7.2         Wastewater Activities Report

File Number:           A11179054

Author:                    Radleigh Cairns, Environmental Programme Leader

Authoriser:             Nic Johansson, General Manager: Infrastructure

 

Purpose of the Report

1. The wastewater activities report provides information on the current activities in the wastewater area.

 

Discussion

2.       Desludging of Pond One

Staff were looking into a possible variation to RC 62881 (Seepages consent) to assist the planned desludging works on pond 1 due to begin Oct 2020. Current advice is that any impact of desludging on the seepage rate can be managed through practical controls and management of the level of the pond 1, and so the desludging can be managed within the current consent conditions. Monitoring of seepages during the final effluent pipeline upgrade works (where pond 1 has been offline) has identified a significant reduction in seepages.

 

3.       UV Plant

The UV Plant has been running well over the summer period and testing of the discharge has shown results well below consented limits. Upgrades to more banks of lights is still required, and staff are working with the contractor to get this completed.

 

4.       Final Effluent Pipeline Upgrade

The Final Effluent Pipeline upgrade is progressing well with works about half way through the project. The dry weather has allowed for faster laying of the pipe with less dewatering and sheet piling required. The project is on track for completion in July 2020

 

5.       Receiving Environment Sampling

Over the summer period, sampling of intertidal shellfish, the receiving waters and shellfish around the outlet is undertaken. Results to date show no evidence of impacts from the discharge on the receiving environment. An assessment of the condition of the diffuser was also undertaken showing it to be in good condition and working as intended.

 

6.       5 Yearly Monitoring, Upgrade and Technology Review Report

Good progress has been made on the Cultural Report being undertaken on behalf of the tangata whenua committee members. It is proposed that a workshop will be held in mid to late March for the committee to go through the draft cultural report alongside the draft 5 yearly MUTR report and make any recommendations prior to the reports being sent to the Bay of Plenty Regional Council.

 

7.       Regional Best Practice Guidelines for Wastewater Overflows

The Regional Guidelines developed by the Regional Council lead Wastewater Management Group are being incorporated into council’s current response and reporting processes. Copies of the Guidelines have been forwarded to tangata whenua members of the committee for their recommendations on how best to engage local iwi and hapū on notification requirements.

 

8.       Landward Section of Outfall Upgrade

TCC has received the Cultural Impact Assessment (CIA) from the Ngā Potiki a Tamapahore Trust and has reviewed the recommendations in the report. Staff are currently drafting a response. The earthworks consent is scheduled to be lodged on 1 March 2020 subject to an archaeological investigation report and final sign off from the landowner (MPBI).

 

9.       Marine Outfall Review 

In mid-late 2019 Council initiated a review into potential marine outfall options (first reported to the WWMRC via DC216 on 31 July 2019).  The outfall is limited in its capacity due to its poor condition, and based on current growth predictions, a replacement (or rehabilitated) outfall would need to be operational by 2028 to cope with peak flows.  The outfall cannot physically withstand the pressures required to deliver the consented maximum rate of 900 L/s.  Presently the outfall is capped to a flow of approximately 600 L/s.  The review has been initiated now in order to meet the 2028 timeline.

The current focus for the outfall review is determining the viability of relining in lieu of constructing a new outfall.  To assess this, the following work packages have been initiated (or in some cases completed already):

Feasibility Study:

­  A relining feasibility report was prepared by Alta Consulting in October 2019.  This report identified and reviewed the feasibility of relining or other retrofitting technologies available which could be used for extending the design life and operating pressure of the outfall.  For each method, a methodology, implementation programme, risk assessment and high-level cost estimate was devised.

­  The report concluded that the following options are most feasible:

§ Full length slip lining of the 950m long marine section using a PE structural liner.

§ Full length slip lining of the 950m long marine section using a non-structural liner e.g. Primus liner.

§ A partial relining of the marine section using Partial Cured in Place Pipe (CIPP) along a 600m length of pipe from the beach manhole towards the diffuser.

§ Relining a 450m length of the existing beach section and land section pipes using Partial Cured in Place Pipe (CIPP) between the existing beach manhole and proposed crossover location between the existing pipeline and the proposed land section replacement pipe.

­  Alta concluded that further investigations were required to progress the above including; an updated condition assessment of the marine section (dye testing/CCTV), characterising any enabling works, and undertaking a hydraulic assessment to determine acceptability in terms of design and operational requirements.  These aspects are discussed below.

