The sanitation situation in the city and suburbs of Kuala Lumpur had deteriorated due to population increases, so we constructed sewage treatment plants with advanced treatment processes (4 plants) and a sludge treatment facility (one plant).
We not only constructed the facilities, but also transferred technology such as operation methods and maintenance management methods.

In the sewage treatment plants we introduce , our projects made it possible for existing oxidation ponds to be modified as modern sewage treatment facilities, and now cleaner treated water can be discharge into rivers.
