Drainage Contractor Auckland
Bromley Group are the drainlayers Auckland homeowners and developers rely on for residential and commercial drainage - stormwater, sewer connections, soakage systems, French drains, and full subdivision drainage networks. If water is going somewhere it should not, or your site needs a compliant drainage system from the ground up, we will sort it.
Stormwater Drainage Auckland
Auckland's rainfall puts real pressure on drainage systems, especially on older sections where the original stormwater infrastructure was never designed for today's impervious coverage. We design and install stormwater systems that meet Auckland Council requirements, connect correctly to the legal point of discharge, and handle the volume your site generates.
Whether you are adding a new driveway, building a new home, or dealing with ponding and overland flow on an existing property, we will assess the site, check the falls, and put in a system that works long term. We work across all Auckland suburbs, from Titirangi and Henderson in the west to Flat Bush and Papakura in the south, North Shore, and everywhere in between.
Residential Drainage Solutions
For homeowners, drainage problems usually show up as water pooling around the foundation, a wet lawn that never dries out, or a driveway that sheets water toward the house. These are not cosmetic issues - left untreated they cause foundation movement, subgrade failure, and structural damage.
We install French drains, subsoil drainage, surface channels, soakage trenches, and sump and pump systems depending on what your site needs. Every solution is designed around your specific ground conditions. Auckland's volcanic and clay soils behave very differently, and the fix needs to match.
Subdivision and Development Drainage
For developers and main contractors, we deliver full drainage packages for multi-lot subdivisions and commercial sites - reticulated stormwater and wastewater networks, manhole installation, kerb connections, and coordination with Watercare and Auckland Council requirements through to s224c sign-off.
We read the drainage design drawings, work to the engineer's specifications, and communicate directly with your project team. If there is a design issue on site (incorrect invert levels, conflicts with other services, ground conditions that do not match the geotech), we flag it before it becomes your problem. If you need a drainlayer Auckland-wide for the full civil drainage package, this is what we do.

The Process
How It
Works
Enquire
Fill in the quote form or call us directly. Tell us about your project: scope, location, and timing. We'll confirm we're the right fit and arrange a site visit.
Site Visit
We visit the site, take measurements, review any plans or consent conditions, and ask the questions that matter. No charge for the visit. No obligation on your part.
On-Site Delivery
Once agreed, we start when we say we will. You'll have a direct line to the crew. Any variations are flagged before the work happens, not after.

Common Questions
Frequently
Asked
A French drain is a subsurface trench filled with gravel and perforated pipe that redirects groundwater away from a structure or low point. If you have persistent wet ground or a leaking foundation, it's often the right solution.
Yes - we carry out legal point-of-discharge connections and can coordinate the inspection process with Watercare and Auckland Council.
We CCTV-inspect the existing line, identify the failure (root intrusion, cracking, collapsed joints), then either reline or re-lay the affected section. We always confirm the scope before any digging.
Yes. We install on-site soakage systems including soakage pits and trenches designed to your engineer's specification. We also carry out field permeability testing where required.
No minimum. We quote residential drain repairs and full subdivision drainage packages - and everything in between.
For civil drainage work - stormwater systems, sewer connections, soakage, and subdivision drainage - you need a drainlayer, not a plumber. Plumbers handle internal household plumbing. Bromley Group are a trusted drainlayer covering all of Auckland.
