Wastewater upgrade for Coromandel 24 February 2015 Stage three of a floating wetland and upgraded inlet works at the Coromandel Wastewater Treatment Plant is to get underway shortly. A resource consent for the wastewater treatment plant, which has been located on Hauraki Road, Coromandel, for the last 30 years, has recently been renewed. Part of the consent condition is upgrading the Plant to comply with the current standards. "Preparation of the site started earlier this month and we estimate the upgrade being completed by late May. Veolia Water is still operating the wastewater treatment plant during the upgrade," says Ian Smith, Water Services Manager. Stage three includes installation of embankments, pond liners, baffles, a new pump station and a septage waste tank which will improve the capacity of the ponds and will add a further 25 years to the life of the wastewater treatment plant. During the works, there will be large vehicles used for moving clay spoil for the embankments. This should have minimal effects on residents of Hauraki Road, who we have briefed about the works. Site preparation started earlier this month.
