The Coastal Water Authority (CWA) entered into a contract (the “Initial Contract”) with the City of Houston (the “City”) in May 1968. The contract expires on the earlier date of June 15, 2035 or the date on which the debt service requirements have been paid in full. In consideration of CWA’s agreement to construct the main water conveyance and distribution systems, the City agreed to pay, solely out of revenues received from the operation of the City’s water and wastewater systems, all maintenance and operating costs and all debt service requirements for the Trinity River Water Conveyance System. Upon termination of the contract and upon payment of all bonds and other obligations issued by CWA for the Trinity River Water Conveyance System, CWA must assign and convey to the City, upon request, all of its rights, titles, and interest in the Trinity River Water Conveyance System.

In June 1995, CWA entered into an operating contract (the “Operating Contract”) and a project financing and construction contract (the “Projects Contract”) with the City. The Operating Contract amends, restates, and supersedes the Initial Contract relating to CWA’s operation for the Trinity River Water Conveyance System. In the Operating Contract, CWA is required to operate and maintain the Trinity River Water Conveyance System and the facilities constructed and/or acquired (“Trinity River facilities”) pursuant to the Projects Contract and acquire and/or construct improvements to such facilities or other City facilities. In return, the City pays CWA for maintenance, operation, construction, improvement, and repair of the City projects, including reasonable overhead and administrative costs, as set forth in the annual operating budget. The City is entitled to credits against its obligations under the Operating Contract to the extent that excess revenues, including proceeds from third-party insurers and grants from any Federal or state agency, received by CWA from the operation of the Trinity River facilities are available and are used to pay maintenance, operation, construction, improvement, and repair expenses of the facilities pursuant to the terms of the Operating Contract.
