Foxton
The Foxton wastewater scheme installation was started before 1924. It consists primarily of 150mm dia. GEW and steel pipe with some larger pipes up to 375mm GEW.
A pump-station in Harbour Street lifts the sewage into the delivery line leading towards the oxidation pond on Matakarapa Island. The pump-station and oxidation ponds were installed circa 1970 and these replaced the previous septic tank based treatment system. The pump station was renewed in 2003.
The Wastewater is currently treated by way of a single cell aerobic oxidation pond followed by two maturation ponds in series discharging into a drain leading towards the Foxton loop in the Manawatu River.
The discharge is made under Consent No. 3926 which expires on 31 May 2007.
The operational parameters of the Foxton scheme are:
Population served: 2,756 (1996 census)
Connections: 1,096
The key issues relating to the scheme are:
- The development of a land based disposal system should be progressed rapidly.
- The replacement programme for the older pipes needs to continue (but at a lower rate of progress).
- Access to the treatment ponds is difficult.
