Restore your urban lake's health with solar-powered aeration, lighting, and water quality monitoring — oxygenating the water, improving biodiversity, and making the lake a safe and beautiful public space for the whole community.

3–5 hours a week during the 4–6 week installation phase, then 2–3 hours a month for aeration checks, water quality monitoring, and stewardship reporting.
Apply and Assess the Lake's Condition
Submit your application through ChangeX with details about your lake — its size, current ecological condition, any existing restoration work underway, and the community group that will steward the solar system. A brief water quality assessment or lake survey (dissolved oxygen levels, visible algal growth, fish population) strengthens your application significantly. Nirmaan prioritises lakes where solar aeration will have maximum ecological impact and where a strong community steward group is already active.
Water Body Assessment and System Design
A Nirmaan environmental engineer visits your lake to assess its depth, size, existing ecological condition, and the best positions for floating solar panels and aeration equipment. They design a 3 kW system tailored to your lake's specific needs — whether that's surface aeration for oxygen improvement, submersible pumps for deeper circulation, or a combination with lakeside lighting. The design is reviewed with your lake restoration group and the relevant city authority before any equipment is ordered, ensuring full community and regulatory buy-in.
Install the Floating Solar and Aeration System
Nirmaan's installation team fits the floating solar platform, connects the DC aeration pumps and any lakeside lighting, and commissions the full system. Floating solar installation involves positioning panels on purpose-built pontoons, securing anchor points, and running waterproof cabling to the pump units. Installation typically takes two to three days. The team runs a full commissioning test confirming that aeration operates throughout daylight hours and that any lighting activates automatically at dusk. Your steward group witnesses commissioning and receives the full handover documentation.
Train Lake Stewards and Launch Monitoring
Your lake restoration group, fishing community representatives, and school club volunteers receive a practical training session covering daily visual checks on the aeration system, monthly water quality testing (dissolved oxygen, clarity, and odour), solar panel inspection and cleaning, and fault reporting to Nirmaan. Stewards receive a simple monitoring log and Nirmaan's support contact. School nature clubs are encouraged to integrate monthly water quality data into their environmental science activities, creating a citizen science dimension that deepens community connection to the lake's recovery.
Track Recovery and Advocate for the Lake
Each month, submit water quality readings, aeration uptime data, and energy generation figures to Nirmaan and ChangeX. Document changes in the lake — improved clarity, return of aquatic birds, healthier fish populations — and share these with your city authority, local media, and neighbouring community groups. A recovering urban lake powered by clean solar energy is one of the most visible and inspiring community environmental stories possible. Use your data and story to advocate for sustained lake restoration funding, expanded solar coverage, and protection of the water body from future encroachment and pollution.
