Company Profile

Hydro International Ltd is a global company that provides advanced products, services and expertise to help municipal, industrial and construction customers to improve their water management processes, increase operational performance and reduce environmental impact.  


With over 30 years of experience and a reputation for engineering excellence, businesses and public organisations all over the world rely on Hydro International products and services to reduce flood risk, improve water treatment and protect the environment from water pollution. 


Headquartered in Clevedon, UK, Hydro International has a network of over 80 distribution partners and serves customers in more than 40 countries.

Products and Services

The natural ability of the ground to absorb water is compromised by the construction of buildings, roads, footpaths and parking areas on previously undeveloped land. Stormwater runoff from impervious surfaces often carries a high pollutant load that has a detrimental effect on the bodies of water into which it discharges and places additional strain on end-of-pipe treatment plants. The problems associated with stormwater quantity and quality are becoming more apparent with increasing urbanisation and climate change. Therefore, there is also a drive to reduce the volume and environmental impact of runoff from existing sites under redevelopment.

To help mitigate these problems, water related legislation and guidance such as Planning Policy Statement No. 25 (PPS25) and the Water Framework Directive (WFD) require us to start tackling these issues. The Water Environment and Water Services (Scotland) Act (WEWS) and the Flood and Water Management Act (England and Wales) along with associated National SuDS Standards will require developers and authorities to consider SuDS (Sustainable Drainage Systems) as priority solutions rather than continue to employ conventional drainage systems.

The pioneer of advanced hydrodynamic vortex and complementary technologies, with a proven track record of over 30 years, Hydro International is the leading expert in stormwater management, providing efficient, cost-effective technologies to safeguard water quality and control and store flows.

 

Flow Control

h 

Hydro-Brake® Optimum

The Hydro-Brake® Optimum vortex flow control provides customised water quantity management for surface, foul or combined water across a wide range of flows and for a variety of applications.

Precision-engineered to meet site-specific flow, head and storage requirements, only the Hydro-Brake® Optimum leverages more than 30 years of vortex flow control expertise to deliver exceptional flood protection and sustainable drainage.

ss

The Hydro-Brake® Optimum has been independently certified by both the BBA and WRc giving engineers and adopting bodies confidence in both the performance characteristics of the device along with the durability/ longevity of the product itself.

 

 

hydrobrake floodHydro-Brake® Flood

Hydro-Brake® Flood provides large-scale protection at the watercourse level, preventing costly damage and disruption to residents, businesses and essential services.

Using precisely engineered vortex flow control technology, Hydro-Brake® Flood is the only flood protection system to benefit from our unrivalled legacy of engineering excellence and scientific rigour.

 

 

hydrobrake agileHydro-Brake® Agile

Where adequate on-site infiltration is not possible, flood risks must be mitigated by attenuating stormwater to result in adequate flood storage. The Hydro-Brake® Agile flow control delivers effective flow control for sites with highly constrained storage conditions.

 

 

 

 

 

 

hydrobrake orificeHydro-Brake® Orifice

The Hydro-Brake® Orifice flow control provides water quantity management for surface, foul or combined water at sites with generous discharge consents and low storage constraints.

A low-cost, low-complexity flow control, the Hydro-Brake® Orifice is ideal for development-scale sustainable drainage at sites with moderate flows and moderate storage options.

 

 

 

 

 

Hydrobrake chamber

 

Hydro-Brake®Chamber

Pre-Assembled Flow Control in a Manhole

The Hydro-Brake® Chamber comprises an easy to install, precast reinforced concrete chamber containing a ready fitted, bespoke Hydro-Brake Optimum™ flow control. The Hydro-Brake® Chamber is delivered to site ready for immediate installation.

As the Hydro-Brake® Optimum is already installed in the chamber complete with preformed benching (preformed benching with standard units only), installation is cut to a fraction of the time compared to conventional methods. Inlet hole(s) are cored or formed prior to delivery and are made to suit exact site requirements. A range of outlet pipe sizes are also available.

 


Storage and Infiltration

Stormbloc® Storage / Infiltration System

d

2Stormbloc® is an underground modular block type, geocellular structure for infiltration, soakaway and storage of stormwater and surface water.

An integral patented tunnel through each block provides easy access for CCTV inspection and maintenance.

Stormbloc® can be used as part of or all of a SuDS solution.  It can be used to reduce the land take of a SuDS pond or bioretention system, it can be installed under roads, parking areas and landscaped areas or be used to extend the capacity of a swale. 

 

sStormbloc® has been awarded BBA Certification. The BBA Certificate (No. 10/4795) confirms that the celluar design of Stormbloc® meets high product performance specifications and quality manufacturing standards, backed by physical testing witnessed by the BBA and auditing of the Stormbloc® production facilities.

Using a BBA certified Hydro-Brake Optimum™ flow control with Stormbloc® provides a BBA certified stormwater control package.

Stormbloc® can be used in conjunction with our Hydro-Brake Optimum™, Downstream Defender®, Up-Flo™ Filter or Hydro Filterra™ Bioretention System to provide a complete SuDS solution which includes flow control, storage / infiltration and treatment.

Stormcell® Storage System

s

Stormcell® is a low cost, underground storage system suitable for installation beneath roads, car parks and amenity areas and permits access for inspection.

Virtually maintenance free and more effective than conventional systems, Stormcell® is a high capacity stormwater storage system which can be designed to suit shallow, deep or irregular site requirements.

The Stormcell® system demonstrates a major potential reduction in planned maintenance due to the perforated distribution pipes running beneath the storage tank. Any silts, grits or debris are washed through the pipework during the ‘first flush’ rather than into the tank. The system is therefore effectively maintenance-free. The only part of the system requiring periodic inspection is the distribution pipework which can be easily accessed from the manhole and jetted/rodded in the event of any obstruction.

Stormcell® can be used in conjunction with our Hydro-Brake Optimum™, Downstream Defender®, Up-Flo™ Filter or Hydro Filterra™ Bioretention System to provide a complete SuDS solution which includes flow control, storage / infiltration and treatment.

 

Stormwater Treatment

Downstream Defender®

d

sefrThe Downstream Defender® is the most advanced hydrodynamic separator available for the removal of sediment, oil and floatables from stormwater runoff.

 

The Downstream Defender® is proven to be more efficient than other structural treatment devices in as little as half the footprint and is the only separator with internal components proven to prevent pollutant re-entrainment (washout).

 

 

Hydro Biofilter™
