Combatting Dust With Misting Tech
The Delhi Public Works Department (PWD) recently issued a tender to install a state‑of‑the‑art automatic water‑misting system along Rani Jhansi Road. Covering a stretch of approximately 2 km, the plan includes the deployment of 1,500 precision-engineered misting nozzles and complete control infrastructure.
Key Components & Coverage
The proposed system comprises high-pressure pumps, sensors, pipes, and 1,500 mist nozzles. These nozzles will emit a fine water mist designed to suppress airborne dust particles, especially PM10 and PM2.5, commonly generated by traffic congestion and construction.
Environmental & Health Benefits
The initiative aims to significantly reduce particulate pollution, improving air quality and lowering respiratory risks for commuters and nearby residents. By minimizing dust clouds, it also enhances visibility and traffic safety on this busy urban corridor.
Implementation Timeline & Tender Details
The tender has just been floated, seeking firms capable of providing end-to-end solutions—from design and procurement to installation and maintenance. The project is expected to commence later this year, with initial operations starting in the post-monsoon season, likely October‑November 2025.
Delhi’s Broader Environmental Push
This misting system joins several other pollution-control programs launched by the Delhi government, such as smog towers, odd-even traffic schemes, and extensive green belts—highlighting a strategic push to curb chronic smog levels.
