Licensed Drainlaying for Mt Roskill Infill Housing & Renovations
PGDB certified drainlaying contractors specializing in Mount Roskill's intensive multi-unit terrace developments and residential renewals. We install complete underground services, upgrade public sewer laterals, and provide rapid Producer Statement PS3 sign-offs for Auckland Council CCC.
Auckland Council PS3 Sign-Offs
We manage the entire council compliance sequence: site inspection, low-pressure air testing, As-Built CAD plans, and formal Producer Statement PS3 sign-offs to ensure your Code Compliance Certificate (CCC) is approved without delays.
Multi-Unit Terrace Housing Infill
Under Auckland Unitary Plan Mixed Housing Urban zoning across Mount Roskill, we install shared private drainage, common boundary collection chambers, and precision laser-guided sewer lines for 2 to 8-unit developments.
Public Main Upgrades & Ties-Ins
Increased residential density demands increased sanitary capacity. We handle Watercare live connection permits, public sewer lateral upgrades, and precast concrete manhole tie-ins along Dominion and Richardson Roads.
Drainlaying for Multi-Unit Townhouses & Subdivision Developments in Mount Roskill
Mount Roskill has seen extensive urban intensification under the Auckland Unitary Plan, replacing single-dwelling sections with modern terrace townhouses. Installing underground services on tight, multi-unit sites requires strict adherence to legal falls, boundary clearances, and council-approved drainage layouts.
Craft Civil Contractors installs complete residential drainage networks—from primary 100mm/150mm sanitary sewer laterals laid at certified 1:60 gradients to shared stormwater collector lines, downpipe connections, and driveway channel grates. We work closely with builders, project managers, and council inspectors to keep your development on schedule and fully compliant with our certified Auckland drainlaying services.
Public Sewer Upgrades & Watercare Live Connections in Mt Roskill
Subdividing an existing site in Mount Roskill frequently requires upgrading older 100mm earthenware connection branches to 150mm heavy-wall Class SN8 PVC-U to accommodate the additional discharge from multiple new dwellings.
Our certifying drainlayers manage Watercare connection applications, site boundary inspections, and live sewer main tapping under approved utility guidelines. Where public lines cross private boundaries, we ensure compliance with Watercare Works Over rules, constructing concrete encasements and protective bridge structures where required. Learn more about our Watercare public drainage infrastructure capability.
Stormwater Detention Tanks & On-Site Mitigation for Mt Roskill Sections
With increased building footprints and paved driveways, Mount Roskill building consents strictly regulate stormwater discharge to protect local public stormwater networks from flash flooding during heavy rain.
We excavate, pour reinforced concrete base pads, and install above-ground slimline and underground stormwater detention tanks fitted with precision orifice restrictor plates. These systems slowly release stormwater at a controlled rate into council mains. Explore our stormwater detention and rainwater tank installation options.
Frequently Asked Questions — Mt Roskill Drainage
How fast can Craft Civil issue a Producer Statement PS3 for a Mount Roskill project?
Immediately upon completing the pipe installation and passing mandatory low-pressure air or water testing, our certifying drainlayer completes the As-Built drainage plan and signs the PS3 document for submission to Auckland Council.

Yes. We handle the complete package: site excavation, tank base concrete pours, tank placement, orifice plate installation, and connecting all downpipes and overflow lines into the legal point of discharge.
