The system would continue to be owned and operated by Grand Prairie and Mansfield would pay a monthly charge to Grand Prairie for the transport of the Mansfield wastewater to the Trinity River Authority Regional Wastewater Plant (in addition to their share of the capital cost cited above) OR we could dedicate the system to the TRA where they would own, operate and maintain the system and each entity would pay to TRA their share of the operating costs.
TRA inspected the facility upon completion and requires a number of modifications/improvements that are conditional to their acceptance. The modifications are expected to cost in the range of $434,712.00 plus engineering costs .
