RE: Wal-Mart – Project Number SPR-05-0091-YL
4nd Review of STEP Tank System
Dear Mike,
The City of Yelm has completed the third review of the proposed Wal-Mart Step Tank revisions. Your application included:
Construction Plans
We have reviewed the construction plans for compliance with the City of Yelm Development Guidelines, the Department of Ecology Criteria or Sewage Works Design Manual and National Electrical
Code.
Review Comments:
Include tie-down and footing details to be included on plans.
See attached detail for 6,000 gallon step tank.
Need to supply Yelm Sewer Dept. with full submittal on new proposed tank that includes:
Location of all (3) risers
Length of inlet “T” ‘down pipe’
Method of supporting inlet ‘T’
Invert elevation of inlet pipe
Elevation of top of traffic bearing cover over inlet to tank.
Method of supporting new outlet “T” in existing tank, as this “T” will need to be located below the existing riser.
Baffle in new tank to have 3, 6” holes located 40” above floor of tank, not 12” as shown.
Inlet and outlet “T” in both tanks to be extended up to top of tank, just below the risers.
A Fernco rubber adapter (or equal) should be installed in the pipe connecting these 2 tanks to prevent breakage due to any tank settling.
Please review the above comments and submit updated plans. If you have any additional questions or comments please do not hesitate to call or contact me at steveh@ci.yelm.wa.us.
