asset continues to meet its minimum life expectancy. A formal plan has not been documented but in practice includes the strategic drivers to provide for public safety, 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 expectations, minimise collateral damage or danger and avoid unnecessary nuisance Preventative Maintenance – Planned maintenance schedules are implemented to minimise risk and costs of premature failure; 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 stormwater assets are monitored and data communicated to automatic or manual control mechanisms. Systems are controlled to operate within pre-defined ranges and procedures are implemented to respond to detected abnormalities according to need. Incident management - Staff of the A & S department prepare and plan for managing emergency incidents; to mitigate the effects of a major storm events or system failure and return to business as usual as soon as possible. 4.3.1 Operational Management General maintenance and repairs on the stormwater infrastructure in Blenheim, Renwick, Havelock and Seddon are undertaken by the staff of the Works Operation section of the A & S Department. Works Operations repair and maintain the reticulation and provide a 24/7 call-out service. Routine maintenance schedules have been established to inspect, clean and maintain screens, gratings, channels, culverts and pump stations on the system. A full-time technician is employed to oversee the maintenance of electrical and telemetry components within the system. More specialist work is contracted out to specialist electrical, mechanical, telemetry or civil engineers. Similar work in Picton is undertaken through a term contract. The term contract was re-tendered in 2014 and awarded to the incumbent contractor for a further three years with two options to renew for two years each. The contract is managed by a dedicated MDC engineering officer. The conditions of the contract specify the operational procedures, skills of the operatives and the quality of materials and fittings to be used. Renewal of the contract is reliant upon meeting minimum key performance indicators. SCADA telemetry is installed on three pump stations at Waitohi, Picton, Dry Hills and Hardings Road. The telemetry data is returned to the engineering officers who have direct access to monitor real time data and trending of the parameters. A 24/7 standby roster is maintained to monitor the system and an automated tiered alerting system is employed to ensure system alarms are responded to. A new asset management information system was introduced in December 2014 to replace the existing Hansen asset information management system. The software will record all schedule and reactive maintenance as well as the attributes of the assets. Maintenance schedules will be programmed to automatically generate work orders for routine servicing. The maintenance Page 45
