Update on Woodville Water

Monday, 15 May 2017, 8:00am

The 20ft container complete with the pumps and generator installed has arrived on site. The pipework between the Kliptank and the reticulation will be connected and commissioned this week. The 2000m3 tank is full ready for use when required.

The work at the impounded supply site has stopped for the season due to the winter ground conditions.

The recent heavy rainfall has caused a few issues. The most severe was the increased water level of the Mangapapa Stream; turbidity (cloudiness) of the water became very high and this prevented us taking any usable water to treat for well over 24 hours.

With help of the Woodville and Dannevirke Fire Brigades, we were able to pump the water from the Kliptank back into the reticulation, which gave us some breathing space over the weekend to recover.

The treatment team worked over the weekend to treat the incoming water and refill the reservoirs. By the weekends end, we had three quarters of our storage back and leading up to the Easter weekend, we had the Kliptank storage tank two-thirds full again.

We would like to thank everyone who worked tirelessly to resolve this issue, as well as extend our gratitude to the Woodville residents for their efforts to conserve water during this time.

Work has ceased in the pond area for the last four weeks as weather has been a real deterrent to any excavation work and another update will be provided in two weeks.

Update on Woodville Water

The Woodville Impounded Water Supply earthworks has been progressing well. Almost 50% of the excavation work has been completed. Weather interference has put us behind this week due to the heavy rainfall last weekend.

Approval from the engineer to construct the internal wall has been granted. The excavated material on-site has passed the compaction and shear test required for work to proceed.

The Kliptank pumps have arrived now, and are at the engineer’s site getting fitted together with the pipework into a 20’ container. This will then be delivered to the McLean Street site ready for installation.

The weather / rainfall has been kind to us while all the work has been going on, as the Mangapapa Stream has had an above normal water flow, which in turn has allowed us to maintain water supply to the town without any water restrictions.

Update on Woodville’s New Water Storage Facility

We are pleased to advise that we are about to excavate, line and cover the existing Woodville water town reservoir. It is now emptied and drying, ready for construction of the bigger, sealed and covered reservoir. This work is planned to start in late December and may require more than twelve months to complete – particularly if the weather is against us.

We are keenly aware that the reduced storage capacity during construction makes our supply of water more vulnerable.   Storm events make our water source, the Mangapapa Stream, “turbid” requiring us to either stop taking water, or the water will need more filtering and flushing. Drought means we may not be able to access enough water.  Council’s water resource consent also has limits, as set by Horizons Regional Council.

Water Restrictions Coming

Council is urging all residents to conserve water where at all possible as we head into summer.  Water restrictions will start early in the New Year.  We will notify people in the usual way when this is to commence.  These restrictions may be necessary for longer than normal, as construction progresses.

To increase reserves of water, Council is installing a large tank outside of town and some tanks in town.

A large temporary “clip-tank” for treated water will hold 2,000m3, measuring 35 metres across. With Woodville’s existing storage this means that, with careful use, there will be up to three (3) day’s supply of normal use in reserve.  The anticipated time for this clip-tank to be supplied, erected and pipework connected is late January, becoming operational in February 2017.

A second measure is to install four temporary 30m3 water tanks and supply treated water. These will be in place before Christmas. They will be located at McLean Street (from the old Infracon Yard) and Ross Street (beside the Community Centre). Residents of Woodville are welcome to fill their own water containers from the taps supplied for supplementary water or drinking water.  Please make sure drinking water containers are clean before use.

The new water storage facility will offer the community a long-term, sustainable, resilient water supply that will work in well with the treatment plant that was installed in 2014.

During the coming months, Council appreciates residents’ patience whilst we construct the new facility.

Update on Woodville Impounded Water Supply Project

PROJECT UPDATE

Council has finished emptying the current impounded supply in preparation for the enlarged impounded supply excavation.

Once the weather has improved and the groundwater has dissipated, the area will be dry enough to enable the contractor to commence the build. Following this, the new liner will be put in place and the cover will be installed.

EFFECTS ON SUPPLY

As a result of this work, water restrictions will likely need to be imposed earlier than normal (as there will be no extra storage leading into the Christmas and summer period) and some restrictions may start as early as December.

