Washington Street Cast Iron Water Main Replacement Project

Last Updated: August 17, 2026

Project Status: 🟢 Mobilization – Construction Activities Beginning

The North Washington Street Water & Sanitation District is moving into the mobilization stage of the Washington Street Cast Iron Water Main Replacement Project. This important infrastructure improvement will replace aging cast iron water mains and improve the long-term reliability of the District's water distribution system.

Project Information

• Contractor: Colorado Civil Infrastructure
• Location: Washington Street from 59th Avenue to 66th Avenue
• Final Completion: February 16, 2027

Current Project Phase

As of Monday, August 17, 2026, the project has officially moved into the mobilization stage.

Saw cutting and potholing crews are scheduled to begin work today, August 17, 2026. These activities will allow crews to verify existing underground utilities and prepare the project area for water main construction.

Traffic control devices and construction signage will also begin going up throughout the project area as crews establish work zones and prepare for upcoming construction activities.

Construction Sequence

Construction will begin near the intersection of 66th Avenue and Washington Street and progress south toward 59th Avenue. Work will be completed in phases to help minimize impacts to residents, businesses, and traffic.

Initial activities will include saw cutting, potholing, traffic control setup, and other site preparation work ahead of water main installation.

Traffic & Water Service Impacts

Motorists should expect to begin seeing traffic control, construction signage, equipment, and crews along Washington Street as mobilization progresses.

Temporary lane closures and traffic pattern changes may be necessary within active work zones. Drivers are encouraged to use caution, reduce speeds, and follow all posted traffic control signs and directions from construction personnel.

As water main construction progresses, temporary water service interruptions may be necessary. Affected customers will be notified in advance whenever possible.

 

South Side Phase 3 Water Line Project

Last Updated: August 17, 2026
Project Status: 🟢 Under Construction

The North Washington Street Water & Sanitation District is completing the South Side Phase 3 Water Main Replacement Project using District Operations staff.

By self-performing this project, the District is able to reduce construction costs, maximize the value of customer rate dollars, maintain high construction standards, and complete critical infrastructure improvements using its experienced in-house workforce.

South Side Phase 3 is replacing aging cast iron water mains with new ductile iron water mains throughout the South Industrial area. These improvements will strengthen the District's water distribution system, improve reliability, and help provide dependable water service for decades to come.

Benefits of the Project

• Replaces aging cast iron water mains with modern ductile iron pipe.
• Improves the reliability and performance of the water distribution system.
• Reduces the potential for future water main breaks and emergency repairs.
• Lowers long-term maintenance and replacement costs.
• Enhances fire protection and overall water system resiliency.
• Maximizes the value of customer rate dollars through self-performed construction.

Project Locations

✅ Completed

• E. 58th Avenue & Logan Street
• E. 57th Avenue
• Pivot Alley

🚧 Current & Upcoming Work

• Logan Street
• Logan Court to Logan Street Water Main Loop — District crews will begin construction today, August 17, 2026.

The District will be installing a looped water main from Logan Court to Logan Street using 8-inch ductile iron pipe. This new connection will create a loop within the District's water distribution system, improving water circulation, system reliability, and overall resiliency in the South Industrial area.

The District will continue to provide project updates as construction progresses.
