We are currently in the midst of the largest upgrade to our wastewater
treatment plant since its inception. These upgrades—known as the EchoWater Project—must be completed and operational by 2023, and the construction cost alone is between $1.5 and $2.1 billion.
MAY 2019 UPDATE: In March 2017, our Board of Directors approved a five-year rate increase plan, which included incremental annual rate increases through Fiscal Year (FY) 2021, to help pay for the mandated EchoWater Project. Regional San worked diligently to implement various cost-saving measures, including controlling project costs and securing a low-interest loan to help fund the EchoWater Project. As a result, in May 2019, our Board rescinded previously approved rate increases for the last three years of the five-year rate increase plan (FY 2019, FY 2020, and FY 2021). That means rates will stay at current levels through June 30, 2022.
Rates for Residential and Commercial Customers

Rates for Industrial Customers
Per cost component
The table below represents the new industrial sewer rates, also charged to groundwater remediation dischargers and temporary discharge permit users. Unlike residential and commercial customers, who are charged on ESD units that represent an average flow and waste strength, industrial customers are charged based on their individual wastewater flow and waste characteristics (Biochemical Oxygen Demand—BOD; Total Suspended Solids—TSS; Total Kjeldahl Nitrogen—TKN; and pathogens).
|Cost Component||Rate and Effective Date|
|1 – Flow volume in millions of gallons
2 – Biochemical Oxygen Demand in thousands of pounds
3 – Total Suspended Solids in thousands of pounds
4 – Total Kjeldahl Nitrogen in thousands of pounds
5 – Pathogens in millions of gallons of domestic sewage
