Water and Sewer Rates
We determine our water and sewer rates with cost of service, fairness and our financial stability in mind.
Like most water and sewer utilities, WSSC Water is a separate, government enterprise intended to be self-supporting. The majority of our revenue is derived from user charges - charges for services provided to customers. These charges may include fees, rates, assessments and billing; the charges are determined through a detailed process of allocating the cost of providing the services to the beneficiaries of the services.
WSSC Water takes great care to ensure that our rates are determined with equity, cost of service, fairness and our financial stability in mind. Our rate structure includes both variable and rates and includes the cost of maintaining and repairing our buried pipes and our treatment plants, as well as covering the cost of operations to ensure quality service is delivered to you every day.
