Water Supply, Drainage & Stormwater Systems in Langley BC
In the rain-soaked Lower Mainland, water management is everything. TDS Civil designs and installs drainage and stormwater systems that perform.
Failed drainage destroys foundations, parking lots and landscapes. TDS Civil installs complete water management systems — drywells, swales, foundation drains, catch basins and collection networks — engineered for the Fraser Valley’s heavy seasonal rainfall and high water tables. We work on new construction and retrofit failing systems on existing strata, commercial and residential properties.
For larger developments we build storm retention tanks and ponds, manage stormwater and sewer system installations, and maintain existing infrastructure with irrigation clean-outs and retention pond cleaning. Every system is built to municipal standards in Langley, Surrey, Abbotsford and across Metro Vancouver.

Frequently Asked Questions
How do I know if my foundation drainage has failed?
Warning signs include damp basement walls, pooling water near the foundation, efflorescence on concrete and musty smells. We perform camera inspections and excavate test pits to confirm drain tile condition before recommending repair or replacement.
What is a drywell and is it right for my Langley property?
A drywell is an underground structure that collects roof and surface runoff and disperses it into surrounding soil. It’s an effective solution where storm sewer connection isn’t practical — common on rural Langley and Abbotsford acreages. We assess soil percolation to size it correctly.
Do you install catch basins and connect to municipal storm systems?
Yes. We install catch basins, lawn basins and collection piping, and complete municipal storm sewer connections to City of Langley, Township of Langley, Surrey and other Lower Mainland standards.
Do you clean and maintain storm retention ponds?
We provide retention pond cleaning, sediment removal and outfall maintenance for strata and commercial properties — including environmentally sensitive pond work handled through our environmental services division.
Can you fix a flooded parking lot or yard?
Yes — we diagnose grading and drainage failures and fix them with regrading, swales, catch basins and new drainage lines, restoring proper flow and protecting your asphalt and landscaping.
