Septic tank installation and replacement, rainwater tank connections and pressure pump systems for rural and lifestyle properties across Hamilton and the Waikato — by PGDB-licensed plumbers and drainlayers.
Step outside Hamilton’s city boundary and most properties run on their own water and wastewater: rainwater tanks and pressure pumps for supply, septic tanks and drainage fields for waste. The lifestyle blocks and farms around Cambridge, Te Awamutu, Huntly, Taupiri and Te Kauwhata all depend on these systems working properly — and on someone qualified to install and maintain them.
Plumbway Ltd is registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB) as both plumber and drainlayer, which is exactly the combination tank work needs. The drainlaying licence covers septic tanks and drainage fields; the plumbing licence covers the supply side — tank connections, pressure pumps and filtration. One team handles the whole system.
We work on these systems every week as part of our rural coverage across the Waikato region — see also our Waikato drainlaying page for the drainage side of rural properties.
Septic systems in the Waikato sit under two layers of rules: your district council’s building consent process, and Waikato Regional Council’s requirements for on-site wastewater discharge. Get either wrong and you can end up with a system the council won’t sign off — or one that fails early because the drainage field wasn’t matched to the soil.
Because we install these systems under all four Waikato district councils, we know what each expects — tank sizing, drainage field design, setback distances and the inspection sequence. We manage the consent process from application through to final sign-off, so your system is legal, insurable and built to last.
Yes. As PGDB-registered drainlayers we install new septic tanks and replace failed or undersized ones on rural and lifestyle properties across the Waikato — including the tank itself, the drainage field and all connecting pipework, with the council consents the work requires.
Common signs are wastewater surfacing over the drainage field, persistent odours, slow-draining fixtures throughout the house, or a tank that needs pumping out far more often than it used to. Tanks and drainage fields have finite lifespans — many older Waikato systems are past theirs. We can inspect the system and tell you whether repair, a new drainage field or full replacement makes sense.
Yes. Many rural properties around Hamilton, Cambridge, Huntly and Te Awamutu run on rainwater rather than town supply. We install and connect rainwater tanks, pressure pumps and filtration so the house has reliable, clean water — and we service and replace failed tank pumps.
New and replacement septic systems need consent — on-site wastewater is regulated by the district council and Waikato Regional Council rules. Rainwater tank installations can also need consent depending on size and siting. We advise what applies to your property and handle the paperwork as part of the job.
Hamilton and the surrounding rural country, plus the wider Waikato — Cambridge, Te Awamutu, Huntly, Ngaruawahia, Te Kauwhata, Morrinsville, Matamata and Raglan. Lifestyle blocks and farms on the edges of these towns make up a large share of our tank and septic work.
