Stormwater Maintenance
Whenever heavy rain is forecast our team and our contractors are out and about in Waihī Beach checking that there’s nothing blocking the drains or preventing the stormwater from draining away.
Our 'pre-rain check' is triggered by heavy rain warnings received from NIWA. Councils contractors check problem areas for issues to make sure they are clear.

We've noticed an increase in service requests concerning vegetation growth in our open drains, and we appreciate the community's vigilance in reporting these concerns. We want to take this opportunity to clarify our approach to addressing vegetation in these areas.
When we clear drains, our primary focus is on maintaining clear pathways at the bottom of the drain or the main channel; is depicted in the image below. However, we also aim to retain vegetation along the banks and slopes wherever possible. This strategic approach serves multiple purposes that benefit both the environment and the community.
Firstly, retaining vegetation on the banks and slopes helps stabilize the drain walls, reducing the risk of erosion. This is crucial for maintaining the integrity of the drainage system and preventing potential damage to nearby properties.
Additionally, vegetation along the drain can play a role in treating stormwater. Plants have a natural ability to filter pollutants and absorb excess nutrients, improving water quality before it reaches our waterways. Standing water in a drain is not always a sign of a blocked system. Standing water can enhance water quality by allowing pollutants to settle and be filtered by plants and soil, reducing runoff speed and promoting groundwater recharge. This natural filtration system captures contaminants, supports vegetation, and helps regulate runoff temperature, protecting local water resources and ecosystems.
By preserving vegetation where feasible, we're not only addressing immediate drainage concerns but also contributing to the long-term health and resilience of our local ecosystems.
We thank you for your understanding as we work together to ensure the effectiveness and sustainability of our drainage infrastructure. Tell us if you spot a problem with your stormwater drainage system so we can do something about it. Either email, phone, or message us through Antenno.
