Water Loss Opportunity Calculator
The infrastructure and financial case for water loss reduction — dollar-denominated exposure, peer context, and prioritized remediation paths.
Water loss is at or below the 10% TWDB planning standard. This utility is operating in maintenance mode with the financial value of sustained performance shown below.

Water Loss % vs. Anonymized Peers
Peers matched by size band (47,916 connections) and customer class mix (79% SF / 15% MF / 6% ICI).
Panel 3 · Top 3 Recommendations to Sustain Leadership
AWWA G500 / G480 Best-Practice Certification
Pursue formal AWWA water-loss management certification. Documents the utility's leadership position, supports rate-case arguments, and creates a sustained-performance baseline.
Peer-Utility Mentoring Program
Share methodology and lessons learned with peer Texas utilities through TWDB regional convenings. Strengthens statewide outcomes and positions the utility as a regional resource.
Continuous DMA Optimization
Ongoing refinement of existing DMA boundaries, night-flow analysis, and economic level of leakage (ELL) modeling. Maintains low loss as system ages.

Methodology
Performance tiers: Utilities are classified as Healthy (≤10% water loss, at or below the TWDB planning standard), Opportunity (10–15%, infrastructure case warranted), or Critical (>15%, significant exposure). Tier drives panel framing, projection scenarios, and which remediation interventions are surfaced.
Real / Apparent loss split: Demo uses the AWWA M36 industry default of 70% real / 30% apparent. Production deploys the actual ratio from each utility's annual TCEQ-required Water Loss Audit (TWDB-1721 form), and the ratio is editable by utility staff during the interview module if their own audit data indicates a different split.
10-year trajectory projection: Uses the compound annual growth rate of water loss GPCD across the utility's available history. Cost inflation applied at 3.5% per year (BLS water/sewer CPI 10-year average).
10-year “no intervention” / “slip” projection: For Opportunity and Critical tier utilities, models current loss volume held flat for 10 years (the “do nothing” worst case). For Healthy tier utilities, models a gradual ramp toward the regional-average loss rate (12%) over 10 years — representing the financial value of continued discipline.
Remediation recommendations: Selected from a tier-aware library. Opportunity / Critical utilities see foundational interventions (AMI deployment, DMA programs, acoustic leak detection, pressure management, main replacement). Healthy utilities see advanced sustainment interventions (continuous DMA optimization, AWWA G500/G480 certification, predictive failure modeling, peer-utility mentoring). Interventions already mastered are filtered out (e.g., AMI recommendations are suppressed for utilities at 95%+ existing AMI coverage). Production deploys the full Goldwater Recommendation Engine (Phase 3) with scenario modeling.
Peer comparison: Same peer-matching logic as Tool 1 — size band ±1 and single-family ratio within ±15 points. Peer water loss percentages shown anonymized: low, median, top quartile. No utility names disclosed.
