Ex­treme weather de­lays dis­tricts wa­ter projects

Bush Telegraph - - FOCUS ON FARMING -

Sev­eral re­cent ex­treme weather events plus a fire, have caused sig­nif­i­cant de­lays to work on a num­ber of ywa­ter pro­jectsz within the district.

Dave Wat­son, Tararua District Coun­cil, group man­ager plant and prop­erty, says the de­lays have been un­avoid­able, as work on projects such as the Woodville im­pounded sup­ply, Aki­tio wa­ter treat­ment plant and Pon­garoa ru­ral sup­ply reser­voir are all very much yweather de­pen­dent.z

yCur­rently the cover in­stal­la­tion at the Woodville site is un­der­way, ap­prox­i­mately 80 per­cent is in place, but fur­ther weather con­di­tions could de­lay the com­ple­tion. Once the cover is com­pleted, the bal­last weights will be in­stalled on top of the cover which al­lows the cover to sit on top of the wa­ter level and drop and rise with the level.

yIf we could an­tic­i­pate 2 weeks of good weather we could al­most get it com­pleted and hope­fully start putting wa­ter into stor­age,z he said.

The re­cent storms have also af­fected wa­ter at Pon­garoa, which be­came very tur­bid (dirty) af­ter the heavy rain­fall in the hills.

Mr Wat­son says while the ru­ral sup­ply reser­voirs at Pon­garoa are cur­rently rou­tinely be­ing cleaned, they will have to wait un­til any sed­i­ment in the sys­tem has been elim­i­nated and the chlo­rine lev­els re­turn to the re­quired lev­els for cus­tomer use. Three clear lab sam­ples need to be re­ceived be­fore the Boil Wa­ter No­tice can be lifted.

In Aki­tio the treat­ment plant, elec­tri­cal in­stal­la­tion and pipework has been com­pleted. Mr Wat­son says a trans­ducer and ca­ble now needs to be yploughedz in from the plant to the first stor­age tank on the hill. This has been held up with wet weather and the need for heavy ma­chin­ery to com­plete the work.

yThis will al­low staff re­mote con­trol through our Scada teleme­try sys­tem for the treated wa­ter pro­duc­tion and au­to­matic shut­off of the plant, once de­mand has been met. With­out this con­trol, treated wa­ter would run to waste.z

While bad weather was re­spon­si­ble for many de­lays, work on the Pahiatua Reser­voir was de­layed due to fire.

With the reser­voir roof struc­ture and trusses at­tached, the fab­ri­cated com­po­nents for the reser­voir walls, which were in Wellington await­ing trans­porta­tion to Pahiatua, were de­stroyed in a fire.

Mr Wat­son says re­place­ment com­po­nents will be dis­patched from Syd­ney on the 18th Oc­to­ber with a de­liv­ery date 1st Novem­ber.

yWe are wait­ing for the re­vised con­struc­tion timetable.

yOnce they are on site we will have an idea of when this will be com­pleted.z
