Large Valve Replacement Project - 9th St, Hamilton Ave and Illinois Ave

Overview

DC Water is replacing large diameter valves at various locations throughout the city as part of its Capital Improvement Program to improve the water system infrastructure.  These efforts will improve water quality and system reliability, increase water pressure in some areas, and maintain adequate flows throughout the system. The project location is at the intersection of 9th Street NW, Hamilton Street, NW and Illinois Avenue, NW.

Scope of work

  • Installation of a new 48-inch valve
  •  Replacement of approximately 80 linear feet of a 48-inch water main

Schedule

  • Construction start: May 2016
  • Construction completion: January 2018
  • Normal work hours: 7:00 a.m. – 7:00 p.m., Monday through Friday
  • Contractor may work at night or on weekends, dependent upon needed tie-in work or inclement weather

Important information

  • If a planned temporary water service shut-off is necessary, affected residents will be notified 48 hours in advance.
  • Unless otherwise requested or required, contractor shall not work between the rush hours of 7:00 a.m. – 9:30 a.m. and 3:30 p.m. – 6:30 p.m., Monday through Friday, along major thoroughfares and collector streets.
  • Construction may cause temporary discolored water or low water pressure. If you experience discolored water, flush cold water taps for 15 minutes. If water does not clear, contact the DC Water Drinking Water Division or 24-hr Emergency/Command Center.

Traffic plans

  • Lane closures may be required daily with approved traffic plans by the District Department of Transportation (DDOT).
  • At various times during construction, “no-parking” signs may need to be placed in certain areas in and around the job site.  Notifications regarding “no-parking” zones will be posted 72 hours prior to construction, as required by DDOT.

Partners
