At E. Garrity Water Solutions we focus on quality water improvements over quantity. We use our years of experience and expertise to complete your project with perfection. Customer service and honesty are the most important aspects of our business, and your satisfaction is guaranteed. Please call us today for an estimate. We look forward to working with you.

"For weeks, we were getting less and less water from our faucets. Finally, we were down to a dispiriting trickle. A first visit from Garrity did not resolve the issue. When, concerned, I called back several days later, they immediately dispatched Joe and Cody, who arrived w/n 15 min. They probed deeply to find out the cause, discovering a cracked pipe and failing well pump, dating from about 30 years ago. They installed a new pump and new well cap up to current code and ensured that the water coming from the well was bacteria-free. This am, Joe was back by 8 am to show us how to flush all chlorine residues from our system and explain what he had done. Joe was determined, undaunted and kept at it until he found the cause of the inadequate water pressure--despite the late evening hour yesterday. His explanations were informative, clear every step of the way and helped us understand what was going on. He was patient, amiable and very good at what he does. Thank you Joe, Cody and Garrity!"

"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. In addition to all their other fine qualities, the team at Great Bear is trustworthy! Could not ask for more."

Septic Tanks questions, answered by experts

A new water well pressure tank costs $300 to $500. If you choose to hire a plumber for the job, expect labor to cost $125 to $200. If the tank is difficult to access, labor will cost more. Diaphragm and bladder well pressure tanks have similar costs. One-compartment well pressure tanks are less costly, but they have a higher chance of waterlogging. Larger pressure tanks cost more and hold more water, but they don’t increase water pressure.

While the lifespan of your septic system will depend on a variety of factors, including how well you keep up with regular inspections and maintenance, it will eventually need replacement. Most septic tanks can last between 20 and 30 years, and under good circumstances, a septic drainage field may last up to 50. On average, though, about every 30 years or so, a major septic renovation will be necessary.

Although cesspits may be necessary depending on your main sewage system access or nearby soil quality, they carry a few drawbacks. Cesspools require regular emptying and have relatively high maintenance and pumping costs. Certain areas also disallow the use of cesspools and may require you to cover the cost of existing cesspools to be converted into septic tanks.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

When considering the price of drilling a well, factor in how much you’ll save in water costs per year. The average family of four uses 100 gallons of water per person per day in the U.S. With a private water well, you can save hundreds each year.

Wells are also environmentally friendly. You don’t need to worry about drinking water treated with chemicals. Talk to at least three well pump contractors in your area. They’ll be able to tell you more about your options, give you different quotes, and discuss the biggest concerns.
