Approved Fiscal Year 2021/2022 Sewer Service Charges

Delta Diablo approved SSC adjustments, effective July 1, 2021

Delta Diablo provides wastewater conveyance and treatment services for over 70,000 customer accounts (residential and non-residential), representing approximately 214,000 residents in Antioch, Pittsburg, and Bay Point. In developing our budget each year, we carefully consider operational and capital investment needs to maintain effective and reliable wastewater conveyance and treatment services.  

Our primary revenue source comes from Sewer Service Charges (SSCs) charged to residential, commercial, and industrial customers on the tax roll each year. For Fiscal Year 2021/2022 (beginning on July 1, 2021), Delta Diablo approved SSC increases for residential customers by $26.32/year (6.5%, $429.42 total) for Antioch/Pittsburg and $32.78/year (5.9%, $589.25 total) for Bay Point and various adjustments for non-residential customers as shown in the Fiscal Year 2021/2022 SSC Proposition 218 Notice. The District has worked hard to reduce the impact of SSC increases on the local community, especially in consideration of the ongoing COVID-19 pandemic. The SSC adjustments are required to prioritize sustained capital investment to maintain the integrity of our aging infrastructure, while ensuring sufficient funding to meet progressive increases in operating costs and associated regulatory compliance obligations. We endeavor to meet these challenges while ensuring SSCs remain among the lowest when compared to our peer agencies in the Bay Area region. 

Delta Diablo is committed to fair and reasonable rates. As a not-for-profit public agency, state law only allows the District to recover costs necessary to operate and maintain our system and ensure that it is stable and safe to achieve our core mission of protecting public health and the environment. Periodically, adjustments to SSCs are required for both residential and non-residential customers to rebalance cost allocation between these customer categories based on cost-of-service. The District follows Proposition 218 guidelines for establishing rates and conducting public hearings. The District has been recognized for excellence in financial reporting by the Government Finance Officers Association and is audited annually by an independent accounting firm. As an industry leader, the District values strong community engagement, serving as responsible stewards of the public’s resources and trust, transparency, innovative approaches, and sustainable solutions in achieving its core mission of protecting public health and the environment. 

For more information, Delta Diablo has developed two fact sheets to describe key drivers for the SSC adjustments and infrastructure investment through our capital improvement program. In addition, we have prepared a “Frequently Asked Questions” (FAQs) document to highlight additional information for our customers. A link to the Proposition 218 Notice that was mailed to all property owners by April 23, 2021 is also provided below.
