For Engineers & Professional Engineers
Engineering Reference
Acoustic methodology, sensor BOM, NRW measurement per IWA/AWWA M36, GCTS-1 standard. No lore. No speculation. 0 sensors deployed — all hardware specifications are PROPOSED pending pilot procurement.
Acoustic Detection Methodology
Industry-standard acoustic leak-correlation approach — final sensor spec pending pilot procurement.
● VERIFIED — Industry standard
IWA/AWWA M36 Framework
Water balance methodology per IWA/AWWA M36 Water Audits and Loss Control Programs, 4th Edition. District Metered Area (DMA) approach for isolating leak zones.
This is the global standard for non-revenue water (NRW) quantification and is independently verifiable.
● PROPOSED — Pending procurement
Acoustic Correlation Sensor Approach
The proposed detection method uses acoustic leak correlation — an industry-standard technique for plastic and metal pipe networks. Specific sensor hardware, frequency range, and mounting protocol pending pilot procurement and third-party specification review.
Hardware Specification (Proposed BOM)
All hardware specifications use commercially available components. No custom ASICs. No proprietary chipsets.
NRW Projection
Non-revenue water reduction projection based on published methodology. Not a measured outcome.
● MODELED
12–28% NRW Reduction Range
Derived from IWA/AWWA M36 district metered area methodology applied to published Ogallala Aquifer region baseline conditions. Assumes 15–30% baseline NRW in aging US municipal systems (AWWA SOWI 2024).
Actual reduction quantified post-pilot instrumentation. Pilot data collection protocol defined in GCTS-1.
Verification: Current & Proposed
● VERIFIED — Current verification
SHA-256 Append-Only Logging
Data integrity via SHA-256 chained append-only logs. Compatible with IWA/AWWA water audit trail requirements.
Quarterly third-party audit of log integrity. No live telemetry pipeline exists — audit applies to proposal documentation.
● PROPOSED — Under development
ZK Verification Layer (not production-ready)
Rust Bulletproofs zero-knowledge proof layer under development. Intended to provide cryptographic proof of sensor readings without exposing raw data.
Status: Proposed ZK verification layer — not production-ready. Development stage. Current verification = SHA-256 append-only logs + quarterly third-party audit.
