By 1990, the Department of Water and Sanitation had produced about 150 technical reports
in the "TR" series. Some paper copies still exist: contact
The Librarian, Resource Quality Services to check availability.
Where reports are avaliable in PDF format, the links are shown in dark blue
(note that some scanned files may be quite large). Certain
Technical Notes and other archival material are also available.
