The City and County of Denver Infrastructure Project Management is working to improve and repair sanitary mainlines in the city's residential neighborhoods. The sanitary mainline is a large pipe where the water from residential appliances (dishwashers, washing machines, sinks, toilets, showers and bathtubs) flows after it leaves a home or business. The sanitary mainline is usually located in the street or alley adjacent to the property. Some of these systems are more than 100 years old. 

The process uses a polymer resin lining to preserve the integrity of sanitary systems, preventing failures in older lines and minimizing any leakage into soil or waterways. This method is also less invasive to neighborhoods compared to open cut projects around the City. Each main can be lined in a single day, allowing crews to complete work on a street with minimal traffic or access impacts.

Denver is installing a new storm sewer system in the Curtis Park neighborhood to provide 5-year storm protection to residents and businesses in the area and important drainage improvement around RTD’s East Rail Line. Five Points, Whittier, and City Park West neighborhoods are also situated in these drainage basins.

Storm drain construction starts at the South Platte River progressing uphill in 33rd Street, crossing the Downing Street intersection and continuing upstream in Martin Luther King Boulevard from Downing Street to Lafayette Street.

Construction is scheduled in several phases. The first several phases have been completed. Phase 4 is expected to begin in late 2018.

Updates and details about the 33rd Street Outfall project

The City and County of Denver is making improvements to the existing 38th & Holly Detention Pond. During small and larger storm events, water collects in Holly Street at depths up to approximately 1.5 feet. The water then overtops the pond embankment along Holly Street to enter the pond and causes severe erosion to the embankment, creating on-going maintenance concerns and repairs.

The project will construct a new rundown to prevent future erosion, provide stormwater quality, and significantly re-landscape the detention pond and plant trees for pedestrian shade. When the improvements are complete, the project will safely direct stormwater into the detention pond while improving the water quality and the aesthetics for the surrounding neighborhood.

Construction is beginning in Fall 2018.
