Activity Summary: Sewerage and the Treatment and Disposal of Sewage

Activity Summary: Sewerage and the Treatment and Disposal of Sewage Activity name Activity description Sewerage and the Treatment and Disposal of Sewage The Kaipara District Council operates six community wastewater schemes for: Dargaville; Glinks Gully; Kaiwaka; Te Kopuru; Mangawhai; and Maungaturoto. The Sewerage and the Treatment and Disposal of Sewage Activity focuses on protecting public and environmental health by collecting and treating wastewater prior to release into receiving environments. Council owns and maintains the wastewater service network covering: Collection and transfer of wastewater (reticulation); Pump station facilities; Treatment and storage of wastewater; and Discharge of treated wastewater into surrounding environments. Council s Sewerage and the Treatment and Disposal of Sewage Activity includes other responsibilities through their professional and physical works contracts. Council undertakes the following: Asset Management; Customer Services; Treatment Plant Operations and Maintenance; Capital and Refurbishment Programmes; and Consent Monitoring and Compliance.

2 Activity Profile: Sewerage and the Treatment and Disposal of Sewage Activity name Sewerage and the Treatment and Disposal of Sewage Level of Service Legal compliance with all Resource Consents for discharges into the environment from Council systems. The exception, provided for in the consent, is severe weather events and power failure; Services to customers from the six community wastewater schemes will be reliable and dependable; Extension of connections, disconnections to Council systems and exits from a scheme will be progressed where a business case shows benefits are in line with costs; We comply with Resource Consents except for Kaiwaka and Te Kopuru. Desludging of ponds will assist with compliance in the future and assist to avoid or mitigate any breaches of consent conditions; An extension of reticulation in Mangawhai is likely to be necessary to realise the full benefit from the investment already made; and Improvements are needed to the Asset Management Plan (AMP) to understand asset condition better and have an improved investment programme. Contribution to Community Outcomes Council wants to work with the people in Kaipara to make it a place where it s easy to live. When it s easy, it will be easy to do business here, easy to join in and easy to enjoy nature. The key issue for easy in this activity is affordability. A number of the schemes may become unaffordable in the future due to the level of renewals required to fix aging assets, and the declining population in some villages who need to pay for the work. To address this, Council is considering alternate ways of supplying this service to declining communities with aging infrastructure. Activity delivery model The preferred option is Core Activity In-house. Undertaking Core Activity In-house enables Council to take control of the professional services currently provided externally. There would be significant change from what we currently do, meaning: Management and Contract efficiencies Direct professional services provided internally Ownership of the asset. Page 2 of 13

Activity Profile: Sewerage and the Treatment and Disposal of Sewage 3 Activity name Sewerage and the Treatment and Disposal of Sewage The Kaipara District Council s Sewerage and the Treatment and Disposal of Sewage Activity functions through two key contracts whilst maintaining some asset management responsibilities in-house through Council s General Manager Infrastructure and Water Services Manager. The key external Contracts are: Operations and maintenance; carried out through a single multi-year Contract (Contract 527) that covers: o Day-to-day operations, inspections and planning o Responsive maintenance o Planned maintenance o Renewals (as requested) o Capital upgrades (as requested) o Resource consent reporting o Financial reporting o Asset data collection. The Operations Contract delivers the Lifecycle Management outcomes on a day-to-day basis. Professional Services; delivered through a separate multi-year Contract (Contract 666) that covers capital works. Service level issues The schemes in the west are getting old and require investment, especially in the aged pipe network. It may be unaffordable to continue to provide services with the current aging plant/pipes to declining communities with old schemes. Communities most affected include Te Kopuru and Glinks Gully. The current levels of service will be maintained for the next 3 years whilst further assessment of the infrastructure is undertaken. The trend towards higher and higher environmental standards of discharges may incur increased costs that communities will struggle to pay for. The MCWWS has unused plant capacity. Investigation is required to assess whether it is affordable to extend disposal and connection reticulation to use the full capacity of the plant. An Advisory Panel comprising six community members and two Commissioners have been appointed to consider if the reticulation network and disposal capacity should be extended to use more of the capacity of the plant. The business case for extension (or otherwise) will not be completed in time for inclusion in the Long Page 3 of 13

Activity Profile: Sewerage and the Treatment and Disposal of Sewage 4 Activity name Sewerage and the Treatment and Disposal of Sewage Term Plan for 2015/2025. To prepare for a decision that the extension should proceed, a budget allowance has been included in years 4-10 totalling $2.7m. This should not be read as a decision to extend. This is still to be decided. Risks The biggest risk is scheme failure because of the lack of investment in pipe renewals in the schemes reaching the end of their asset life. Funding source and rationale Funding: The sources of funding are from General Rates, Uniform Annual General Charges and ed Rates. ed Rates form the largest proportion of funding. Rationale: There has been a falling ratio from around 78% ed Rate in 2013/2014 to 68% ed Rate in 2015/2016. Those that use the system pay the greater costs that relate to the operation of the system. The increasing community share reflects that the entire community benefits environmentally through sewerage systems that function in accordance with their Resource Consents and that costsharing on this basis is appropriate. Key policy and statutory related cost drivers Local Government Act 2002 Resource Management Act 1991 Health Act 1956 Regional Policy Statement Regional Water and Soil Plan Regional Coastal Plan New Zealand Coastal Policy Statement National Policy Statement for Freshwater Management Wastewater Drainage Bylaw 2009 Trade Waste Bylaw 2009 The cost drivers are the necessary investment in capital plant, and compliance with ever-increasing environmental standards.

Sewerage and the Treatment and Disposal of Sewage Significant Negative Effects Possible negative effects of this activity could include system failure or pipeline breakages that result in contamination of public waterways which results in an environmental or public health risk. Overflows of sewerage to waterways during heavy rainfall events may also be a negative effect. Council s Wastewater Asset Management Plan describes its wastewater assets and details the practices used to manage those assets which helps to reduce possible negative effects and risks; Overflows from the wastewater pumping stations to river/water bodies may result in the Northland Regional Council issuing an infringement notice; Council has installed a warning system at critical wastewater pumping stations to warn its operations staff before they overflow; and Failure of wastewater treatment plant in meeting the resource consent parameters may result in the Northland Regional Council issuing an infringement notice. Council measures performance of its wastewater treatment plants on a regular basis to monitor the treatment processes and ensuring compliance with the resource consents.
