Background

The Greenbelt Standpipe is a two-million-gallon steel elevated water storage facility located at 211 Ridge Road in Greenbelt, Maryland. The elevated tank and associated onsite inlet/outlet piping were constructed in 1936 and nearing the end of their service life.

WSSC Water purchased the adjacent property at 241 Lastner Lane, which includes an existing dwelling. As part of the project scope, this dwelling will be demolished. Incorporating the additional area into the site will help reduce construction costs, provide a safer working environment for crews and enhance WSSC Water’s ability to maintain the facility in the future.

Project Scope

Site Work

The project calls for replacing existing facility yard piping and valve vaults, which will connect to the existing water main located at Ridge Road and Lastner Lane. Site work will also include a new perimeter security fence/gate and repaving of the site driveway. The site will have new landscaping, which includes trees, bushes and a pollinator garden.

Structural

Due to the age of the facility, upgrades to the structural steel and concrete foundation are included as part of the project, which will extend the service life of the tank. This portion of the project also includes updating ladders, balconies and tank access to meet current Occupational Safety and Health Administration (OSHA) standards, to ensure WSSC Water personnel can maintain and work around and on/in the tank safely. 

Tank Coating

The tank's interior and exterior will be recoated with a new epoxy-based coating that will protect the tank from corrosion and have a service life of 25 years. The process includes removing the existing coating by abrasive blasting, then cleaning and preparing the surface before the new coating is applied.

For the tank's exterior, the City of Greenbelt ran a survey through January 5, 2026, of four paint schemes currently under consideration. Residents were invited to visit the survey page, review the four options and submit their choice before the deadline. 

Containment System

A Class 2-A containment system will be erected around the existing tank structure to provide two important functions:

  • To contain particles from the removal of the existing coating within the system. The contractor will abide by OSHA, Environmental Protection Agency (EPA) and all other applicable codes for disposing of the waste produced from the coating removal process.
  • To prevent overspray during the painting process.

Water Quality

Throughout rehabilitation, the tank will be drained and out of service, isolated from the water system. After the construction completion, the tank will be cleaned and disinfected by WSSC Water. We will also collect water samples for testing; results must be approved by the Maryland Department of the Environment (MDE) before returning the tank to service.

Community Impact

The majority of the community will have no water service impact during the rehabilitation process.

However, during the project, there will be an approximately four-hour water service shutdown related to the service tie-in that will affect approximately 11 homes on Lastner Lane. Affected residents will receive advance notification with more information prior to the scheduled shutdown.

Residents in the area should expect minor traffic impacts due to the delivery of materials and equipment to the project site. To help minimize disruptions, no deliveries to the site will occur between 8:15 a.m.–10 a.m. and 2:30 p.m.–4 p.m. to avoid school bus pick-up or drop-off. 

Construction Schedule and Timing

The contractor is expected to mobilize to the project site in early November to install sediment control and soil erosion measures.

The timeline for this project began with the Notice to Proceed on August 18, 2025. Project tasks in fall 2025 will include mobilization, demolition of 241 Lastner Lane, pipe and electrical work and altitude valve vault. In winter 2025/spring 2026, the work will focus on steel upgrades on the standpipe and erecting the containment system. In spring/summer 2026, the tank will be coated. Site work in fall 2026/winter 2027 will include landscaping, fencing, paving and grading. Substantial completion is set for February 9, 2027.
