Wannon Water says the smell is part of an innovative sewer repair project that has also seen heavy steam released from kerbside equipment. 

Garth Power, Project Manager – Asset Creation at Wannon Water, said sewer pipes at 24 sites across the city have been upgraded to help ensure the long-term reliability and quality of the sewer network. 

“People in the nearby area may notice a strong resin-like odour while the project is taking place,” he said. 

“This odour, which smells like new plastic, is not toxic and dissipates very quickly.”

Mr Power said Wannon Water has engaged contractors to strengthen and repair the damaged sections by winching a resin-saturated felt tube in the existing sewer main. 

“This is then steam-cured so it hardens and creates a strong pipe-within-a-pipe,” he said. 

“The rehabilitation method has been used successfully around the world for more than 40 years. It avoids the need for large-scale digging and replacement, therefore minimising disruptions for residents and businesses.”

Mr Power said the relining project is expected to be completed by end of July. 

Work has previously been completed in Hamilton, Heywood, Casterton, Coleraine and Simpson.
