Discount Drainage is a locally owned drainlaying company based in Sydenham, Christchurch. We install and repair drainage for homes, new builds, subdivisions, multi-unit developments and light commercial sites, using our own crews and machinery.
Builders use us because we turn up when we say we will and keep the programme moving. Homeowners use us for the same reason, whether it's a blocked drain, a CCTV inspection or a repair. Same team, same standard.
Our story



Licensed drainlaying for homes, new builds and large developments. From a blocked drain to a full subdivision, first trench to council sign-off.
Quality workmanship on every job, big or small, done properly the first time.
From first contact to cleanup we care about every part of the job.
Taking full responsibility for every job and standing behind the result.
Clear timeframes, tidy sites and the same high standard on every visit.
Before a single house went up at Oliver Grove in Halswell, we had already finished the excavation and drainage for all 26 homes.
Several service lines in one trench, each with its own fittings and connections, and every one had to be right before the site could be built on.
A steep residential site with the foundations already underway, where the drainage had to be planned around the slope.
