Visit our YouTube Channel

Since 1987, SES has performed environmental investigations, soil interpretations, stormwater management services, septic-drainfield designs, water and wastewater systems operations and maintenance for thousands of loyal clients in Maryland, Virginia and Delaware.

With years of design/build experience, SES is a natural sub-contractor for larger projects, while still providing reliable turn-key services for individual onsite septic systems, also referred to as OSS, septic system repairs, and stormwater infrastructure repair and upgrades. While our commitment to our clients sets us apart, 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.

As a licensed, privately-held public utility, our work as water and wastewater system operators benefits our clients not only in significant cost savings, but in the peace of mind they get knowing SES has single-source responsibility for their system from inception to ongoing operation. Our professionally licensed staff of soil scientists, system evaluators, designers, installers, and operators has extensive experience and receives ongoing training in the latest industry developments. We work together to deliver water and wastewater system solutions that are right for your project.

When you choose SES for your design/build project you join the ranks of satisfied clients, such as Toll Brothers, NV Homes, Van Metre Homes, Loudoun County Parks, Northern Virginia Regional Parks, and 7-11.

SES design/build services include:

  • Soil investigation,
  • OSS design, construction permitting, and installation,
  • Well water and water system design and construction,
  • Single lots for individual homeowners,
  • Subdivisions with individual OSS and wells, and
  • Subdivisions and commercial properties with community OSS and water systems

Whether you own your property, manage public facilities, or are developing multiple lots for subdivision or commercial use, trust the dependable professionals at SES to perform top-notch OSS maintenance and inspection, and well water and water system operation and maintenance.
