Quality drainlaying. Every time.

Our small team of experienced drainlayers have been proudly servicing the Nelson Tasman region for over 20 years, specialising in residential, rural and commercial drainlaying. After a change of ownership a few years ago, we have now rebranded from Terry Westley Drainlayers to Chethams & Co Drainlaying.

We might have a new name, but nothing else has changed - you’ll still receive the same exceptional service from the same skilled team.

Our work

Berryfields & The Meadows

We have spent a significant amount of time in the Berryfields & The Meadows subdivisions over the past few years, installing sewer and stormwater drains for more than 285 residential properties. That’s a whole lot of pipe!
Sandy Bay | Jennian Homes

We couldn’t get digger access to this technically challenging site, so there was a lot of shovel work required to install sewer and stormwater drains here. But with views like this over golden sands, who’s complaining?
Hoddys Road | Salter Builders

This stunning property perched on the edge of the estuary required sewer and stormwater drains, a retention tank for water storage, firefighting couplings and connections to an existing septic tank.
