Who we are

The mission of SludgeHammer Group, Ltd. is to help solve the world’s wastewater treatment and reuse problems by providing safe, environmentally appropriate, efficient and effective microbial biotechnology for residential, community, industrial and marine use.

Corporate Leadership
The SludgeHammer Group’s Northern Michigan corporate headquarters is located for optimum manufacturing and distribution throughout the United States and internationally. Since 2001, our regional distributors and installers have served customers from California to Maine, Louisiana to New York and globally in Canada, Mexico, Europe, Latin America, Africa, China, Malaysia, Australia, Libya, New Guinea, New Zealand, Norway, Sweden, the British Virgin Islands and the Caribbean.


Inventor and President Dan Wickham, PhD, is based in northern California, served in the United States Navy and has practiced ecological research and science since 1972. He directed the Marine Aquaculture Facility of the University of California-Berkeley and continues to lead SludgeHammer to assure we stay at the forefront of wastewater biotechnology.

Buzz Jenks, who is no longer with us, helped to guide the company from the start. After serving in the United States Air Force, he graduated from Michigan State University and had accumulated over 35 years of experience in manufacturing, marketing and contracting. His focus was strategic—creating world-wide opportunities for SludgeHammer and he has been greatly missed.
