Reliable, robust, versatile, maintenance friendly 4th generation storage systems

Rigofill ST is an underground Modular Geocellular Stormwater Storage System, (highest void ration 96% on the market) used for Infiltration (soakaways), Retention/Attenuation (Rain Harvesting) storage tank applications.

The Rigofill ST and Rigofill ST-B storage systems offers consultants a reliable, robust, versatile, maintenance friendly 4th generation storage systems, which represent real innovation for the Australian Market. Rigofill ST and ST-B storage systems are extremely strong and have been designed to handle these kinds of loads up to HGV60/ 60t (green module ST) and HGV30/ 30t (black module ST-B) per m2 with a minimum design life of 50 years.

The Rigofill ST storage system fully complies with extremely robust European Standards and Specifications (CIRIA C680/ EURO Code) and is backed by third party testing accreditation from BBA.

The system is 100% accessible and inspectable inside the tanks for flushing & camera access purposes to comply with operations and maintenance regulations via an access shaft and an innovative crossed-shaped tunnel giving each module two axial four-dimensional inspection capability on each layer.

The integrated QuadroControl ST/ ST-B shaft system allows for unobstructed access “from above”. Camera dollies can easily be positioned to achieve optimum inspection results.

A comprehensive range of accessories makes the Rigofill ST/ST-B system a unique complete system for stormwater management.

Wrapped with a geotextile, the Rigofill geocellular units can be used as an underground infiltration, retention or attenuation facility. Wrapping the Rigofill modules with an impermeable membrane creates an underground storage facility. We will be happy to help you in calculating all the relevant parameters in order to design the best and most economical solution for your project.

Topic 1: Climate adaptation / spatial adaptation

As a result of the climate change, the number of heat waves, the frequency of extreme rainfalls, the intensity of heavy rainfalls and the periods of prolonged drought have been increasing sharply.

The chances of heat stress in the living environment are also increasing. The climate change calls for a change of mindset: climate-resistant and water-robust facilities must become a self-evident part of (re)developments. With over 30 years of worldwide experience in the field of stormwater management, FRÄNKISCHE can help you finding climate-adaptive measures for addressing the global problems.

Topic 2: Responsibility for stormwater management

Local authorities are responsible for the efficient treatment and management of stormwater; they are obliged to implement this responsibility for stormwater management in their wastewater treatment plans.

For more than 30 years, FRÄNKISCHE has been active worldwide in stormwater management, urban water resources and the drainage of roads and highways. Statics calculations, supporting with project drawings, infiltration calculations, installation advice on site – just a few of the topics FRÄNKISCHE has in mind by “full service”.
