2gH Solutions is the exclusive US representative for stormwater applications of the Hydrovex® line of products from Veolia Water Technologies Canada.  With over 10,000 installations across the USA and Canada, Veolia Water Technologies Canada is the leading manufacturer and supplier of flow control products to the stormwater industry in North America.

Passive Flow Control

The Hydrovex TTT is a membrane flow regulator and produces a nearly constant flow rate with increasing head depths up to 16 feet.  It has a corrosion resistant design, minimal head loss, and requires no on-site adjustment.
Hydrovex BW - Bending Weir
The Hydrovex BW Bending Weir is an optimized overflow weir, which is more efficient than a conventional static weir. It operates automatically without the aid of moving bearings or counterweights, providing a long service life.
The Hydrovex Flap Spring Loaded Weir is an optimized overflow weir, which is more efficient than a conventional static weir. It provides more efficient results at low heads, compared to the Hydrovex BW.
The Hydrovex ARS Air Regulated Siphon offers an excellent alternative to conventional overflow weirs. Storm overflow outfalls using air-regulated siphons are much smaller in size than those using conventional weirs.
Hydrovex VHV/SVHV - Vertical Vortex Regulator
The Hydrovex VHV and SVHV are vortex style flow regulators which grant precise flow regulation without the use of moving parts.  They allow for larger inlet and outlet openings compared to standard orifices.
The Hydrovex Pond is a vortex style flow regulator based on the Hydrovex VHV.  It is fitted with a vertical inlet pipe, thus operating in the vortex flow mode with very little head required. Easy and quick installation, with no adjustment required.
The Hydrovex IHV is a vortex style flow regulator that provides more precise flow throttling and control.  Available inlet diameters range from 4" to 40", allowing it to cover a large flow range with high accuracy.
The Hydrovex IHV Euro Style is a vortex style flow regulator designed to be installed in a wet well, and includes an emergency bypass cover.  Available inlet diameters range from 4" to 40", allowing it to cover a large flow range with high accuracy.
Hydrovex Clari - Regulated Outlet Slot
The Hydrovex Clari is a flow regulator that provides nearly constant flow regulation with no mechanically engaged parts.  It also acts as an underflow baffle and has a very small footprint.  

Active & Operable Flow Control

The Hydrovex FluidGate is an operable control valve that features a PVC and stainless steel construction that is low weight and compact.  
Hydrovex HHV-E - Vortex Driven Electronic Regulator
The Hydrovex HHV-E is a powered, vortex style flow regulator that uses a vortex regulator to precisely control flow by opening and closing a valve. It automatically increases flow to clear blockages. 
Hydrovex Turbo - Flow Regulator
The Hydrovex Turbo is a self-powered flow regulator that operates in a manner similar to the HHV-E. It is powered by the flow of water through the device.

Check Valves

The Hydrovex CCV is a circular check valve that uses a rubber flap.  The lightweight rubber reduces the headloss across the check valve, compared to a traditional metal flap.
Hydrovex LCV - Linear Check Valve
The Hydrovex LCV is a check valve shaped to prevent backflow through slots and overflow weirs.

Flow Measurement

Hydrovex Tipper - Flow Measuring Device
The Hydrovex Tipper is a flow measuring device. It works using the same tried and true technology as a tipping bucket rain gage, but can measure flows from 4 gpm to 80 gpm.  It is equipped with a mechanical counter, or can be equipped with a magnetic limit switch.
Hydrovex FluidWing - Profiled Overflow Weir
The Hydrovex FluidWing is an overflow weir with a precisely designed shape that allows for flow measurement at very low heads.

Gross Pollutant Separation

Hydrovex FluidScreen - Oscillating Static Screen
The Hydrovex Fluidscreen is a screen system for gross pollutant separation that provides a means to maintain flow in the event the screen becomes clogged or blocked.  This reduces the likelihood of upstream flooding in the event of blockage.
