WASTEWATER FLOW SUMMARY
The project proposes to combine the three (3) subject parcels into one (1) parcel. The
site development proposes three separate buildings that include a financial institution at
the corner of Shelburne Rd and Swift St; a mixed-use building with frontage on Shelburne
Road with first floor commercial and three (3) residential dwelling units on the second
floor; and a multifamily residential building with 27 rental units on the eastern side of the
parcel. The following is a summary of existing and/or past flows and new proposed flows.
Existing/Past Wastewater Flows:
Bourne’s - 760 Shelburne Rd
Service Station with 8 fueling positions and a 2,100 sf convenience store
No historic information was found regarding water or wastewater allocations
Therefore, use existing ANR flows as follows:
2 employees/shift x 13 gpd/employee = 26 gpd
8 fueling hoses and public toilet x 125 gpd/hose = 1,000 gpd
Bourne’s - 31 Swift St
Mixed Use Building - 5,760 sf (1,500 sf auto service + 4,260 sf general office)
No information regarding water or wastewater allocations
Use 10 employees x 15 gpd/employee = 150 gpd
Pizza Hut - 764 Shelburne Rd
Restaurant Size = 100 seats
Documented Wastewater Allocation = 2,400 gpd
Total Existing/Past Wastewater Flow = 3,576 gpd
Proposed Wastewater Flows:
Financial Institution (corner of Swift & Shelburne)
Bank with 3,250 GFA and 10 employees (no showers)
10 employees x 15 gpd/employee = 150 gpd
Mixed-use Building (south of bank, fronting on Shelburne Road)
1st Floor Commercial:
Space for two commercial tenants
Commercial 1: 4 employees (no showers)
Commercial 2: 2 employees (no showers)
Use 6 employees x 15 gpd/employee = 90 gpd

2nd Floor Residential
(2) 2-bedroom units x 210 gpd/unit = 420 gpd
(1) 1-bedroom unit x 140 gpd/bedroom = 140 gpd
Multifamily Building
3 floors of Residential:
(27) 2-bedroom units x 210 gpd/unit = 5,670 gpd
Total Proposed Wastewater Flows = 6,470 gpd
Net increase in design flow = 6,470 gpd proposed flows – 3,576 gpd existing/past flows =
2,894 gpd.
Therefore, the requested allocation is for an increase of 2,894 gpd of wastewater flow.
