The project consisted of the emergency installation of a 350 m sewerage pipeline – using horizontal directional drilling – after the sewer rising main crossing Weyba Creek broke in September 2015.
“The broken main was located in an environmentally sensitive area and close to holiday accommodation,” said Unitywater Sustainable Infrastructure Solutions Executive Manager Simon Taylor.
“The high-peak tourist season was approaching and although we had carried out a temporary solution by redirecting sewage to an alternative network, if we had experienced a high rainfall event it may have overloaded the system.
“The creek is a designated fish habitat area, some of the vegetation is protected and the nature refuge is protected habitat for several species of animal.
“We were also very conscious of the noise impact on local residents. We managed this by placing sound curtains around machinery and on sections of temporary fencing.
“This was an innovative project and we are thrilled to be recognised for the work we carried out in such a highly sensitive environment.”
