A major hurdle that was overcome was the lack of as-built information
of the system. A twofold solution was immediately implemented
by compiling electronic drawings and models- addressing the immediate
needs of the project, and to establish record drawings for the
Client for future use - updated schematic drawings of the system
is still being compiled and updated on an ongoing basis.
The crux of the programme lies in monitoring the entire supply
area in sub-divided management zones or districts. Each district
has been equipped with a dedicated district water meter to ascertain
the night flow by data logging. The results obtained from data
loggers are evaluated and interpreted regularly, the direct results
of remedial measures are noticeable within reasonable time.
