Pump Control Panels are not allowed on living spaces
Plans show concrete encasement where RW mainline crosses Water main. Would prefer sleaving.
If these tanks utilize duplex pumping systems, 2” service lines should be used.
Why is there a 11.25 degree bend in the mainline at sta. # 3+00?
Would it not be more prudent to use couplings to connect to the existing mainlines rather than tapping?
Please show the location of the proposed future 12” Sewer Mainline.
More detail is needed for the new location of the RW line that is to be relocated. Please show fittings etc.
An Air Release Assembly might be needed in the high point of the RW line between this project and the Yelm Creek X-ing. The Yelm Water Department should be consulted regarding this issue.
The Yelm Sewer Dept received this set of drawings on April 29 with a letter of transmittal requesting comments by May 2. This is not adequate time.
