All Service Contracts Include Required Inspection and Maintenance


Loudoun County is in it's second year of required inspections for alternative septic systems. Local ordinances were adopted before the State mandated inspections. Loudoun's local ordinance allows the County issue fines for those who do not comply. No fines were levied during the first year but could be levied on those who don't comply in 2010. Inspection and maintenance is good for your septic system and many of you in Northern Virginia recognized the benefit of routine maintenance and have had SES maintain your systems for many years. Thanks and please recommend us to your friends with alternative or conventional septic systems.


Fairfax County notified owners of alternative septic systems that annual inspections are now required by State Law. Local ordinance requires owners of conventional septic systems to have their septic tank pumped or cleaned at least every five years. SES recommends that all septic systems, conventional and alternative be inspected annually and tanks cleaned or pumped out as needed based on the inspection. SES has several licensed operators and can help you notify the Health Department that your system is being operated by a licensed professional as required by Law.


All county health departments will or have already notified owners of alternative septic systems of the new requirements for annual inspection and maintenance by a licensed operator. Inspection and sampling requirements are a little different for new and existing systems but it should be clear that no alternative system is exempt from the annual inspection requirement.

Regulations effective April 10, 2010 require alternative septic systems to be inspected annually and maintained in accordance with manufacturer's recommendations or local ordinance whichever is stricter. In addition, Counties within the Chesapeake Bay Area require conventional septic systems to be pumped or inspected every five years. Pending civil penalty regulations and some local ordinances allow the Health Department to fine those who fail to comply. Regular maintenance of conventional and alternative septic tank systems along with the proper use of your septic tank system will not only help assure that your system is functioning correctly but also helps assure our streams, rivers and ultimately the Chesapeake Bay watershed is protected.
