Phnom Penh’s public works and transport department, in cooperation with the Embassy of Japan in Cambodia, and Japan International Cooperation Agency (JICA), yesterday unveiled a mechanical screen which traps and removes garbage flowing in drainage pipes as part of the Project for Flood Protection and Drainage Improvement in Phnom Penh Capital City Phase IV.

The objective of the project is to minimise inundation and damage caused by rainfall by improving the drainage system and providing for emergency drainage works.

The Project for Flood Protection and Drainage Improvement in Phnom Penh Capital City Phase IV will be completed in 2021.

The mechanical screen is an automatic mechanical drilling system that helps to collect garbage in front of the drainage pipes at four pumping stations constructed in the JICA Flood Project Phase 2, according to the agency.

“Before installation of the mechanical screen, people were required to dive into the pit in order to remove the trapped garbage. This new screen will be able to eliminate the garbage automatically, and transfer the removed garbage by mechanical equipment,” said Ma Sopheavin, programme officer of the Water & Environment Section at JICA Cambodia’s Office.

“The new mechanical screen will contribute towards well-maintained city drainage, safer labour conditions as well as a cleaner water environment by eliminating garbage from wastewater,” she added.

Ms Sopheavin added that the mechanical equipment has been installed at four pumping stations in Chaktomuk, Preah Kanlong, Kandal market, and Old Market.

“When the project is completed, it can reduce the inundation flooding caused by heavy seasonal rain. The mechanical screen would also help the rain water to flow faster through eliminating garbage trapped in the drainage pipes. Thus, the duration of rainwater remaining on the road will be reduced from between 12 and 24 hours to just two hours,” she added.
