2.0 WasteinfrastructureThis section provides a summary of key strategic waste facilities that currently service households andbusinesses in the Waikato district.2.1 Residual waste disposal2.1.1 Landfill disposal facilitiesThe Waste Minimisation Act 2008, in Section 7, defines a ‘disposal facility’ as:(a) a facility, including a landfill,—(i) at which waste is disposed of; and(ii) at which the waste disposed of includes household waste; and(iii) that operates, at least in part, as a business to dispose of waste; and(b) any other facility or class of facility at which waste is disposed of that is prescribed as a disposal facility.(2) In subsection (1)(a)(ii), household waste means waste from a household that is not entirely fromconstruction, renovation, or demolition of the house.With this definition, the Act has created a distinct class of landfill, the ‘disposal facility’, for those facilities thataccept household waste.In the past, landfills were lightly regulated and little engineering work was undertaken to reduce theenvironmental impact from leachate and gaseous emissions. As a result, most urban areas had their ownlandfill.Since the introduction of the Resource Management Act in 1992, most small landfills have been required toclose as they are unable to meet the necessary requirements to reduce their environmental impact. This hasled to a regionalisation of landfills, with new facilities being much more expensive to establish and operate thanpreviously.There is one landfill disposal facility within the Waikato district – North Waikato Regional Landfill (HamptonDowns landfill). This landfill receives a high proportion of waste generated within the Waikato district.Minor quantities of waste from the Waikato district may also go to other landfill disposal facilities. All of therelevant facilities are listed below.Table 1: Landfill disposal facilitiesName/operator Type Key services/wastestreamsNorth Waikato RegionalLandfill (EnviroWasteServices Ltd)MunicipalLandfillNon-hazardousresidential, commercialand industrial solid waste,primarily from Aucklandand WaikatoLocationHamptonDownsCapacity & estimatedoperational lifeConsented to 2030.Capacity to at least 2045.Estimated at 478,782tonnes per annum inAuckland Council’s wasteassessment 201112

Annual tonnagecommercially sensitiveConsidering travelling distances to Whitford and Tirohia Landfills compared to Hampton Downs, it is likely thatthe vast majority of waste disposed of to landfill is transported to Hampton Downs and this is considered themost economic disposal option for the district’s waste.2.1.2 Closed landfillsThere are a number of closed landfills for which the council has ongoing management and monitoringresponsibility. These closed landfills are in Huntly, Ngaruawahia, Raglan, Te Kauwhata and Horotiu. Thecouncil carries out regular monitoring and inspection of closed landfills to ensure that they are remediated andmanaged according to the requirements of their resource consents.Hamilton City Council also has a closed landfill near Horotiu.There are also two closed landfills in the district under private ownership – a Department of Corrections facilityat Waikeria, and a timber waste landfill in Pokeno.2.1.3 CleanfillsThe Ministry for the Environment’s Cleanfill Guidelines define cleanfill material and cleanfills as follows:“Cleanfill materialMaterial that when buried will have no adverse effect on people or the environment. Cleanfill material includesvirgin natural materials such as clay, soil and rock, and other inert materials such as concrete or brick that arefree of:• combustible, putrescible, degradable or leachable components• hazardous substances• products or materials derived from hazardous waste treatment, hazardous waste stabilisation orhazardous waste disposal practices• materials that may present a risk to human or animal health such as medical and veterinary waste,asbestos or radioactive substances• liquid waste.CleanfillA cleanfill is any landfill that accepts only cleanfill material as defined above. 5 ”The council’s policy on cleanfills is the same as that of the regional council – up to 2,500 m3 per annum is apermitted activity. Resource consent is required for any cleanfill exceeding this volume, and any fill that intendsto accept material other than clean fill. The Waikato District Plan defines cleanfill as meaning:5 Ministry for the Environment (2002) ‘A Guide to the Management of Cleanfill’s.
