Gallery Skywater & Sopranature 1


Skywater concept aims to achieve a "zero-rainwater-discharge level”

The Skywater concept also mitigates urban heat island effect thanks to measurable evapotranspiration properties; reuses rainwater for domestic uses and greenroofs irrigation to save drinking water; decreases the energy needed for air conditioning in summer; and recycles grey water for irrigation of green roofs. The "Skywater concept" includes the use of high potential evapotranspiration (PET) plants (instead of standard extensive sedums) for air cooling and stormwater retention: Sopranature® Fresh – an IOT technology for monitoring, measurement and management of the greenroof irrigation and water storage: Soprema Connect – Aqua; Rainwater discharge flow regulator: Slowli® – Stormwater performance calculator for roofs: Privilège – Proactive rainwater collection and buffer storage capacity on flat roofs, with interactive consideration of the weather events a/o forecast. The use of this water in dry periods for smart greenroof irrigation and/or cooling; The use of grey water resource, cleaned on flat roofs by phyto-purification process on the roofs and having high potential evapotranspiration (PET) properties.

Implementation Stories

Skywater & Sopranature by Soprema Group
Implemented by Pharmacie des Trèfles d'Or in Hésingue (France) in 2022

The pharmacist from the Pharmacie des Trèfles located in Hesingues in France commissioned Soprema to install a ‘traditional’ vegetation on his rooftop in 2022. As an experimental site, Soprema proposed to him the Sopranature Fresh Solution, some temperature sensors as well as other future Skywater systems which will be officially launched in early 2023 related to the optimization of water management.


Test is expected to measure the ability to retain water temporarily in the roof & urban cooling data


The environmental benefits

  • A temperature decrease of up to 4°C during heat waves (Lyon) at 1,50 m above the Sopranature® Fresh plants

The Financial benefits

  • Yearly water savings amounting to 730$
