Job done and tidied
We finish the work and leave the site clean.
Send photographs of the proposed channel position, nearby drainage access points and the driveway surface, plus any drainage plans. Stately covers Botany Downs. Onsite checks establish the levels, receiving pipe and excavation route before the connection work is agreed. A grate alone cannot solve a missing or unsuitable outlet.
Show the driveway and the intended collection line
Include a wide photograph showing the driveway, garage entrance and nearby paving. Mark where water collects during rain and describe its route using observations you already have. Send the channel product details if one has been selected. Its outlet position and installation instructions matter when coordinating pipework and concrete.
Tell us whether this is an existing driveway or part of a planned pour. Share the builder's programme, vehicle access needs and proposed finished levels. Keep channel selection open until onsite levels and anticipated vehicle loading have been checked. This avoids setting a channel that cannot connect at the required level.
Confirm the receiving drain before excavation
We compare available plans with accessible drainage points and locate the proposed receiving pipe onsite. The checks cover its purpose, condition, depth and relationship to the channel outlet. Stormwater needs an appropriate stormwater discharge route, rather than a convenient pipe chosen because it happens to cross the driveway.
Owners maintain private pipes. Watercare manages public wastewater, while Auckland Council manages public stormwater. Confirm ownership at the proposed connection. Use MBIE guidance to establish consent requirements for the actual work. Excavation near Watercare assets may require approval. Settle the required permissions before booking the driveway pour.

Open a defined route and connect the pipework
Agree the trench route, concrete cuts and access arrangements before digging. Locate other services along that route and expose connection points carefully. Excavation must provide room for bedding, pipe joints and inspection, while protecting adjacent paving. Keep excavated material and equipment clear of the channel line and working access.
Lay the connecting pipe on prepared bedding at the checked levels. Fit the channel outlet and appropriate junction into the confirmed receiving drain. Repair damaged private pipe encountered within the agreed scope before joining new work to it. Restricted drainlaying requires an appropriately authorised person; check authorisation through the PGDB register.
Coordinate channel support, testing and inspection
Coordinate the channel's support and surrounding concrete with the builder and manufacturer instructions. Check grate height against the finished driveway so water can enter the channel. Confirm the grate can be removed for cleaning. Protect the open channel from concrete slurry and construction debris during the remaining driveway work.
Leave relevant pipework exposed for testing and required inspection before backfilling. Check joints, levels and discharge through the completed connection. A controlled water test also checks entry into the channel and reveals local ponding. Agree inspection stages early so concrete placement follows the checks rather than concealing work awaiting inspection.
Record the connection and finish the driveway
At handover, provide photographs of the exposed connection, its recorded route and relevant inspection or completion records. Identify the receiving drain and accessible cleaning points. Explain how to lift the grate safely and remove sediment from the channel. Keep these details with the property's drainage plans for future driveway work.
Confirm the agreed reinstatement boundary before excavation starts. After testing and inspection, backfill and compact the trench, then complete the agreed surface finish. Record any remaining concrete or paving work assigned to the builder. Explain when the reinstated area can take vehicles using the applicable material instructions.
Drainlayer: questions from Botany Downs
Can we connect an existing channel?
Yes, after checking its outlet, support, condition and levels onsite. The receiving drain and connecting route also need checking before retaining the channel.
Should the driveway be poured first?
Coordinate the connection beforehand. Pipe levels, channel support, testing and inspection need programme space before concrete conceals the work.
Will a deeper channel fix standing water?
Depth alone is not the deciding factor. Check driveway levels, grate position and the outlet route onsite before choosing a replacement channel.
