System

Geocellular systems are versatile solutions for managing rainwater runoff, functioning as either RETENTION-INFILTRATION units or ATTENUATION units in standalone setups or within a Sustainable Urban Drainage Scheme (SuDS). Within SuDS, these systems are cost-effective, quick to deploy, and environmentally friendly, offering a smaller footprint with higher water collection and storage capacity than traditional systems. With a 50-year lifespan (Reference: Maximizing the Lifespan of Plastic Geocellular Drainage System) and reduced labor and machinery needs, they are a practical and popular choice for urban flood mitigation. Their rapid hydraulic intake and increased floodwater retention help reduce flooding and ponding in public spaces, giving municipal engineers additional time to drain excess water into the national system within capacity limits.

HYDROEX™ is pleased to introduce the HD Modular Geocellular Unit – a robust, flexible, durable, maintenance-free 4th-generation high-performance structural geocellular tank made from Virgin Polypropylene as per EN 17152-1 standards, or from Recycled material in full compliance with CIRIA guidelines and European norms. For detailed scope.

The two-part modular design of the HD Geocellular System also offers ease of installation, adaptability to limited spaces, and customization in length, width, and depth, enabling engineers to create configurations suited to specific site needs.

We at HYDROEX™ have developed a way to innovate traditional rainwater harvesting and make the system more effective. In line with CIRIA guidelines and other International Standards, as well as the principles of SuDS, we have developed a stormwater management solution that supports retention, infiltration, and rainwater harvesting.

The objective of the HYDROEX™ Storm Water Management Solution is to maintain or replicate the pre-development water cycle through design techniques that create a functionally equivalent hydrological landscape. When urban development occurs, the natural water cycle is altered to the extent that stormwater runoff from individual properties and roads intensifies, flows usually increase, and potential contaminants from residential and commercial activity and associated vehicle use flow into the streams and watercourses. Traditionally, stormwater generated from urban areas is conveyed efficiently to designed trunk drainage systems to reduce stormwater ponding and flooding risk.

The versatility of our technology has made this system suitable across a variety of projects such as schools, parks, hospitals, roads, bus depots, metros, ports, playground you name it, we've done it. By combining retention, infiltration, and rainwater harvesting practices, communities can mitigate the impacts of floods, alleviate water scarcity and drought, and promote sustainable water use while minimizing the strain on traditional water sources.

HD Filter and Separator

HD Modular Geocellular System has focused over the years on supplying Modular Tanks and Drainage Cells, in keeping with “turnkey” needs for developers and government.  

We are now able to supply our new Separator screens to be installed ‘in situ” build manholes, before water reaches our Modular Tanks.

System Benefits:

components11

Cost effective filtration system.

We can now supply a complete system of STAINLESS-STEEL screens to standard size or as specified by Engineers and Architects.

The separator does just that, it separates gross pollution or trash from the water entering to the Modular tanks.

It filtrates gross pollution or trash to 1000 2000 microns.

A secondary STAINLESS STEEL mesh screen filters water to 500 - 1000 microns at the entry point before water reaches the Modular Tank.

Only “dust like” particles smaller than 500 1000 micron will be entering the Modular Tank therefore the water in the Modular Tank i s very clean of gross pollutant or trash.

These STAINLESS-STEEL screens are supplied in many sizes for domestic and commercial needs.

The manhole is built “in situ” therefore it is easy and simple to install with Hydroex supplying only the screens and STAINLESS-STEEL runners for them.

Easily removable screens to be clean as required.

Applications

HD Drainage Cell System provides the ideal answer for sub-soil drainage applications that enable the creation of a successful Roof Garden without the worry of the usual issues related to cracking or leaking. The drainage cells offer a uniform surface and an internal void space for efficient drainage of extra water. They come with a special Diamond CUP construction that allows passive irrigation water retention and aids in creating a high-water table in the soil above profile so that vegetation can thrive during protracted dry seasons.
