Stormwater Pond & Outfall Leak Survey in Mission, BC

Detention ponds, retention facilities, outfalls, and culverts surveyed for exfiltration, berm seepage, and bypass flow — the drainage infrastructure nobody can see failing until something downstream floods or erodes. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving Mission and the Fraser Valley region — since 1999 as BC's leak detection specialists.

Flying Mission: local context

Hillside homes and floodplain industry — terrain that makes ground access slow is exactly where aerial wins.

Local property profile: Hillside homes with long gravity-fed service runs, heritage downtown, and floodplain industry.

Ground conditions: Hillside till scans well between rock outcrops; the floodplain industrial flats are wetter. Slope properties put services shallow and traceable.

Typical stormwater pond & outfall leak survey work around Mission

  • Hillside roof surveys
  • Industrial flat inspections
  • Municipal detention and retention ponds
  • Development stormwater facilities at turnover
  • Outfall and culvert condition screening

How the Mission survey runs

  1. 1

    Facility review

    Design drawings establish what the pond is supposed to do — normal water level, outlet structure behaviour, berm geometry. Deviations from design are what the survey hunts.

  2. 2

    Aerial mapping flight

    Thermal plus high-resolution visual covers the pond, berms, inlet and outlet works, and the downstream path. Water level, wetted perimeter, and berm condition are captured in one georeferenced dataset.

  3. 3

    Anomaly analysis

    Seepage expression on berm faces, thermally distinct inflows that should not exist, scour at outfalls, and saturated zones beyond the design footprint are flagged and ranked.

  4. 4

    Condition report

    A facility plan with annotated findings — formatted for public-works files, development acceptance packages, or the consultant's stormwater management review.

Mission questions, answered

What goes wrong with stormwater ponds that this finds?

The common failures are quiet ones: berms seeping through rodent burrows or poorly compacted lifts, liners leaking so the pond never holds design volume, outlets short-circuiting, and exfiltration saturating ground beyond the facility. All express thermally or visually at the surface — and all are far cheaper to fix before a major storm finds them first.

Why survey a developer-built pond before municipal acceptance?

Because once a municipality accepts the facility, its defects become the public's. An aerial condition survey at turnover documents berm condition, water behaviour, and any seepage objectively — either confirming the asset is sound or putting deficiencies on the record while the developer still owns them.

Can you inspect outfalls and culverts too?

The approaches, headwalls, scour patterns, and surrounding ground — yes, and that screening tells you which structures justify CCTV or confined-space entry. We pair naturally with our ground-based CCTV inspection service for the inside-the-pipe half.

Can you legally fly drone leak surveys in Mission?

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Mission flights run under whatever airspace authorizations the location requires. Hillside homes and floodplain industry — terrain that makes ground access slow is exactly where aerial wins. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

How do Mission ground conditions affect what the survey reads?

Mission ground is predominantly steep till and bedrock benches above Fraser floodplain. Hillside till scans well between rock outcrops; the floodplain industrial flats are wetter. Slope properties put services shallow and traceable. For buried-leak work that matters: escaping water changes the moisture and thermal behaviour of exactly that ground, and our analysts interpret the surface signal against the local soil character — then our acoustic ground crews confirm the suspect zones before anyone digs.

What does stormwater pond & outfall leak survey cost in Mission?

Province-wide pricing — no regional premium for Mission. Single-site surveys typically start in the high hundreds; network corridors, portfolios, and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
