Greetings.
I am calculating PEC, in which its formula is the one of the pictures attached. I would like to find WWinhab and for now I only have volume of waste generated (in litre) and number of population in the selected year. How do I proceed my calculation in order to get WWinhab in unit of (litre/people/day)? Is my calculation correct (picture attached)?
Current data:
#population: 31.7 million
volume wastewater generated in 2016: 3.326 x 10^12 litre
period of wastewater generation: 365 days or 1 year
Thank you in advance!
sorry, the formulas you are using, where did you get them? What book are they in?
Domestic households produce an average of 200–300L of wastewater per person every day! The USEPA estimates average daily wastewater flows of approximately 50 to 70 gallons per person per day . This may vary a little from country to country depending upon the customs. You may average out with your country as the base.
Frederico Fonseca Silva : Is that the default value? Because I need to take into account population number as well.
A K Shyam : Yes, noted about that. I have incorporated the country's population and annual wastewater volume into the formula attached, along with my calculation. Is it correct?
Professor A. K. Shyam is correct. We need to separate the urban population from the rural population regarding the generation of wastewater volume. Here in Brazil I use, on average, 250 liters per person per day for urban areas and 100 liters per person per day for rural areas.
Back in 2000 we were using 225 l/pe-d for pe < 500

It looks as if per-capita water usage may not be differentiated between rural / urban.
WASTE WATER GENERATION VARIES FROM PLACE TO PLACE. IN INDIA, THE PER CAPITA CONSUMPTION OF A MIDDLE CLASS FAMILY IS 135 LPCD OF WATER FOR A MIDDLE INCOME GROUP. 80 TO 90 PERCENT OF THIS AMOUNT CAN BE TAKEN AS THE AMOUNT OF WASTE WATER GENERATED. IN HOT CLIMATE AREAS, THE WATER CONSUMPTION CAN GO AS HIGH AS 200 LPCD, CALCULATE ACCORDINGLY
THE NATIONAL AVERAGE IS 135 LPCD. IT CHANGES FROM PLACE TO PLACE DEPENDING ON TEMPERATURE CONDITIONS, STATUS OF LIVING, USE OF WATER, CLASS OF PEOPLE ETC. 80 TO 90 % OF THIS IS CONVERTED TO WASH WATER OR SEWAGE.
