Three Bdrm Units:(22 units) x (3 bdrm/unit)x110gpd/bdrm=7,260 gpd
Office Space: 4 Employees x 15 gpd = 60 gpd
Total = 16,340 gpd

Peak Hourly Flow (Sanitary): 16,340 gpd x Peak Factor
Total Population=[(24x1)+(29x2)+(22x3)]x2 people per bedroom=
=148x2= 296People (assume 2 people per bedroom)+4 office employees=300. P = 0.300 (in
thousands)
Peaking Factor = (18 + √P) / (4+√P) = (18+0.548)/(4+0.548)=4.08
Peak Sanitary Demand =16,340x 4.08 =  66,667 gpd
  0.06667 MGD
  (0.10 CFS)

Sanitary Demand Calculations:
Node 1 – Average 16,340 gpd (0.016 MGD)

Entire Site:
110-gal/d/unit x 1bdrmx24 units=2,640 gpd
+ 110-gal/d/unit x 2bdrmx29 units=6,380 gpd
+110-gal/d/unitx3bdrmx22 units=7,260 gpd
4 employees x 15 gpd=60 gpd
Site total= 16,340 gpd

Ave. Total = 16,340 gpd (0.016 MGD)
Assume 2 people per bedroom. 2 x 148 bedrooms = 296 people + 4 office employees = 300
people. P = 0.300 (in thousands)
Peaking Factor = (18 + √P) / (4+√P) = 4.08
Peak Sanitary Demand = 16,340 x 4.08 =  66,667 gpd
