Rawalpindi Hit by Record 201mm Downpour as Punjab Prepares Four-Pronged Flood Plan

Rawalpindi and Islamabad faced one of the worst monsoon spells in recent memory as back-to-back rainfall events caused widespread flooding and pushed Nullah Lai to 22 feet, prompting emergency alerts across all agencies. Punjab authorities simultaneously announced a four-pronged infrastructure plan including check dams and ground storage tanks to shield the twin cities from future flood destruction.

130mm Rain Raises Flood Risk as Nullah Lai Hits 22 Feet

Torrential monsoon rain battered Rawalpindi in what meteorologists described as an extraordinary rainfall event, with the city recording 130mm of precipitation in a single spell — a figure that WASA officials confirmed crosses the 100mm threshold that marks a record-level downpour for the region. The surge pushed Nullah Lai, the city's principal stormwater channel, to a dangerous level of 22 feet, triggering evacuation advisories for low-lying neighbourhoods along its banks. WASA teams were deployed across the city to clear blocked drains and pump standing water from flooded underpasses, while residents in flood-prone localities were urged to move to higher ground. Emergency responders reported multiple road closures as rushing stormwater overwhelmed the drainage infrastructure. The district administration coordinated with NDMA and provincial disaster management units to pre-position rescue boats and relief supplies ahead of additional rainfall expected in the following 48 hours. Officials noted that the back-to-back nature of the monsoon spells this season had left soil fully saturated, meaning even moderate subsequent rainfall could produce outsized flooding in vulnerable neighbourhoods.

🤝 Rawalpindi Receives 201mm Rain; All Agencies Put on High Alert

Radio Pakistan reported that cumulative rainfall across Rawalpindi's weather stations reached 201mm in the season's most intense monsoon event, with individual gauges recording 186mm in New Katarian and 157mm in Golra, underscoring the uneven but severe distribution of precipitation across the district. The Civil Defence Department placed all emergency response agencies on high alert, with hospitals instructed to maintain surge capacity and district officers tasked with conducting welfare checks in the hardest-hit sectors. Power distribution companies suspended electricity supply in several low-lying areas as a precautionary measure to prevent electrocution risk from flooding. Schools in affected union councils were closed for two days as roads became impassable. The district coordination officer convened an emergency meeting with representatives from WASA, Rescue 1122, and the health department to streamline response. Citizens were advised to avoid unnecessary travel and to report any structural damage or stranded individuals to the district helpline. Officials praised volunteer groups who assisted elderly residents in evacuating ground-floor and basement dwellings near the Nullah. [3]

WASA Drafts Four-Pronged Plan to Tame Nullah Leh After Devastating Monsoon

In the wake of what authorities described as the fifth and most dangerous monsoon spell to strike Rawalpindi in recent years, the Water and Sanitation Agency presented a four-pronged infrastructure proposal to Punjab's provincial government aimed at permanently reducing flood risk along Nullah Leh and its tributaries. The plan includes the construction of a retention dam near the F-9 Park area, expansion of the nullah's channelised section through Rawalpindi city, installation of additional high-capacity pumping stations at critical overflow points, and a network of diversion channels to redirect peak flows away from densely populated sectors. A formal reference has been sent to the Punjab government requesting approval and funding. WASA officials told the Express Tribune that the dam option alone could absorb approximately 60 percent of peak flood volume during extreme monsoon events. Critics including opposition councillors argued the plan had been proposed before without action, and called for an independent audit of existing WASA infrastructure spending before new funds are committed. Residents in areas flooded multiple times this season expressed cautious optimism but demanded a timeline with accountability milestones. [2]

Punjab Approves Check Dams and Ground Storage Tanks for Rawalpindi

The Punjab government has approved a complementary package of smaller-scale interventions to work alongside the larger WASA flood plan, with officials announcing the construction of check dams on seasonal streams in the Islamabad Capital Territory fringe areas and a series of underground ground storage tanks in low-lying neighbourhoods of Rawalpindi that have repeatedly suffered inundation. The storage tanks are designed to temporarily hold excess runoff during peak rainfall events and slowly release it after the storm surge subsides, mimicking the function of a natural sponge. Engineers estimated each underground tank could protect roughly four to six adjacent residential blocks from the worst surface flooding. The check dams on upper streams aim to slow the velocity of runoff before it enters the Nullah system, buying critical minutes for downstream populations to respond. Punjab's irrigation minister said both initiatives were being expedited under an emergency procurement framework and that contracts would be awarded within 90 days. Community leaders in affected sectors welcomed the announcement but requested that ward-level committees be involved in site selection to ensure the infrastructure addresses the most persistently flooded zones rather than politically connected areas.
