RE: Belfair Valley Plaza, Sanitary Sewer Capacity
Dear Kim,
I have received the test results from Matt Lee of Aqua Test for
their August 1, 2002 inspection and have talked to him about
current flow rates for the `Shops" ion-site sanitary sewer
disposal system. It is our understanding that your current
restaurant located in Port Orchard utilizes approximately 800
gallons per day and that your proposed restaurant for the
1 Belfair Valley Plaza will be smaller- in..size. .
I
The sanitary sewer system was designed for a total flow of 3, 500
gallons per day with an effluent BOD design concentration of 200
mg/l.
Current flows are 11100 to 1, 200 gallons per day. The test
results for August 1, 2002 have an effluent concentration of
22.0 mg/l, which is 11% of the design capacity for the
drainfield. Flow rates are less than 34% of design capacity.
The sanitary sewer system has capacity .for this proposed
restaurant.
Please note that there are two sewer lines located in the back
of the shops as shown on the attached sketch. The line furthest
back, . closest to the back wall, is plumbed for the rest room
facilities. The other line, labeled •greywater" is for the
restaurant waste. All floor drains, sinks and grease traps
installed for the kitchen must be plumbed to the `greywater"
line.
