Job done and tidied
We finish the work and leave the site clean.
Send Stately a site plan, the proposed fixture positions and any available drainage drawings first. Stately covers Manurewa. The first onsite task is to check where the new drainage can connect and what levels that route allows.
Set out the bathroom before excavation
Mark the sleepout footprint, toilet position and basin location on the same drawing. Include finished floor information from the designer, foundation details and the proposed construction sequence. Photos should show the space between the sleepout and house, accessible drain openings, gates and surfaces along the possible trench route.
Explain whether the slab is still being designed, ready to pour or already built. That changes how drainage openings are coordinated with the builder. Have the designer confirm the consent requirements for the actual sleepout and drainage work using MBIE guidance. Settle the required drawings and inspection stages before booking excavation.
Confirm the receiving pipe and levels
An existing drainage drawing gives us a starting point, not a final connection position. Onsite, we locate the receiving wastewater pipe, establish its depth and check its condition at the proposed junction. We compare those findings with the sleepout outlet level before settling the pipe route with the designer.
The connection assessment also establishes whose pipe is involved. Owners maintain private pipes, while Watercare manages public wastewater pipes. A new connection to the public network follows Watercare's application, inspection and completion process. Building or digging near its assets may also require approval. Resolve those steps before the builder commits foundations beside the proposed trench.
More about drainlayer in Manurewa
Open a workable trench route
Once the route is settled, we mark the excavation and check other services crossing it. Discuss access for excavation, spoil storage and keeping a usable path between buildings. Identify paving, concrete and garden areas separately so the reinstatement scope describes what will actually be disturbed.
Excavation exposes the connection point and creates space for the specified pipe bedding and joints. We check the exposed pipe before cutting into it and agree any necessary repair to that section. Keep the builder informed of trench positions beside foundations. Agree when the existing wastewater pipe can be interrupted, rather than discovering that conflict during bathroom use.
Lay drainage around the building programme
We lay the underground wastewater pipework to the confirmed layout, with bedding, joints and access points suited to the approved details. The toilet and basin drainage positions are coordinated with the plumber and builder. Check offsets against the actual wall and floor setout before the slab closes over those locations.
Restricted drainlaying must be undertaken by an appropriately authorised person; check their authorisation through the PGDB register. Schedule the required drainage testing and inspections while the relevant work remains visible. The programme should allow findings to be addressed before covering pipes. Backfilling follows completion of those checks, with the pipe supported and protected as specified.
Hand over records and usable surfaces
Record the installed route, connection location and access points before the trench disappears. Handover should include the drainage layout, photographs, test information and inspection records relevant to the work. For a new public wastewater connection, include the completion documents required by Watercare.
Confirm which surfaces are reinstated under the drainage scope and which are handed back to the builder or another trade. Describe the finished condition of concrete, paving and planted areas separately. Keep drainage access points reachable. Walk the owner through their locations so later landscaping or storage around the sleepout leaves them available for maintenance.
Drainlayer: questions from Manurewa
Should we order the toilet first?
Send its installation details before ordering. The plumber and drainlayer need to coordinate the outlet with the floor setout and confirmed drainage route.
Can the sleepout join the house drain?
That needs an onsite check of the receiving pipe, levels and proposed connection. A nearby drain opening alone is not enough to settle the route.
When should the trench be covered?
After the required testing and inspections are complete and the installed route is recorded. Put that hold point in the builder's programme before excavation starts.
