Ngunguru Sports Complex and Golf Course Drain clearing

Online Content Publisher from Whangarei District Council

Council is sending contracting teams this week to begin work improving the tidal drains around the Ngunguru Sports Complex and through a section of the Ngunguru Golf Course.

You might see arborists on site removing vegetation (including some mangrove trees) to clear the channels. This will allow water to flow more easily to sea, meaning the grounds will be drier and less prone to flooding.

Why is this work required?
Self-propagating vegetation such as mangroves establish root and branch systems within the drain passage. As these roots grow bigger they affect the flow dynamics within the drain and allow silt and sediment to settle more readily instead of being discharged to sea as would naturally occur. These deposits built up over time and in effect create more area for root growth. Eventually the capacity of the drain is reduced, posing flooding risks to neighbouring property.

The unwanted material will be removed by arborists in the first stage, then diggers will be sent in to clear out the silt and sludge.

The Ngunguru Sports Complex and Golf Course have been notified separately.
