Wellington Water crews stopped a wastewater overflow in Grenada Village which flows to the Porirua Stream. Residents are asked to avoid the the Porirua Stream from Grenada Village including Tawa to the outlet at the mouth of the Porirua Harbour until further notice.

As untreated wastewater entered the stream, these areas are unsuitable for the public for wading in, fishing, or gathering food from. Signs have been put up and sampling will be undertaken tomorrow morning.

Our crews are on site today investigating damage to equipment at the Lake Ferry Wastewater Treatment Plant, which has resulted in partially treated wastewater being discharged onto land. This has been caused by recent flooding in the area. We will provide a further update as soon as possible, once our crews have completed a full inspection on site.
