Auckland Stormwater Drainage Installation

We size systems for Auckland's actual rainfall, not a comfortable average. The storms that cause damage here are short, heavy bursts, and a system that handles steady rain perfectly well can be overwhelmed in ten minutes by the sort of downpour we get several times a year.

We deal with the council side of things so you don't have to work out which forms apply to you. Knowing what needs consent, what needs inspection, and what the connection requirements are saves a lot of back and forth.

We also locate existing services before we dig. Auckland sections are full of unmarked pipes and cables, and finding them with an excavator bucket is expensive for everyone involved.

We get the gradients right and we check them. A stormwater line laid with inconsistent fall traps silt in the flat sections, and over a few years that builds up until the pipe is half-blocked and nobody knows why the yard floods.

We put access points where they're useful. Cesspits and inspection points in sensible locations mean the system can be cleared in ten minutes years from now instead of needing someone to dig up a driveway to find the blockage.

And we test under real flow before we backfill. It's a lot easier to fix a problem while the trench is still open than to discover it during the first serious storm after we've reinstated your lawn.
