Attention: Alternative & Conventional Septic System Owners
The VA Department of Health is ramping up enforcement of annual Alternative Septic System inspections and required routine pumping of conventional septic systems.

Alternative systems must be inspected every year*. Septic tanks must be pumped out every five years. Failure to do so leaves property owners at risk for monetary penalties and possible misdemeanor criminal charges. *Loudoun County requires inspections between January - July

Communal Septic Systems

When multiple residential dwellings or mixed uses are connected to a single onsite sewage system, they are commonly referred to as communal, community, or mass onsite systems. All designs for communal systems require a Professional Engineer to direct the process from the preliminary engineering conference to the final plans and specifications.

SES is well equipped to design and construct your next communal system and has experience with systems from 6 to 156 homes.

Absolutely fantastic experience with SES Mid Atlantic and Mike Cox. I contacted them to help locate my septic distribution box and field. They went well above and beyond what i expected. They had to dig several deep holes since the distribution box was about 500' from the tank, and about 10' deep. Mike and his team were determined to find it, and did not give up until they had. Others had tried, but only SES succeeded. Darwin and Jose also did an excellent job filling the holes and replacing the sod. They will be my septic service from now on, and I highly recommend them to anyone

Had a bad situation, tank backing up in the yard cause our pumps were not transferring to the field. SES had someone out here within a day and the pump truck coordinated to get here prior so the tank was emptied. Able to diagnose the problem and got the parts in a few days (control board estimated at 5-10 days). As soon as they had it in hand they scheduled to come back out and got it fixed. Great group with the right mix of personal touch and technology to make it easy.

Mike and the SES team were great from the start when i had to move my septic line. Mike walked me through the process, handled all of the coordination, and completed the work quickly. The SES price was also very reasonable.

Mike and his team are awesome! We just had our septic distribution box, splitter boxes and header replaced on a monster drainage field. Very professional and thorough! SES Mid Atlantic is definitely the way to go.

SES was super responsive and fast to act during a very busy time. As a real estate professional, it’s comforting to work with a company who values the customer’s experience as much as I do. Their communication was excellent and they are true professionals.
