Integration of rainwater retention and

Include surfaces and elements able to infiltrate rainwater into the terrain both in public or community areas in new or renovation projects.<\/p>\n

Why?<\/strong><\/p>\n

– They reduce the risk of flooding by reducing the volumes of runoff.
\n– Increase groundwater resources through infiltration, and improve their quality, avoiding contamination of aquifers.
\n– They help to recover, increase or create ecosystems and habitats, favouring biodiversity.
\n– Improve the urban landscape, increasing the value of the areas where they are inserted.<\/p>\n

How?<\/strong><\/p>\n

01 BIOLOGICAL TREATMENTS (PHYTODEPURATION)
\nGreen filters or artificial wetlands<\/p>\n

These are natural purification systems for both runoff water and the drainage of small residential areas or camping sites (< 2000 inhab) and effluents from installations such as purifying plants, livestock installations, warehouses, etc., based on “irrigation”. Depending on the direction of the water they can be vertical or horizontal, but depending on the substrate and vegetation they are classified into: surface and horizontal flow, with macrophytes in flotation and floating species, or sub-surface flow.<\/p>\n

02 WETLANDS
\nThese are depressions in the ground or shallow reservoirs, covered with aquatic vegetation with a permanent sheet of water. They are designed to temporarily retain rainwater, allowing the sedimentation of suspended solids and the removal of contaminants through the intervention of vegetation (between 60-90% of contaminants).
\nTheir high infiltration capacity makes them appropriate where there are large volumes of runoff. They can be integrated both in new developments and in urban environments.

The first case is made of a surface detention tank where the grass Purifies the runoff. In the second example, the purifier consists of an anaerobic digester, a vertical subsurface flow wetland and 3 horizontal subsurface flow wetlands in parallel.<\/em><\/p>\n

This flow can sometimes come from other SUD systems or from the effluent of a WWTP.
\n– Low runoff velocities are needed to allow enough time for purification and infiltration.
\n– In 24 hours they must evacuate 100% of the runoff water, and it is required to consider a spillway as a safety system in the design.
\n– Maintenance must guarantee the elimination of solids, the regular cleaning of the entrance and exit of the system and the control of vegetation.[\/vc_column_text][vc_text_separator title=”EXAMPLES” color=”custom” style=”dotted” border_width=”2″ accent_color=”#fae699″][vc_column_text]La Gavia Park, Madrid.
