Denver Water Work in Downtown Littleton

Denver Water is replacing the water main on Rapp Street, between Alamo and Church Avenues. The replacement work kicks off a major project to replace aging and leaking pipes in and around Downtown Littleton and will eventually include 1,500 feet of new pipe on Main Street from Sycamore to Rapp Streets possibly starting in 2022. The investment in this project now will reduce the need to make emergency road closures for leaks and repairs later.

The Rapp Street repairs started at the end of September and should take 4 to 6 weeks. The project will create inconveniences as several businesses will experience water outages. Any planned outages will be communicated in advance. There will be full road closures since the new water main will be laid directly down the middle of Rapp Street. Access will be allowed for people getting to their homes and businesses. Parking will be prohibited on Rapp Street between 7 a.m. and 5 p.m. as equipment and materials will be staged along the street.

The project will replace water mains dating to about 1950. Additionally, Denver Water will replace any customer-owned lead service lines connecting the water main to any homes or businesses — at no cost to the customer. Denver Water has met with the Littleton City Council and Littleton Downtown Merchants Association to talk about the work and letters were mailed to property owners on August 30. Door hangers will also be posted to communicate about the project. For questions contact Denver Water Customer Care at 303-893-2444 (7:30 a.m. – 5:30 p.m., Monday – Friday) or visit
