Central Hawke’s Bay District Council wishes to notify prospective selected suppliers of a tender (RFT) for a build contract to deliver upgrades to the main trunk sewer from McGreevy Street to the Waipawa wastewater treatment plant (WWTP).
The sewer is predominantly located within private property and is known to have poorly-sealed joints that allow significant groundwater infiltration and tree root ingress into the pipework.

The objective of the renewal/rehabilitation project is to provide a robust, sealed sewerage connection from the town centre to the wastewater pond at the WWTP. The programme forms part of the Big Water Story and has been allocated budget in year one and two of the upcoming Long Term Plan (LTP).

The Waipawa trunk sewer main is a 375mm diameter earthenware pipe which spans for 2.2km east of Waipawa town centre. The trunk main was installed in 1910 and has always been intended as only a wastewater-conveyance system. In practice, anecdotal observations and flow monitoring studies have confirmed that significant stormwater flows enter the main during rainfall events. The additional flows are known to result in surcharging of manholes and backing-up of domestic flows within residential properties.
