Information on our projects and activities in the Howick local board area
Wastewater from private residences and non-domestic sites goes into the wastewater network and is pumped to treatment plants for treatment and disposal. The network is extensive with 1500km of wastewater pipes spread across Upper Tamaki River, Lower Tamaki River, and Cockle Bay catchments. In the north of the local board area there are two main trunk lines: the first runs from Eastern Beach and the large pumpstation at Bucklands Beach through to Highland Park. The other collects wastewater from Mellons and Cockle Bays to a pumpstation called PS30 Howick. This joins the Howick Interceptor that travels across Botany Downs via the Pakuranga South pump station. Both main trunk lines join at Botany Creek and travel west through Pakuranga to join the Eastern Interceptor in Panmure. The Southern area of the local board area connects to the Tamaki East Interceptor which extends west to the Māngere wastewater treatment plant.
Drinking water for the Howick area primarily comes from the Ardmore and Waikato water treatment plants. The main line comes from the south and fills the giant reservoir at Redoubt Road and East Tāmaki. Water reservoirs are placed along the network to guarantee supply during times of peak demand and to smooth flows during the day. There are two main lines serving the local board area: the Howick watermain travels east through Botany, while the Hūnua 2 watermain travels west though East Tamaki and Pakuranga. In the Howick area, a significant expansion of Redoubt Road reservoir will bring more storage capacity and resilience to water supply in the area.
