Water
Delta SunsetResponding to difficult economic times for the region and state, Western Municipal Water District’s Board and management team work diligently to reduce costs and increase efficiencies to keep rates as low as possible as we deliver a clean and reliable supply of water. Some examples of these cost-control efforts include…



  • In 2010, we negotiated an agreement with the city of Riverside to acquire local groundwater and pump it the short distance to our service area at a rate lower than that of imported water, which travels hundreds of miles to get to your tap. This agreement saves you money.
  • Western addressed the long-term cost of employee retirement benefits, achieved cost-savings and enacted cost-controls on health benefits offered to employees.

Now and in the future, Western is committed to providing secure, safe water at the best price possible through increasing efficiencies, investing in technology and expanding local sources of water.
Western will implement a rate increase on Jan. 1, 2015. On May 19, 2010, Western adopted Resolution No. 2665, authorizing annual adjustments to our water service fees and charges. These annual adjustments are necessary to avoid operational deficits and depletion of reserves while continuing to address infrastructure needs and water quality improvements.

The annual adjustments, which Western will make Jan. 1, 2015, include:

  1. Increases in rates and charges related to the purchase of imported water from the Metropolitan Water District, which are imposed on Western (“Metropolitan Water District Pass Throughs”). This increase includes a Readiness-to-Serve (RTS) Charge assessed to Western from Metropolitan Water District. Most of the water Western imports into our service area to meet customer needs is purchased from Metropolitan Water District. Metropolitan Water District uses RTS charges collected from Western and other member agencies to pay for emergency and standby storage facilities, such as Diamond Valley Lake. These facilities help ensure a safe, reliable water supply for our customers. Western’s share of the RTS Charge has increased substantially, requiring Western to now pass it through to our customers as a fixed charge that will appear on your monthly water bill. All revenue collected from this charge is forwarded to Metropolitan Water District.
  2. Increases in costs of operations and maintenance (“Inflationary Adjustments”).
  3. Increases in the rates imposed on Western by energy providers to pump water (“Energy Pass Throughs”).
  4. The annual increase to the Water Reliability Charge (Riverside Service Area customers only).

The adjustments will impact the rates of the Water Charge, Pumping Charge, Fixed System Charge, Water Reliability Charge and Metropolitan Water District RTS Charge components of Western’s water service fees.

Water GlassHow Water Rates Are Determined
The Board of Directors establishes Western's water rates, fees and charges, and reviews them, along with staff, to ensure that Western continues to operate cost-effectively while delivering a safe, reliable water supply to your tap.
 
The water bill generally consists of water-use related charges and fixed charges. The water use charges vary based on the number of "units" of water delivered to your property; one unit is equal to 748 gallons. These charges cover the cost for Western to purchase the water, which includes the cost of treating the water to ensure that it's safe to drink, and the cost of pumping the water to your property. The Water Reliability Charge is an investment in the safety, security and viability of our regional water system with generated revenue dedicated to funding projects related to increasing water system capacity and improving the long-term sustainability of the water supply. The fixed system charge is a monthly fee that covers operations, maintenance, repair and replacement costs of the entire water system. The MWD Readiness-to-Serve charge is a monthly fee that is paid to the Metropolitan Water District (MWD).  Metropolitan Water District uses this revenue to help pay for emergency and standby storage facilities, such as Diamond Valley Lake. These facilities help ensure a safe, reliable water supply for our customers.
