FAST -TRACK APPLICATION (FTA 10-14) - COVER LETTER
Re: Sylvan Creek Subdivision - Force main Modification WQ0011095
Lincoln County, North Carolina
Prepared by: Riyad Baroudi, PE
10/26/2021
Proposed Design flow from Pump Station #11:
Proposed Average Daily Flow = 118 homes X 400 GPD/home = 47,200 GPD
1 swimming pool/club house = 1,000 GPD
Ex. Flow = 173.9 GPM x 60 x 24 = 250,429 GPD
Total Average Daily Flow (ADF) = 298,629 GPD
Total Capacity of PS#11:545GPM/2.5=218 Avg GPM
218GPM x 60 x 24 = 313,920 Avg GPD
Total ADF/ Total Average Daily Capacity = 298,629/313,920 = 95% Capacity
Proposed Development:
Sylvan Creek Subdivision - Proposes the construction of 118 single family 5-
bedroom homes with a swimming pool and club house resulting in an average daily
flow of 48,200 gallons.
The sewer flow will travel via an 8" gravity sanitary sewer system to the existing
Lincoln County Public Works pump station #11 that is on the Sylvan Creek
Subdivision Property. The sewerage is them pumped via approximately 8,800 LF of
6" DIP force main to a manhole and then gravity flows to pump station #12.
The capacity of pump station #11 and the 6" force main was recently increased to
457 GPM peak flow by increasing the size of the pumps and replacing some of the
6" force main with a 12" gravity main. The addition of the Sylvan Creek Subdivision
increases the peak flow entering pump station #11 by 84.24 GPM for a total peak
flow of 541.24 GPM.
Our calculations show that replacing 3,779' of 6" force main with 2,449' of 10" force
main and 1,330' oft?" gravity c wgr wi re uce he friction losses enough to reach
a capacity of 545 GPM peak flow. The length of the replacement is from the south
side of the CSX railroad r/w to the beginning of the previously installed gravity flow
manhole (#110) along US Highway #16 business.
There will also be a need to relocate 275 LF of 6" force main vertically due to the
required grading for the subdivision construction.
The wastewater will be 100% domestic type waste.
