Figure 19 Customer Service Requests – Water Supply 4.3.2 Operational Management General maintenance and repairs on the water supply system in Blenheim, Renwick, Havelock and Wairau Valley are undertaken by the staff of the Works Operation section of the A & S Department. Similar work in Picton and Awatere is undertaken by a term contract in each of the areas. 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. Works Operations and contract labour repair and maintain the reticulation and provide a 24/7 call-out service. Routine maintenance of the treatment plant and pumps is undertaken by the engineering officers whilst more specialist work is contracted out. 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. Page 64
