Infrastructure Strategy - Renewal of around $35M of the water reticulation network over the next thirty recently updated Marlborough Environment Plan and the conditions of resource years consents that support the plan. Rivers and land drainage: Improving the quality and the quantities of water used and discharged back into the the need to respond to higher expectations related to flood protection and natural environment will require ongoing investment in our wastewater and stormwater - environmental outcomes assets. Actions will include progressive implementation of the Blenheim Stormwater Strategy and its extension to other urban areas in the region. - the impacts of coastal storm waves and sea level rise on the effectiveness of the existing land drainage system The upgrade of wastewater treatment plants to meet increasing volumes of wastewater potential impacts of climate change on flood flows particularly from the wine industry and increasingly stringent standards for effluent - discharge. Also meet the cultural requirements to avoid or restrict the volume of waste returned to the aquatic environment Stormwater: the effects of urban growth and climate change on stormwater volumes To deploy water demand management tools to promote more efficient water supply, - reduce leakage and ensure water resources are sustained for future generations. - the need to improve the quality of stormwater discharges - ageing infrastructure. Around $16M of stormwater reticulation is expected to have Renewals reached the end of its useful life within the next 30 years For all types of assets, the preferred option is to implement a proactive, planned Community Facilities: renewals programme and invest in more condition assessment technology, field data collection and data management. This will enable informed decision making on the provide facilities that meet the changing needs of the local community and are most cost effective timing of renewals. Enhanced condition assessments will be - attractive to visitors to the region particularly valuable for our underground assets. - to anticipate and respond to changing technology and its impact on traditional Resilience to climate change and natural hazards facility use Ongoing investment in our resilience plan will ensure roads are reopened as soon as possible after a major natural event or other disruption. Preferred options for responding to these challenges The Council will soon begin a review the core Wairau River Floodway Management The Council’s preferred options for address the challenges are summarised below. Plan. The review will examine the current level of service, customers’ expectations and land use changes. It will also model flood flows under different conditions so that the Legislation range of effects that may result from climate change and sea-level rise can be more accurately predicted. Minor upgrades will be sufficient to preserve existing levels Changes in legislation particularly affect our water-related assets. We intend to of service to about 2050 but after that time other options, including accepting complete existing water treatment plant upgrades for Seddon, Renwick and Havelock increased flood risk or a managed retreat from some low lying areas, may need to be and install treatment to Wairau Valley and Riverlands and point-of-entry treatment considered. devices for each household in Awatere Rural to meet the Drinking Water Standards. Building infrastructure to the latest standards and with the most suitable materials National guidance on environmental standards will continue to be provided through the increases resilience to flood events and earthquakes. We are also prioritising the National Policy Statements. In particular the National Policy Statement for Freshwater replacement of pipework and other assets made of older materials that are susceptible Management, National Coastal Policy Statement and the National Policy Statement on to natural hazards or have deteriorated more quickly than anticipated. Urban Development Capacity. Local implementation of the policies will be through the 2018-2028 Long Term Plan Page 169
