Municipal & Residential
Municipal & ResidentialThe municipal & residential sector drives a huge demand for modern water and sewage treatment systems in countries throughout the Asia-Pacific region and in particular China.
While in countries such as China, the large urban centers already have proper water treatment in place, in many areas outside of the big cities there is still no or no reliable water supply. Given the pollution of the rivers and surface water, the Chinese government has recently approved new legislation which stipulates much stricter sewage treatment.
