In Short : The Delhi government plans to install solar panels over the 17 km Munak Canal to reduce water evaporation, generate clean energy, and prevent pollution. Inspired by Gujarat’s canal-top model, the project aims to conserve water, enhance safety, and optimize land use. A detailed feasibility study is underway, with the initiative set to become a model for sustainable urban infrastructure.
In Detail : The Delhi government has unveiled plans to install solar panels over the 17-kilometre stretch of the Munak Canal. This innovative project aims to address multiple urban challenges, including water conservation, clean energy generation, and environmental protection. The initiative draws inspiration from Gujarat’s successful canal-top solar project.
Currently, the Munak Canal suffers from considerable water loss due to evaporation and seepage. Studies indicate that the Delhi Sub-Branch loses up to 30% of its water, while the Carrier Lined Channel records a 5% loss. Covering the canal with solar panels could significantly reduce these losses and improve water efficiency.
In addition to conserving water, the solar panels will generate renewable electricity for Delhi’s power grid. This approach utilizes unused canal airspace, thus saving valuable urban land and supporting the city’s transition to cleaner energy sources. It also offers a potential boost in solar panel efficiency due to the cooling effect of the flowing water below.
The project is still in the feasibility stage, with agencies like the Delhi Jal Board currently preparing a detailed project report and technical design. These studies will assess cost-effectiveness, engineering requirements, and environmental impacts before implementation begins.
Apart from energy and water savings, the initiative could improve public safety by preventing accidents and reducing illegal dumping in the canal. Installing panels on both sides of the canal—along 4-foot-high walls—is expected to act as a deterrent to trespassing and pollution.
Once finalized, the Munak Canal solar project could become a model for sustainable infrastructure in urban India. If successful, the concept may be replicated across other water bodies in Delhi, offering a blueprint for integrating renewable energy with smart water management.
