Water scheme upgrades in pipeline
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.
