To address rising flood risks and groundwater depletion, the Guwahati Municipal Corporation will launch citywide inspections this month to enforce rainwater harvesting and green space compliance. The move, backed by state building bylaws, targets widespread violations across residential, commercial, and institutional properties, aiming to boost urban climate resilience through ecological accountability and sustainable infrastructure upgrades.
The civic action stems from mounting evidence that unregulated urbanisation is contributing directly to the city’s chronic flooding and dwindling water tables. The directive, issued by the Department of Housing and Urban Affairs, calls for strict enforcement of the Guwahati Building Construction (Regulations) Bylaws, 2014, and the Assam Unified Building Construction (Regulation) Bylaws, 2022. According to these regulations, all residential, industrial, commercial and educational buildings must have operational rainwater harvesting structures and preserve mandatory green zones. Yet, inspections and civic reports have exposed an alarming pattern of non-compliance. In many buildings, percolation pits are either missing or badly maintained. Green areas—meant to cover at least 20% of every plot—are routinely compromised, often repurposed for unauthorised extensions.
Officials from the municipal body warn that continued neglect of these regulations could leave Guwahati further exposed to erratic rainfall and drainage failures. “When you seal the ground with concrete and offer no path for water to return underground, you trigger floods on the surface and drought below,” explained a GMC assistant commissioner. “We’re not just enforcing a rule—we’re protecting the city’s future water security.” The rules do offer flexibility for affordable housing projects. If a developer allots at least 25% of the floor area for economically weaker sections, the green space requirement can be relaxed to 10%. However, even within these concessions, civic audits reveal persistent rule-bending. To back its mandate with action, the GMC is rolling out a comprehensive penalty framework. Properties found in violation may face fines, cancellation of occupancy certificates, sealing of premises, or legal action under the Guwahati Municipal Corporation Act, 2017.
At the same time, the civic body is taking proactive steps to support compliance among the city’s most vulnerable residents. The mayor confirmed that rainwater harvesting units will be installed at no cost in all government schools and in households belonging to economically weaker families. The goal, officials say, is not just enforcement—but inclusive transformation. Urban infrastructure experts have welcomed the move as a pivotal shift in Guwahati’s climate adaptation strategy. “This is a progressive policy with the right combination of carrots and sticks,” said a senior hydrologist familiar with municipal resilience planning. “If the civic body follows through with intent, it could become a benchmark for other cities in the Northeast and beyond.”
With climate change intensifying urban vulnerabilities, cities like Guwahati can no longer afford to sidestep sustainable regulations. By reclaiming green zones, harvesting precious rainfall, and embedding water equity into building codes, the city is charting a new course—one that places ecological justice at the centre of urban growth.
