Investing in reliability

Drinking Water

Wastewater (Sewer)


Western serves an area where droughts are a regional reality. Increasing local water supplies and regional sustainability, and maintaining critical infrastructure, are vital to making sure that Western customers have a system and water supply resource they can rely on. In the past five years, Western has been awarded more than $27 million in grant funding to support major system improvements, regional partnerships and customer technology.

Your rates keeping pace Keeping up with rising costs guarantees dependable services To keep pace with rising costs, Western’s Board of Directors will consider a proposed rate adjustment that will affect your sewer rates for the next four years, effective with bills issued on or after July 1, 2021.

Western is a municipal water district governed by the laws of California, and we cannot and will not charge you more than what is necessary to provide service.

A cost-of-service analysis of Western’s current rates has indicated a need for increased rates to respond to the increasing costs of: • Collecting and treating wastewater (sewer). • Maintaining and operating the collection and treatment systems. Western is here for you every day, guaranteeing service 24 hours a day, 7 days a week, 365 days a year. We think about wastewater (sewer service) all day, so you don’t have to. This special notice will help you learn more about how Western is working hard to keep your toilets flushing and your rates as low as possible, now and in the future. You can view the cost-of-service study at wmwd.com/2021ProposedRates. The Western Riverside County Regional Wastewater Authority Treatment Plant is designed to treat up to 14 million gallons of wastewater (sewage) every day. The treated water is then used to irrigate parks and medians or is sent to the ocean.

The results of the study and proposed rate changes are in no way connected to the global COVID-19 pandemic.


PROPOSED SEWER RATES Your wastewater’s journey from your home through the sewers to a local treatment facility and back out into the environment is complex. Western has established several sewer service areas based upon the treatment facility and the collection system used to serve customers. The proposed rates are calculated to proportionately allocate the operations, maintenance and capital replacement costs of providing service to each customer class according to their sewer service area. Customers are billed a fixed amount each month.

Residential customers The rates for residential customers are based on an equivalent dwelling unit (EDU). One EDU is the quantity of wastewater an average single-family residential customer contributes to the sewer system. Each residential home is assigned one EDU.

Commercial customers Commercial customers are assigned EDUs based on their expected peak wastewater flows relative to an average single-family residential customer. Schools are assigned EDUs based on the number of students and a set number of gallons of wastewater discharged per student per day. Commercial, industrial and institutional EDU amounts can be found on the customer’s billing statement.

Current La Sierra Sewer Rate (Rate per EDU, per month) Residential/Commercial $50.40 Residential with Maintenance** $55.40

PROPOSED RATES Effective with sewer service billed on or after: 07/01/21 07/01/22 07/01/23 07/01/24 $51.91 $56.91

$53.47 $58.47

$55.07 $60.07

$56.72 $61.72

**Certain residential properties in Tracts 20782 and 28956 have private sewer pipelines that are maintained by Western pursuant to a written agreement with the original property developer. The $5.00 maintenance charge is an agreed upon term and is not subject to Proposition 218, and is reflected in this table for the convenience of the property owners.

Pass-through provision The proposed sewer rates and charges are based on current and estimated future rates and charges to be imposed on Western by our sewer treatment providers. If the actual rates and charges imposed on Western by our sewer treatment providers are higher than the estimated amounts, then Western is proposing to pass through to our customers the incremental difference by increasing the proposed rates of the sewer charge. Such increases, if any, will not exceed 12 percent per year, and in no event will such rates be increased by more than the cost of providing sewer service.
