Allied Septic And Drain LLC has been proudly serving customers since 1985, building a reputation for dependable service, honest work, and long-standing community relationships.

The company was originally founded in 1985 by Richard J. Laliberte, who established Allied Septic Service as a reliable name in septic and drain services. In 2002, the business was purchased by William (“Bill”) Trombly, who continued to grow the company while maintaining its commitment to quality workmanship and customer satisfaction.

In 2024, ownership transitioned once again—this time to David J. Burrill Sr. David is no stranger to Allied Septic Service; he worked alongside Bill for five years prior to purchasing the company. His hands-on experience, deep knowledge of the systems, and familiarity with customers ensure a smooth continuation of the company’s values and service standards.

Today, Allied Septic And Drain LLC is proudly family-owned and operated by David, alongside his wife and their children. Together, they bring a strong work ethic, personal accountability, and a genuine commitment to treating customers like neighbors—not numbers. We understand that septic and drain issues can be stressful and disruptive. That’s why we focus on clear communication, accurate diagnostics, and dependable solutions. From routine maintenance and inspections to repairs and emergency service, every job is handled with care, professionalism, and respect for your property.
