Construction planning and use of technology for greater environmental outcomes
Really pleasing to see a growing focus and commitment to achieving great environmental outcomes through good construction planning and use of new technology. The photo presents just one example of the increasing number of sites which Topo has inspected over the recent period which are making genuine efforts to improve the level of ESC compliance. The high efficiency sediment basin (Type B) constructed by Shadforth at their Oxley site highlights this commitment to improvement, no longer do we see a 20 cubic metre hole in the ground expected to treat a 10 ha catchment, but rather a well constructed sediment basin, incorporating the principles and key design elements as per the revised Appendix B (IECA, 2018) document. This basin has adopted a flow based automated dosing unit supplied by Flocca, which can accurately dose the nominated ACH coagulant and achieve rapid settlement of runoff prior to discharging offsite.
