02 9541 3500Proposed ASTM Standard for Stormwater Hydrodynamic Systems
Stormwater hydrodynamic systems help to prevent contamination caused by stormwater runoff by removing certain settable solids.
A new ASTM International standard is set to be implemented which will specify test material that has a common particle size distribution and can be used to test hydrodynamic systems.
The proposed standard ASTM WK39909, Specification for Surrogate Test Solids for Measuring Performance of Stormwater Treatment Devices, is currently being developed.
Adam Stevens is a research technician at CONTECH Engineered Solutions and a member of C27, which is the subcommittee working on the standard. Stevens said that the proposed standard will help make sure that different treatment systems meet designated benchmarks.
He added that the proposed standard will go towards ensuring that receiving waters are protected and restored.
The standard will be predominantly used by university laboratories that test manufacturers’ claims, independent labs, regulatory agencies that establish test protocols and hydrodynamic manufacturers.
