Criteria for GRIHA rating 83



Recycle, reuse, and recharge of water
Recycle and reuse of resources enables us to reduce pressure on our valuable natural resources.
Recycling of resources and putting these back into use for the building is signifi cant.

Criterion 20 Waste-water treatment


Objective
To provide facility for the treatment of waste-water generated in the building so as to have safe
disposal and use of by-products.

20.1 Commitment
20.1.1 Provide necessary treatment of waste water for achieving the desired concentrations for
disposal/reuse.
20.1.2 Carry out water testing for various parameters prescribed in the Pollution Control Acts,
Rules and notifi cations, CPCB, 1998, for disposal in surface water and on land or other reuse
application.

20.2 Compliance

20.2.1 Narrative on the type of treatment system being employed. Drawings with specifi cations of
the system indicating the capacity of water treated.
20.2.2 Indicate the quantum of treated water generated along with the use/disposal steps.
20.2.3 Provide the characteristics of waste water and expected characteristics after treatment from
the supplier.
20.2.4 Quality checking frequency and sampling plan of the treatment plant.
20.2.5 Narrative on disposal and reuse of other by – products such as sludge.

20.3 Appraisal (maximum points – 2)
20.3.1 Treated water should meet the disposal/reuse application standards (2 points).
