The agency shall be fully responsible during this period, and under no circumstances should there be any leakage from the gates. If any leakage occurs, the agency will be held fully accountable. Even if the leakage is due to factors such as flow pressure, interference by outsiders (e.g., fishermen), or discharge flow, the agency will still be responsible. In such cases, the agency must immediately rectify the leakage with its own team and without any delay. The agency must also coordinate with departmental staff to maintain continuous watch and ward duties to ensure that no leakage occurs during the work period. If any leakage is observed at the gates, it must be stopped immediately without causing a drop in the pond level or wastage of Yamuna River water. Even if controlled discharge through the gates is necessary, the agency must still ensure the gates are made leak-proof without any delay or excuse during the work period.
