"Tim Mckinney was great. We started out with another company who charged an exorbitant amount just to locate the tank. Switched to Mckinney and it was really packed. He had to call in a water jet truck. His price including everything was only a few hundred more than the original company charged just to find it. He was so fair in his pricing. I definitely recommend him and will use McKinney in the future!"

"Couldn't be happier with the service we've been receiving from Great Bear Septic over the years. They are professional, take the time to answer our questions, and are unfailingly cheerful. They are a pleasure to work with. When we first purchased our home ten years ago, we had Earthcare take a look at our system. They tried to talk us into a $20,000+ replacement of our system. Something didn't seem quite right, so on the recommendation of friends, we reached out to Great Bear. Ten years later, with regular pumping from Great Bear, system still works great.

FAQs for septic system installation and replacement projects in New Windsor, NY

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.
