Infiltration & Inflow Studies

Infiltration (groundwater entering through pipe defects) and inflow (stormwater entering through cross-connections) cost utilities millions in unnecessary treatment. Our I/I studies combine flow monitoring, smoke testing, dyed water testing and targeted CCTV to identify and quantify entry points across a service area. We deliver these for municipalities and large institutional properties with combined or aging sanitary systems.

Why Sewer Scans for infiltration & inflow studies

Sewer Scans is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.

We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Pairs well with

Clients booking infiltration & inflow studies often combine it with CCTV Sewer Inspection or Sewer Leak Detection — 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).
