Methodology

The Performance Index is a weighted composite of five dimensions calibrated against public Texas water-sector benchmarks.

Total GPCD efficiency (25%) — current GPCD scored against the utility's regional benchmark.
Residential GPCD efficiency (20%) — residential consumption per capita against Texas residential norms.
Water Loss GPCD (25%) — gallons-per-capita lost daily, scored against TWDB and AWWA best-practice thresholds.
Peak demand per capita (20%) — peak month gallons per capita per day. Drives infrastructure investment decisions.
Water loss as % of system input (10%) — ≤5% excellent, ≥20% poor.

Weights and thresholds are re-calibrated quarterly as the statewide Water Conservation Plan Annual Report cohort dataset grows. Peer cohorts match on size band + customer class mix.
