The District follows a July through June fiscal year and annually prepares a two-year operational plan and budget for approval by the District Board of Directors. Budget expenses include staff labor costs, capital improvement, supplies, and equipment, utilities service vendors, engineering consulting contracts, and charges paid to the City of San Diego for treatment and disposal of wastewater collection from District customers. The majority of the Revenue used to fund District expenditures comes from annual sewer service charges collected from District customers on property tax bills.
Each year, the District’s largest expense is the cost of treatment and disposal by the City of San Diego’s Point Loma Treatment Plant, also known as METRO. Metro treatment costs are typically 55-60% of the District’s annual operating budget. The next largest expense, typically 25-30% of the budget, is the cost of labor which is provided by staff of the County Department of Public Works, Wastewater Management section.
