DBS&A supports landfill operators and hazardous waste managers by providing regulatory, scientific, and engineering solutions at hazardous and municipal solid waste landfills, land disposal units, waste isolation facilities, and mine sites.
Our experience includes siting, permitting, design, construction oversight, and monitoring for facility expansions, permit modifications, and closures. We have shepherded high-profile sites through all phases of Environmental Protection Agency approval. We maintain a superior record of providing value when considering clients’ expectations of cost, quality, and schedule. Our public and private sector clients include municipalities, counties, private operators, the Department of Energy, and the Department of Defense.
DBS&A is an international leader in the design of evapotranspiration covers (ET covers) for arid regions, also referred to as store-and-release cover systems. Based on site-specific conditions, ET covers can provide improved cover performance, erosion control, and reduce long-term maintenance concerns. DBS&A has gained regulatory approval of this design by demonstrating its success in the U.S. and recently put this experience to work internationally.
DBS&A also has experience in design of waste-to-energy, cogeneration facilities using landfill produced methane gas to power water treatment facilities.
