Innovative Solutions for Onsite Systems

Revolutionizing Wastewater Management

Discover how SimTech Filter is transforming the onsite industry with cutting-edge products designed to enhance system efficiency and reliability.

Our Story

SimTech Filter believes in sharing our knowledge of the onsite industry to help others.  Our main mission is to provide quality products that use this knowledge to protect onsite systems, make them more efficient and easier to maintain.  SimTech is located in Boyne City, a small town in northern Michigan.  We evolved from a family business, Koteskey Bros Excavating, which performs installations and service on onsite systems as well as other excavation work.  This background and the fact that we still are involved in this work today allows us to approach onsite problems from the perspective of an installation and service company.  We use the products we make, giving us first hand feedback on their performance.  This helps us to make improvements and develop new products that work well in real life situations.  While SimTech designs are intended to be “simple technology” we do not cut any corners and we do our best to offer unique solutions for problem jobs.

Our History

After two decades of experience in installation and site consulting Gary Koteskey, Gene Brooks, and Arnold Koteskey founded SimTech Filter. Faced with the increasing failure of newly engineered pressure systems, they embarked on a mission to find a solution. Their extensive research and development led to the creation of the industry’s first pressure system filter, the STF-100, in 1998. Their pioneering work didn’t stop there; they continued to develop a range of products designed to safeguard and optimize onsite systems. In 2023 Anua took over the reins and has continued this legacy of innovation and dedication which drives SimTech Filter’s ongoing commitment to excellence.
