Water covers 71% of the Earth’s surface and it is vital for all known forms of life. On Earth, 96.5% of the planet’s water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation. Only 2.5% of the Earth’s water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth’s freshwater (0.003%) is contained within biological bodies and manufactured products.
The water industry provides drinking water and wastewater services (including sewage treatment) to households and industry. Water supply facilities include water wells, cisterns for rainwater harvesting, water supply networks, and water purification facilities, water tanks, water towers, water pipes including old aqueducts. Atmospheric water generators are in development.
In Water & Environment sector we deliver our engineering and development services in the following fields:
WATER & WASTEWATER TREATMENT
Water treatment is, collectively, the industrial-scale process that makes water more acceptable for an end-use, which may be drinking, industry, or medicine. Water treatment should remove existing water contaminants or so reduce their concentration that their water becomes fit for its desired end-use, which may be safely returning used water to the environment.
The processes involved in treating water for drinking purposes to provide a safe source of water supply may be solids separation using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation.
Wastewater treatment refers to the treatment of polluted water, where the pollution could be from human waste, industry, agricultural waste or other sources of pollution. Wastewater treatment is the process that removes the majority of the contaminants from wastewater or sewage and produces both a liquid effluent suitable for disposal to the natural environment and sludge.
In this sector, we deliver service packages of engineering, procurement, and construction in Water & Waste Water Treatment projects for industrial and municipal uses.
Safe drinking water is essential to humans and other lifeforms even though it provides no calories or organic nutrients. Access to safe drinking water has improved over the last decades in almost every part of the world, but approximately one billion people still lack access to safe water and over 2.5 billion lack accesses to adequate sanitation.
Water transmission systems play a key role in development of each country. In this sector, we deliver service packages of engineering, procurement, and construction for the following projects:
– Water Transmission Pipelines
– Water Transmission Channels
– Water Transmission Tunnels
Waste management is the generation, prevention, characterization, monitoring, treatment, handling, reuse and residual disposition of solid wastes. There are various types of solid waste including municipal (residential, institutional, commercial), agricultural, and special (health care, household hazardous wastes, sewage sludge). The term Waste usually relates to materials produced by human activity, and the process is generally undertaken to reduce their effect on health, the environment or aesthetics.
In this sector, we deliver service packages of project and construction management, engineering, procurement, and construction for the following solutions:
– Waste Incineration
– Waste – to – Energy
The natural environment encompasses all living and non-living things occurring naturally on Earth or some region thereof. It is an environment that encompasses the interaction of all living species. Climate, weather, and natural resources that affect human survival and economic activity are perceived as Environment.
The term environmental industry is defined as all revenue generation associated with environmental protection, assessment, compliance with environmental regulations, pollution control, waste management, remediation of contaminated property and the provision and delivery of environmental resources.
