Public Works Act of 1954]’s exception for ‘water and water services furnished to the United States for the . . . extension of the water system,’ does not apply to sewer services supplied by the District to the [Armed Services Retirement Home], because, in its view, [a] 1938 Agreement did not provide water and water services for the maintenance, operation, and extension of the water system.”
2. “Whether the District’s demand for payment for its ongoing provision of sewer services is barred by the doctrines of waiver and/or equitable estoppel, where the District abided by the 1938 Agreement for 50 years after the 1954 Act, and where the District had formally asserted that the 1938 Agreement protected the Home from any water or sewer charges, notwithstanding the 1954 Act.”
