Reports

 

 

7.1

Update on National and Regional directions on Water Quality

Record No: R/17/10/24422

 

Courtney Ellison, Senior Resource Management Planner, presented the report.

 

Ms Ellison outlined the purpose of this report is to provide an update to the Committee on the changing regulations in relation to managing water quality and how this could relate to the provision of Council infrastructure such as wastewater.

 

Ms Ellison advised the management of water quality nationally has become an increasingly important issue. There are a number of layers of regulation to be considered when managing water that is relevant in relation to the Te Anau Wastewater Discharge  consent, such as the following;

·         National Policy Statement for Freshwater Management 2014 review

·         Catchment Limit Setting Process

·         Regional Policy Statement

·         Water and Land Plan

·         Te Anau Wastewater Consents: it is important to note that with both the changes the NPS for Freshwater Management and the introduction of the Proposed Water and Land Plan there are now much greater requirements that would need to be met in order for consent to be granted. Improvements may need to be made to the quality of the water before it is discharged into the Upukerora in order to meet these more stringent requirements.

Members Kremer questioned how to manage the scheme in the event of an emergency and what steps would be taken to identify and deal with discharge in an event in the future, and whether provision for risk management would be considered prior to undertaking the project.

Staff were advised not to responded to the issue raised.

 

 

Resolution

Moved Member Mowat, seconded Member Cockburn  

That the Te Anau Wastewater Discharge Project Committee:

a)            Receives the report titled “Update on National and Regional directions on Water Quality” dated 10 October 2017.

 

 

 

7.2

Development of the Business Case in Support of Kepler Options

Record No: R/17/10/24190

 

1          Simon Moran, Community Partnership Leader, and Ian Evans, Strategic Manager Water and Waste, presented the report.

Mr Moran outlined the purpose is to provide an update to the Te Anau Wastewater Discharge Project Committee on the development of the Te Anau Wastewater Business Case.

2          Mr Moran advised that at its meeting on 17 May 2017 Council asked officers to proceed with development of a business case for the upgrading of the Te Anau Wastewater Scheme. It also asked that officers develop selection criteria and a process via which possible alternative disposal sites might be identified.

3          Mr Moran added that the report provides an update on the progress being made with development of the Business Case.  The Business Case currently considers scoring of options that can be undertaken under the current consent, or with a variation to that consent.  He stated it may be appropriate to review these depending on the outcome of the alternative site selection process but this is a decision that will need to be made by Council at a later date.

4          Mr Moran informed that Council has also called for expressions of interest for possible alternative disposal sites based on a set of criteria that were approved by the Project Committee.

5         

Mr Moran advised that it is anticipated that a draft of the finalised business case can be brought to Council by November 2017 with a decision to be made on whether to grant formal approval by December 2017.

Mr Evans advised that the four options outlined for consideration at the Kepler block within the Business Case document are in summary;

·         Option 1 Consented Option – pipeline to Kepler with irrigation via centre pivot with provision of land treatment via nutrient uptake through pasture and bacteria die off from both UV radiation from natural sunlight and also as treated wastewater passes through the soil. Additionally odour risk would be controlled by a trickling filter.

·         Option 2A- this is essentially similar to option 1 with addition of a membrane filter at the oxidation ponds to treat flows up to 2000m3. This would provide additional treatment for the majority of occasions.

·         Option 2B – This is essentially the same as option 1 but with a membrane filter sized to treat flows to the consented peak of 4500m3.

·         Option 3 – This is similar to option 2B with membrane treatment up to peak flow of 4500m3 but with further land based treatment through sub surface drip irrigation rather than centre pivot irrigation.

In summarising Mr Evans advised Option 1 is the preferred solution, being the considered discharge of oxidation pond treated wastewater to the Kepler Block by central pivot irrigation.

Mr Evans advised the next steps are to identify the Procurement Approach, the Financing and Funding Arrangements and the Timeframe for the preferred option.

Furthermore, Mr Evans added that if other options become available, particularly in response to the request for land that is currently open, they will be reviewed against criteria and then against the Key Constraints as outlined in the Business Case.

Mr Alan Bickers outlined his review work in relation to a draft Business Case for land treatment and disposal options for the Kepler Block; this included a new Option 2A analysis of the four options the key values, weightings, and risk analysis along with the methodology explaining the Business Case and scoring guidelines.

Mr Bickers stated that he considers that the business case has been well prepared and provides sufficient information to assist with confident decision making by the Te Anau Wastewater Discharge Project Committee and the Council.

During lengthy discussions on the report members raised a number of questions for clarification including the following;

·         Concern at the opex costings provided in regard to farming practice and baleage budgets.  Members requested assistance from a farming consultant in conjunction with MWH and staff to validate the figures provided to date.

·         Clarification as to the long term effect of irrigation on the soils

·         Why Manapouri future disposal has been included in the consent

·         Concern expressed at current consent to discharge at the Upukerora River expiry date; what are the conditions, costs and impacts of the requirements and time lines for the various steps of the consent to be met

·         Acknowledgement of the impact of the project on the restrictions and development of i.e. accommodation and hanger development at the Te Anau Airport Manapouri .
