Water can be released in a controlled way. Straightening the river speeds up the water so high volumes of water can pass through an area quickly.
Dredging makes the river deeper so it can hold more water. Raising the banks of a river means that it can hold more water. The floodwater flows into the relief channel and is taken either to an area where it can be absorbed, or re-enters the river further down its course. Hard engineering Flooding can cause damage to homes, businesses, infrastructure and communications. Dams and reservoirs A man-made reservoir.
In addition, as was clear again during Karding, solid waste clogs waterways and entrances to pumping stations. The social challenges presented are equally complex. Today, Metro Manila is home to about 15 million people. Around a fifth of the population consists of informal settler families, many of whom migrated from rural areas in search of better jobs. Informal settlers are particularly vulnerable to flooding, as a large percentage live in inadequate housing near waterways.
Implementation of the Master Plan cannot come quick enough for many people who suffered during Karding and lost whatever belongings they had. Listening to the stories of affected people is heartrending.

One such person is Lisa, who lives along a waterway and was evacuated when the water started overtopping the banks of the waterway. The tragedy took Lisa back to square one, and she has to build up her life and that of her children again from scratch. Every flood event brings thousands of stories like Lisa's, but there is hope. It is the first major activity to be implemented under the government's Master Plan. It is also the first Bank-supported project in the Philippines that benefits from co-financing from the Asian Infrastructure Investment Bank.
Through these components, the project aims to reduce flooding in about 56 drainage areas. At least 1.
Preventive flood risk management requires dependable pumping solutions. Under the first component, the project will construct new pumping stations and modernize existing ones, while improving the supporting infrastructure and associated drainage systems.
To fulfill the second component, solid waste management will be improved through better collection services, community awareness, and incentive-based programs. Improved collection will reduce the amount of solid waste that ends up in waterways, and thus at the pumping stations, significantly decreasing flood risk. The third component deals with resettlement.

City residents like Lisa whose houses are going to be impacted by the improvements of the drainage areas and the construction of new pumping stations, may need to relocate to safer areas. New types of rental support have been devised to provide resettled families with transitory and permanent housing close to their places of employment.
A rental subsidy program has been created to guarantee that resettlement options are affordable to all. And finally, working with Civil Society Organizations like Life Haven Center for Independent Living, will support people with disabilities who relocate and ensure they have full access to facilities and houses in resettlement sites.
Midwestern Flooding Isn’t a Natural Disaster
For every stage of the project, gender analytical tools will be used to make sure the needs of both females and males are addressed and monitored. Through consultations with women from various economic groups, surveys, and census, the team will generate gender-disaggregated data. Women will also play an important role in resettlement planning and livelihood restoration programs.
This project is an important step forward not only in flood risk management, but also in the social well-being and prosperity of the citizens of Manila.
The Metro Manila Flood Management Project is implementing innovative approaches to promote inclusive and resilient flood management. Read the original story here.
