Water Planning Roadmap

Build the optimized five-year plan to hit CORPUS CHRISTI's 184 GPCD goal by 2030 — with phased BMPs, infrastructure, supply strategies, and a TAC §288.2-compliant Water Conservation Plan ready to file.

Combined reservoir storage sits at 9.6% as of May 2026, with a Level 1 drought emergency projected for September 2026. The city's last Water Conservation Plan was filed September 4, 2020; its 2025 five-year target date has passed without a refresh.

Supply vs. Demand

How CORPUS CHRISTI's demand gets met each year, by source. Drought lowers available supply (blue); conservation and the planned projects fill the gap; red is what nothing covers yet.

How to read this: each stacked bar is how that year's demand (line) is met — existing supply (blue), roadmap conservation (green), and the State Water Plan's desalination & reuse strategies as they come online in 2030 (gray). Red is demand nothing covers yet. Green rising above the demand line is a conservation cushion — supply you don't have to build.

Supply covers demand

On the State Water Plan's firm-yield assumptions, existing supply meets demand. But the reservoirs are at 9.6% — raise the drought stage to see the operational gap that planning number hides.

Total GPCD vs Filed and Projected WCP Goals

Historical actuals against the city's 2020 WCP filed goals (solid) and the 2025 refresh cycle the city would have filed using its own 1% annual reduction methodology (dashed).

Last filed WCP: September 4, 2020. Per TAC §288.2, WCPs must be reviewed and updated every five years. Next refresh due 2025; not filed. Dashed projection applies the city's stated 1% annual reduction methodology to a 2025 baseline reflecting the observed trajectory (198 Total GPCD, water loss essentially flat at 7.3%).

Close the 14-GPCD gap to CORPUS CHRISTI's 2030 goal

Goldwater optimizes across the full best-management-practice library — ranking every measure by cost-effectiveness, respecting fixture saturation, freerider rates, decay, and useful life — to build the lowest-cost path from 198 to 184 GPCD.
