Sewer Service Charges
Delta Diablo Board of Directors approved SSC adjustments at a public hearing on June 22, 2022.
Delta Diablo provides wastewater conveyance and treatment services for over 71,000 customer accounts (residential and non-residential), representing approximately 215,000 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 2022/2023 (beginning on July 1, 2022), Delta Diablo approved SSC increases for residential customers by $19.33/year (4.5%, $448.75 total) for Antioch/Pittsburg and $26.52/year (4.5%, $615.77 total) for Bay Point and a uniform 4.5% increase for non-residential customers. The District has worked hard to control costs and reduce the impact of SSC increases on the local community. The proposed SSC increases 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 are below the average of 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 for the future. 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 (completed in 2021). 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 and progressive “Utility of the Future”, the District values community engagement, serving as responsible stewards of the public’s resources and trust, transparency, innovation, and workforce engagement and development to achieve 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 proposed SSC increases 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.
