What DN Tanks does
DN Tanks (legal entity DN LLC) is a US-based, privately held specialty construction contractor that designs and builds prestressed concrete storage tanks for liquid containment. Founded in 1929 and operating with 251–500 employees, the company serves municipal water utilities, wastewater treatment facilities, and — increasingly — thermal energy storage applications for power and industrial customers. Its core products are prestressed concrete tanks for water storage, wastewater storage, and thermal energy storage, supported by a Concrete Tank Services line covering rehabilitation, retrofitting, and inspection, and by Preconstruction Services for early-stage engineering and design support.
The underlying technology is specialized prestressed concrete tank construction, marketed around multi-generational durability and lowest-maintenance performance. Project examples include two 18.45 MG wastewater tanks at the Back River Wastewater Treatment Plant in Baltimore, four 16.0 MG tanks at the Eastside Water Treatment Plant in Dallas, and a 3.0 MG reservoir repair at Charter Oak in Covina, California. The company maintains a national footprint with documented completed projects across Montana, California, Maryland, Michigan, Texas, and Massachusetts.
DN Tanks generates revenue through custom, project-based contracts with municipalities and government agencies, priced per project on capacity, site conditions, and specifications rather than via published rate cards. The go-to-market motion is consultative enterprise field sales supported by inside sales, a representative finder, and a bilingual (English/Spanish) corporate website. Multi-year project lifecycles from preconstruction through completion drive revenue recognition, and the installed base provides a recurring pull-through opportunity via the Concrete Tank Services aftermarket line. The company is led by President Charlie Crowley and operates as a privately held LLC with no disclosed parent, subsidiaries, institutional investors, or funding rounds.
