Skywater - Stormwater management solutions for cities to overcome floods and urban heat islands while reintroducing biodiversity.

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 recycle 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 period 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.
