Local iwi, the wider Raglan community and other stakeholders have expressed a strong preference for a discharge to land option, which we have been investigating for several years.
Since 2019, with help from Watercare which is contracted to deliver the Councils waters services, we have widened our investigations to include other alternatives. For example, we’re currently assessing the potential for schemes that combine the reuse of reclaimed water for summer irrigation with an alternative discharge during winter. More advanced treatment plant types have also been assessed that could replace existing oxidation ponds.
Given the complex technical engineering, environmental and cultural considerations involved in the option assessment process, these investigations have taken considerable time. As part of these investigations, we must assess the costs and affordability alongside cultural and environmental considerations.