 

Dye Testing and CCTV Inspection:

­  During installation, the outfall pipeline sustained some damage to the joints during a significant storm and repairs were subsequently carried out.  Previous investigations and reporting of defects last occurred in 2006.

­  To determine the presence of leaks now, we propose dye testing over the coming two to three months.  This will inform where along the length of the pipeline the leaks are occurring.  This work will be carried out in accordance with an existing consent held for this purpose.

­  The Alta report also recommended a CCTV inspection to assess the condition of the pipeline.  This will inform the presence of any joint displacements or grouting/obstructions/debris which may need to be addressed prior to relining occurring. 

 

Enabling Works:

­  Continuous discharge of treated wastewater flows would need to be maintained whilst any relining occurs.

­  Treated outflows can be held in storage at the Te Maunga wetland ponds for approximately two days in dry weather, provided the ponds are pumped down in advance.  Given this short timeframe, an ongoing means of discharge is therefore required as it is anticipated that relining will take some weeks (possibly months if weather conditions result in delays).

­  The preferred approach to the ongoing management of flows is to utilise a bypass pipeline to convey flows from the outfall pump to the coast.  Ideally the pipeline would be located within the easement already in place for the existing pipeline.  To facilitate relining, we need to gain access to the beach manhole also located within the easement for work vehicles and machinery.

­  We are currently working through the planning and Heritage New Zealand requirements associated with this bypass pipeline system and the construction of the access track.  These requirements are extensive given the number of planning zones (and Wahi Tapu area) which must be traversed.  We are looking at the construction methodology associated with each to minimise impacts on the dunes, beach and any social, archaeological and cultural effects.

­  Any resource consent application and application for an archaeology authority will also need to be accompanied by a robust alternatives assessment, cultural impact assessment and archaeology report – the preparation of these are underway.

 

Landowner Engagement:

­  Initial discussions with directly affected and adjacent landowners have been held to advise of the planning work underway, seek approval in principle to any relining works should they proceed, and approval for any access required for investigations.  This engagement will be ongoing as planning and investigations progress.

 

Hydraulic Assessments

­  Beca have completed an initial hydraulic assessment on a relined outfall.  This has informed a range of pump station and other pipeline upgrade options for further consideration, and will ultimately feed into the preparation of cost estimates for relining as compared to construction of a new outfall. 

A further report back to the WWMRC will occur on completion of the above components – possibly May/June.  We hope to be in a position thereafter to make a recommendation regarding the viability of relining and if favourable, initiate further design and consenting phases.

 

Next Steps

10.     Further updates will be provided at the next Wastewater Management Review Committee (WWMRC) Meeting.

7.3         Draft Environmental Mitigation and Enhancement Fund Policy Manual

File Number:           A11184353

Author:                    Radleigh Cairns, Environmental Programme Leader

Authoriser:             Nic Johansson, General Manager: Infrastructure

 

Purpose of the Report

1.       To inform the Wastewater Management Review Committee of progress on the review of the draft Environmental Mitigation & Enhancement Fund Policy Manual.

Discussion

2.       RC 62878 requires Tauranga City Council (TCC) to establish a fund (Environmental Mitigation and Enhancement Fund or EMEF) of not less than $250,000. The purpose of the fund shall be to fund and facilitate measures and initiatives (particularly in the upper Tauranga Harbour) to:

(a)     Avoid, remedy or mitigate the actual or potential effects of the Wastewater Scheme (in its broadest sense); or

(b)     Acknowledge and provide mitigation by way of environmental compensation for ongoing adverse environmental effects (including by way of offence to tangata whenua cultural and spiritual values) associated with the wastewater scheme.

3.       The WWMRC is to make decisions about the application of the fund and in 2016 recommended (which council approved) an additional $300,000 be added to the fund and a further $50,000 for each year of the life of the consent (subject to a review every three years as part of the Long Term Plan process). The current amount in the fund stands at approximately $570,000.

4.       The committee also agreed to review the original guidelines for applications to the EMEF to encourage more coordinated packages of work rather than standalone applications and establish an independent panel for assessing applications and allocating funds.

5.       Through a series of workshops, the tangata whenua members of the committee have drafted an updated Policy Manual to provide a set of eligibility criteria for potential projects, the skills required by those on the independent panel and a set of assessment criteria for projects to be assessed against.

 

Next Steps

6.       Staff to organise a workshop for the draft policy manual and a process for appointing the independent panel to be finalised by the committee.
