  

This project involved installing 850m of wastewater rising main and a pump station. This included a 440m drill shot under the Mangawhai estuary. The drill shot was located at low tide using a Digitrack® F5 walkover locator to depths in excess of 6m. The DitchWitch® JT8020 drill was used for this drill shot accompanied by the Triflo mud recycling and mixing system.
