The value of the wastewater flow used for sewer design is the daily peak flow. This can be estimated as follows: q = k1 k2 Pw / 86 400 (2.1) where q = daily peak flow, l/s k1 = peak factor ( = daily peak flow divided by average daily flow) k2 = return factor ( = wastewater flow divided by water consumption) P = population served by length of sewer under consideration w = average water consumption, litres per person per day and 86 400 is the number of seconds in a day. A suitable design value for k1 for simplified sewerage is 1.8 and k2 may be taken as 0.85. Thus equation 2.1 becomes: q = 1.8 × 10 -5 Pw
