Onsite Stormwater Detention    
  • On-site Stormwater Detention (OSD) Handbook, 4th Edition
    The Trustís OSD policy was developed in conjunction with the four councils and was adopted by each of the councils in November 1991. This Handbook spells out the OSD policy and provides guidance for OSD designers, property owners and others involved with development. Although primarily concerned with the Upper Parramatta River Catchment, the Handbook also shows how the procedure on which the policy is based can be adapted to provide approximate parameters in other locations.

  • Stormwater Facilities Database.
    This database contains all the necessary information about both water quality and water quantity assets in the catchment and across the four council areas (Baulkham Hills, Blacktown, Holroyd and Parramatta). While primarily a management tool, much of the data is publicly available through the above link.
