Watercare boss concerned about Auckland stormwater. 

Auckland Council is allowing developments to occur knowing there is no adequate stormwater system and this will result in more frequent harbour spills, says Watercare chief executive Raveen Jaduram.

The wastewater system is designed for toilet and other household wastewater and, as much as practical, stormwater needs to be removed, Jaduram said in an email to councillor Mike Lee last year

The email highlights different views between council and its water business about how to deal with overflows from 41 sites into the Waitemata Harbour almost every time its rains.

About 99 per cent of the overflows is stormwater. Just 0.2 per cent, or two litres for every 1000 litres, comes from toilets.

“The use of detention tanks in new developments to slow down the stormwater flow when it rains “is not a sustainable solution. What is required is investment by council in proper stormwater infrastructure.” Watercare chief executive Raveen Jaduram.
