Comments on: Tukituki wastewater update http://www.baybuzz.co.nz/archives/1785/ What's new, funny, perplexing in Hawke's Bay Wed, 08 Feb 2012 20:59:18 +0000 hourly 1 http://wordpress.org/?v=3.1.3 By: Morry Black http://www.baybuzz.co.nz/archives/1785/comment-page-1/#comment-19811 Morry Black Wed, 16 Dec 2009 19:28:43 +0000 http://www.baybuzz.co.nz/archives/1785#comment-19811 A few years back when CHBDC applied for the consents to continue to operate their oxidation ponds, there was a proposal put forward by another party to apply the wastewater from the Otane ponds onto land for the irrigation of eucalypts. Some of the questions HBRC and CHBDC asked the proponents of the scheme were in relation to: a) How much of the wastewater would the trees take up? b) Have you done leaf analyses of the plants to provide information on this? b) What will happen to the pathogens and viruses? c) Is there a clay layer under the land to prevent leaching of wasterwater to ground water that is being used for domestic or farm supply? d) What about runoff from the land and where will it go? The stormwater infiltration thing was also left in the too hard basket. It will be interesting to see if HBRC applies the same amount of rigour to their own proposal.
