Storm, Sanitary & Drainage Leak Investigation in British Columbia
Storm and sanitary drainage failures don't announce themselves with a pressurized spray — they exfiltrate, undermine, and surface far from the break. For commercial sites, stratas and municipalities, investigating buried storm, sanitary and site-drainage systems requires camera, tracing and hydrostatic methods to find the failure.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Drainage leak investigation locates breaks, cracks, blockages, root intrusion, displaced joints and exfiltration in storm sewers, sanitary lines, catch basins and site drainage using CCTV camera inspection, sonde locating, dye and hydrostatic testing. Because these systems carry no pressure in normal use, the methods differ from supply-line detection — and the findings inform repair, capital planning and the asset record.
- Cracked, broken or displaced storm and sanitary lines
- Root intrusion and blockages in buried drainage
- Exfiltration undermining slabs, roadways and foundations
- Catch-basin, area-drain and site-drainage failures
Why It Matters
Finds the true break, often far from where water surfaces
Identifies exfiltration before it undermines structures
Documents condition for repair, capital planning and asset records
Storm, Sanitary & Drainage Leak Investigation — FAQ
Drainage systems are investigated with CCTV camera inspection to see breaks, root intrusion and blockages directly, sonde locating to mark the defect, and dye or hydrostatic testing to confirm exfiltration. GPR can map voids where escaping water has washed out the soil.
Exfiltration is wastewater or stormwater escaping a cracked or broken buried line into the surrounding ground. It washes out soil and can undermine slabs, roads and foundations, so locating and documenting it is important for both repair and structural protection.
