GENERAL
The purpose of Supplemental Amendment No. S is to perform transient analysis of
conveyance from the Phase 2 pump station to the BCRUA WTP to evaluate replacement
of the existing 24-inch diameter combination air valves (CAVs) installed at STA 68+00
and 163+00 on the existing Phase 1 raw water pipeline on Trails End Road.
BASIC SCOPE OF SERVICES
Task 7.0—Pump Station
Insert Task 7.3.4.1 as follows.
7.3.4.1 Perform simulations for a loss of power to the Phase 2 raw water pump
station to determine if the 24" CAVs at STA 68+00 and 163+00 can be
replaced with smaller diameter controlled venting vacuum relief valves.
The simulations will be performed with the surge control measures
recommended in the 2016 surge analysis report titled "Brushy Creek
Regional Utility Authority Raw Water Pump Station Hydraulic Transient
Analysis' dated May 26, 2016. Simulations will be repeated as necessary
to determine the minimum recommended diameter for the replacement
valves at these locations. Prepare a brief memorandum summarizing the

Hi Shay,
I've attached the signed Supplemental Agreement#5, so you (and NHC) are good to go!
I did speak to Sam, after you mentioned his concerns, and resolved any questions he had.
Please let me know if you need anything else.
