Testing Facilities

We’ve occupied the same piece of land in Holden, Massachusetts since the lab was first constructed. Since then, we have put to use the most current modern testing equipment and technologies.

Stormwater Testing Facilities

Our 10,000 square feet, state-of-the-art Stormwater Testing Facility employs both full-scale physical testing and Computational Fluid Dynamics (CFD) for stormwater manufactured Best Management Practice (BMP) design optimization and increased constituent removal efficiency. Our independent, third party testing help you verify that stormwater units meet regulatory requirements and protocols, including both the New Jersey Department of Environmental Protection (NJDEP) Laboratory Protocols for Hydrodynamic and Filtration devices and the Canadian Environmental Technology Verification Program (CETV) Procedure for Laboratory Testing of Oil-Grit Separators.

Our stormwater testing facility offers:

  • Full-scale (1:1) Testing
  • High Flow Capacities (~20 cfs)
  • Independent Compliance Testing
  • Sediment Removal Efficiency Testing
  • Hydraulic Characteristics Testing
  • Design Optimization
  • Real-time Video Documentation
  • Computerized Data Acquisition System
  • 45,000 gallon Supply Sump
  • Heated for Cold Weather Testing
  • High Capacity Filtration system (< 1micron)
  • In-house SSC Sample Analysis
  • Analysis of PSD, Constituents, etc.



Fisheries Testing

Using a variety of water supplies available, our fisheries testing and fish holding facilities can accommodate large numbers of freshwater, brackish water, and marine species for long periods in closed recirculating water systems.

One test apparatus is an 80-ft long, 6-ft deep, 6-ft wide recirculating flume. Velocities up to 3 ft/sec can be achieved over the full cross-sectional area. Typically, this flume is used for evaluating individual technologies testing species at a time.

We also maintain an even larger-scale fish testing facility comprising a recirculating flume in which we can install and evaluate fish protection technologies. The testing apparatus is 110 ft long, 20 ft wide, and 17 deep, and is located within a 10,000 square foot building. Two, 66-inch diameter bow thrusters, with a combined capacity of 500 ft3/s, move water through the test section. The area of the flume in which testing is conducted is about 80 ft long, 20 ft wide, and 10 ft deep. With an 8-ft water depth, the bow thrusters can provide a 3-ft/s test velocity over the entire 20-ft flume width. However, with a contraction installed, velocities up to 9 ft/s have been achieved.

The test flume has a 300,000 gallon storage tank with transfer pumps that convey water between the storage tank and the test flume. The test flume and storage tank have a water filter system and a large chiller to maintain appropriate water quality for testing with fish.

In addition to the test flumes, a turbine blade strike facility is available.


Additional Testing:

We also have the capacity and dedicated facilities for a slew of other testing options for numerous other industries, such as:

A test flume that is adaptable to simulate deep water wave propagation with the addition of a plunger type wave generator. Depending upon the period, linear waves as high as 9 inches can be generated.
