6            Reports

 

6.1        Events Centre Activities

 

1.               Purpose

For the Committee to be updated on Carterton Events Centre and Council Facilities Management.

2.               Significance

The matters for decision in this report are not considered to be of significance under the Significance and Engagement Policy.

3.               EVENTS CENTRE

While the past few months have been challenging on the live events front, there are encouraging signs that activity is picking up and the rest of the year promises to be busy and eventful.  From June until the end of the year, we are currently fully booked for all Saturday evening slots.

Since the last report we’ve delivered a chamber musical, Love Linda, and the inaugural WaiTech virtual reality and gaming event.  We’ve also hosted a range of workshops and business training events across our spaces, despite the lull in larger scale ticketed events in the auditorium. We have several new regular bookings including the Open Polytechnic, Te Aho Te Kura Pounamu, and Solid Ground Church, and while they lack the glamour of one-off ticketed events, they provide consistent income which allows us to ride out the dips in other programming.

June will see the Events Centre humming with events once again:  The NZSO, The Big Bike Film Night, the finale of Talent Wairarapa, The Wairarapa Times Age Sports Awards, The Glow Show, and finally bringing the region Yes Yes Yes, a work about consent and relationships that’s twice been postponed due to Covid.

The team is also working in conjunction with the Community Development team to assist in the delivery of upcoming community events:  The first Daffodil Festival since 2019, a range of events for Matariki weekend, and after having to cancel last year we are excited to be working with Orchestra Wellington to deliver Classical in Carterton.

In May Jenni Hall attended the EVANZ mid-year conference in Nelson, focussing on Audience Development.  As a part of our refreshed strategy, we are looking at ways to extend our audience base and other subscription models in order to encourage patron loyalty, repeat attendance and create marketing opportunities. We are also looking at more robust reporting on productions, audiences, and room bookings to better inform our decision-making moving forward.

There have been some changes in the team with the resignation of Brett Stringer after ten years’ service at the Carterton District Council. He will be missed, and we wish him all the best with his future endeavours.  We are taking the opportunity to refresh the role description and look at the team to determine where we most need resource in the coming months as events ramp up.  It is particularly important to ensure that we have the technical depth within the team to cover absences and leave when required, and still deliver top tier events.

4.               SALES AND MARKETING

The move to the orange traffic light setting and the lifting of gathering restrictions has meant much more than just people on seats. People are more excited to come out, although across the industry there is a trend for patrons to buy tickets at the last minute, rather than booking ahead. For example, 20% of the tickets sold to the Waitech event were sold on the day.

Since our last report things have been on the up. The move to the orange traffic light setting and the lifting of gathering restrictions has meant much more than just bums on seats. People are more excited to come out, although across the industry there is a trend for patrons to buy tickets at the last minute, rather than booking ahead. For example, 20% of the tickets sold to the Waitech event were sold on the day.

In terms of our social channels, while there hasn’t been lots to post about, our Instagram statistics have remained stable, and we’ve had some good engagement through Facebook.

3.2             Liner Repair Strategy Update

Remedial work began after the Tonkin and Taylor’s (T&T’s) Engineer’s report was received – “Carterton WWTP Reservoir Construction Contract 02/2018 – Assessment of Defect on Reservoir HDPE Liner” (Attachment 1).

Work included repairing liners where scratches were more than 10 percent of the total liner depth.  When repairs to reservoir one were completed, this allowed for the filling of reservoir one to commence (9  May 2022). This marked a significant milestone in the project (see figure 1 – Reservoir 1 Filling).

In order to ensure dam safety requirements are met, a staged approach to fill each reservoir is being taken. Reservoir filling is weather dependent as the colder mornings are needed to ensure the liner is not wrinkled once the filling begins. Repairs to reservoirs two and three will begin in June 2022.

Figure 1 – Reservior Filling

Figure 2 – Reservior’s over view.

3.2             Stage 3 – Pipelines and Pumps

The Pump Station headworks mechanical installation was completed and electrical work 90% completed (Figure 3 - Headworks).

Figure 3 – Headworks

 

3.3           Mangatārere Stream Diffuser Outfall

The construction of the Diffuser is complete (Figure 4 – Stream Diffuser and outfall pipeline).  The team has started with the construction of the Outfall pipeline between the Diffuser and the Pump station. The team is making good progress by utilising the mild weather conditions through early May 2022.

Figure 4 – Stream diffuser location

3.4            Financial impacts

Now we have the repair methodology for the liner, we have refreshed our cost forecast for the overall project.  This is included below. 

The forecast reflects our current estimate of the project outcome, including the cost of remedial repair of the three reservoir liners.  The forecast is net of anticipated recoveries from CHB Earthworks Ltd. 

