Navotas continues to find solutions to persistent flooding. Local government officials said they were not consulted on the significant aspects of the project, however. Check the timeline of the project here They saw the biggest irony - that the project was made for them and their people, but they were allegedly left out of the process. The costs are dire, as the project suffered from infirmities that experts warned may affect the effectiveness of the flood control project which took almost 10 years to be completed.

Watch: Sinking Cities Purple Romero reports: At the height of the southwest monsoon in August , this year-old riverwall in Malabon collapsed. It could have been avoided, if the right flood control project was put in place 13 years earlier in the flood-prone cities of Caloocan, Malabon, and Navotas.

Local government units were kept in the dark for most of the years the project was being developed. Navotas Rep. Toby Tiangco, who used to be mayor, says the lack of consultation led to a project with faulty design.

You have to put a riverwall or a dike in Malabon-Navotas river and Manila Bay, because if you only put a riverwall at one side only, water will come from the other side. Tiangco says the original design included a coastal dike. Tiangco: In the original design of the Camanava flood project, aside from the one to be constructed at the Malabon-Navotas side, there was also a coastal dike to be built by Manila bay.

But when they implemented the project, they removed the coastal dike because of lack of budget. By , the project was way behind schedule. How can we say if the design is right? But we think that being stakeholders, we should be provided with this information. The project has 26 components. Work started in DPWH project manager Carla Bartolo blames the delay on the difficulty of expropriating properties and removing informal settlers.

The DPWH was supposed to expropriate lots. By , it had paid for only To date, around Pmillion worth of properties have yet to to be paid for. We have paid most of the property owners. There are only a few left who have yet to be paid. We first negotiated, then they changed their minds. Most them have already been paid. Only a few were left. First they negotiated, then they changed their minds.

We only have to pay less than P20 million. The incomplete expropriation of properties proved costly. Because of unresolved right-of-way problems, several components were dropped from the original contract: remaining portions of polder dike in Malabon Malabon river channel improvement remaining portions of Longos Creek Channel improvement Estero de Maypajo Channel improvement Catmon creek channel improvement and the northern catmon drainage facilities By , the affected local governments insisted on their stake in the project.

Then Malabon Mayor Canuto Oreta formed an advisory council that would monitor and check why the flood control project remained unfinished. The council found that parts of the project design were flawed. The navigational gate -- which is supposed to control the sea water coming from Manila Bay and the outgoing water from the Navotas-Malabon river -- failed to operate in its test run in Bartolo blames it on the 4-meter debris that clogged the base.

Bartolo herself reported this to the Kamanava committee, but only in February — 4 years after the disastrous test run. Malabon initially planned to sue the DPWH in The Malabon city government says the national government also violated Republic Act or the Code of Conduct and Ethical Standards for Public Officials when it failed to release the documents requested by the local government within 15 days.

A legal case would have been complicated, so the local governments constructed their own flood mitigating structures. They used their own funds. Tiangco: In my early years as mayor, from , I saw that the project is already delayed. So what we did was we put up riverwalls. Despite the complaints over the first phase of the flood control project, the DPWH is set to start with phase 2.

These included the upgrade of the elevation of polder dike, Catmon creek rehabilitation, rehabilitation of riverwalls and construction of pumping station and floodgates. The DPWH is not even certain the project can withstand the effects of extreme weather or climate change. Its officials wash its hands of responsibility and blames the designers. They pegged the project for land use. In fact, Camanava officials fear that the design of the project is not only faulty, it has become obsolete.

Bautista: After Habagat, Camanava was severely underwater. He himself was convinced, he confirmed that there were lapses in the design. They are amenable that we can experience such calamity with a year floos-return period. But imagine [what] Ondoy was in , then 3 years after, we had Habagat. So the design is now obsolete. For 13 years, local officials demanded the truth about the Camanava flood control project.

When they finally got it, it was too late.

TIMELINE: The Camanava flood control project

Kajizshura What is wrong with Figures 1 and 2? Arcilla, MSc and Ph. This solution should be cheaper and could be integrated in the overall scheme of camqnava water management, resulting in a much lesser discharge of floodwater into the metropolis, which would reduce the kind and amount of intervention. To evaluate the effectiveness, the research team consulted the initial project prooject and hydrological and geotechnical studies to ascertain expected flood mitigation results, and evaluated them against site visit observations conducted in early August before and after torrential rainfall.

Design recalculation should incorporate floos subsidence caused by pressures from population growth, water usage, and urban planning. The proposed large dam flood control program is not designed properly because the flood model it is using is obviously substandard. The new models should recognize increased severity and frequency of hydrometeorological activity resulting from climate change, such as greater maximum high tides, rising sea levels, and increased magnitude and frequency of precipitation.
