The rainy season is about to start, and with it comes flooding. Flooding is a significant problem in a lot of cities in the Philippines. Trash accumulation in the drainage system is one of the root causes of flooding.
Another cause for flooding is the growing number of impervious layers in most cities. Most of the ground in developed areas is impervious materials. Runoff increases as we develop more areas of our environment. Lesser water infiltrates the soil.
The government has been implementing several measures to solve this problem despite its efforts to arrest this problem. Flooding continues to be a problem faced by most cities in the Philippines.
One solution the government can put in place is permeable concrete. Applying this to the city's road network will supplement the overburdened drainage. Porous concrete has been around since the 1800s. This technology has been used in several countries to complement their stormwater management.
A news article from GMA back in 2014 reported DPWH is implementing this technology in one of there projects. The project is a 22-year flood control project. If the project was successful, we could implement it in other cities with flooding problems. It will offer cities another flood control solution. Implementing this on our road will help solve flooding. It will also allow rainwater to recharge the underground water table.
