Table 1.2
Wastewater per capita (exclusive of industry)
For example based on /2/,/3/,/4/,/5/,/6/,/7/,/8/.
Oct,av = Oyr/365 = (7.2 · 10 6 /(m 3 · yr))/(365 d/yr) = 19,700 m 3 /d
The hourly factor, th,d, is estimated at 15 h/d corresponding to an average town (see
Fig 1.6).
Oh,max = Oct,avlth,d = (19,700 m 3 /d)/(15 h/d) = 1,315 m 3 /h
