Item 8: Infrastructure Fees and Charges 2018-19

 

Works and Infrastructure Committee

22 May 2018

 

 

REPORT R9074

Infrastructure Fees and Charges 2018-19

     

 

1.       Purpose of Report

1.1      To advise the Committee and approve fees and charges for Utilities (water), Roading and Solid Waste services for the 2018/19 financial year.

 

 

2.       Recommendation

That the Works and Infrastructure Committee

Receives the report Infrastructure Fees and Charges 2018-19 (R9074) and its attachment (A1918450); and

Approves the proposed fees and charges as per attachment A1918450 of Report R9074 effective 1 July 2018.

 

 

 

3.       Background

3.1      Fees and Charges are reviewed annually and either adjusted in line with the Consumer Price Index (CPI) or changed to reflect any changes in process and/or costs incurred to Council. This report proposes some increases to Infrastructure fees and charges for 3 areas (Utilities, Roading and Solid Waste).

3.2      Officers currently have delegations to set fees and charges but officers are of the view that approval via the relevant committee is appropriate.

4.       Discussion

4.1      Proposed Fees and Charges for Utilities (water) are listed in Table 1 of Attachment 1. A CPI adjustment of 1.6% is proposed across the board as no CPI adjustment was made last year.

4.2      Proposed Fees and Charges for Roading are listed in Table 2 of Attachment 1. A CPI adjustment of 1.6% across the board is proposed. A new category for Corridor Access Requests (CAR’s) relating to Emergency Work has been created. This charge reflects the cost of retrospective approval and reinstatement inspection.

4.1      Proposed Fees and Charges for Solid Waste at the transfer station are listed in Table 3 of Attachment 1. A CPI adjustment of 1.6% across the board is proposed. Two additional changes in transfer station fees and charges are proposed:

4.1.1   An increase in the fee to commercial operators for disposing of hard fill at the Pascoe Street transfer station. Currently it is less expensive for commercial operators to take hard fill to the transfer station than to the regional landfill. Council incurs cartage costs from Pascoe Street to York Valley landfill and so the increased fee has been calculated to incentivise commercial operators to take hard fill directly to the regional landfill at York Valley.

4.1.2   The phasing out of accepting green waste at the Pascoe Street transfer station is in line with the approved 2018-21 Solid Waste Asset Management Plan, and the Joint Waste Management and Minimisation Plan. It is proposed to increase Green waste fees to $35 per m3 from 1 July 2018 with the aim to phase out this service at the transfer station by 30 June 2019. The strategy is based on the premise that our customers will realise that the service can be more economically accessed through commercial service providers.

4.2      Subject to approval by this Committee, all users will be given a minimum 30 days’ notice of the proposed changes prior to implementation.

5.       Options

5.1      Option 1 Approve the proposed charges effective 1 July 2018. This is the recommended option.

5.2      Option 2 Do not approve the proposed charges.

 

6.       Conclusion

6.1      Officers recommend that the Works and Infrastructure Committee approve the charges as set out in Attachment 1 of this report.

Attachment 1:  A1918450 Proposed Fees and Charges Infrastructure Operations 2018-19

 

Important considerations for decision making

1.   Fit with Purpose of Local Government

Annual review of fees and charges enables Council to meet the current and future needs of communities for good-quality local infrastructure, local public services, in a way that is most cost-effective for households and businesses.

2.   Consistency with Community Outcomes and Council Policy

Approving amended fees and charges enables Council to carry out activity that is aligned with the community outcome “our infrastructure is efficient, cost effective and meets current and future needs”.

3.   Risk

Fees and Charges are reviewed annually and either adjusted in line with the Consumer Price Index or changed to reflect any changes in process and/or costs incurred to Council. If proposed changes are not approved the income generated from fees and charges may not cover actual costs incurred and result in a financial shortfall.

4.   Financial impact

The fees and charges income is included in Council’s Long Term Plan. 

