Green Roof Water Recycling System

Irrigation in living walls and green roofs increases water supply demand and this can be accommodated by recycling greywater.

Green roof water recycling system.

The green living roofs were incorporated into the facility s design program to demonstrate the viability of this technology toward promoting environmental sustainability. The green roofs were similar in construction and their water recycling system except that one green roof roof 1 added the aerobically treated septic discharge onto the roof in addition to the recycling system. The green roof water recycling system grow uses semi aquatic plants to treat waste washing water which can then be reused for activities such as flushing the toilet. As a roof type that requires frequent maintenance intensive systems can be thought of as gardens on a roof in contrast with an extensive green roof there are almost unlimited possibilities.

Water quality can be improved when a green roof is installed on a building. The waterlillee system captures wastewater from the showers basins and washing machine and distributes it to the garden for irrigation. For example irrigation rates in vertical wetlands can be approximately 5 10 l m 2 per day which corresponds to the peak evapotranspiration rate for plants in summer revell and anda 2014.

Water usage and the green roof water recycling system. Many studies in europe and north america have shown that green roofs can improve the water quality of the stormwater that leaves a roof with vegetation and substrates on it. Topic green roofs also known as living roofs are a restorative and protective system applied to the roof of buildings or structures. This particular water catchment system is being used out in the desert for an earthbag home.

Moisture sensors measure when the garden is sufficiently watered and the system then diverts excess grey water to the wastewater network. Green roofs collect rainwater to later be reused to run specific facilities. During the initial build out of the water recycling facility in 2009 the construction team installed a green roof system that eventually failed to successfully develop. Essentially it is an extra vegetative layer on the roof of a building.

Chris tell us about your work. This system requires some maintenance from time to time these green roof systems lie between the extensive and the intensive and usually include a mix of plant types. It could be a diy project but would take a lot of know how. Grow is the brainchild of.
