At CMS, we are developing the infrastructure for the storage of rain-water and to replenish ground-water aquifers in all campuses. CMS is dedicated to store water to meet demand over time and to Recharge/ reclaim waste water or runoff water and restore/renew natural resources. City Montessori School launched Rainwater Harvesting Project at all its campus on Saturday, 21st July 2012. CMS observed Ground Water Week from 16-22 July in association with Ground Water Department of Uttar Pradesh and the company "Janus", to strengthen their commitment to work for the conservation of water in Lucknow. As a part of this event, CMS launched Rainwater Harvesting Project at most of its campuses, even though the main celebratory event was focused at their new branch in Gomti Nagar II.
