Based on the simple science of buoyancy, Thirsty Duck employs groundbreaking flow control technology that drains water at a constant rate — requiring less detention volume and therefore reducing stormwater system size by up to 50%. As a result, it makes regulation compliance less expensive and opens up usable land for additional development.

Maximized land

Thirsty Duck produces a constant flow rate, which requires less detention volume — shrinking stormwater systems by up to half the size — meaning you can free up more developable land.

Total compliance

Our product uses the principle of buoyancy to release water at a constant rate, with no mechanical parts and little to no maintenance, helping you meet regulations.

Lower expenses

Because our product helps minimize system volume, less land area is needed for ponds or vaults – saving money on raw land, reducing construction material costs and saving valuable time.


Can I get a permit?

Yes. Thirsty Duck is approved by multiple state DOTs and environmental regulatory agencies.


Will it clog?

There’s a chance any flow control solution will clog, but ours rarely does because it’s self-skimming and typically has larger openings than traditional technologies.


Has it been tested?

Yes. Thirsty Duck has been rigorously tested at the St. Anthony Falls Laboratory at the University of Minnesota, and there have been units in the field for over 10 years.


Is it difficult to install?

Not at all. It bolts right onto the outlet and requires simple tools. We’ll even send over a specialist to make sure everything goes well.


How much maintenance is involved?

Thirsty Ducks are designed to require no more maintenance than traditional solutions.


Will it survive time and weathering?

Our products are fabricated from the highest quality materials, specifically selected to withstand the stormwater system environment.


Is it used for new construction or retrofit applications?

It can and has been used for both.


Does it work for underground storage vaults and chambers?

Absolutely. It works in open ponds, underground vaults and manufactured chamber systems.


Will it work for my project?

We can customize Thirsty Duck for any implementation. See for yourself — send us your project for a complimentary, no-strings-attached design evaluation.


Will it actually save me money?

Our track record speaks for itself. Check out our case studies below.

The University of South Florida (USF) wanted to maximize the developmental potential of their Tampa campus because of their rapidly growing student population. But being constrained by four major roads that defined the campus perimeter, as well as increasingly stringent regulations, presented a challenging task.


We partnered with USF’s engineering team to optimize their stormwater system, using a Thirsty Duck. It resulted in a capacity increase equivalent to an additional 2.3 acres of directly connected impervious area (DCIA). This new developable land was not only an economic windfall, but more importantly, an opportunity to meet the needs of future students.

Reduced pond size in half for Toyota


Toyota of Lakewood, a new dealership in Bradenton, FL, made arrangements with their adjacent neighbor to construct a shared stormwater system that spanned both properties. Unfortunately, the neighbor was unable to successfully secure the required construction easements and agreements.


We delivered a custom Thirsty Duck with a peak, constant discharge rate of 19 cfs and was able to demonstrate a 50% reduction in the required surface area for the detention pond — allowing the dealership to construct the project entirely on its own land with no reduction in proposed impervious surface.

Maximized land use for WA communities


Stratford Court and Glennwick Grove, two residential communities in Northwest Washington, wanted to reduce the size of their stormwater vault detention systems — allowing them to save on building expenses and preserve valuable lot space.


By using Thirsty Duck, both Stratford Court and Glennwick Grove were able to reduce the size of their stormwater vault detention systems by 12,000 and 10,500 cu ft, respectively. As a result, the developments maximized land and reduced construction costs.

Avoided pond expansion for Bellingham Airport


The Bellingham International Airport, owned and operated by the Port of Bellingham Port Authority, received a grant from the FAA to convert a seven-acre wet stormwater detention pond to a dry one. It was all part of an effort to discourage waterfowl from inhabiting the pond area, which was located immediately next to the main runway.


While performing the necessary hydrologic and hydraulic analysis for the system conversion, the Port Authority included the entirety of its plans for future development. By incorporating a Thirsty Duck into the outfall design, we were able to demonstrate that the detention pond could in fact be converted — and also accommodate the ultimate build-out of the airport without the need for pond expansion.

Minimized pond footprint for McKechnie Field


McKechnie Field, the spring training facility of the Pittsburgh Pirates, underwent a dramatic renovation that required modifications to their stormwater system. The original pond was not designed to current water quality or quantity standards, which meant it would have had to be expanded.


Engineers looked to us for a solution that would maximize the efficiency of the discharge weir and minimize the footprint of the stormwater facility. So we installed a Thirsty Duck that produced a peak constant flow rate of 19.8 cfs, increasing stormwater vault capacity without sacrificing space for new features such as parking, fan seating or player facilities.
