Acoustic Leak Correlation

Cross-correlation is the gold standard for locating leaks on pressurized water mains. Two synchronized sensors at known points on a line pick up the leak signature; the correlator computes the time delay between them and resolves the leak position to within a metre or two on a buried main. We operate correlators across copper, ductile iron, cast iron, PVC and HDPE mains for municipalities, utilities, industrial facilities and large commercial properties. Each survey is delivered with the raw correlation data, sensor placement, and a clear locate mark on site.

Pairs well with

Clients booking acoustic leak correlation often combine it with Ground Microphone Surveys or Hydrophone Inspections — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

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).
