The Town of Discovery Bay Community Services District (“Town”) provides water supply, treatment, and delivery as well as wastewater collection, treatment, and disposal to approximately 14,000 residents. The Town recently completed master plans that determined the level of growth for the community through FY2021 and identified needed facility improvements. Some improvements are needed to correct deficiencies in existing facilities and other improvements are needed to expand capacity to serve future development. In addition, the Town has received guidance from the Regional Water Quality Board (“Regional Board”) that the Town’s wastewater treatment plant must add effluent filtration by 2019 and denitrifying facilities by 2024 in order to meet regulatory requirements.
This Technical Memorandum was developed with the goal of fairly assigning the cost of improvements to existing and future customers and to calculate capacity fees that recover these costs.
