St. Charles Expansion and Offsite Storm Sewer and Water Main

  • Design
  • Stormwater Management Solutions

This expansion project included the design of accessible site, parking and emergency vehicle circulation elements for this important and central hospital facility in Madras.  In an area with very poor drainage, creative storm water management solutions were incorporated in order to maintain the historical runoff flows while capturing the drainage from the significant increase in hardscape and roof areas.  Solutions included underground chambers for runoff storage, and a weir vault to limit the outfall to the City storm sewer system. 

Along with the on-site development, this project included the design and construction of over 1,200 feet of off-site 18” storm sewer and associated lateral piping, manholes, and catch basins within existing streets.  As part of this project, HWA also completed the design of over 800 feet of 10-inch and 12-inch water main within ‘A’ Street along with associated fire service laterals, hydrants, and pressure reducing valves, completing a tie-in to the DVWD system for the hospital’s fire service.
