What this plan covers
Original editable baseline for ordinary building stormwater pipework, pits, inlets and approved discharge connections. Covers approved hydraulic design boundaries, products, trench support, measured pipe profile, pit outlet levels, joints/separation, pre-cover records, specified functional checks and outlet handover. Excludes roof-gutter fabrication, public stormwater network construction, flood modelling/design, pumps/tanks and specialist civil stormwater treatment unless separately scoped. Hydraulic criteria, pit/outfall levels and discharge approvals must come from approved design, contract and local authority.
