Delhi's clear air project aimed at providing safe zone: Govt
The project is directed at determining if the air quality index of a particular location can be lowered, officials said. If the study confirms both impact and practicality, similar 'Clean Air Zones' could be considered at Connaught Place, Khan Market and other high-footfall locations, they said.
'AQI (air quality index) is a big challenge in Delhi. We are conducting a study in Nehru Park…We are trying to determine if we can lower the AQI in a particular location. If this project is successful, this area will have nearly 50% lesser AQI than the rest of Delhi. When pollution is bad, doctors ask everyone to not go outside, in such a situation there should be an area where people can come for a walk or jog,' Sirsa said.
Sirsa said the devices—which can be up to nine feet tall—that primarily filter out particulate matter having a diameter of 2.5 microns or less (PM2.5), will be spread across the 85-acre park and maintain 'good' air quality even during peak pollution periods.
Each purifier will cover approximately 600 square metres and requires approval from the New Delhi Municipal Council before installation can begin, Sirsa had said on Friday.
Delhi grapples with hazardous air pollution levels that peak in the transition to winter. The move to install air purifiers follows the closure of two expensive smog towers that authorities deemed ineffective, after the then Aam Aadmi Party government touted them as a first-of-its-kind solution to the city's air crisis.
The new project will be carried out through a corporate social responsibility (CSR) partnership with private firm Umeandus, which has tested the technology at four locations, including Anand Vihar, at a petrol pump in Jangpura, New Moti Bagh and outside the Taj Ambassador hotel. Officials said each machine costs around ₹ 5 lakh and the project will be funded through CSR initiatives.
The initiative forms part of the Bharatiya Janata Party (BJP) government's broader air quality strategy, including its manifesto promise to halve Delhi's pollution levels by 2030.
Sirsa said, 'We are doing a lot of things to lower the AQI in Delhi. Very soon, Delhi will also see artificial rain, the efforts of which have been ongoing for nearly 10 years. Our government will achieve that in about four months.'
Earlier this month, the government also released a 'Mitigation Action Plan', featuring over 1,000 water sprinklers, 140 anti-smog guns, cloud seeding experiments, audits of pollution under control centres every six months, installation of automatic number plate recognition cameras at Delhi's border points for end-of-life vehicles, and inducting 5,000 additional electric buses.
A release from Sirsa's office said: 'This proposed initiative is part of Delhi's broader Environmental Action Plan 2025 which includes reviving long-pending artificial rain projects, daily mechanical sweeping, mist spraying, and enforcement of construction norms. Anti-smog guns have been made mandatory for large construction sites, and real-time compliance monitoring is underway. Legacy landfill bio-mining is actively progressing at Ghazipur, Bhalswa, and Okhla, aiming for permanent removal of hazardous waste.'
The field inspection at Nehru Park was conducted by Sirsa and Public Works Department (PWD) minister Pravesh Verma along with officials from the New Delhi Municipal Council (NDMC) and PWD.
'Since we have formed the government, our cabinet minister Manjinder Singh Sirsa and his department have taken many steps in lowering pollution and AQI in Delhi. Road infrastructure is also important for air quality. We have also requested a funding of ₹ 1,000 crore from the central government for this. We hope this fund will soon be released for new roads and flyover projects,' Verma said on Sunday.

Major Improvement In Water Quality Of Yamuna River In July: Minister
New Delhi: Environment Minister Manjinder Singh Sirsa on Saturday said the Delhi Pollution Control Committee (DPCC) has reported a significant improvement in the water quality of the Yamuna river in July, with key pollution indicators showing marked progress compared to June. Sirsa attributed the changes to sustained government efforts under the Yamuna cleaning program. "These improvements are not incidental or seasonal. They are the result of deliberate and sustained human effort," he said. The minister said that Rs 500 crore allocated for Yamuna cleaning is being used for upgrading sewage treatment plants, intercepting drains and preventing untreated discharges from entering the river. The DPCC collected water samples from eight monitoring locations, including Palla, Wazirabad, ISBT Bridge, ITO Bridge, Nizamuddin Bridge and Okhla Barrage, the government said in a statement. "According to the report, Biochemical Oxygen Demand (BOD) -- a key measure of organic pollution -- dropped sharply. At ITO Bridge, BOD levels fell from 70 mg/l in June to 20 mg/l in July. At Okhla Barrage, it declined from 46 mg/l to 8 mg/l," it added. Chemical Oxygen Demand (COD), another critical pollution indicator, also showed improvement. COD at ITO Bridge reduced from 186 mg/l to 54 mg/l and from 100 mg/l to 30 mg/l at Okhla Barrage, the government said. Dissolved Oxygen (DO) levels, which were near zero in parts of the river in June, increased significantly at locations like Palla and Wazirabad, suggesting better oxygenation. "We are not celebrating yet, but these results show our approach is working. The transformation of Delhi's environment is underway," the minister said. Sirsa also linked the progress on water quality to broader environmental gains under the Environment Action Plan 2025. Delhi recorded 29 out of 31 days in July with 'good' or 'satisfactory' air quality, making it the cleanest July on record.

Ludhiana: Dengue larvae detected in 23 schools, 61 houses
Dengue larvae have been found in 23 schools and 61 houses during a large-scale inspection drive conducted by the health department across Ludhiana district, officials said. The week-long campaign, led by 521 health teams, covered 851 schools and 29,747 houses. In total, 51,445 water-holding containers were inspected, of which 147 were found having dengue mosquito larvae. The drive is part of the health department's ongoing campaign titled 'Har Shukravaar – Dengue Te Vaar' (Every Friday – fight dengue). (HT Photo) The teams focused on high-risk areas such as school campuses, rooftops, overhead water tanks, air coolers, flower pots and vacant plots—common breeding grounds for mosquitoes. Dr Vivek Kataria, assistant civil surgeon, said, 'Finding mosquito larvae in educational institutions and homes is a serious concern. This underlines the urgent need for greater public awareness and participation. Dengue cannot be prevented by government initiatives alone. It requires consistent community action.' Immediate larvicide spraying was carried out in all locations where larvae were found, and strict cleanliness advisories were issued to the institutions and residents concerned. The drive is part of the health department's ongoing campaign titled 'Har Shukravaar – Dengue Te Vaar' (Every Friday – fight dengue), which urges citizens, schools, and offices to dedicate every Friday to cleaning their premises and eliminating stagnant water sources. District epidemiologist Dr Sheetal Narang said, 'The dengue mosquito breeds in clean, stagnant water and bites during the daytime. Cleaning all water sources at least once a week is essential. During this campaign, teams not only conducted inspections but also provided door-to-door awareness about prevention practices. Awareness remains the most powerful tool.'
