"Troy did a great job! My sister and I discovered that our dad, who has Alzheimerâ s and has caretakers living with him, had an overflowing septic system. Each time we had it pumped, we were informed that something was either blocked or not functioning properly. As a result, we needed to look into either completely replacing his leach field and septic system or finding someone who could help us. Troy was extremely helpful in this stressful situation. From the time I talked to him & hired him it was done within a week. Very happy!"

"I hired Jeff to replace my aging septic system. He walked me through all the steps, including finding the engineer for a new plan, setting up the inspections , finding someone to pump out the existing tank and finding an electrical contractor for the pump. (This was all during Covid .) He found ways to save money on the job like using my existing tank. His work met inspection and the new lawn he seeded came in great. Just recently, I had an issue with the exit pipe from my sump. I called Jeff, as the septic plan included moving the exit pipe for the sump pump. He came over promptly and repaired it at no charge to me, even though the breach may have been caused by a tree root. He is prompt, courteous and efficient. I highly recommend Jeff and his crew."

"My yard was a muddy mess, falling apart, and I was having to put more and more blocks under one side of my camper to keep it level. ASL Excavating came in and took a look and, not only complied with my needs and wants, but also gave some great suggestions, like placing an underdrain directly from my downspout sending all the water directly into a drainage gully. We also had a crushed stone pad placed for the camper parking, and along with the new grading it sits perfectly level, no blocking needed. Riprap was placed at the steep slope to prevent erosion. They also graded my driveway, prepping it for my next project, paving. They did the work 14 months ago and it looks as good as the day they finished. They were quick and appeared efficient with some nice technology. They had very little space to work and left no damage behind. Shane is the owner and a great guy to work with. He and his crew have a lot of experience and the pictures of their prior work sold me on hiring ASL Excavating."

"The price was a little expensive, but it was worth every penny. I chose the package with additional add on’s, because I wanted a comprehensive report. Tom was very thorough, professional, and knowledgeable. They saved me a ton of money by finding an issue with the septic system, that wasn’t easy to find. Tom was there for close to 4 hours and went over every aspect of the home with me in a walk through. I would highly recommend Main Choice and will definitely use them again in the future. Bill the owner was a very pleasant guy as well, and wasn’t afraid to roll his sleeves up and get dirty. Couldn’t have been happier with their services."

FAQs for septic system installation and replacement projects in Falmouth, ME

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.