5.   Degree of significance and level of engagement

The recommendations outlined in the report are not considered significant in terms of Council’s Significance Policy. No Formal consultation has occurred with regards to the proposal in this report

6.   Inclusion of Māori in the decision making process

Maori have not been consulted

7.  Delegations

The Committee has powers:

“To perform all functions, powers and duties relating to the areas of responsibility conferred on Council by relevant legislation and not otherwise delegated to officers”.  

Currently officers have delegated authority to set fees and charges, however officers are of the view that approval via relevant committee is appropriate.

Item 9: Havelock North Drinking Water Government Inquiry

 

Works and Infrastructure Committee

22 May 2018

 

 

REPORT R8851

Havelock North Drinking Water Government Inquiry

     

 

1.       Purpose of Report

1.1      To provide the Committee with an opportunity to consider the stage 2 report from the Havelock North Drinking Water Government Inquiry.

2.       Summary

2.1      In August 2016, there was a major outbreak of campylobacteriosis in Havelock North. Investigations traced the source to the drinking water supply administered by the Hastings District Council.

2.2      In September 2016 the Government established an Inquiry to establish the cause of the outbreak and make recommendations for prevention of a similar event in the future.

2.3      The Inquiry was in two stages. The Stage 1 report was issued in May 2017 and covered the background, established the likely cause and assessed the conduct of those responsible for providing safe drinking water to Havelock North. The Stage 2 report was released in December 2017 and focused on improving the safety of drinking water in New Zealand, lessons to be learned from the Havelock North outbreak, and any changes which should be made to the drinking water supply environment to achieve the goal of reliably safe drinking water. Copies of both reports are available in the Councillors Lounge or from the Department of Internal Affairs website:  www.dia.govt.nz/Government-Inquiry-Into-Havelock-North-Drinking-Water.

2.4      The Stage 1 report identified short-comings with the parties directly involved in the water supply being the Hastings District Council, the Hawkes Bay Regional Council and the Hawkes Bay District Health Board.

2.5      The Stage 2 report made suggestions for improvement in the national drinking water supply environment, particularly the following:

·    Dis-establishment of the current Ministry of Health Unit overseeing drinking water regulation

·    Establishment of an independent water regulator

·    Establishment of 6 principles to guide water management in NZ

·    Mandatory multi-barrier treatment of public water supplies

·    Removal of secure groundwater status

·    Requirement for a residual disinfectant in the network

·    Significant changes to the regulations; water safety plan regime; the National Environmental Standard for Sources of Human Drinking Water and the Drinking Water Assessors regime.

           The report also has a section with recommendations that the Government look at aggregating supplies of water.

 

 

3.       Recommendation

That the Works and Infrastructure Committee

Receives the report Havelock North Drinking Water Government Inquiry  (R8851); and

Notes the findings of the Havelock North Drinking Water Government Inquiry and the likelihood of future change in the drinking water supplier environment.

 

 

4.       Background

4.1      The Havelock North water supply is drawn from sub-surface bores and was untreated at the time of the contamination. The most probable source of the contamination was found to be contaminated surface water from animals grazing a paddock adjacent to one of the water bores, leaching into the aquifer that supplied a drinking water bore.

4.2      Approximately 5,500 residents became ill from the contaminated drinking water and it is possible that the water contributed to the deaths of four people.

5.       Discussion

5.1      The Stage 1 Inquiry reviewed the performance of the key bodies that held the responsibility for providing drinking water to Havelock North. This resulted in the following finding:

“This Inquiry has found that several of the parties with responsibility for the water supply regime for Havelock North (in particular the District Council, DWAs (Drinking Water Assessors) and Hawke’s Bay Regional Council (“Regional Council”)) failed to adhere to the high levels of care and diligence necessary to protect public health and to avoid outbreaks of serious illness.”

5.2      An interim measures report was released in December 2016 which recommended, among other things, the establishment of a closer working relationship between the parties through a Joint Working Group, extensive ongoing monitoring of the water supply and chlorination of the water.

5.3      The Stage 2 Inquiry followed on directly from Stage 1 and had a far-ranging brief to look into water supply arrangements throughout the country.

5.4      Fifty one recommendations were made by the Inquiry as part of the Stage 2 report. These broadly fall into the following categories:

·    Administrative.

