751 Primary Lift Station Design Narrative &
p,.0
SE
18894
The 751 Primary LS provides for Duplex 85 HP submersible pumps capable of pumping under
several operating conditions. The pumps are rated at +1-1098 GPM at 116' TDH. This condition is
reflects all 3 LS sharing the 20" FM having (1) pump in operation. The State has confirmed this
scenario as the proper rating for the LS. Based upon run times shared by Water Mgmt for the
Stagecoach LS; the 751 Primary LS will also operate independently of the other lift stations based
upon observed cycle times.
Under the rated condition, all forcemains achieve a minimum of 2 FPS and 751 Primary has 6 cycles
per hour. When 751 Primary LS is operating independent of other LS (Scenario 1 A); the 20" shared
FM has a velocity of 1.7 FPS. This portion of the FM also receives over 6 hours of contributing flow
from the Stagecoach LS at velocities in excess of 3 FPS.
This design is based upon the City of Durham 2014 LS Design Standards with exception to the
allowance of submersible pumps (agreed upon with the City). All calculations are consistent with the
MDC for Permitting of Pump Stations and FM 03108
The LS discharges into an existing 12" FM permitted by others WQ 0039295. The 12" FM then
connects to the existing 20" Stagecoach LS FM at the intersection of NC 751 and Stagecoach Road.
From there the wastewater is conveyed directly to the South Durham WRF.
This permit is a zero -flow permit. City of Durham assigns wastewater flow with the gravity sewer
extension permits rather than with the LS permit. This LS is sized to accommodate 385,000 GPD of
domestic wastewater as outline on Page 2 of 5 in the FTA application (attached).

Ill. Certification Statement:
certify to the best of my knowledge that the addition of
the volume of wastewater to be permitted in this project has been evaluated along the route to the receiving
wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity
related sanitary sewer overflows or overburden any downstream pump station en route to the receiving
treatment plant under normal circumstances, given the implementation of the planned improvements
identified in the planning assessment where applicable. This analysis has been performed in accordance
with local established policies and procedures using the best available data. This certification applies to
those items listed above in Sections I and II plus all attached planning assessment addendums for which I
am the responsible party. Signature of this form certifies that the receiving collection system or treatment
works has adequate capacity to transport and treat the proposed new wastewater.

Subject: 751 South Primary LS fast track sewer extension application, WQ0041756
Hi Don and Mark,
We are reviewing the subject application. Just a couple of clarifications are needed before we draft the permit.
Item VI.7 of the application notes a flow of 385,100 gpd, but the narrative states this permit is a zero flow permit. It
appears the 385,100 gpd is existing flow, and there will be no new flow in this permit. Please confirm.
Item VIIIA of the application notes the pump capacity is 1098 gpm. The narrative notes the pumps are rated at 1188
gpm. Please confirm the pump capacity.
We'll start drafting the permit upon submittal and review of the above.
Thx

Ted: Sorry about that the pump rating is 1098 GPM. I have corrected the narrative and
Page 3 of the FTA (attached).
There is no flow associated with this permit.
Durham assigns flow thru the gravity sewer extension permits rather than on the LS
permit.
