The DC Water and Sewer Authority Billing and Disconnection Clarification Temporary Amendment Act of 2026 aims to enhance the oversight and regulation of the District of Columbia Water and Sewer Authority (DCWSA). The bill amends the Language Access Act of 2004 to include the DCWSA as a covered entity with major public contact. It also requires the DCWSA to submit monthly reports to various governmental offices regarding disconnections due to non-payment. Additionally, the bill clarifies the imposition of charges and penalties for late payments and modifies the notice requirements for water service disconnections to ensure better communication with building occupants.

Key amendments include the addition of a new sub-subparagraph to the Language Access Act, specifying the DCWSA's inclusion, and changes to the Water and Sewer Authority Establishment Act that detail the penalties for late payments. The bill also revises the notice requirements for disconnections, ensuring that occupants receive timely and clear information about their water service status. The act is set to take effect following approval by the Mayor and a congressional review period, with a temporary expiration after 225 days.
