Phnom Penh Flood Protection and Drainage Improvement Project Phase 4 which was built under a Japanese grant aid of US$36 million, was completed and officially put into use on 17 September.

Though equipped with the new flood protection system, Phnom Penh city can be still at risk of flooding during the heavy rainy reason if residents do not stop littering on the streets, as rubbish is the main cause of preventing the rainwater flow, said JICA during the project completion celebration, while urging all residents to keep the city clean.

The fourth phase of the project began construction in April 2019, and upon this completion, it will help reduce flooding by discharging rainwater faster than before, from around a 12-24 hour discharging period to less than a 2-hour period, through the new drainage pipes system.

The project covers the drainage system in the northern part of Wat Phnom and Tuol Kork, while the major works carried out in this project include:

1. The installation of a 12.2 km drainage system
2. The construction of a groundwater reservoir and pumping station in the public part in front of the CDC.
3. Installation of 6 mechanical machines (automatic garbage collection machine) at the gate of the pumping station.
4. Procurement of vehicles equipped with 2 pumps.
5. Assistance in starting work, operations, and maintenance.

Since 1998, JICA has been actively cooperating with Phnom Penh to reduce flooding issues, as it has successfully implemented the 4th phase of flood protection projects already covering the southeast, northeast and centre of the city.