To ease the effects of water restrictions, Council will be installing several 30,000L tanks to allow residents to collect water for home use while this work is going on.

The 30,000L tanks will be placed at the following locations:

  • Two tanks will be placed on McLean Street (in Tararua Roading’s old yard)
  • Two tanks will be placed on Ross Street (by the Sports Stadium)

Note: the hoses and attachments for filling containers will be accessible from the footpath.

Additionally, two 750L transportable plastic tanks will be available for Woodville residents to maintain any work programmed around their properties (i.e. to water-blast a house or building prior to painting). These can be booked through the Council Service Centres and will require collection from Dannevirke (you will need your own trailer to transport).

FURTHER INFORMATION

Further information on this project will be provided via Bush Telegraph, Council Facebook page, Council website and articles similar to this. If you have any enquiries regarding the upgrade, please contact Andrea on 06 374 5341 during business hours.

Woodville Impounded Supply Project due to commence

The Woodville Impounded Supply project is very close to starting.

A temporary 5000 cubic metre storage pond will be constructed first - in order to provide the town with approximately four days storage - prior to the large dam being excavated and lined.

At present, Council is busy emptying the current impounded supply in preparation of the site. Once the weather has improved and the ground water has dissipated, the area will be dry enough to enable the contractor to commence the build. Following this, the new liner will be put in place and the cover installed.

This means that water restrictions will need to be imposed earlier than normal, as there will be no extra storage leading into the Christmas and summer period - some restrictions may start as early as December.

To ease the effects of water restrictions, Council would like to advise that they will install several 30,000L tanks, to be situated around the township, to allow residents to collect water for home use while this work is going on. Council will advise the location of these tanks nearer to the time.

Additionally, two 750L transportable plastic tanks will be available for Woodville residents to maintain any work programmed around their properties (i.e. to water blast a house or building prior to painting). These will be able to be booked through Council Service Centres and will require collection from Dannevirke (you will need your own trailer to transport).

Further information will be provided via letter drops, Bush Telegraph, Council Facebook Page, Council website and articles similar to this. If you have any enquiries regarding the upgrade, please contact Andrea on 06 374 5341 during business hours.

Work commencing on Woodville Water Supply

Work will soon begin on the lining and covering of the Woodville Reservoir.  This work is required to mitigate the taste and odour problems that have affected the Woodville supply for many years. 

Providing covered and lined water storage will prevent the growth of algae that cause taste and odours.  The work is similar to that completed for the Dannevirke Water Supply several years ago.

The work includes:

  • Empty and dry out the reservoir - to enable work to commence
  • Build a small pond to assist supply
  • Increase volume and improve shape of the pond for lining
  • Line the pond (approximately 2 hectares)
  • Cover the pond (approximately 2 hectares)

Before earth moving machinery can commence work, the reservoir will be emptied and allowed to dry.  Emptying of the reservoir is planned to commence in the last week of October 2016.  The balance of the work will take several months and is due for completion prior to winter 2017.

With the reservoir out of service, this leaves the catchment as the only source of water for Woodville.  This poses two difficulties for the water supply:

Firstly, storms in the catchment can cause water to be very turbid.  Typically, when this occurs, the reservoir is used to provide cleaner water to the plant.  This means that there may be a need to treat less desirable water and this could result in discoloured water in Woodville.

Secondly, the amount of water available to the Woodville supply will be restricted to what can be taken directly from the catchment. 

Usually during summer, the catchment supply is supplemented by additional water from the reservoir - because the reservoir is out of service, there will be less water available over summer and it will be necessary to reduce water use.

Water restrictions are anticipated and Council will be providing additional information in respect of both the work and water saving measures. 

While current effects on the supply in general terms are known, the pending work and the Woodville supply remain subject to the effects of weather, i.e. a summer of frequent light rain would be ideal to operate the water supply, while a hot dry summer would be ideal to complete the work in the reservoir.

Further information will be provided via letter drops, Bush Telegraph, Council Facebook Page, Council website and articles similar to this.  If you have any enquiries regarding the upgrade, please contact Andrea on 06 374 5341 during business hours.
