Oplan Kontra Baha

A sustained, national flood-mitigation program — restoring the carrying capacity of waterways, drainage and flood facilities from ridge to reef, with live monitoring and coordinated response.

Why it exists

One national program against flood risk

Oplan Kontra Baha brings DPWH flood-control works, field operations and real-time situational awareness under one mission: keep people, roads and communities moving when the waters rise.

Flood-control worksDesilting, dredging and declogging restore waterways and drainage; pumping stations kept running.
Prepared communitiesCoordination with LGUs, DENR and MMDA, and assets staged where flood risk is highest.
Live operationsThe OKB Command Center joins field reports, flood monitoring and weather in one picture.

The program

Ano ang Oplan Kontra Baha (OKB)?

Ang Oplan Kontra Baha (OKB) ay isang panandaliang programa ng pamahalaan.

Layunin: siguraduhing may dadaluyan ang tubig baha.

Oplan Kontra Baha is a short-term government program with one goal: make sure floodwater always has somewhere to go.

Halimbawa · Examples

Paglilinis ng mga basura na nagbabara sa drainage — clearing garbage that clogs the drainage
Pagtanggal ng mga nakaharang sa daluyan ng tubig, partikular ang mga illegal structure — removing obstructions, especially illegal structures, from waterways
Pagpapalalim o pagpapaluwag (dredging) ng mga ilog — deepening and widening rivers by dredging
Pagsasaayos ng mga sirang pumping station — repairing damaged pumping stations

Paradigm shift

From building to maintaining

Flood control is no longer measured only by what is built, but by whether what exists keeps working.

Then (before)

Build · Expand · Deliver

Emphasis on new flood control construction: more capital, an investment phase
Progress measured by capital delivery
Maintenance treated as secondary
Gradual loss of system capacity due to siltation and obstruction

Now (moving forward)

Maintain · Preserve · Restore

Equal focus on sustaining existing systems
Operations and maintenance as core functions
Keeping structures reliable is integral to asset management
Restoration integrated into the asset lifecycle: an investment that is not maintained is an investment that fails
New construction guided by system performance

Challenges and solutions

What stops the water, and what clears it

1
Challenge
Clogged drainage and poor stormwater flow
Declogging of drainage systems
2
Challenge
Silted and reduced flow of waterways
Cleaning and dredging of waterways
3
Challenge
Non-operational pumping stations
Ensuring operability of pumping stations and deployment of mobile pumps
4
Challenge
Infrastructure blockages along waterways
Clearing of illegal and unnecessary structures along waterways
5
Challenge
Poor waste management
Implementing and enforcing efficient waste management policies
