The public health risks associated with the water supply are analysed in depth through the Water Safety Plan (formerly Public Health Risk Management Plans [PHRMP].) These are being developed in parallel with the upgrade of the water treatment to meet the NZDWS. The current status of the Water Safety Plans is shown in the table below. Water Safety Plan Status (as at Nov 2014) Blenheim Approved by DWA Awatere Riverlands Second draft submitted to the Drinking Water Assessors. Picton Awaiting approval Renwick First draft submitted to the Drinking Water Assessor. Awaiting Havelock comments Wairau Valley Small scheme, not yet required Table 8 Status of Water Safety Plans Council mitigates residual risk through insurance. A specialist officer with the assistance of an independent broker is contracted to advise on suitable commercial insurance. The Council are also part of the Local Authority Protection Programme (LAPP.) LAPP is a not for profit co- operative of local authorities that was established to provide mutual insurance for underground assets and other specialist structures that were hard to insure on the open market. The council insures water, wastewater and stormwater reticulation, wastewater wet-wells and flood protection structures through LAPP. Following the Canterbury earthquake sequence the council has revised its insurance policy. There were substantial increases in commercial premiums and a huge demand on the LAPP fund. The Council has accepted higher excess on damage to many assets and self-insures through emergency reserves. 4.3 Routine Operations and Maintenance Plan The operation and maintenance of the water supply system is the procedures and tasks necessary to deliver to the customers the agreed level whilst ensuring serviceability of the infrastructure to maximise its useful life expectancy. A formal plan has not been documented but would incorporate the strategic drivers of the department:- All strategies recognise the primary purpose of the water supply system is to provide a resource for public health and wellbeing. Operational Works – Routine operational works will be undertaken by suitably trained and supervised staff or contractors at sufficient intervals to ensure the efficient functioning of the system. Repairs – Reactive repairs will be assessed and undertaken in a timely fashion to minimise disruption to the service, meet the customer service standards, minimise collateral damage and avoid unnecessary water wastage Preventative Maintenance – Planned maintenance schedules will be established and implemented to minimise risk and costs of premature failure or service interruptions; promote the effective and efficient functioning of assets and optimise the whole life service potential of the infrastructure. Operational management - Operational activities are undertaken by engineering officers and technicians of the Assets and Services department under the direction of the O & M Engineer to ensure the outcomes and service standards are achieved in the most efficient and cost effective manner. System Control and Monitoring – The water supply system will be continuously monitored and a procedure implemented to respond to detected abnormalities according to need. Page 62