Promulgate six principles of drinking water safety

Review NZ standards, Health Act and Drinking Water standards and abolish ‘secure’ classification for bores

Establish an independent drinking water regulator

Ministry of Health to improve compliance with existing regulations

Amend the Resource Management Act to improve water source protection

Accelerate the review of the National Environmental Standard for Sources of Human Drinking Water.

·    Operational.

Encourage/mandate treatment (chlorination) of water supplies

Encourage formation of joint working groups to oversee drinking water safety throughout the country

Introduce licensing and qualification requirements for suppliers and operators

Create dedicated and aggregated drinking water suppliers,

Improve the testing and laboratories regime

Prohibit high risk bore construction techniques.

5.5      The recommendations largely rely on Central Government to enact legislation before they can be implemented. Some progress on these is likely during 2018-19. Those recommendations that encourage treatment of drinking water and improving compliance with existing regulations have already been actioned by the Ministry of Health.

Nelson’s Water Supply

5.6      The Nelson City Council water supply is currently in a better position than many supplies in that the raw water is not sourced from bores and all water from the river sources is currently subject to a double barrier of ultra-filtration membranes and chlorination.

5.7      In terms of the Council risk analysis procedure a failure of the integrity of the treatment process is assessed as follows:

·    Consequences (Impact) - Multiple fatalities of workers or public – Extreme (score 5).

·    Likelihood – Rare (score 1) given the current treatment process.

·    Risk = Consequences x Likelihood = 5 x 1 =5 (Medium rating).

·    The Residual Risk Tolerance appropriate for this result assesses the risk as ‘Normally tolerable’ and requires frequent review to look for opportunities to further reduce risk where practicable.

5.8      In order to respond to the above need to reduce the risk Council also has a rigorous testing regime that incorporates the following:

·    Ten sites across the City network are tested weekly. All are tested for chlorine residual levels and five are tested for bacteria. The sites chosen vary on a thirteen week cycle.

·    Fifteen reservoirs in the City are tested weekly for a range of factors including chlorine residual levels. Five are also tested for bacteria.

·    Bacterial testing is carried out at the water treatment plant and the Stoke High Level reservoir twice a month.

·    There are continuous chlorine analysers at Monaco View and Todds Bush that allow 24 hour monitoring of chlorine content in the water at the outer edges of the reticulation. The water treatment plant also has two continuous analysers to monitor the process before water is introduced to the network.

5.9      Tasman District Council (TDC) supplies water to the residential area in south Nelson adjacent to Champion Road and Hill Street North (and to Richmond) from underground bores and then treat this water with ultra-violet light prior to supplying the network. While this form of treatment does not provide residual disinfection in the drinking water, TDC do have chlorine dosing equipment available for emergencies or if testing identifies the presence of E.Coli in the reticulation. 

6.       Options

6.1      The report is advisory only and does not require the evaluation of options.

 

7.       Conclusion

7.1      The contamination incident in Havelock North is likely to lead to significant change in the drinking water supply environment.

7.2      The Nelson City Council supply is currently well positioned to comply with any treatment requirements that may arise from future changes to legislation.

Important considerations for decision making

1.   Fit with Purpose of Local Government

Council is the major provider of drinking water to the city and as such it meets the current and future needs of the community for a water supply.

2.   Consistency with Community Outcomes and Council Policy

Provision of a good quality drinking water supply meets Council’s Community Outcome ‘Our infrastructure is efficient, cost effective and meets current and future needs’

3.   Risk

The report is advisory only and there are no recommendations for change to current operating procedures. There is no change to the current risk profile.

4.   Financial impact

The report is advisory only and there are no immediate financial implications.

5.   Degree of significance and level of engagement

This matter is of high significance because Council is the primary supplier of drinking water to the community. The report is advisory only and no community consultation is required at this stage.

6.   Inclusion of Māori in the decision making process

Māori have not been involved in the development of the report.

7.   Delegations

The Works and Infrastructure Committee has the responsibility for considering matters relating to the water supply.
