Who We Are

SPF Water Engineering is an employee-owned regional water, wastewater, and hydrogeologic consulting firm. We have numerous repeat clients due to our reputation for providing good value, quick turn around, and cost-effective solutions. SPF (along with its predecessor firm, Scanlan Engineering) has provided water resource engineering and consulting services since 1994.


We seek to serve our growing client base with a high level of integrity, creative and cost-effective solutions, and high-quality service. We intend to always be an “employer of choice” in our industry. We will support and encourage efforts of our members and associates to build successful careers as engineers, consultants, and entrepreneurs.



Clients throughout the western United States, as well as the US territories of American Samoa and Puerto Rico, have called on SPF to assist them in solving their water resource and wastewater concerns. They know that SPF’s dedication to doing good work and delivering successful projects has no borders.

And the rest is... HISTORY
SPF Water Engineering traces its roots to the firm of Anderson & Kelly. Keith Anderson and Jack Kelly were consulting hydrogeologists (almost before there was such a thing) and engineers, working on ground-water projects throughout the western US. SPF’s “S” (Terry Scanlan) went to work for Anderson & Kelly, where he learned to apply his education in engineering and hydrogeology to practical problems. Terry eventually established Scanlan Engineering in 1994 to provide consulting services related to water resource engineering, wells, and water rights. Scanlan joined forces with two additional partners to form SPF in 2004. Christian Petrich (the "P" in SPF), previously the Associate Director of the Idaho Water Resources Research Institute (part of the University of Idaho), had conducted regional investigations of the Treasure Valley aquifer system and the Boise Front geothermal system just prior to co-founding SPF.
Since 2004, SPF has grown to be a leader in water and wastewater consulting in Idaho, and we are rapidly expanding, with clients and projects throughout the western United States. We strive every day to make decisions in the best interest of our clients and our staff. Our ability to do so is apparent in the fact that many of our clients have been working with us continuously for more than 20 years.
