Several years ago, the Horowhenua District Council built pond areas to improve stormwater flow during rainfall events around the basin area of Foxton beach.

This helped, but when the tide came into the estuary, the stormwater had nowhere to go! The council had previously installed a Penstock gate valve which was unsuccessful as it didn’t work when required. The council had intended to replace this existing Penstock valve with a new Solar Actuated Penstock. But once hearing about how the Wastop Check Valves worked, they decided to purchase two DN750 Wastops for installation on an old DN750 Concrete pipe. They were originally going to be installed at the upstream end of the pipeline, but then at the last minute, the decision was made to place them at the outlet. This was a much better decision, being the safer option to check for blockages etc.
