Urban stormwater may seriously impact the management and the quality of water resources.
We participate in research programs such as « Segteup » program (system to manage and treat urban rainwaters) together with IRSTEA and developed turnkey treatment solutions for run-offs, from design (tailor-made to adapt to local rainfall volumes and variations) to construction.
Our customers are industrial companies, associations, property planners and developers who may be looking for an improved management of run-offs as well as communities requiring an appropriate treatment for combined sewer overflow in order to protect the environment from severe contamination.
Our «HYDR’EPUR®» solution for storage and treatment of stormwater discharges applies for :
- Rain water alone : run-off (car parks, roads, roofs, etc…)
- Combined Sewer Overflow
Syntea has more than 10 years of experience in this field. This enables us to guarantee a high quality discharge level.
Our system treats:
- hydrocarbons (PAH), heavy metals (zinc, copper) and suspended solids (SS)
- organic pollution (SS, COD, BOD5, TKN) from Combined Sewer Overflows.
A 3-stage method to retain the particle pollution and to treat dissolved pollution :
- Pre-treatment to retain coarse waste,
- A buffer zone for settling and storage of rainwater,
- A filtering/purification zone using a vertical flow reed bed filter.
Treated water is sent to the natural environment in compliance with local regulations requirements.
