Existing problem

The tropical climate of Vietnam is a favorable condition for infestation of many kinds of pests including mosquitoes carrying dengue and malaria. The popular water-utilizing catch basin of wastewater collection system employs the principle of communicating vessels to prevent odor from sewers, therefore leaving water stagnant. Over time, the water turns mud releasing bad odor or becomes the breeding ground for mosquitoes.

The solution has low cost, easy installation but creates surprisingly great results especially in preventing odour and eliminating breeding environment of mosquitoes and other pets which was not addresses by existing solutions.
In the past, as rainfall was not drained quickly, bad smell was released. I had to cover catch basin mouth with rubber plate. After the odourless mosquito-free catch basin was installed in front of my house, rainfall is drained quickly leaving no smell. My family and the neighbours highly appreciate this solution.
The solution has a sound technology, simple construction and lower cost compared to other solutions having similar scale and purpose ... very suitable for building anew and upgrading existing catch basins to overcome their polluting shortcomings.
