Industrial uses al so requi re peaki ng factors whi ch are greatly dependent on the type of industry bei ng served. We have assumed that i ndustri al water woul d requi re a 10-day peaking factor of 1.5. To establish a reasonable lower limit of design flow, we have assumed that it is desirable ,to plan for doubling of the Towaoc population as well as i ncreasi ng the use rate from around 94 gpcd to the previ ously establ i shed 200 gpcrl. In effect this would quadruple the total annual municipal water demand over the existing use. It is also assumed that adequate termial storage over and above fi re storage requi rements woul d allow desi gni ng for a lO-day peak. The annual municipal demand provided would be: Annual Water Volume = 266 people x 200 gal/person/day x 365 rlays 325,800 qal per af Annual Water Volume = 596 af This would be the municipal allocation and for a 10-day peaking factor would require a peak design flow of: 596 af x 2.02 = 1.66 cfs 724 af lefs 3-7 1060e
