Hynds Up-Flo™ Filter
The new direction in stormwater filtration is UP
Hynds Environmental’s Up-Flo™ Filter is the new standard in stormwater treatment.

Designed to meet the most stringent stormwater regulations by targeting a wide range of pollutants including gross debris, fine sediments, nutrients, metals, oils and grease, organics and bacteria, the Up-Flo™ Filter is a high rate, modular system that combines a patented upward flow path with a unique Drain Down system.

The multiple treatment capabilities of the Up-Flo™ Filter – settling, screening and filtration – make it the most effective and economical stormwater treatment system available.

From a simple retrofit application to standard manhole configurations or even large vault system installations, the Up-Flo™ Filter is the future of stormwater treatment.

The high removal efficiencies and inherent low headloss of the Hynds Up-Flo™ Filter allow for a small footprint making it a compact and economical solution for non-point source pollution.
From a simple retrofit application to standard manhole configurations or even large vault system installations, the Hynds Up-Flo™ Filter is the future of stormwater treatment.

Installation locations include:
  • Streets and roadways
  • Parking areas
  • New developments
  • Construction sites
  • Vehicle maintenance yards
  • Industrial and commercial facilities
  • Airports, truck stops, shopping malls, restaurants, supermarkets, etc.

The Hynds Up-Flo™ Filter can be applied equally well to new developments, urban retrofits or redevelopments and is an effective solution for targeting pollution upstream at its source. 

The Up-Flo™ Filter is sized to treat a specified treatment flow rate for a water quality design storm. Each individual filter module can be engineered to have an unprecedented treatment flow rate of up to 1.6 l/s or higher depending on the media combination and performance requirements. The number of modules will be determined by treatment objectives.

The flexibility of the system allows effective design for sites with low hydraulic drops. Hynds Environmental’s expert engineering team can assist in designing a system that is right for you.

Up-Flo™ Vault Systems

Hynds can design and build custom Up-Flo™ Vault systems to treat stormwater from small to very large runoff areas. The smallest vault system includes 12 Up-Flo™ filter modules while the largest can incorporate hundreds of individual modules. Manufactured from precast concrete components, the Up-Flo™ chambers are designed to satisfy all site constraints including structural loading, existing pipe depths and treatment performance.


The Hynds Up-Flo™ Filter has been designed to offer unrivalled performance in stormwater filtration. The system is designed to remove more than 90% of all particles larger than 40 microns (0.04mm) and 80% larger than 20 microns (0.02mm). The system also captures gross debris, nutrients, metals, oils and grease, organics and bacteria.
