Plenty of variety for civil works specialist
Clearwater Civil offers a comprehensive suite of services including drainage and reticulation, roadworks and asphalting, kerb and channel work through to earthworks and haulage.

Demand for civil infrastructure services is on the rise in Dunedin and that’s fuelling plenty of work for trusted local operator Clearwater Civil Ltd.
With an experienced full-time staff of 35 supplemented by trade staff and a large fleet of equipment and machinery, Clearwater Civil offers a comprehensive suite of services including drainage and reticulation, roadworks and asphalting, kerb and channel work through to earthworks and haulage.
In recent months, Clearwater Civil has been hard at work on a number of large civil works projects in Dunedin and the wider region, demonstrating the breadth of its capabilities.
Westwood Sewer repairs, Brighton
Under contract to City Care, Clearwater Civil started work last July to repair collapsed sewerage pipes.
The job required having to replace some 200 metres of pipe, reline the southern end of the sewer and install a wastewater storage chamber.
The depth of the line (up to four metres), sandy ground and a high water table added to the challenges of the work.
“We had to use pumps the whole time, including sewage pumps to bypass the sewer for six months,” says Clearwater Civil’s managing director Gus Clearwater.
Putting in the large storage chamber was a mammoth task in itself, with pumps working 24/7 for a month to keep groundwater out ahead of installation.
The storage tank had to be strapped to concrete ballast to hold it in place, before the area around it was backfilled. The work was completed in May.
Slip clearance, Beaumont
In February, the Clearwater Civil team started work on a remote site associated with Trustpower’s Waipori Hydroelectric Power Scheme to fix a slip affecting a water race feeding into the scheme’s reservoir, Lake Mahinerangi.

Staff on the project, which was nearing completion in early May, stayed at a house in Lawrence to be close to the site.
In total, 14,000 cubic metres of soil was excavated from the slip and drainage installed (using benching and compacting).
“It was up on the back of a forestry block on Department of Conservation land,” says project manager Darcy Pine.
“It was really remote and the topography was very steep so access was pretty tough and logistically it was hard to get our gear in there.”
As well, the team from Clearwater Civil installed a large concrete box culvert further up the race, as a result of another slip in the area.
Carparks, Portobello Aquarium work
When Portobello Marine Studies Aquarium’s steeply sloping gravel carpark area needed attention earlier this year, Clearwater Civil was booked to do the job.
“It involved a lot of kerb and channel and drain-age work, installing sumps and outlet pipes, before asphalting and sealing it,” says Darcy.
“From a surfacing perspective, the steepness of the site was the main challenge.”
Health and safety was a key priority on this project, given the high use of the site by both scientists and various visiting school groups.
“We made sure there were clear paths available for safe access.”
Locally owned and operated Clearwater Civil Ltd was founded by John Clearwater, who started his working life on the family farm at Cape Saunders on the Otago Peninsula.
Over several decades, his small rural services enterprise grew into today’s locally owned and operated company with extensive expertise in earth-works, civil construction and utility installations.
With John and wife Sharyn having taken a step back from the business, their sons Brad and Gus are proud to be managing the family firm.
“Success starts with people and we have a great team, 100 per cent,” Gus says.
“We always strive to do a good job and, fundamentally, that’s how we continue to build our reputation.”
