Hornsby Shire Council – Design and Construct CDS P1518 Unit with DD Sump 2/4 GPT Projects

Optimal Stormwater was selected by Hornsby Shire Council to design and construct a new stormwater treatment solution upstream of an ecologically sensitive creek within Neal Reserve, Sherbrook Road, Hornsby. The existing basket-type GPT was well undersized and causing upstream flooding issues. Optimal Stormwater designed and constructed a CDS P1518 solution with double depth sump to treat the 32ha catchment.
