The Loudoun County Health Department 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 between January and July 1st. 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. Call SES to schedule these services immediately.



If you recently got a letter from the Virginia Department of Health about your Alternative Septic System, SES is highly qualified, licensed, and able to complete your required inspection and file the required reports.

But this year, we aim to take it to the next level by not just giving once, but giving to a different charity each month of 2020!
