(April 15) -- MAP of planned construction for the sixth street watermainKirkland's Sixth Street water main contractor is an estimated two non-consecutive days from completing the installation of a quarter-mile-long section of water main, from Central Way to Kirkland Avenue. 
Kar-Vel Construction's crews will be working in Second Avenue to connect the new 12-inch water main in Sixth Street to the existing eight-inch main that runs beneath Second Avenue. To achieve this, crews will shut down water service to select properties along Second Avenue. Those affected will receive two-days notice.

Why: Customer-demand for water will soon exceed the 8-inch concrete pipe’s capacity.

What to expect: Traffic control and flagging operations will be in effect. Short delays are possible during construction.

  • The City of Kirkland requires the contractor to backfill and/or cover trenches and other unfinished work at the end of each day.    
  • Access for mail delivery, garbage pick-up and emergency vehicles will be maintained.
  • The City of Kirkland will notify residents of any disruptions to water services prior to the disruption.

Contact: Aparna Khanal, project engineer, (425) 587-3827,; or Christian Knight, Neighborhood Services Coordinator, and (425) 587-3831.
