Our Water Problem Is Not What You Think It Is

The Philippines sits on roughly 226 billion cubic meters of water a year. That is a staggering number. And yet 12.4 million Filipinos still do not have access to safe water. The gap between those two facts tells you everything about what is really going wrong — and it is not that the country is running dry.

A new study from the Philippine Institute for Development Studies (PIDS), authored by Supervising Research Specialist Adrian D. Agbon, lays this out plainly. Across 532 water districts nationwide, annual demand exceeds effective supply by about 3.6 million cubic meters. The Visayas managed only 68 percent water coverage from 2019 to 2024, far below the 85 percent benchmark considered minimally adequate. Groundwater extraction along Iloilo City’s coastal areas has been flagged as a specific concern. The crisis, in short, is not one of resources. It is one of delivery.

Part of the reason is institutional. Around 30 government agencies share overlapping mandates over water quality, watershed management, irrigation, sanitation, and supply. That fragmentation delays permitting, stalls infrastructure investment, and leaves local water districts trying to serve growing populations with systems that have not kept pace. The PIDS study found that Luzon water districts source nearly 98 percent of their supply from wells. In the Visayas, that figure is about 60 percent. But here is the thing: groundwater extraction nationally rose by an average of 3.8 percent each year from 2014 to 2023, with a sharp 17.7 percent jump from 2019 to 2020 driven by mining, manufacturing, and construction. Nobody is coordinating how much is being pulled from the ground, or where.

For Iloilo City, the stakes are not abstract. Studies already found that wells nearest to the city’s coastal areas in Arevalo, Molo, Lapaz, and the city proper are experiencing saltwater intrusion, with the highest salinity reading recorded at 17.2 grams per liter — classified as very saline. A separate aquifer recharge study found that recharge at depths between 50 to 70 meters has decreased substantially, potentially threatening the city’s long-term water supply. The city has been tapping 93 percent of its supply from deep aquifers for years. Once saltwater gets into those formations, there is no practical way to reverse it. The water is gone.

And then there is the pricing question. Nearly all water districts use increasing block tariffs, where rates go up as consumption rises. Fair enough on paper. But the PIDS study warns that for low-income households sharing a single connection — a common arrangement in places like Iloilo — pooled consumption pushes them into higher-priced brackets. The poorest consumers end up paying more per cubic meter precisely because they can afford less. Meanwhile, about 30 percent of water produced never reaches a paying customer, lost to leaks, theft, or unbilled usage. The study flags the Uniform Price with Rebate model as a fairer alternative worth exploring. That conversation needs to happen at the local level, not just in policy papers.

A 2009 World Bank analysis of 35 water districts found something counterintuitive, too: integrated water systems actually underperformed smaller, non-integrated ones. Higher fixed costs and operational inefficiencies meant residents in those districts paid more while getting slower expansion of service connections. Bigger, in other words, is not automatically better. Scale without reform just scales the problems.

The Philippine Development Plan aims for 97.48 percent of Filipino families to have access to safe water by 2028. The Visayas sits at 68 percent coverage. Three hundred thirty-two municipalities remain classified as waterless. There is no realistic pathway to that target in the time remaining. Acknowledging that honestly is not defeatism — it is the only way to allocate resources where they are actually needed, rather than chasing numbers that look good on paper while communities across Panay and Negros Occidental keep waiting.

What would help? The study recommends integrated source-planning units at the provincial or regional level to coordinate groundwater and surface water allocation, a national groundwater monitoring network with open data access, source-protection zones around critical recharge areas, blended finance combining public grants with low-cost loans for infrastructure upgrades and leak reduction, and capacity-building for water district staff in hydrogeology, smart metering, non-revenue water reduction, and financial modeling. None of that is glamorous. All of it is necessary. Iloilo’s aquifers do not care about political timelines. They only respond to what we do — or fail to do — now.
