We are a full service Excavation and Trucking Company with 30+ years of experience. Specializing in Complete Septic System Installation and Repair. New or Failing System we perform perk and have Design Engineers we work with your particular project. Demolition of any Building and removal of debris. We do not perform septic pump outs.

"Addendum to my last review: When the septic pump failed, we discovered how many corners were cut. Instead of a septic pump, a sump pump (for rainwater) was installed with the 1½ inch pipe joined to a 2 inch pipe to make it look like it was supposed to. There was no coupler on the pipe leading to the distribution box, necessitating cutting the pipe to get the sump pump out. No check valve. Do NOT use this guy."

"We had Tom come out for an estimate on a pool demolition, which he did give us a quote on, but more important is that he helped us rethink what could be done INSTEAD of demotion. He passed up the opportunity for a job, but gave our family back a treasured summer activity. If you need an HONEST assessment, call Sunshine."

FAQs for septic system installation and replacement projects in Coventry, CT

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.
