P03 – Construction of Bridges, Culverts or Earthworks affecting LWIC Races Policy
LWIC appreciate that it will be necessary from time to time for landholders to build bridges across LWIC canals for stock, vehicle and irrigator access.
This policy aims to ensure that such structures are safe and are built in a sound manner that does not compromise the integrity of our network nor make it difficult for maintenance on our races,
- Any landholder who wishes to erect any structures on or over LWIC races must first have written permission from the Race Manager.
- This applies to any earthworks or engineering on, in or adjacent to races which may affect the integrity of our race network.
- Applications to erect bridges or make changes should be made in writing to the race manager.
- Application forms will be made available to shareholders.
- The race manager must be supplied with engineering certificates from a qualified certifying engineer in the form of a PS1 and PS4 documentation to ensure that the structure is safe and fit for purpose.
- Structures must be compliant to Local body regulations including Building consents
- The race manager may also stipulate the exact location of such bridges or specify certain design requirements so that access for maintenance of races by LWIC staff and contractors is not compromised.
- All structures will remain the property of the landholder and must be maintained in good condition, failure to do so will result in the structure being removed at the landowners cost providing adequate notice is given to allow landholders to rectify any faults in the structure.
P06 – SPRAY CONVERSIONS / EXISTING SYSTEM UPGRADES
This policy has been created to ensure that the correct application procedures are followed when a shareholder(s) wish to convert an existing border-dyke property to spray irrigation or upgrading an existing spray irrigation system including new irrigation.
It is important that LWIC obtain this information from shareholders prior to the commencement so assessments can be made on the ability to supply water at the requested point of take, the effects on scheme operation, environmental impact and any other issues that may arise.
- Shareholders must contact and discuss any proposed new irrigation system with the Race Manager prior to system design.
- Application forms must be completed and submitted for approval by the Board of Directors.
- Incomplete applications will not be accepted.
- All new irrigation systems must be designed and installed according to the “Irrigation Code of Practice and Design Standards”.
- A design approval certificate must be obtained before any construction starts.
- The Company must be informed once construction is completed, and an assessment will be done to ensure all LWIC requirements have been met.
- The conversion (or upgrade) will be signed off in the form a letter of acceptance from the Company once an assessment has been carried out to ensure that all requirements have been met.
PO4 – Overdue Accounts Policy
- Accounts that remain unpaid after 1 month should be reissued with a reminder stamp.
- If the account remains unpaid after two months then a note on the account will inform the debtor that if the account remains unpaid after the 20th of the month an interest penalty fee of 6% greater than our borrowing rate, to be set on an annual basis at the start of the each season will apply to the next account.
- Accounts that are outstanding after three months will have a letter attached to them, warning the overdue debtor that they risk having the right to take water withdrawn until the account is settled.
- If the account is not settled by the end of the forth month after the account is issued then the company will cease to supply water to the debtor if they are shareholders of the company and water access will only resume after the account has been settled.
The above policy does not apply to accounts that are under dispute (see disputes policy)
LWIC accepts that there may be extenuating circumstances that arise that should allow additional time for payment without penalty, these may relate to personal situations around health or family, this policy is not intended to override extended credit granted for compassionate reasons.
Any terms outside of this policy should be ratified by the board, including extenuating circumstances as described above.
P08 – Storage of Stock Water Policy
- Our primary business is the seasonal supply of irrigation water to farmer shareholders; Industrial shareholders have a year round supply and pay additional rates to cover this provision.
- The company allows its shareholders to utilize irrigation water for stock water purposes providing they are covered with the appropriate share allocation.
- Shareholders should not expect to have access to stock water all year round as the company needs to shut down races in the off season for maintenance.
- Shareholders that rely on LWIC for stock water should have adequate storage or an alternative supply for at least 4 days.
- Using irrigation water for stock water outside the irrigation season is a privilege not a right.
- If LWIC can supply stock water at no additional cost to the scheme then it should endeavour to do this but this action should not compromise any maintenance programme nor should it detract from water use efficiency.
P07 – Effluent Policy
Purpose: To ensure that all water as it travels through the LWIC scheme maintains original water quality so to not cause any contamination to downstream users. This can include other irrigators as well as town water supply.
Backflo Prevention Compulsory and tested Annually
• It is a compulsory requirement that all LWIC shareholders with spray irrigation systems that incorporate the application of any fertilisers/ chemicals or effluent have a back flow prevention valve fitted to their system to avoid contamination of company races.
• The minimum requirement is a Chemigation check valve of such a design that allows the unit to be tested.
• It is a requirement that all backflow prevention valves be tested annually prior to the start-up irrigation systems, and a fully completed test certificate be submitted to LWIC for sign off, once every 3 years. To be checked during the FEP and Audit process.
