Whanganui letters: Water solution a 'no brainer'? 7 Jan, 2021 04:00 PM 3 minutes to read Whanganui Chronicle Water solution a 'no brainer'? In regards to subdivisions and water, would it be prudent and cost saving to suggest to new homeowners to install a rainwater tank at each house. Whanganui and Rangitīkei seem to be building subdivisions and housing at speed, with Marton currently working on the Hereford Heights subdivision of roughly 80 new houses. Given the climate change problem, and the current state of the district's water and reservoirs, this seems a better option than sending the rainwater down the drain to the sea. The current state of the water in Marton does not seem to be coping with the existing houses, as the water level and quality decreases. It may also be important to note that with the increase in housing, the stress upon the state of the water could cause further issues.
