Up­grade for Te Awa­mutu water in pipe­line

Hamilton Metro News - - NEWS -

Pre­lim­i­nary work will be­gin in earnest within the next month to up­grade Te Awa­mutu’s water sup­ply.

In Te Awa­mutu Waipa District Coun­cil strug­gles to sup­ply enough water dur­ing sum­mer. Water cur­rently comes from the Man­gauika Stream on Mt Piron­gia and an un­der­ground bore on Fron­tier Road.

Un­der its re­source con­di­tions from the Waikato Re­gional Coun­cil, Coun­cil is re­stricted in how much water it can take from the stream and will be re­stricted even fur­ther by 2030.

Given growth pre­dicted for the town and dry sum­mers, Te Awa­mutu needs more water now.

At the Ser­vice De­liv­ery Com­mit­tee meet­ing Tues­day morn­ing, coun­cil­lors brought for­ward a $500,000 spend to be­gin an up­grade of the Par­al­lel Road water treat­ment plant, take water from the Waikato River and pump the treated water to Te Awa­mutu.

The meet­ing heard that staff and in­de­pen­dent con­sul­tants had con­sid­ered nine dif­fer­ent op­tions to source water, in­clud­ing chal­leng­ing the ex­ist­ing re­gional coun­cil re­source con­sent.

Based on a range of fac­tors in­clud­ing cost, re­silience of sup­ply, pro­jected growth, tech­ni­cal and reg­u­la­tory com­pli­ance and tim­ing, this so­lu­tion was judged best.

The project, which was first out­lined and bud­geted in the Coun­cil’s 2015-25 10-Year Plan, is ex­pected to meet Te Awa­mutu’s fresh water needs for the next 30 years. It will pro­vide a re­silient long-term water sup­ply, en­able growth and when com­plete, will ad­dress taste and odour is­sues.

Coun­cil held off press­ing go on the project un­til it had ex­hausted a search for new water for the town via bores.

De­spite sink­ing five bores, only two sources of qual­ity bore water were found, one at Fron­tier Road and the other at Tay­lor’s Hill. The Tay­lor’s Hill bore has not been fully com­mis­sioned but test re­sults show it can only ser­vice around 1500 prop­er­ties.

But that’s not enough water to keep up with Te Awa­mutu’s pro­jected growth.

Coun­cil­lors agreed to re­lease funds to al­low ini­tial de­sign and land ne­go­ti­a­tions to be­gin. The new sup­ply could be up and run­ning by 2020, de­pend­ing on the out­come of the 2018-28 10-Year Plan.

The to­tal project is ex­pected to cost around $25 mil­lion.

The project will also end sea­sonal taste and odour is­sues which, de­pend­ing on weather con­di­tions, can im­pact on Piron­gia and Te Awa­mutu for a few weeks each year.

How­ever, th­ese is­sues would not be re­solved un­til 2020.

Coun­cil­lors were ad­vised that taste and odour is­sues could be re­solved 12 months ear­lier, but at an ad­di­tional cost of $3 mil­lion.
