Building Stormwater Drainage Inspection Record

Use this record for

Ordinary building surface/subsurface stormwater drainage within the project boundary, including identified lines, pits, inlets, connections and approved outlet interface.

Outside this record: Stormwater network design or sizing, universal levels/gradients/test requirements, public authority mains, major civil flood systems and on-site detention design; industrial/process, sanitary, gas or fire networks unless separately scoped and sourced.

Stormwater requirements and authority interfaces vary by jurisdiction and project. No default test is assumed: perform and record a test only where the approved project or authority documents require one. Capture actual surveyed levels with datum and the designated discharge destination.

Collect these project inputs first

Approved stormwater plans, pit schedules and outlet details: Define design nodes, levels, pits, flow route, destination and current revision.
Project survey/setout criteria and level datum: Allows actual levels to be recorded and compared on the correct datum and against stated tolerances.
Authority, consent and point-of-connection documents: Define approved network interface or on-site discharge arrangement where applicable.
Project test/inspection and pre-cover schedule: States whether functional testing, notice, witness or release is required; no generic requirement is assumed.
As-built and defect-closeout process: Defines required survey file, markup, photographs, repair records and handover evidence.

How to use the checklist

Use the approved drainage drawing to identify line, pit, inlet, connection and terminal outlet. Keep design and actual surveyed data distinct.
Record actual levels with unit and datum, linked to the survey/setout evidence and project acceptance source.
Inspect pit/access and pipe interfaces while visible; record exact connection identity and check separation from sanitary drainage.
Confirm and record the designated connection or approved disposal point from project/authority evidence.
Record a test only where required. Link method and source; if none is specified, state the basis for N/A.
Before cover or surface closure, link required inspection, photos, survey and as-built records and project-assigned disposition.

Checks and the records they need

Fill project criteria from approved documents before inspection. The fields below show what the downloaded form asks you to record; the web page does not save or approve site results.

Stormwater segment, pit and outlet log for repeat entries

Use one line per identified segment, pit, inspection or project-required test event. Record design and measured levels with their datum/source. A test is conditional on actual project/authority requirements; leave entries blank until observed.

SW-BED · Exposed trench, bedding and pipe support

Record trench condition, installed bedding and pipe support before they are concealed, where below-ground work is included.

How to check: Compare exposed work with the approved trench, bedding and embedment detail and relevant product instructions. Identify unstable formation, voids, debris, pipe movement and civil-work interfaces for project disposition.
What defines acceptance: Observed trench support, bedding and embedment correspond to the approved project detail. Material, thickness, cover and compaction requirements come from the actual applicable sources; this record supplies no default value.
Project document to cite: Enter approved drawing/detail and revision, applicable civil or geotechnical specification, and product installation instruction.

If a discrepancy is found: Keep the affected location identifiable, document the discrepancy and obtain the project-assigned disposition and reinspection before covering.

When a check cannot be closed

Situation	What to record or resolve
Outlet destination or approval is unclear	Trace the actual terminal line and obtain the project/authority record defining the permitted connection or disposal point.
Design and measured levels differ or use unclear datums	Preserve measured values and survey source; request written review against the project design and datum.
Stormwater/sanitary interface is uncertain	Record both line identities and actual connection evidence; request project direction before closing the issue.
No test requirement is found	Record the documents checked and request confirmation if the project scope remains ambiguous; do not invent a test.
Pre-cover or as-built evidence is missing	Identify affected extent and obtain required survey, inspection, markup or disposition before handover.
