A rainwater harvesting system at a new toilet block at Phyllis Reserve is delivering a double benefit, Auckland Council reports. Excess rainwater at the site will be collected in a large tank behind the toilets, preserved and used, rather than it going from the roof into stormwater drains. This helps prevent soil erosion, flooding and pollution from stormwater run-off into waterways. The initiative has been welcomed by locals who volunteer at the park, residents and Albert-Eden Local Board members.
