Sheet Note # 17 on sheet # C11.01 indicates that the existing STEP Tank behind to existing house is to be demolished. This tank along with all equipment within the tank (pump etc) belongs
to the City of Yelm and must be removed and delivered to the Sewer Department. The contractor will bare all costs associated with this including removal and disposal of septage from
within the tank.
Sheet # C31.01 shows the existing STEP Tank that serves the existing Dental Office being demolished. This tank is in use by the adjoining business as well and provisions need to be made
for disposal of sewage from this business if this tank is removed.
Sheet # C14.01 shows separate service lines leaving the new 8000 gallon STEP Tank. This should show only one 2” service line. Please see development guidelines.
The existing STEP Tank at Today’s dental is not H-20 Load bearing rated and must be protected. No parking over this tank.
Pump Control Panels for these 2 tanks need to be either mounted on a building or a remote post. If a remote post is used, the material must be “unistrut’
Hose bibs must be installed within 50’ of the pump end of each tank.
Submittals must be received and approved by the City of Yelm Sewer Department for this new tank.
The method of taping the existing Sewer main must be outlined.
Please show the Depth of Bury for this new tank.
