"Mike and his team are extremely responsive and professional. From the first contact to final installation for a large, complex septic system, it only took 2 weeks including all the permit and inspection. We are really grateful for finding Septic Advisor through Angie's list and hired him for our project. We cannot be happier! Highly recommended! Will definitely hire Mike again for any future needs."

"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."

"I hired atlas earthworks to put a driveway and parking lot in on a remote piece of land I purchased. He was easy to commute with and did a great job. I even added some work to the job and he finished ahead of schedule. He has nice equipment and an extremely positive attitude. It was a breath of fresh air to have an honest contractor."

FAQs for septic system installation and replacement projects in Durham, 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.
