprises the Murrieta Division of Western Municipal Water District. The involved agencies, Western Municipal Water District (WMWD), Eastern Municipal Water District (EMWD), and Rancho California Water District (RCWD) and the City of Murrieta agreed to fund equal portions of the cost of the Murrieta Area FMSR agreement.
The Riverside Local Agency Formation Commission (LAFCO) completed their final independent municipal service review (MSR), which was requested by the City of Murrieta to determine what district is best suited to provide service: Western Municipal Water District, Rancho California Water District or Eastern Municipal Water District.
