Community Center Step Sewer System – 1st Review
Mr. Holcomb:
The City of Yelm has completed the initial review of the proposed Community Center Step Tank. Your application included:
Construction documents
Step Sewer Sizing Calculations
We have reviewed the plans for compliance with the City of Yelm Development Guidelines, the DOE Criteria for Sewage Works and general standards of civil engineering practice. The following
comments need to be addressed before the plans may be approved for construction. Our comments are summarized below:
Step Sewer Design:
There can be no 90 degree ells installed in the side sewer going from the building to the tank.
All STEP tanks over 3000 gallons must be constructed of fiberglass.
There must be a hose bib within 50 feet of the STEP tank.
Service line must be sleeved under any side walks.
Please review and revise the plans to address the above referenced comments. Please contact me before resubmitting the plans for additional review. If you have any additional questions
or comments please do not hesitate to call or contact me at jimg@ci.yelm.wa.us.
Community Development Department
Respectfully,
Jim Gibson P.E.
