Answer:

Explanation:

Stage 1

Volume of liquid entering the tank each day

A = P × q

where

A = volume of liquid to be stored in the septic tank

 

P = number of people using the tank

 

q = sewage flow = 90% of the daily water consumption per person (Q).

q

= 0.9 × Q = 0.9 × 200

 

= 180 litres per person per day.

Therefore A = 8 × 180 = 1440 litres
