Stormwater pipework in an open trench

Connected properly, the first time.

Getting wastewater and stormwater right protects your property and keeps council happy. We handle connections to the public network, private sewer lines, soak pits, detention and retention tanks.

As Christchurch City Council authorised drainlayers, we can make connections into the public system and arrange the inspections required.

Every line is tested before it’s backfilled, so you can be confident it works.

From connection to retention.

Council connections

CCC authorised, one contractor for inside and outside of boundary connections.

Soak pits

Soak pits sized and installed for your site.

Retention tanks

Detention and retention tanks to meet consent conditions.

Every line tested and inspected before backfilling.

Every service lines right the first time.

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.
