Stately covers Auckland CBD. We need to check where the waste can connect and how excavation fits around the tenancy, rather than choose a drain position from a photograph.
Define what will enter the floor waste
Tell us whether the floor waste is for washdown, incidental spills or another purpose. Mark nearby sinks, equipment, counters and doorways on the drawing. Describe cleaning products and anything else expected to enter it. The intended discharge helps the designer assess the drainage arrangement and any treatment requirements.
Confirm the designer’s and Watercare’s requirements for commercial discharge before pipework is settled. Give us the landlord’s fitout conditions and name the person authorised to approve changes. Keep the café operator involved so the proposed grate position remains accessible for cleaning after benches and equipment are installed.
Locate the connection before opening the floor
Send available drainage plans and previous alteration records. Onsite, we check accessible drainage points, the proposed route and connection levels. We also establish which spaces need access. A pipe shown nearby on a drawing still needs its position and suitability checked before the excavation route is agreed.
Owners maintain private pipes. Watercare manages public wastewater, while Auckland Council manages public stormwater. Establishing the relevant asset matters before connecting or excavating. Building or excavation near public wastewater pipes may require Watercare approval. Keep any required approvals in the fitout programme rather than treating them as handover paperwork.
More about drainlayer in Auckland CBD
Coordinate the trench with the fitout team
Agree the excavation footprint with the builder after locating services and checking the floor construction. Structural details need the appropriate designer’s input. Set out the floor waste against the finished floor level, not just the exposed slab. This keeps the drainage position coordinated with flooring, waterproofing and equipment clearances.
Confirm the work’s consent requirements using MBIE guidance and the actual proposed scope. Restricted drainlaying requires an appropriately authorised person, whose authorisation can be checked through the PGDB register. Arrange access, spoil removal and protection of adjoining areas before opening the trench. Identify when the café must stop using affected drainage.
Lay the branch and reserve inspection time
Once the route is exposed, we check the receiving pipe’s condition and levels against the planned connection. The work can then include laying the new branch, installing the floor waste assembly and repairing the connection area where required. Pipe selection, falls, trapping and access follow the confirmed design and onsite findings.
Leave the relevant pipework exposed for testing and required inspection. Book these stages before the builder schedules backfilling or floor closure. Any new wastewater connection follows Watercare’s application, inspection and completion process. Record changes found during excavation and obtain the necessary design decisions before concealing a revised route.
Close the floor with a usable record
After testing and inspection are complete, coordinate backfilling and the agreed surface reinstatement. State who handles the slab repair, waterproofing and final floor finish. Handover should distinguish completed drainage work from remaining fitout work, with the grate accessible and the surrounding work area cleared of excavation debris.
Provide the owner and builder with photographs taken before covering, the installed route, connection location and relevant test and inspection records. Include approved changes and completion documents where applicable. Explain how to keep the grate clear and which access points must remain reachable when equipment is moved into place.
Drainlayer: questions from Auckland CBD
Can we position the waste beneath a counter?
Send the counter layout first. We check access for cleaning, the floor arrangement and the proposed pipe route onsite. The designer confirms the arrangement before the builder fixes the counter position.
Can the café stay open during excavation?
Plan this with the operator and builder. Identify affected drainage, the work boundary and access for spoil removal. Agree when connected fixtures must stop being used before the trench is opened.
When should the flooring contractor return?
Programme final flooring after drainage testing, required inspections and the agreed floor repairs. Share the finished grate level and waterproofing details with the builder so the floor junction is coordinated before closure.
