Serving Northern Virgina / Washington DC Metro Area Customers Since 1987
At SES, we design, construct, operate and manage individual, commercial, and community water and wastewater systems. We are especially proud of our people and their dedication to making a difference in our community. As a matter of fact, at SES, our people are our difference. We hope to inspire positive change by enriching the lives of others with the products and services we provide.
Founded in 1987, SES has served thousands of clients with soil interpretations, environmental investigations, septic-drainfield designs, decentralized wastewater systems, and stormwater management services. In June, 2013 we relocated to a state-of-the-art facility in Manassas, Virginia, allowing us to harness the latest technologies while staying rooted in our primary practice of soils and environmental science. Our core competency is strong as our professionals and principals are leaders in their respective disciplines who assist in writing legislation that supports environmentally responsible development. We stay on the cutting edge to provide comprehensive onsite water and wastewater system services to you.
After 26 years in business, we are honored our clients, including homeowners, realtors, builders, developers, business owners, property managers, architects, planners, and government agencies, trust us to design onsite and alternative sewage systems and maintain their stormwater facilities and depend on us to remove leaking oil tanks, ensure safe drinking water, repair septic fields, and remove grease from restaurants. They know SES provides peace of mind while protecting their investments and the environment.
With years of design/build experience, SES is an ideal sub-contractor for large projects, and is able to turn-key smaller projects, such as individual onsite septic systems (or OSS), septic system repairs, and stormwater infrastructure repair and upgrades.
