Submitted by sparwal on January 11, 2010 - 11:01
Hi
I stay in a condominium where we have 644 flats (3/4/5 bedroom), would like to know how to calculate minimum STP requirement to support our condo as per National Building Code 2005. Currently we have 400KLD STP plant (however flats occupancy is 70% only) but for last few months it not not functioning properly and daily need to pump out the sewage.
a) No of Person per flats
b) Minimum litre per person sewage contribution . Some where it says 135 litre and some there 200 litre.
Regards
Sandeep

1. Dear Sandeep, NCB 2005 has
Dear Sandeep,
NCB 2005 has given a guideline for different population categories in the metro cities - and for metro cities (population more than 100,000) it is taken anything between 150 to 200 lpcd (NBC Part 9, 4.1.1.1). In many Indian guidelines you can find a standard recommendation of 135 lpcd. In fact this figure is derived as follows:
The problem must be in the STP itself. Get it checked by a good Consultant; he can help you with the problem

2. Sewage and Effluent Treatment in cluster of Apartments
Dear Member,
You do not worry about all codes etc...At the start in design stage you would do all on standards and norms and regulations. As the time passes,as most people do not worry about O&M the problems starts to happen.
1. Ensure your STP is working fine, say the final effluent should be within 30-50ppm,
2. If is found higher always, than it is to be addressed, by having some add-on STP etc.
3. How big is your campus, 400 kl per day is 400,000 lits per day, this effluent water can irrigate all horticulture and peri-pheral greens etc.
Pl try to use the recycled water for flushing, garden-irrigation, and fire-fighting service etc..
We have done 6 projects on producing recyled water for varied uses in campuses etc..
Pl be in touch for details,

Dear Sandeep,
Your problem can be easily solved; you will have to apply bio-remediation further to the treatment already being done.
Please review the practices given in the ppt here:Vigyan Vijay PPT and write to me in order to ensure further progress.
