Leak Detection on Mains

Water-distribution mains lose water continuously through joint failures, corrosion holes and tapping defects. Acoustic correlation, hydrophone surveys and noise loggers — the techniques described under our acoustic services — apply at network scale to find these leaks. We deliver utility-scale main-leak detection for municipalities, water districts, large institutional estates and industrial facilities, with deliverables that integrate into utility GIS and asset-management programs.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
