The Awatere Water Users Group is currently actively involved in seeking an economically acceptable solution to the water treatment issue. Early approaches have been made to the resident’s association in Renwick and a Community Consultation Group in Picton on water demand management strategies for the two towns. Not all projects are directly presented to public consultative forum for discussion. Vested Assets - The Council will accept ownership of assets constructed by private developers. These are normally extensions to the reticulation to serve land development sub- division. The assets will only be accepted if they are designed and constructed to rigorous standards. The process is supervised by the Infrastructure Project Engineer and subject to his final approval of quality. Purchased Assets - The Council has previously purchased water supply assets or taken them over by agreement from private owners. There are no plans for similar purchases in the future however. 4.5.1 Summary of Future Costs The water supply capital works programme budget has been adjusted to meet the overall Council rating target. The delay of major capital expenditure has been one of the techniques used to reduce the overall Council expenditure and balance the budget since 2012. Deferment is only undertaken where the consequences of that are not severe whether they be environmental or economic. The capital budget is shown in Appendix 3 – Capital Budget 2015-18. The budget is based on engineer’s estimates or outline cost estimates and include contract costs, design, supervision, land purchase and access costs and a contingency percentage. The estimates are considered moderately to highly accurate. The programme has traditionally been optimistic as it assumes the optimum progression through the feasibility, design, public consultation, consent and approval process. This is a conservative, but necessary, assumption to ensure that the funding is in place for the earliest possible start, but project progression is seldom straight-forward. Table 12 shows the distribution of costs between growth, level of service and renewal for the major capital schemes proposed over the next three years.
