Can we raise this civic issue collectively? How?

Quick answer: Yes. You can: (1) Sign a petition together — many residents sign the same petition asking for the same outcome. (2) Lodge grievances individually but with the same description and ask for a joint response. (3) Raise it together at gram sabha or ward meeting. Collective action often gets better priority. Keep the tone respectful and factual. Our Petitions and Public Issues and Civic Participation doc have more.
