Suffering of Thirst in the Rain

It is a cruel irony to watch a city suffer from water rationing while standing in a tropical downpour. For years, the prevailing narrative in Iloilo City has been one of scarcity—that we simply do not have enough water to meet demand. However, a review of the data suggests that Iloilo does not have a resource problem; it has a management crisis. We are dying of thirst because we refuse to put out a bucket.

The preliminary calculations and numbers presented by the Institute of Contemporary Economics (ICE) reveal the staggering scale of our inefficiency. Iloilo City faces an estimated annual freshwater shortfall of 23,630 million liters. That figure sounds daunting until it is placed next to the city’s rainfall volume. Every year, approximately 174,314 million liters of rain falls within our catchment area. Yet, we capture and retain less than 20% of this natural bounty.

The result is a massive squandering of resources. We waste an estimated 145,114 million liters of potential water supply annually. To put that in perspective, the water we let wash away into the sea is more than six times the amount of water we actually lack. The scarcity is an illusion; the waste is the reality.

The government often hesitates to commit to infrastructure due to ballooning costs, but solving this specific crisis is a fiscal no-brainer. ICE’s preliminary proposal estimates that a functional retention solution would cost under PHP 1 billion – specifically PHP 920 million.

This low price tag is achieved through smart engineering rather than brute force. The initial reaction might be to build a dam large enough to store the entire 23,630 million liter annual shortfall, but that is unnecessary and expensive. Because it rains throughout the year, we do not need to store a year’s worth of water; we only need a buffer to cover the maximum monthly shortfall.

By building a pond (or series of ponds) with a capacity of just 2,000 million liters, we can bridge the gap. The cost breakdown is straightforward: PHP 120,000,000 for construction and PHP 800,000,000 for land acquisition. These figures are derived from US EPA cost benchmarks, adjusted by 62% to reflect local purchasing power parity. Relative to the billions spent on other infrastructure projects with vague returns, spending less than a billion to solve the city’s most pressing survival issue is a bargain.

There is a secondary, critical argument for this infrastructure: flood control. We currently treat rainwater as a threat to be flushed out to sea, but a retention system treats it as an asset to be banked.

Integrating these retention ponds with a rebuilt drainage system could reduce flood-causing rainfall runoff by up to 78%. This is a massive improvement for quality of life during standard wet months. We must be realistic, however; during the peak of the rainy season, the flood mitigation impact drops to between 8% and 11%. These ponds are not a silver bullet for super typhoons, but for the majority of the year, they offer a dual solution: reducing drainage stress while securing our water supply.

The only significant barrier is political, not technical. The report explicitly states that the 80 hectares of land required must be located outside Iloilo City. Attempting to acquire this land within the city limits is impossible due to availability and would cause costs to skyrocket by 5 to 10 times. Furthermore, the cost of building pipes from the ponds to treatment sites would fall on the water distribution utility, not the local government.

The solution is clear. We can continue to spend billions on piecemeal aid, or we can spend PHP 920 million to solve the problem at the source. The rain is falling. We just need to decide if we are smart enough to catch it.
