The board was among 29 submitters on the draft stormwater management plans for the Halswell and Heathcote rivers. Adjacent to the Owaka Pit on Wilmers Rd, a former stormwater retention basin was one of the three sites the board recommended for early investigation in the board’s Halswell River submission. Catering to the nearby industrial area, the stormwater retention basin by the intersection of Halswell Junction Rd and Springs Rd was also listed. This would mean would less contamination, particularly of copper and zinc, which stormwater picked up from roads.
