This powerpoint presentation begins by providing a brief overview of the City of Tampa and issues the city is facing with the aging and failure of water
distribution infrastructure. Due to the long lifecycle of pipes, the City does
not have reliable data about installation dates and
work orders history; and,
the City did not keep an equilibrium among pipe
infrastructure close to the end of the lifecycle, pipelines
in the middle of their lifecycle, and new pipes. Reactive maintenance results in a large percentage of
pipes in the end of their lifecycle.
Aging hydraulic infrastructure in the City of Tampa results
in
undersized mains with poor hydraulic performance,
deteriorated pipes (corrosion and tuberculation)
that are prone to fail, and
lack the right location of fittings. Valves and accessories are buried
and of
unknown status, and there is a
lack of historic records about maintenance. Lack of efficiency and reduced reliability in distribution systems was the driver behind an effort by the City of Tampa to identify vulnerable portions of the service area where
water distribution system problems are most likely to
occur, and elucidate preventive measurements to
maintain service levels. A Geographic Information System (GIS) was selected as the solution because it allows the water department managers to gather all
the mentioned needs and provide a spatial-framed
solution to satisfy the requirements. The benefits of spatial unit of analysis are provided, along with the methodology. Presentation conclusions indicate the following:
GIS enables planning staff to evaluate and understand
the spatial distribution of negative events within the
distribution area and prioritize capital investment
projects;
water distribution infrastructure aging issues
happen in areas because of the typical development
pattern of the cities; and,
statistics of the negative events within the Section
(unit of spatial analysis) and data mining are good
tools to focus the investment of scarce funds. Includes 4 references, tables, figures.
