Infrastructure Strategy 4. Major projects for this activity All of the key themes identified in Part One of this strategy are reflected in the water supply activity. Growth in demand for water, both for residential uses and for production (irrigation & processing water), has been steadily increasing. In particular, a predicted 25% increase in wine production willincrease demand for water. Project Title There is a need to manage future growth in demand, particularly in relation to uncertainty about future demographics andclimate change, to ensure the water sources remain at sustainable levels for all usrs.e Levels of service have been set to ensure tap water from all Council supplies is safe for drinking. Building and running the High Street 2025/26 $3.5M 100% treatment plants present affordability issues for small communities. - - Bridge Much of the water reticulation infrastructure was installed during the ‘baby boom’ Replacement growth periods in the middle of the 20 century. These pipes will reach the end of theirth useful life over the next 30 years. The pipe materials used at that time are less resistant to ground shaking during earthquakesthan the materials we have been using more recently. Managing an efficient and effective renewals programme that improves theresilience of the networks will be a key challenge Water Supply The following table provides a summary of Council’s water supply systems. For Marlborough to achieve its vision for the future the infrastructure must be sufficient and functioning; achievable and sustainable with the resources available Number of Assets per Water Supply Goals Location • The seven water supply schemes will comply with the quality standards of the Drinking Water Standards New Zealand.
