Best Septic Service was started in 1965 by Harold S. Colby in Concord, NH just as this industry was developed. New was the idea of septic maintenance as a preventative measure and Best Septic Service provided pumping and education to all the folks in and around Concord NH. Mr. Colby developed a huge portable toilet service that incorporated most of New Hampshire, including providing portable toilet rentals on top of Mt. Washington when they built the new Observatory/Museum in 1973. Mr. Colby retired in 1990 when he turned the reins over to employee Paul Johnson. In the '80s, Mr. Colby was a charter member of the NH Association of Septage Haulers to which Mr. Colby held several official positions. This association worked with the State of New Hampshire to develop statuary regulations to govern our industry and begin a longstanding educational program for homeowners. Paul and his wife Darlene continued Harold's dream of providing education to homeowners and protecting ground water through proper system operations. Best Septic has grown from one truck and one man to a 5 truck fleet. In 2010 Paul and Darlene will celebrate 20 years of offering septic maintenance and portable toilet rentals to the greater Concord area. Back then their two boys were strapped in to go along for the ride, now they both strap themselves into their own trucks as drivers for the company. The other employees have been with the company for over 8 years. Through the 20 years Paul and Darlene have been active community supporters of local youth programs, as well as drug awareness programs of their home town and many of the towns in their service area. Both Paul and Darlene have gone beyond just working in their own office, working on or with industry related associations such as the NH Association of Septage Haulers, National Association of Wastewater Transporters, Granite State Designers and Installers. Staying connected and educated about what the industry is doing. Darlene participates in several state and legislative appointed study committees where she has lent support and knowledge of the industry to legislators and state programs. As environmentalists, Paul and Darlene believe that the most environmental action is to complete the cycle of "re-cycling". True recycling is taking a waste (septage) product, cleaning it up in a favorable proactive way and then reusing it, such as putting back in the ground as fertilizer, the building up of loam and recharging aquifers. Paul and Darlene continue to work on projects that are developing septage disposal to do just that. Knowledgeable staffed office during working hours, 99% of the time to answer all your questions Prefer payment with service; we accept V,M/C AmExp click here to make a payment Clean trucks, clean uniforms, clean jobs. Drivers all have over 8 years of experience. We prefer not to go on your lawn, or across landscaping. We have enough hose, or can get enough hoses to do most jobs from driveways or street side. We back wash the contents the septic tank to remove 99% of the solids, leaving just about an inch of liquid on the bottom (to restart bacteria growth). It's empty. If homeowners are home, we will have someone flush inside, to assure the inlet line is free of obstruction. We inspect the tank, and the baffles (front and back) and note their condition, and can repair if necessary.
