Wa­ter pipe re­newals earn the city $96k

Kapi-Mana News - - OPINION/NEWS -

Porirua City will be re­funded nearly $ 100,000 af­ter sav­ing mil­lions of litres of wa­ter.

The lat­est wa­ter ac­count from Greater Welling­ton Re­gional Coun­cil in­cludes a credit of $96,833, thanks to mea­sures put in place in the past three years.

The coun­cil re­duced wa­ter pres­sure in the CBD, upped its leak de­tec­tion tech­nol­ogy and wa­ter flow mon­i­tor­ing, and since 2008 in­tro­duced $1 mil­lion per an­num for pipe­line re­newals.

‘‘The coun­cil de­cided in­stead of spend­ing money on main­tain­ing old leaky pipes, it was bet­ter to in­vest in new as­sets that are bet­ter for the en­vi­ron­ment and the back pocket,’’ says wa­ter and drainage en­gi­neer Des Scrim­geour.

The mea­sures taken in the past three years means the 2009 fore­casted cost of bulk wa­ter for 2010-11 is now un­der bud­get by about $400,000, and main­te­nance costs have dropped by $200,000. These sav­ings will be fac­tored into the plan­ning on in­fra­struc­ture spend­ing for the next 10-year plan.

Mayor Nick Leggett says the fi­nan­cial sav­ing is fan­tas­tic and ev­i­dence of a job well done by the wa­ter as­sets team.

With the next round of longterm plan­ning due to start later in the year, he is con­fi­dent the coun­cil will con­tinue to in­clude pipe­line re­place­ment as a pri­or­ity.

‘‘ The coun­cil recog­nises the im­por­tance of up­grad­ing the city’s core in­fra­struc­ture, and this year $2 mil­lion was in­cluded in the an­nual plan for sewer pipe re­newals. Whether it’s drink­ing wa­ter, waste­water or stormwa­ter – all three net­works need sound man­age­ment and main­te­nance.’’

Wa­ter and drainage man­ager Phil Nord­berg says keep­ing a close eye on the sys­tem and check­ing dis­crep­an­cies when they arise has saved a lot of waste.

‘‘It’s im­por­tant to be proac­tive to find the leaks,’’ he says.

‘‘ Come July 20, in­stead of writ­ing a cheque to Greater Welling­ton we will be re­ceiv­ing one.’’
