00:04 In a study conducted by the Mines and Geosciences Bureau,

00:06 which was opened in the entire Metro Manila,

00:08 the flood prone area is considered highly susceptible to flooding in 400 barangays.

00:14 In Metro Manila, the main flood control project is the pumping station.

00:20 The design of these is from the canals, estuaries, and other waterways.

00:26 The water should be directed to the pumping stations before it is released to rivers like Pasig River,

00:32 Paranaque River, San Juan River, and until the water is completely released to Manila Bay.

00:38 In other parts of Metro Manila, the water is directed to Manggahan Floodway,

00:45 which will bring water to Laguna Dibay, which serves as a water reservoir.

00:51 In total, there are 52 pumping stations in Manila.

00:56 The question is, why despite the existence of these, the flood continues?

01:04 According to the urban planner, Paolo Alcazaren,

01:10 the waterways in Metro Manila are outdated.

01:14 The capacity of these is only 15 millimeters of flood water.

01:19 But the rainwater last Thursday reached 85 millimeters.

01:24 We really need to be equal in the level of development.

01:28 And we need to project the level of development, type of development, complexity,

01:33 the density of development, how many housing units in the condominium complex.

01:42 Before, the area was supported by 20 families, now it's 2000.

01:49 These are our waterways before.

01:52 They are clean and used for transport.

01:55 The movement of goods and people is by canal, like Venice.

02:01 Bernham said that our waterways are like the canals of Venice.

02:07 What happened? We poured our canals, the others filled them,

02:12 made it real estate, and our drainage system was lost.

02:17 Our other pumps are 30 years old, but they are still operational, maintained by the MDA.

02:26 But our old pumps, although operational,

02:30 we cannot ensure the efficiency of 100 percent because of old age.

02:37 So, we have scheduled to rehabilitate them.

02:42 The waterways are outdated, and there are still many obstructions.

02:47 First is the garbage dump.

02:50 One of our goals there is the part of the San Juan River in Calentong, Mandaluyong City.

02:58 Here in Ilog na Kalutang, all kinds of garbage that you can think of,

03:03 this is the literal garbage river.

03:06 The situation here is not far from the Estero de Magdalena in Santa Cruz, Manila.

03:11 Garbage is flowing through the Estero.

03:15 Of course, you will clean it now.

03:20 When you come back tomorrow, there will be a lot of garbage.

03:22 It will be repeated.

03:24 Another reason for the damage of the waterways

03:29 are the informal settlers living next to it.

03:33 If they need to go to the river, they can go there.

03:36 They can do it here, but the damage is in the Estero.

03:40 According to the law, there should be no infrastructure

03:45 or house on any waterway within 15 to 20 meters.

03:50 But it is clear that in other places in Manila, this is not followed.

03:56 It is not just the informal settlers who throw garbage,

04:00 even the formal settlers and the establishments throw garbage there

04:04 because there is no policing, no fines,

04:09 we don't have a carrot and stick for them,

04:12 and people have no sense of civic consciousness.

04:16 They throw garbage, they think that there is no repercussion, but there is.

04:23 At present, more than 100,000 families live in these so-called waterways

04:29 which are also considered as danger zones.

04:32 When it comes to pumping stations, like the one in Pasay, Navotas, and Manila,

04:42 garbage dumps are still a problem.

04:44 That is why the waterways are almost not moving.

04:48 Because our informal settlers are standing on the water.

04:52 It is not just in the eastment.

04:53 As a problem, their solid waste is directly and indiscriminately dumped in the creek itself.

05:04 Aside from the pumping stations,

05:08 one of the biggest flood control projects in Metro Manila is the Blumenthrift Flood Interceptor Project.

05:14 This is a catchment area that is adjacent to the floodwater in Quezon City and Manila.

05:21 But until now, it is still not finished.

05:24 The worst is the rain that fell last Thursday.

05:31 Most of the floods are in Quezon City and Manila.

05:35 Aside from the problems faced by flood control projects in Metro Manila,

05:45 another one that Alcazaren is talking about, which is the flood zone, is the overdevelopment in Manila.

05:50 The supply, drainage, and power needs to be proportioned to the intensity of development.

05:58 That is the lack.

06:00 Local authorities want the development to be more intensive

06:05 because that is the sign of improvement in their cities.

06:08 But there is a need for infrastructure to support them.

06:14 And if this is the only place where the development is improved,

06:18 the surrounding development will be the only one to suffer.

06:22 That's why you need coordination with adjoining LGUs and with the region.

06:27 But the water is coming in.

06:29 One of Alcazaren's suggestions is the use of so-called purview cement for the roads in Metro Manila.

06:38 So all of that water can go into the cistern or into the gravel bed.

06:46 Under the Metro Manila Flood Control Management Project,

06:49 the government of the Philippines will borrow 500 million dollars

06:54 from the World Bank and the Asian Infrastructure Investment Bank

06:57 for the construction of various projects to solve the flood problem.

07:02 Like the construction of a dam in the Upper Marikina River Catchment Area.

07:07 Improvement of urban drainage.

07:09 Modernization of Metro Manila pumping stations.

07:12 And improvement of flood forecasting.

07:14 All of the projects or programs that we will implement in Metro Manila

07:20 will be in accordance with the Flood Management Master Plan of Metro Manila.

07:25 The purpose of this project is to modernize the drainage area

07:30 in the priority flood prone areas of Metro Manila.

07:34 In the report released by the Commission on Audit for the MMDA last year,

07:38 from 2014 to 2016, the total project cost of flood control and sewage projects in the National Capital Region reached almost 800 million pesos.

07:50 And from 2014 to 2016, the total cost of flood control projects reached 168 million pesos

08:00 that were not completed within specific contract time and required completion.
