Re.: Ewing Irrigation (SP) -Site Plan
Sewer Service Letter
MBESI#: 1000-0136
Dear Erika:
(979) 693-3838. Prue (979) 693-2554 I~
This letter is intended to provide you information regarding the sewer demand for the Ewing
Irrigation site plan on Graham Road as you requested in your comment letter.
I will use the fixture unit method to determine the peak and average day sewer demands for
this site. The existing building is the only sewer generator on the site currently. There is one lavatory
and one toilet in the building. The total number of fixture units for these installations are as follows :
Fixture Tvoe Fixture Units/Each Number Total Fixture Units
Toilet (w/tank) 2.5 1 2.5
Bathroom Lavatory 1 1 1
Total: 3.5
3.5 Fixture Units corresponds to a peak flow of 3.5 gpm on systems without flush valves.
Assuming a peaking factor of 4 the average daily sewer flow is 0.875 gpm (assume 1 gpm). This
corresponds to a daily flow of 440 Hons assuming uniform distribution throughout the day.
If you have any questions or additional comments, please do not hesitate to let me know.
S~incerely, L ~~/Z-
J Robertson, P.E.
