WATER AUDIT (SK SRI KELANA)
A) Hand wash
0.6 liter/3s = 0.2 liter/s
Wash hand times = 14.5 s
Water/hand wash = 2.9 liter
Assume 300 users x 3 times/day
900 x 2.9 liter = 2610 liter
B) Toilet
6 liter/flush
Users block c = 300 x 2/day
600 flushes = 3600 liter
6 liter/flush
Users block c = 300 x 2/day
600 flushes = 3600 liter
Total
Total/day = 5200 liter (5.2 units)
1 month = 20 days x 5.2 = 104 units
Cost 104 x RM1.37 =RM 142.48/month
RM 139 x 12 month = RM1709.76
Total/day = 5200 liter (5.2 units)
1 month = 20 days x 5.2 = 104 units
Cost 104 x RM1.37 =RM 142.48/month
RM 139 x 12 month = RM1709.76
