Objective:

Reuse of treated urban water for the greenhouse industry and environmental planning purposes

(1) Supplementation of surface water

1. Additional fresh water source

during periods of drought

2. Preventing salination

European water quality standards are taken into account

(2) Greenhouse water

Alternative for greenhouse water:

- High quality

- High quantity

- Always available

- No water buffer

Rainwater, groundwater, drinking water and surface water
