The Tarrant Regional Water District Integrated Water Supply Plan (IWSP) is an integration of the discrete planning that has been done over many years for new water management strategies (conservation, new reservoirs) with the greatest potential impact on water supply reliability. The plan is not fully comprehensive, but is rather a platform that will be constantly built upon by integrating new opportunities (e.g. local sources, reuse of treated wastewater effluent), technologies (e.g. aquifer storage and recovery, advanced conservation), and strategies (e.g. groundwater) with the plan presented here. The project included a description of the conclusions of the IWSP and the sequence employed to arrive at a final 50-year TRWD water supply planning decision tree, an adaptive management plan based on major triggers that result in selection and sequencing of strategies.
