Environmental activists and Ludhiana residents have developed a citizen-led roadmap to revive the Buddha Nullah, aiming to restore the Buddha Darya river and address the groundwater crisis. The plan proposes reusing treated wastewater for irrigation and to maintain river flow. However, concerns are raised about reusing treated industrial wastewater near the Mattewara forest due to potential contamination and the inadequacy of current treatment plants. Activists advocate for strict zero liquid discharge norms for industries.
