"Almost universally speaking, septic problems on weekends are never a good thing. Our basement started flooding and we discovered it as a septic issue. I started calling around — most businesses could not help until several days later. I finally called Josh at Great Falls Septic’s emergency line. He came quickly and had a swift plan of attack upon arrival. He give me the rundown of the problem, and gave us advice on how to avoid issues in the future. Josh was reliable, smart, skilled and honest. And well priced. I can not say enough good things about josh and Great Falls Septic. They made and awful Saturday morning flood turn into a great business experience. Thank you!"

Customers say: Quick response

"Loudoun Septic was very straightforward, no-nonsense, and predictable which is very appreciable. They were very responsive and very communicative and did exactly what they said they would do when they said they would do it. They offered a few options but didn't put the hard sell on anything. I would use these guys again in a heartbeat."

"They were remarkable. First, they excavated the minimum needed to repair our drain and install the CIPP liner. They saved our front cement and brick staircase (directly over the main house sewer line). They only removed one section of the sidewalk that was over the main house sewer line. When done, they filled and compacted the dirt, covered the lawn with straw (i.e., ready for me to add seed and to avoid erosion) and replaced the damaged sidewalk section. The workers were polite and respectful of both us and our property. There was truly minimal disruption to the household. We could not flush toilets or run water down the drains for about 3 hours each day they worked on the line. We contracted for repair of the pipe that was on our property. They completed this work in two days. We then added re-lining the pipe under the road to the county connection. The team added people for and worked late on the second day. Job done on day 3. The job took 3 days (as promised)."

"Tou did a great job with work if installment. BUT, I have not been informed that I need additional pieces needed to be installed for RELAC and they did next inspection and gave me pass certification.... is it reliable? This year RELAC people from Reston association came to tux the air condition issue that I had and they informed me that if I don’t have those pieces in the system, my house will get damaged and not good for my air quality. I contact Clover and they were not responsive and the response that they have given later was so unprofessional. I was happy with their service but finding this issue with my HVAC installation and their response made me decide not to work with them again. I thought that they were recommended with my Condo because they knew how RELAC work and the structure or how inspection passes. Obviously they don’t ... Thanks"

"Everything went very, very well.  CJ is knowledgeable and made the needed repair quickly and without any major disruption to the kitchen.  No clean-up was needed after he left.  I recommend WD Graves Plumbing and CJ for prompt, fairly-priced service.

FAQs for septic system installation and replacement projects in Ashburn, VA

The smallest standard septic system uses a 500-gallon tank, which costs between $875 and $1,150 installed. This size works well for single-occupant dwellings with minimal wastewater production. However, many local regulations specify minimum tank sizes, so check with your building department before committing to this compact option. Some jurisdictions require at least 750 gallons regardless of home size to ensure adequate waste processing capacity.

The installation timeline varies based on site conditions, permit processing, and contractor schedules. The process includes obtaining permits, conducting soil tests, excavation, tank placement, leach field construction, and final connections. Weather conditions, soil challenges, and inspection scheduling can all affect the overall timeline. It's wise to begin planning well in advance of when you need the system operational.

The most economical approach is to install a conventional anaerobic system with a plastic tank. To minimize costs while maintaining legality, obtain multiple quotes from licensed installers, consider scheduling during their slower seasons, and handle basic site preparation yourself. Never skip permits or required testing to save money—illegal installations can result in significant fines and mandatory removal, ultimately costing far more than doing it right initially.

Regular pumping helps prevent system failures and extends operational life. Most small systems require pumping every three to five years, though frequency depends on household size and usage patterns. Pumping services cost between $290 and $530, making this maintenance expense relatively minor compared to potential repair costs ranging from $500 to $2,600 for neglected systems. Establishing a regular maintenance schedule based on your installer's recommendations helps avoid costly emergency services.
