Pakistan Wastes 35M Acre-Feet of Rainwater Yearly

Despite facing one of the world’s most severe water shortages, Pakistan wastes over 35 million acre-feet of rainwater every year, according to environmental experts. That’s enough water to refill Tarbela and Mangla dams multiple times — a staggering loss for a country battling droughts and food insecurity.

Heavy Rains, Poor Management

Every monsoon season, Pakistan receives abundant rainfall. Yet, due to poor water management, lack of storage infrastructure, and inefficient planning, most of this precious resource either flows into the sea or evaporates before it can be stored.

This wastage not only deprives the agriculture sector of much-needed irrigation water but also worsens urban flooding, especially in major cities like Karachi, Lahore, and Islamabad.

Experts say that with proper rainwater harvesting systems, Pakistan could store billions of gallons of water annually, reducing dependency on rapidly depleting groundwater reserves.

Climate Change Intensifies the Problem

With climate change causing unpredictable rainfall patterns, the country faces both flash floods and prolonged droughts — a dangerous double threat.
During heavy rains, excess water floods streets and farmlands, while in dry months, reservoirs run dangerously low, affecting food production and economic stability.

Environmentalists warn that without urgent action, Pakistan could face severe water scarcity in the coming decade, potentially threatening millions of livelihoods.

The Missed Potential of Rainwater Harvesting

Countries with similar rainfall levels, such as India and Sri Lanka, have successfully adopted rainwater harvesting systems at both urban and rural levels.
In contrast, Pakistan’s adoption rate remains low due to policy gaps, lack of awareness, and limited investment.

If harnessed properly, rainwater could:

• Replenish underground aquifers

• Support agriculture during dry spells

• Provide clean water for domestic and industrial use

• Reduce flood impact and stormwater runoff

Experts believe that even small-scale storage systems in cities and villages could collectively save millions of acre-feet of water annually.

Investing in Sustainable Water Infrastructure

To counter the crisis, Pakistan must prioritize small dams, rainwater harvesting in cities, and modern irrigation techniques like drip and sprinkler systems.
The government and private sector can collaborate to promote community-based water conservation projects, especially in drought-prone regions such as Balochistan and Sindh.

Public education is equally vital — citizens need to understand that every drop counts.
Water-saving practices in homes, industries, and farms can collectively make a significant difference.

Policy and Public Action Needed

Experts stress that the government must enforce strict water management policies, invest in research and development, and integrate rainwater harvesting into urban planning.
Without immediate measures, Pakistan’s population growth and rising water demand could push the country toward a full-scale water crisis by 2030.

Securing the Future

The wasted rainwater represents a missed opportunity for Pakistan’s progress.
By investing in water storage infrastructure, improving management systems, and promoting sustainable farming, the country can secure its future water supply and safeguard millions from water scarcity.

In the words of one water expert:

“Rain is not just a blessing — it’s an opportunity. Wasting it is a national loss we can no longer afford.”
