Aquarius Systems, a division of D&D Products, is the oldest and most experienced manufacturer of surface water management equipment in the world.

In the 1950s, founder John Dauffenbach developed equipment to battle local aquatic weed problems. In 1964, John and his brother Doug incorporated D&D Products and expanded that early vision throughout the world.

Upon Doug and John's retirement in the 1990's, the business management and ownership transitioned to John's daughter, Jane Dauffenbach.  Together with brothers David and Jim and the rest of the talented staff, the company carries on with the tradition of engineering creative customized solutions for their customers who are based across the USA and in nearly 50 countries around the world.

Continual research and development has taken the equipment in this industry from its crude and cumbersome origins to the finely tuned machines available today. Through hands on management and state-of-the-art innovation, we are committed to providing high quality equipment, exceptional customer service and timely factory support.

Respected as the industry leader, our commitment to integrity is evident in every aspect of our business, from the outstanding quality of our equipment to the prompt, courteous people you’ll be working with.

We use the latest innovations in marine technology to achieve the ultimate in heavy duty design. All manufacturing takes place in our own 30,000 square foot (2,800 square meter) factory that was specially designed for the fabrication of water management equipment.

We are presently implementing ISO-9001 quality control standards for ISO certification. The engineering and computer aided design (CAD) departments are in house, giving us complete and immediate quality control over all of our products. Our engineering department is under the direction of a U.S. Coast Guard licensed Marine Engineer with over 22 years of experience in the marine and ship building industries.

With a fully stocked spare parts room and multiple courier stops per day, our aftermarket support is unrivaled. Additionally, our certified engine and hydraulics technicians are available 24 hours a day, 7 days a week for technical support.
