Deer Springs City (Cont’d) 40% used in house (20% Depleted) 60% irrigation of lawns (65% Efficiency) Secondary Treatment – Sewage Effluent
Discharged to Stream How much of their effluent can they
reuse?

Deer Springs City (Cont’d)Current Depletion
((930)*.4*.2) + ((930) * .6 * .65) = 437.1 AFSewer Plant Discharge
(930) * .4 * .8 = 297.6 AFAllowable Reuse
640 – 437.1 = 202.9 AF
