We are doing a study for HUDA (Hyderabad Urban Development Authority) “Preparation of Environmental Building Guidelines for Hyderabad”. I am in the process of working out different economic options/models for decentralized waste water treatment in Hyderabad. Can you provide us the details on the different waste water treatment options available for the following building types.

a. Individual residential buildings

b. Group housing/apartments/gated communities/townships

c. Institutional/corporate/commercial buildings

I would also request to provide the information on the unit cost of construction and operation for each of the options given by you for the above building types

As part of the study, As these guidelines will be at city level for HUDA to incorporate in the building regulations, hence the information I requested in my question is per unit (KL/Cum) discharge of waste water for different types to building types.

The end use of this data will become part of our research outcome which we would be submitting to HUDA.
