Waste Water Management
Problem Identification
Residential Water Use
Most Lebanese towns and villages have no wastewater infrastructure except for the traditional cesspools and septic tanks, which easily pollute the groundwater. Additionally, the water quality is unfavorably affected by industrial and agricultural wastewater. Moreover, industrial activities release a wide range of chemical effluents into watercourses, in particular affecting surface and coastal waters. That makes wastewater management one of the greatest headaches of Lebanese municipalities. Although Lebanon has a relatively favorable position regarding water resources in comparison to other countries in the Middle East, it is forecasted that it will face a water deficit within the next 10 to 15 years because of the mismanagement of accessible water and misuse of water resources. In numbers, Lebanon is estimated to generate 249M m3 of wastewater per year, enough to generate ….. m3 of fresh water! Consider using this amount of fresh water instead of consuming it from the resources… consider going Green!
Waste Water Management
How to go Green
Effective wastewater treatment is essential for protecting water resources and restoring water quality. Water deficit is constantly growing; the efficiency of water use must be improved. Treated wastewater is an alternative water resource and must be seriously considered as an option for satisfying consumers’ needs. We have started to invest in wastewater collection and treatment. Physical, chemical and biological methods are used to remove contaminants from waste-water. In order to achieve high levels of contaminant removal, and make the treated water efficient to be used, waste-water treatment procedures are combined into a variety of systems. The sludge resulting from this treatment is treated by various methods in order to reduce its water and organic content and become suitable for final disposal and reuse. Since agriculture is by far the largest consumer of water with around 70 % of water usage, and the demand for irrigation water is growing constantly, the treated water is to be used for irrigation. Renewable energy communities are hoping for cultural acceptance for water reuse, especially with the increase of agricultural practices, and the increasing pressure on limited water resources, so it can innovate new behavior to protecting these scarce resources, and be more environment-friendly.
