Mangawhai Storage Dam

During 2009, Wharehine Construction was contracted to build a 40,000 square metre (10 acres), 6 metre deep lake known as the Mangawhai Storage Dam on Browns Road, Mangawhai. The project included 72,000 m³ of cut to fill, 2.3km of underfill drainage, 190,000m³ of storage volume, 8000m³  PAP 7 for the pond lining plus 13 km of irrigation pipe work. The bulk of the works took from February through July.

The storage dam is the termination point of the Mangawhai Wastewater scheme which has been under development in the area for the past 18+ months. The wastewater treatment plant at Thelma Road (of which Wharehine Construction was also involved in last season) along with the storage dam are major components in helping to protect the environment and enhance the beautiful harbours and waterways Mangawhai has to offer.