VRI rules for Effluent Spreading
• The main race and any other races that supply potable water to the town of Oamaru or Alliance Pukeuri may not have a pivot carrying effluent or fertigation pass above them regardless of the use of GPS technology, this is to maintain the integrity of this water and reduce risk of contamination due to system failure.
• Where a shareholder has a pivot or a lateral irrigator and it is to be used for effluent spreading and/or fertigation and this pivot/lateral crosses or runs alongside a water race and/or drainage channel, a GPS controlling system must be fitted. The system must be programmed to ensure that no effluent or fertiliser is able to enter and contaminate the water within the race/channel.
• All shareholders to be compliant with ORC Plan Change 8 Effluent Rules
• Effluent and fertigation discharge is not allowed to come within 20 meters of a water race, farm drain or boundary
• To land within 50m of a lake, river, bore, soak hole, Regionally Significant Wetland
• No ponding or overland flow or discharge to saturated soils (above field capacity)
• All Travelling irrigators must be fitted with “fail safe” technology
Application Reports for new Irrigation Systems with Effluent
• As per ‘conversions policy’ effluent (injected or underslung) discharge associated with new pivot installations must be discussed with Race Manager prior to design approval and a site visit of new effluent area must be conducted by LWIC staff.
• Any new effluent discharge system upgrades must be in consultation with LWIC staff.
• Effluent discharge areas will be checked at least once every 3 years by LWIC staff when upgrading Farm Environment Plan Maps.
Breach of Effluent Policy
• If for whatever reason a breach occurs, the LWIC Race Manager or Environmental Manager should be notified immediately. Application records may be required, and the shareholder should be prepared to supply these urgently. LWIC race manager should then notify the Chair and together they will consult and format an action plan.
PO9 – Water Meters Policy
LWIC require that all shareholders with a shareholding of more than 20 shares have water meters installed at their point(s) of take by the 1st September 2015.
In order for the Company to ensure the continuation of a reliable and fair distribution of water to all of its shareholders it is Company policy that water meters with telemetry units must be fitted to all existing irrigation pumps.
LWIC have had a policy in place since 2010 that all new spray irrigation (BDK – Spray conversions) installed water meters.
- Shareholders must check with LWIC for correct rate of continuous take before installation.
- Meters must be ECAN compliant pulse output magFlow type.
- Meters must be installed by an ECAN approved installer.
- Shareholder pays for meter(s) including installation, meters remain the property of the shareholder.
- LWIC pays for telemetry unit(s) including installation, telemetry units remain the property of LWIC.
- Meters to be maintained and calibrated every 5 years at the cost of the shareholder.
- Shareholders pay an annual fee for Telemetry data presentation for each pumps.
- Shareholders with 20ha or less are not required to install water meters.
P10 – Water Ordering for Spray Irrigation
LWIC are seeing a noticeable increase in the transition from border- dyke to spray irrigation, the management of the LWIC race network which was designed predominantly for border- dyke irrigation is becoming increasingly more difficult to control.
This Policy aims to ensure that the supply to irrigators in the lower reaches of the Scheme is not compromised due to the current “on demand “policy that spray irrigators have historically adopted.
Pre ordering of water for spray irrigation may not apply to everyone, location, volume and method of application will be assessed by the Race Manager.
- Water must be ordered at least 12 hours prior to starting.
- Water orders must be submitted must be submitted online between the hours of 6:00am and 6:00pm, or alternatively to the LWIC office, via e-mail or telephone between the hours of 8:00am and 12:00 pm Mon –Friday. Water orders for weekend starts must be submitted before 12:00 pm Friday .
- Water orders must include required flow rate and hours required.
- 8 hours’ notice is required for premature shutdown. (Race men can be contacted in emergency shutdown situations).
- Irrigators are not permitted to take more than their allocated continuous rate of L/s per ha.
- Water takes will be monitored via the telemetry on pump flow meters.
- Irrigators who start or stop pumps without notification or a genuine explanation will receive 1 verbal warning, 1 written warning, followed by water being denied or cut off.
P16 – Stock Exclusion Policy
Purpose: To ensure that all water as it travels through the LWIC scheme maintains original water quality so to not cause any contamination to downstream users. This can include other irrigators as well as town water supply
LWIC Stock Exclusion – the following is prohibited
• Any dairy cattle, with access to flowing water anywhere on your farm.
• Any beef cattle, pigs, or deer with access to any flowing water (regardless of width) in irrigated or forage crop paddocks. Temporary fencing can be adequate.
• Any beef cattle, pigs or deer with access to any flowing water on dryland and pasture paddocks stock exclusion to be determined through their Farm Environment Plan
• National Standards (NES) for stock exclusion rules from 2023 onwards that trumps the above
• Sheep only to graze LWIC irrigation races
Breach of Stock Exclusion Policy
• If for whatever reason a breach occurs, the LWIC Race Manager or Environmental Manager should be notified immediately. The Enforcement Procedure will then be initiated.
