About

A&A Systems Control was founded in 1965 in Stamford, CT, incorporated later
in 1971 and purchased by the Palermo family in 1979.

Since 1979, Joseph Palermo and his family have been providing clients in Stamford, Greenwich, Darien, New Canaan, Westport, Weston, Easton, Fairfield, and Neighboring communities throughout Fairfield county and Westchester county with septic & drain services and excavation services for over 45 years.
Since our humble beginnings, A&A has always believed in the core principles of providing our clients with the best possible septic services at fair price and prioritizing customer service.
In 2023, the Palermo family made the executive decision to sell A&A Systems Control and partner with another CT based septic business that is also family owned and operated. In doing this we were able to expand our coverage area and provide clients with additional services and more support, this opportunity ensures clients we can continue to provide reliable service for existing and new clients moving into the future.

O’Hala Sanitation is now the parent company of A&A Systems Control.

Customer service,industry knowledge and quality craftsmanship have always been the key principles at A&A since our inception, so when finding the best choice to take care of our wonderful clients we felt O’Hala Sanitation was a natural fit. O’Hala Sanitation shares many of the same key principles and qualities that A&A always has..
O’Hala Sanitation is a local family owned and operated business that believes in offering clients the same excellent quality service that A&A always has.
Joe Palermo will be staying on board with A&A and O’Hala Sanitation and serve as the director of operations for Fairfield County. We are looking forward to continuing to service your properties as well as building new relationships with all our clients!