Financial Forecast

Project
Name

Total Cost of Project including forecast

Total Project Budget

Stages One and Two

8,080,125

 

Stage Three

5,135,175

 

Contingency

200,000

 

 Total

14,310,557

14,612,447



As the programme of work progresses CDC will continue to monitor the forecast and report regularly to Council, especially over the winter period.  The recovery process against CHB Earthworks Limited will begin once remedial repairs have been undertaken and Stage 2 reaches practical completion.

Further information and detail on Stage 3 costs will be presented at the 29 June 2022 Ordinary Council meeting.

3.5            Resource Consent

      Historical compliance

Recent compliance reports have indicated a number of non-compliances for both years. The non-compliances related to late documentation and missing data.

·    The issues identified have been remedied with an improved data collection process (related to implementation of the Water Outlook programme), and reminders for dates.

·    In addition, a new control system is planned with the storage reservoirs.

                  Future Risks

The consent condition allowing the regular winter discharge to stream from the existing weir by the UV container expires on 31 December 2022 and is not able to be extended. After this time this weir can only be used in emergency situations, with the transfer of the discharge to stream from the new diffuser location (shown in Figure 4 above).

Once this discharge is active, the operating requirements change significantly, with discharges to Mangatārere stream over 3x median flow, from the current 0.5x median flow. This will be managed with the new storage reservoirs and land discharge areas.

Risks for compliance are:

·    Bringing sufficient land discharge areas into service in a timely manner

·    Repairs to the storage reservoirs being delayed

·    Water quality from the new reservoirs (Programme of twelve months testing will begin on 1 January 2023)

3.6             Community Engagement – Wastewater Treatment Advisory Group

A requirement of the consent is at least an annual meeting of the Wastewater Treatment Advisory group. This is a group of interested community groups, Iwi, public health, and Council members.

There have been four meetings over a nine month period to discuss the next area for irrigation and options. In the last two meetings a multi-criteria assessment (MCA) tool was developed to assist the group to be able to compare different options and provide a balanced weighting of the different views of the group. At the last meeting, it was agreed to use the tool to consider the following options:

1.    Cut and Carry grass harvesting, as per the original concept

2.    Cut and Carry pole nursery, similar to Akura nursery

3.    Short rotation coppice willow plantation


 

Information has been provided to all advisory group members on the three options for them to evaluate and complete the MCA.  A consolidation of the individual advisory group MCA assessments will be prepared and presented at the next advisory group meeting on the 10 June 2022 at the Carterton Events Centre. The outcome of this meeting will provide a recommended option for the additional irrigation area.

As these conversations have progressed there have been differing opinions between some group members. Notably, questions have been raised about the Greater Wellington Regional Council proposal for a poplar and willow pole nursery from proponents who favour alternative nursery options.  Because of criticism and perceived conflicts of interest, Greater Wellington Regional Council has decided not to participate further in the MCA decision.  GWRC will continue to provide advice to the advisory group including research and technical data where this is available.

 

4.               Recommendation

That the Committee:

1.         Receives the report.

Infrastructure and Services Committee Meeting Agenda

1 June 2022

 

 

6.3        Ruamāhanga Roads Report

 

1.               Purpose

For the Committee to be updated on Ruamāhanga Roads activities.

2.               Significance

The matters for decision in this report are not considered to be of significance under the Significance and Engagement Policy.

3.               Overall expenditure and forEcast

Opex and Capex combined expenditure at end of April 2022 is 71% with the forecast for the financial year indicating a 10% underspend. Even though there is an underspend, all major works for the year have been completed. The underspend may be carried forward into the next financial year. The forecasted underspend is a result of a combination of factors such as:

·    The impact of Covid-19 on resources.

·    Recent weather events on SWDC.

·    Design and construction efficiencies.

 

4.               OPEX expenditure

Expenditure reports below are set against the Waka Kotahi budget allocations and are for the period of works completed between 01/07/2021 to 31/04/2022 which equates to 83% of the elapsed time for this financial year.

4.1             Sealed road pavement maintenance

Sealed Road pavement maintenance was 79% spend in relation to Waka Kotahi NZTA budgets allocation.

The focus is on completing the final pre-seal repairs ahead of the 2022/2023 sealing programme, and on maintaining a safe network for road users.

4.2             Unsealed road maintenance

Unsealed road maintenance was 151% spend in relation to the Waka Kotahi NZTA budgets allocation.

4.3             Drainage maintenance

Drainage Maintenance was 100% spend in relation to the Waka Kotahi NZTA budgets allocation.

 

 

4.4             Structures maintenance

Structures maintenance was 58% spend in relation to the Waka Kotahi NZTA budgets. Even though the budget is small, works including bridge inspections are being completed along with minor works on bridges and retaining walls.

