Noting that installing rainwater systems was their corporate social responsibility, a bench headed by NGT Chairperson Justice Swatanter Kumar directed these hospitals to pay the amount within one week for restoration of the environment.
It also directed these hospitals to carry all the rectifications and ensure that the rainwater harvesting systems operate satisfactorily and to their optimum capacity.
"One fact which cannot be disputed is that all these hospitals are operating for years and have not cared to install the systems required.
"It is unfortunate that even the biggest hospitals of Delhi have not cared to take the steps in the interest of environment and protection of the groundwater," it said.
The bench, however, did not impose any fine on Deen Dayal Upadhya Hospital, saying that it is a government hospital but directed action against hospital officials responsible for maintenance of rainwater harvesting systems.
