WASTEWATER OVERFLOW - SILVERSTREAM, UPPER HUTT
WASTEWATER OVERFLOW - SILVERSTREAM, UPPER HUTT

Our crews have stopped the overflow as of 12:30pm, and are now working on the full repair.

Residents are asked to avoid the following areas until further notice:
- Hutt River/Te Awa Kairangi downstream of Silverstream, including the river mouth in Petone
- Petone beach

While the wastewater overflow has been stopped, untreated wastewater was entering Hutt River/Te Awa Kairangi. This means that these areas are unsuitable for the public to swim, fish and collect food from. Water quality testing has begun and will continue for at least 72 hours or until results return clear.

Mt Albert sludge pipeline repair success

In late January 2020, following the burst in the two wastewater sludge pipelines buried in a tunnel deep under Mt Albert, Wellington Water engaged engineering firm Stantec to identify repair options and manage the project.

Brian Perry Civil were then engaged as the lead contractor to undertake the enabling works and to manage the other contractors working on site.

A long list of options was quickly whittled down to a shortlist of two options for relining the existing pipes.
From the shortlist SaniTube, from German Company, Amex Sanivar, was selected because it offered the best value for money, could be installed quickly and highly experienced New Zealand agent and installer Hadlee and Brunton was able to undertake the work.

Despite the additional challenge of the global pandemic both pipes were successfully relined by the end of May 2020, thanks to the multi-disciplinary team brought together to deliver this innovative repair.
