Customer: Central Hawke’s Bay District Council
Location: Central Hawke’s Bay District, New Zealand
Delivered: February 2017
The project included several remote locations within the Central Hawke’s Bay region. The assets were originally going to be replaced in their entirety which would have been unnecessarily expensive and disruptive
Interflow rehabilitated the nominated culverts using a combination of both SPR™ EX – Expanda and SPR™ RO – Rotaloc pipe lining solutions.
The project was also completed in a short time frame – one week, extending the life of the assets by at least 50 years.
Central Hawke’s Bay District Council called upon Interflow to clean, line, grout and complete a final CCTV inspection of ageing culverts within the rural Central Hawke’s Bay region.
Interflow’s early involvement in the project established that relining of the culverts was going to be a more cost effective option than physical replacement, and would achieve similar results.
Interflow installed a total of 37 metres of DN900 SPR™ EX – Expanda pipe, as well as 14 metres of DN1050 and 10 metres of DN1500 SPR™ RO – Rotaloc Pipe.
Central Hawke’s Bay District Council was very pleased with the outcome of the project and anticipates using Interflow again to rehabilitate more culverts in the near future. Interflow provided substantial cost savings to the Council and minimal disruption to the surrounding communities.
Interflow is committed to offering its customers optimum solutions of the highest value for pipeline rehabilitation.