Works identified through the 2020/2021 inspections will make up the new year’s programme with general inspections carried out every two years and principal inspections carried out every six years.

4.5             Environmental maintenance

Environmental Maintenance was 112% spend in relation to Waka Kotahi NZTA budgets.

4.6             Traffic services

Traffic services was 17% spend in relation to the Waka Kotahi NZTA budgets, the annual road marking is programmed for May and equates to 75% of the budget spend.

Sign inspections and asset data updating, and minor streetlight maintenance are continuing.

4.7             Footpath maintenance

Footpath maintenance is at 59% of budget. Our forecast indicates that we will overspend in this category by the end of the financial year. Footpath renewals planned for the rest of the financial year includes:

·    Wakelin Street

·    Mckenzie Terrace

·    Moreton Road

5.               CaPEX expenditure

Expenditure reports are again set against the Waka Kotahi budget allocations.

5.1             Unsealed Road Metaling

Unsealed Road Metaling was 27% spend in relation to the Waka Kotahi NZTA budget allocation. Heavy application of aggregate is programmed through May and June when conditions were more suited to the supply and placing of layers on unsealed roads.

5.2             Sealed road resurfacing

Even though we only delivered 94% of the budget we have deferred the remainder of the program until next season. The deferral comes because of a combination of weather constraints and Kiwi Rail liaison. Excluding the rehabilitation sites, we completed a total of 76 233m² for the season.


 

 

5.3             Drainage renewals

Drainage renewals were 52% spent in relation to the Waka Kotahi NZTA budget allocation. Culverts and Kerb and Channel are programmed to be renewed where their condition affects the pavement and road user’s safety.

5.4             Pavement rehabilitation

We have completed the programme for the year and are currently in the process of identifying next year’s priorities.

·    Cornwall road RP 4.91 to 5.296 - Completed

·    Gladstone road RP 3.205 to 3.441 - Completed

·    Gladstone road RP 4.985 to 5.306 – Completed

5.5             Traffic service renewal

Traffic Service Renewals are at 86% spend in relation to the Waka Kotahi NZTA budget allocation. Signs are being renewed when and where possible.

5.6             Low-Cost Low Risk

Carriageway widening on Hughes Line to accommodate SH2 detours has started in January 2022 and is 90% complete. The outstanding work is the installation of a new pre-cast concrete box culvert. The outstanding pre-cast concrete box culvert has been delivered to Fulton Hogan who is programming the installation.

6.               Speed review

Tonkin and Taylor has been engaged to develop a Speed management plan for both CDC and SWDC. The plan will be developed in accordance with Waka Kotahi NZ Transport Agency’s Speed Management Guide. We anticipate a draft plan to be delivered by the end of June 2022.

The plan will identify principles and priorities which will lead into proposals. Once the proposals are finalised we plan to consult through an online interactive portal.

7.               Enaki Stream Realignment

Over time the Enaki stream realigned itself through flood debris build-up. The new alignment posed a future risk to Belvedere Road and potentially the bridge. Through collaboration with GWRC and landowners we have realigned Enaki stream back to its 1999 alignment.

  

 

 

 

Photos taken 21 May 2022 after decent rain.

 

During high flow it would appear as if the stream was preferring the 1999 course with only a small volume of water using the old (Feb 2022) course. Therefore, the risk to Belvedere Road has been managed to a satisfactory level. 

 

8.               Recommendation

6.4        Wastewater and Solid Waste

 

1.               Purpose

To update the Committee on Wastewater and Solid Waste.

2.               Significance

The matters for decision in this report are not considered to be of significance under the Significance and Engagement Policy.

3.               Purpose

To update the Committee on Wastewater and Solid Waste.

4.               Significance

The matters for decision in this report are not considered to be of significance under the Significance and Engagement Policy.

5.               WASTEWATER TREATMENT PLANT

April and May have been very unseasonable this year which has impacted on our ability to discharge.

The Mangatārere Stream has been in low flow, which has hindered our ability to discharge to Water, however we have been fortunate that the water table and moisture levels have also been low to enable discharge to land to continue past the ‘normal’ operating season.

So, by combining low volumes of discharge to stream (when able) and discharge to land we have been able to manage the oxidation pond levels.

Inflows have been steady in the last 2 months, averaging around 35l/s

                         Graph 1 - showing Inflows into the WWTP


 

 

The insurance claim for the Damaged Pivot Irrigator span has been accepted, and we are waiting on confirmation of payment before proceeding with the repairs.

Part of this financial years Capex has been allocated to upgrade the sprinkler heads which will be completed in conjunction with the rebuild of the last span. The new sprinkler heads will allow better disbursement of the wastewater and therefore reduce pooling on the lower areas of the irrigation field.

