Wa­ter scheme up­grades in pipe­line

The Leader (Tasman) - - FRONT PAGE - CHERIE SIVIGNON

Res­i­dents us­ing the Dovedale and Eighty-Eight Val­ley ru­ral wa­ter schemes will soon have the chance to hear about pro­pos­als for up­grad­ing the sys­tems.

Tas­man Dis­trict Coun­cil util­i­ties man­ager Mike Schruer said he hoped to hold pub­lic meet­ings in early Novem­ber in both com­mu­ni­ties to out­line up­grade op­tions ahead of the re­lease of the draft 2018-28 Long Term Plan (LTP).

‘‘My in­ten­tion is to give them all the in­for­ma­tion avail­able so they can make some in­formed de­ci­sions when the LTP goes out for con­sul­ta­tion next year,’’ Schruer said.

In a re­port, he says the ef­fect on landown­ers’ wa­ter charges, should the up­grades be im­ple­mented, ‘‘is likely to be sig­nif­i­cant’’.

There is a mora­to­rium on new con­nec­tions to both schemes, which are sup­plied by creeks. Dovedale, which ser­vices Up­per Moutere, also has a per­ma­nent ‘‘boil wa­ter’’ no­tice in place that ad­vises users to boil wa­ter for at least one minute for use as drink­ing wa­ter, to pre­pare food, to wash uten­sils and teeth, for pets and as ice. It has been in place since at least 2000.

Schruer said there were also is­sues with the in­take line for the Dovedale scheme, which had four

breaks this year – three in the past two months.

‘‘It’s a pipe that’s get­ting quite old, it’s quite ex­posed in parts,’’ he said.

One op­tion was to in­stall a new line along Dovedale Rd to a new bore site. Wa­ter qual­ity ‘‘jumps up’’ with a bore sup­ply, Schruer said. How­ever, that could cost $750,000 to $1 mil­lion.

The main is­sues for Dovedale were around wa­ter qual­ity and the re­silience of the sup­ply, which was at risk in an ex­treme drought.

‘‘We don’t have backup stor­age,’’ Schruer said. ‘‘The in­take is at risk of dry­ing out.’’

The main is­sue at Eighty-Eight Val­ley was around treat­ment. There were dif­fer­ent op­tions for that area in­clud­ing an ex­ten­sion of the Wakefield Wa­ter Sup­ply.

Many peo­ple an­tic­i­pated a tight­en­ing of the Drink­ing Wa­ter Stan­dards once the in­quiry was com­plete into the 2016 gas­tro out­break at Have­lock North.

In Au­gust last year, 5500 peo­ple at Have­lock North – 40 per cent of the town – be­came ill as a re­sult of campy­lobac­ter in the wa­ter sup­ply.


Im­proved wa­ter qual­ity is one of the aims of pro­posed up­grades to the Dovedale and Eighty-Eight Val­ley ru­ral wa­ter schemes.
