Abstract
The Water Supply Master Plan for Rarotonga is a sectoral policy, covering the period of 3 years between 2013 and 2016. This Master Plan sets out strategies to implement the Government of the Cook Islands policy of delivering potable water, reliably, to all properties connected to the existing water supply network, by 2015/2016.
The Master Plan aims at providing immediate tangible benefits for the local community, such as providing a reliable water source to all connected properties; providing safe drinking water through reliable treatment facilities to prevent water-borne diseases; strengthening the governance of the water network. The Master Plan addresses the deficiencies in the water supply network caused by deterioration of the existing network, changes in population growth and legislation and determines appropriate solutions to meet the current and future demands. Based on this, the first priority is to increase the reliability of supply which will be achieved through the construction of the storage reservoirs at the intake sites. The trunkmain construction project will be carried out in accordance with the hydraulic modelling for the recommended upgrade of the trunkmain size. This hydraulic modelling will also include a review of the use of groundwater resources and updated system demand.
Water treatment plans will be developed to provide a safe potable water supply. In order to provide and maintain drinking water quality in the Rarotonga water supply system, a multi-barrier approach will be implemented to remove contaminants from the water source and maintain quality after treatment and prior to delivery to consumers. The leakage control measures will be taken during the design and construction of the new water supply system, targeting the areas of highest leakage and those areas serviced from the new reservoirs which will be brought on line first. Furthermore, an information and awareness programme will be carried out on water loss through private leakage (internal and external) and water efficiency measures.