Network

The network has also had low flows with the dry weather.

Projects

Existing Plant Processes

We have engaged Sorted Water Solutions to undertake an options report to improve the way the plant is operated through better balancing of pond levels. The report will take existing infrastructure and desired functionality into consideration.

Monitoring the Network Flows

The new monitoring devices to monitor flows and surcharging have been purchased. The devices are programmed for installation in July 2022. These devices will allow us to observe trends in the network. Monitoring data will inform forward works planning.

6.               Solid Waste

Transfer Station

CDC and Earthcare are in the process of changing the layout for the drop off locations of household recycling goods, paint, oil collection and steel.

The large shed has been emptied ready for conversion to the recycling area for paper, plastics, and light weight household recycling. This will provide cover from the weather for the public while dropping off recycling and stop a large percentage of goods being blown around the site. This shed also has a concrete floor allowing the staff to sweep the area to keep clear of debris.

6.5        Water Supply

 

1.               Purpose

To inform the Committee about the activities of the Water Treatment Plant’s (WTP’s) operations and work carried out by the reticulation 3 waters team.

2.               Significance

The matters for decision in this report are not considered to be of significance under the Significance and Engagement Policy.

3.               OPERATIONAL

Treatment Plants

When the weather permits, we have been supplying the reticulation network from the Kaipitangata WTP in order to allow for the changeover work at Frederick St to proceed.

Water restrictions have been removed due to low demand.

Compliance

A public notice will be placed on 25 May 2022 to inform the community that CDC is now seeking applications from 3 waters contractors to be included on its list of approved contractors.

After 30 June 2022, all contractors who either work on the Council network or who construct three waters infrastructure to be vested into Council, must be approved. This requirement is a mechanism in CDC’s Water Safety Plan for the keeping our Water Supply Network secure. The Water Safety plan is a requirement for compliance with Taumata Arowai.

The communications team is developing an online portal on CDC’s website which will list all approved contractors. This will provide the public with information for approved contractors for connections or drainage.

Mid last year ERPRO was engaged to draft a new Water Safety Plan (WSP). The WSP is a live document that must be updated with any changes to the WTP’s operational risks, the reticulation network, or to ensure the new Drinking Water Standards are met.

It is expected that the new Standards, Rules, Aesthetic Values, Acceptable Solutions, and some of the Network Environmental Performance Measures for registered drinking water suppliers will be adopted in June 2022, in time for the 1 July 2022 compliance year. In July 2022 the document will be uploaded into Taumata Arowai’s supplier portal (Hinekorako) after the final standards have been issued.

The WSP is required to be submitted by November 2022.

Projects

Upgrade of Frederick St Water Treatment Plant

The Fredrick St Upgrade is in its final stage - Treatment. This stage is inclusive of programming for the new dosing pumps and the new pipework installation for the 2nd UV.

Operations

The Waters Team have been busy with water service requests and new connections.

6.6        Mains Renewals

 

1.               Purpose

To update the Committee on the Mains Renewals.

2.               Significance

The matters for decision in this report are not considered to be of significance under the Significance and Engagement Policy.

3.               DISCUSSION

2.1 Dalefield wastewater main

The wastewater main renewal on Dalefield Road is now 95% complete. In the final stages of this project we are working near SH2. Therefore, a portion of the works is being completed at night-time. Weather dependent, we are likely to complete this project by the end June.

2.2 Wastewater main bursting

The next wastewater main bursting section in our program is from Rexwood to Costley Street. These old pipelines head south past the end of Clifton Avenue and drain into the Costley Street network. This will be a complex process which is likely to take more than six months and will be undertaken in stages (between manholes and through private properties).

2.3 Water main from Potable Water storage tanks to Frederic Street treatment plant

This project is considered phase 3 of the wider potable water supply improvement and resilience project. Following completion of the Dalefield Road wastewater main renewal, Downer will construct the water main that will connect the new water storage tanks on Dalefield Road to the Frederick Street Treatment Plant via Lincoln Road,

2.4 Pump Station at Potable water storage tanks

This project is considered phase 4 of the wider potable water supply improvement and resilience project. This project is critical to overall functionality of the wider project and how the 4 phases work together. We are in the final stages of defining the desired operational output for the pumping system. CDC is planning to go to the market by the end of June to procure a suitable supplier for the design and build of the pump station.


 

 

2.5 Chester Road water main

The design for the Chester Road water main renewal is in its final stages. On completion of the design we will follow our procurement process to engage a suitable supplier with relevant experience, relevant skills and a good track record. Kiwirail has been notified of our project and intentions.
