Allied Septic & Drain LLC is based at 76 Maple Street in Manchester and handles septic pumping, inspections, maintenance, repairs, drain cleaning, sewer-line work, grease-trap service, and portable-toilet rentals across Southern New Hampshire. The company says it has served customers since 1985; its own history identifies Richard J. Laliberte as the founder, Bill Trombly as the owner from 2002, and David J. Burrill Sr. as the owner since 2024. The company describes itself as family-owned and operated by David, his wife, and their children.
Customers most often describe quick help when a septic system backs up or an event or jobsite needs a portable toilet. Recent reviews describe same-day or next-day response, emergency pumping, camera-assisted drain diagnosis, sewer lift-station cleaning, septic inspections, filter checks, and explanations of what the technician found. Reviewers also repeatedly mention clean, well-stocked portable units, clear communication, reasonable or competitive pricing, and technicians who leave work areas tidy. One homeowner described Allied arriving the next morning after finding an unexpected septic pit during foundation work, assessing the situation, giving advice, and not charging for a visit when no work was needed. Another described a same-day pump-out, diagnosis, and follow-up after a septic failure.
The company’s website advertises 24/7 emergency septic service, free quotes, pumping every two to three years, visual and full-dig inspections, septic repairs, hydro jetting, and grease-trap cleaning. Its service-area page lists communities throughout Southern New Hampshire, while BBB lists the Manchester address, an additional Newport location, David Burrill as owner, an A+ grade, and accreditation. The BBB profile says the business started locally in 2022, whereas the company’s own history says Allied Septic Service was founded in 1985; ask which entity or continuity the dates describe.
Allied looks suited to homeowners, businesses, municipalities, events, and construction sites needing septic or drain work, emergency response, or portable toilets. Before booking, confirm the scope, location, timing, and quote, especially for work outside its regular Southern New Hampshire service area.
