MetCom Reports Progress on Water Storage Tower Construction

The Metropolitan Commission (MetCom) provides public water and sewer services to St. Mary’s County operating 17 elevated water storage towers, 37 ground storage towers, and 28 water supply and distribution systems, including 67 wells which annually supply approximately 1.4 billion gallons of water.  In addition, MetCom owns and/or operates 7 wastewater treatment facilities treating a combined daily average of 1.5 billion gallons of wastewater.

The new Charlotte Hall elevated Water Storage Tower (WST) near the Maryland Transit Administration Park and Ride Facility on MD Route 6 serves the Charlotte Hall Town Center area.

The Water Appropriations and Use Permit was obtained from the Water Management Administration and MDE’s Certification of Potability for the well was received on January 15, 2019.  Water quality testing for the storage tank has been completed and the facility has been placed into full operation. This particular tower will provide 400,000 gallons of storage and includes a 250 gallon per minute (gpm) well. 

The new facility will ensure adequate fire suppression (as the only available water for fire protection is owned by the Charlotte Hall Veterans Home), address storage lost due to a damaged ground storage tank and provide water storage for domestic use. The approved capital construction budget was $3.107M and was funded through a low-interest loan from the Department of Housing and Community Development.  The project was made successful through the efforts of MetCom staff, the contractor (Caldwell Tanks, Inc.) and Designer (WR&A).

George Erichsen, MetCom’s Executive Director stated, “We are pleased to have the Charlotte Hall water tower on line, and we are now pressing forward on the construction of what will be the largest MetCom water tower” (see rendering at right).

A much larger, two million gallon composite water storage tank in the Hickory Hills community (located behind the new Nissan dealership on MD 235) will replace the existing 500,000-gallon facility, built-in 1992.  The new facility has an approved budget of $6.297M for the storage tank and $0.997M for the new 700 gpm well which replaces the 1982 well and draws water from the Patapsco, not Aquia Aquifer. A new well house, pump controls, disinfection/metering/telemetry equipment, a stand by diesel generator and demolition of the existing tower are included in the contract.

Bids were opened on July 10, 2019, and the MetCom Board approved the recommendation for award on August 8, 2019. Construction is anticipated to be completed 710 calendar days following the formal Notice To Proceed. 

This project will help stabilize water system pressures throughout Lexington Park as well as improve water storage deficiencies to meet the current water demands of the community. This project is funded through a low-interest loan from the Department of Housing and Community Development.  The project has come to fruition due to the efforts of MetCom staff and project designer, WR&A.

The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.

To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at

Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
