Real Science from Real Scientists:

Anyone you talk with at Aqua Sierra is a degree holding biologist, engineer, or scientist in a related field, not a random salesperson—a fact that we take immense pride in. We are a full-service aquatic consulting firm with fisheries, stream, lake, and pond management services—and we understand the critical nature of our work.

We know that creating effective solutions for water systems are complicated. Mis designing any solution or system produces poor results or may be a short-term patch supplying no long-term solution. A large percent of our new clients requests Aqua Sierra are to fix or upgrade failed equipment or systems provided by ignorant or unscrupulous vendors. Understand the quote from Benjamin Franklin, “THE BITTERNESS OF POOR QUALITY REMAINS LONG AFTER THE SWEETNESS OF A LOW PRICE IS FORGOTTEN.” We supply solutions, not band aids to solve our clients’ aquatic expectations and problems for the long-term.

Our clients expect an excellent ROI on their investments knowing our philosophy to service what our experts design, build, and install. We supply effective, custom solutions for each client. At Aqua Sierra, we are known for innovation in water treatment systems for streams, reservoirs, lakes, and ponds. These inventions include ozone enhanced aeration, beneficial bacterial injection, carbon active nutrient sequestration, and copper ion aquatic nuisance species control.

Our engineers and designers will strive to meet your fisheries and aquatic system management needs, expectations, and budget. Decades of project experience have taught us that planning, data collection, and accuracy at the start results in less costs, better results, and higher satisfaction for our clients overall.
