The process includes converting storm drain related drawings into San Diego’s geographic information system (GIS) to alleviate a backlog of work and provide city officials with a more comprehensive picture of their storm water system.
The project, which began in early 2008, was initially expected to take 14 years to complete due to the backlog of almost 3,000 hard copy drawings waiting to be converted into the city’s storm drain GIS. Thanks to similar GIS projects which have been completed by MWH, it is expected that the conversion works will now be completed by the end of 2009.
MWH also conducted an asset management review to identify other engineering and construction information from the final drawings that should be entered into either the GIS or the city’s asset management database to better monitor and administer ongoing storm drain projects.
San Diego-based MWH Project Manager and MWH Business Solutions Group Vice President Peggy Umphres said “We were pleased to help San Diego officials with a storm drain GIS and asset management project that supported their focus on consistency and efficiency, while using our wet infrastructure expertise.

San Diego’s GIS now includes important information such as storm drain materials, diameters and connections to help city officials effectively plan for servicing needs, future projects or tracking of storm water.
