  • Farm Environmental Plan | Central Plains Water
    CPWL advisers will help farmers with the formulation of these plans Included in these plans will be establishing a nutrient management regime for each farm that complies with the nutrient criteria for the Selwyn Waihora Zone These plans are subject to an annual audit which will be carried out by an independent assessor Any non compliance must be rectified within a specified period of time If not rectified the supply of water to the offending user will be turned off The key aims of the farm management plans are To minimise the loss of nitrate nitrogen to soil drainage water and to minimise any loss of sediment phosphorus or nitrogen to surface waters To establish an annual nutrient budget In addition the farm management plan will ensure Stock is excluded from waterways and wetlands including drains and races All native plants and native animals and their habitats are protected Water application effectiveness is maximised All irrigation systems meet industry and scheme standards CPWL has been working with consultants to review the farm management plan template that was included in the consent The template has been updated to include lessons learned from other Schemes There has been no material change to the information that the farmer is required to provide as set out in the CPWL consent The next step is to review this template with a focus group farmer board members key shareholder farmers irrigation industry representatives and farm advisors to establish if further adjustments are required CPWL are about to commence the public process to establish the Community Liaison Group One of the first jobs for this group will be to review and comment on the Farm management template The farm management plan will be rolled out to Stage 1 farmer shareholders early 2014 training workshops to assist farmers

  • Scheme Development | Central Plains Water
    a result the CPW Trust was established in 2003 The Trust is a public venture with Trustees appointed by the Christchurch City Council Selwyn District Council and Ngai Tahu In 2003 Central Plains Water Ltd was established to raise sufficient share capital to obtain the necessary consents These consents are owned and administered by the CPW Trust Water will be licenced to CPWL which is responsible for the implementation and operation of the Scheme In November 2004 4 7 million was raised via a prospectus The shares carry rights to water and while available to anyone were fully subscribed by farmers within the scheme area The initial Central Plains Water scheme proposed a water storage reservoir west of Coalgate where the Waianiwaniwa Valley opens out to the Canterbury Plains This was declined in 2009 but CPWL was given the opportunity to propose a revised run of river scheme which was consented in 2010 This allows for run of river takes totaling 65cumecs made up of 25cumecs from the Waimakariri River and 40 cumecs from the Rakaia River including 6 Synlait band 2 3 cumecs of subservient water In 2012 CPWL received a 5 million loan from the Selwyn District Council This was supported in early 2013 by 5 7 million of funding from the Ministry for Primary Industries Irrigation Acceleration Fund IAF and allowed for detailed design work to begin on Stage I of the scheme In early 2013 the Government accepted Environment Canterbury s recommendation to change the Water Conservation Order covering the Rakaia River that allows TrustPower to release water from Lake Coleridge for irrigation when the river is low increasing the reliability of the water supply The TrustPower proposal includes a canal along the north side of the Rakaia River that would link Lake Coleridge with the

  • Scheme Overview | Central Plains Water
    has resulted in significant reduction in the size of the canal through the central and northern stages The indicative size of the canal shows a reduction from 35 cumecs to 16 cumecs This will be further refined when detailed design is undertaken Pipework has been designed for Stage 1 of the scheme and this will be applicable for the pipework for most of the remainder as well STAGE 1 OVERVIEW Overview Stage 1 of the Central Plains Water Scheme irrigates approximately 20 000 hectares of farmland in the Canterbury Plains in an area bordered by the Rakaia and Hororata Rivers An intake at the Rakaia River will direct water into a 17km long gravity fed headrace or canal A network of underground pipes distribute water to shareholders downstream of the headrace The key components of Stage 1 are An intake and headworks at the Rakaia River to bring water into the headrace A headrace alongside and traversing up the northern bank of the Rakaia River to the top of the main Rakaia Terrace A level headrace along the plains to convey water north and into the reticulation system A piped reticulation system providing pressurised water to all shareholder properties in the scheme area Stage 1 Infrastructure Intake Structures The river intake is located approximately 8km downstream of the Rakaia Gorge Bridge It intercepts the stable river braid in this location The intake water is conveyed into the flow control structures sediment retention ponds and fish barrier before entering the main headrace The intake structures and fish screens are scaled appropriately for Stage 1 but designed so that they can be increased in size for future scheme stages Headrace Once past the intake structures water is conveyed into a level headrace which commences an 8km traverse up the northern bank of the river terrace The headrace crests the terrace at the 235m contour line around Earlies Pond near Steeles Road The terrace headrace was constructed within an engineered fill embankment bench rising to around 15m high and then into a bench cutting into the terrace face for the remainder of its length to eventually rise onto the upper terrace Around two million cubic metres of earth were moved to form the bench and headrace Once up onto the upper terrace the headrace travels north for approximately 10km through to Leaches Road following the most practical route through farmland The water level in this section is approximately at ground level Throughout the length of the headrace a liner was used to control seepage from the canal Construction Contractors had less than 18 months to build the 17km long headrace canal and 130km long pipe distribution network For the headrace and canal 1 9 million cubic metres of earth was moved which includes 377 000m³ of topsoil the equivalent of removing the topsoil from 125 hectares 550 000m ³ of HDPE Liner was also installed 13 bridges were built each spanning approximately 25m each 10 on farm bridges and 3 public road bridges

    irrigable area of 60 000Ha within a command area of over 100 000Ha of the Canterbury Plains between the Southern Alps to the west State Highway I and the Waimakariri and Rakaia Rivers The scheme which will be built in stages will utilise run of river water from both the Rakaia and Waimakariri rivers supported by stored water from Lake Coleridge With a current estimated construction cost of 385 million excluding on farm costs the Central Plains Water Scheme is a significant construction project for the South Island The Waimakariri and Rakaia Rivers will be linked via a 56km headrace canal running around the foothills and water from the canal will be distributed by gravity feed throughout the 60 000Ha by over 500kms of underground piping Water within the canal will be about 4m deep and approximately 25m wide at the surface The first Stage will comprise 20 000Ha between the Rakaia and Selwyn Rivers The footprint of future stages is likely to be within the Hororata Greendale Darfield Kirwee and Sheffield areas Farmer demand will dictate the extent and timing of development Contact Us Physical Address Central Plains Water Limited Level 1 114 Wrights Road Addington Christchurch 8024 Phone
