(a) WSSC will comprehensively review a request from an owner of an on-site water and/or sewer system that the Commission acquire all or parts of the system, that is, assume responsibility for future operation and maintenance of the system. If WSSC agrees to the acquisition request, the applicant must upgrade the system to WSSC standards before WSSC will formally take over the system. The applicant is also required to evaluate the system and complete all necessary system upgrades, and to reimburse WSSC for its costs to review the applicant’s evaluation and upgrade of the system. For on-site residential systems WSSC will, if requested by the owner, evaluate and upgrade the system. Such applicants are required to pay for WSSC’s system evaluation and upgrade costs; however, they may do so over a number of years, by agreeing to an annual property assessment.

(b) WSSC may also request that an owner of an on-site system allow WSSC to acquire all or part of the system. In such cases, the WSSC will evaluate and upgrade the system and pay all attendant costs. (PD 98-01 § III)
