Lead and Copper
The addition of a new surface water treatment plant can have impacts on the corrosivity of the water and the release of lead and copper. As a result, your lead and copper monitoring
schedule has been changed. The system is now required to collect 20 lead and copper samples every six months starting as soon as the new treatment plant is in operation. The system is
also required to collect water quality parameter samples from two sample sites in the distribution system each month. Please choose from sites which are affected by the new treatment
plant. Unlike the lead and copper samples, these do not necessarily need to be collected from kitchen sinks and can be taken from total coliform sample sites. Please note pH and temperature
should be measured in the field. If you have any questions about lead and copper or water quality parameter samples, please contact the Division Lead and Copper Rule Manager, Dylan Martinez,

Jordanelle Special Service District Water System (UTAH#26086)
Fisher Ranch Water Treatment Plant (TP009)
The Division of Drinking Water (the Division) received a request for an Operating Permit for the Fisher Ranch Water Treatment Plant (WTP) project from your consultant, Nathan Rogers,
P.E. with Bowen Collins and Associates on July 23, 2025. Additional water chemistry data was submitted on August 19, 2025. The Division issued Plan Approval for this project on December
27, 2021. The project consists of the Fisher Ranch WTP (identified as TP009 in the Division’s database), the Provo River Intake (WS009) and the Fisher Ranch WTP Pump Station (PF016).
Project Summary
Our understanding of the project is the construction of a conventional surface water treatment plant to treat surface water from the Provo River. The finished water will be pumped (PF016)
from the WTP and conveyed through a 16-inch diameter transmission line to a 600,000-gallon tank (Mayflower Tank #4, ST022) and on to the distribution system.
In January 2019, Jordanelle Special Service District (SSD) started the preliminary evaluation process that led to the design of the Fisher Ranch WTP (TP009). The following provides a
summary of the history of the project:
Pilot testing protocol was submitted to the Division on May 6, 2020 and concurred with on May 22, 2020.
A 12-week pilot test was performed by Water Quality Technical Solutions using equipment from Intuitech using source water near the location of the proposed Provo River Intake (WS009)
from June 15, 2020 to September 1, 2020.
A Preliminary Design Evaluation Report including the Pilot Testing Results and recommendations was submitted to the Division on November 19, 2020.
An exception to Rule R309-525-11(9) Make up Water Supply Protection, R309-525-13(3) Sedimentation, R309-525-15(4) Media Design and R309-525-16(1) In Plant finished Drinking Water Storage
for the Fisher Ranch WTP (TP009) was reviewed and granted by the Division on December 3, 2021 (under Division File #12706).
The Division issued Plan Approval for the project on December 27, 2021.
The Fisher Ranch WTP (TP009) consists of conventional filtration and post-chlorination processes. The Fisher Ranch WTP (TP009) has a plant design capacity of 2,100 gallons per minute
(gpm). The design includes 4 trains of conventional filtration and each train of 700 gpm.
The treatment plant consists of the following processes in sequence:
Surface water from the Provo River will be diverted just downstream of the Jordanelle Dam through the Provo River Intake (WS009) structure and conveyed, by gravity, to the treatment
plant through a 42-inch diameter HDPE line.
Rapid mix, 2 stage flocculation and sedimentation through 48-inch-long, 60-degree tube settlers.
Chemical additions meeting NSF/ANSI 60 Standards:
Polyaluminum Chloride as the primary coagulant
Poly-DADMAC (T-Floc 1362 by Thatcher) as a coagulation/flocculation polymer
T-Floc 1465 by Thatcher as a filter aid polymer
Caustic Soda for pH adjustment on finished water
Compliance filter – AWC Water Solutions (AWC) dual media filter; 4 trains; 700 gallons per minute (gpm) per train.
Backwash water supply is from the finished water header on the high-pressure side of the pumps. Air scour is also included.
Post-chlorination – on-site generated 0.8% sodium hypochlorite solution
Disinfection CT:
Clearwell – a 200,000-gallon concrete tank located at the treatment plant with a baffling factor of 0.3.
Transmission Line – 246,729 gallons will be used for disinfection detention time (22,000-feet a 16-inch diameter transmission line) with baffling factor of 1. This transmission line
delivers water to a 600,000-gallon finished water storage tank (ST022) and no service connections will exist on this line.
Continuous analyzers are located on the clearwell pump discharge line and approximately 22,000 feet from the treatment plant on the 16-inch diameter transmission line to record free
chlorine residual, pH and temperature data for each of these two disinfection sequences.
Finished Water Pumps – two vertical turbine finished water pumps with a capacity of 1,400 gpm each and one jockey pump with a capacity of 350 gpm to deliver water from the clearwell
to the 600,000-gallon finished water storage tank (ST022).
Sludge Drying Basins – two concrete sludge drying basins contain backwash and filter-to-waste volumes plus the daily sludge wash-down. The basins allow for solids to settle at the bottom.
The decant water is taken off the top and metered back to the treatment plant raw water pipeline. Dried sludge is taken to the landfill for disposal.ADDENDUM 2Compliance Strategy for
Achieving Surface Water Treatment Goals
Jordanelle Special Service District (UTAH#26086)
Fisher Ranch Water Treatment Plant (TP009)Treatment Goals per Surface Water Treatment Rules
The Fisher Ranch WTP (TP009) consists of coagulation, flocculation, sedimentation, dual media filtration and post-chlorination.This plant is designed to meet the requirements of the
surface water treatment rules, as incorporated into Utah’s Rules in R309. These surface water treatment rules require removal and/or inactivation, expressed in terms of log10 credit,
of Cryptosporidium, Giardia lamblia, and viruses through treatment techniques.
The Surface Water Treatment Rule (SWTR) requires:
3.0-log10 removal/inactivation for Giardia lamblia, and
4.0-log10 removal/inactivation for virus.
The Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) established four bin classifications for Cryptosporidium based on concentration in the source water. If a water system
has source water classified in Bin 1, LT2ESWTR requires 2.0-log10 removal forCryptosporidium. If a water system has source water in Bin 2, Bin 3, or Bin 4, LT2ESWTR requires additional
treatment, disinfection or inactivation for Cryptosporidium, as outlined in EPA’s “Long Term 2 Enhance Surface Water Treatment Rule Toolbox Guidance Manual.”
The water source supplying this treatment plant is the Provo River Intake (WS009). The first round of sampling under LT2ESWTR began in 2020. On September 8, 2021, the Division issued
a letter classifying WS009 as a Bin 1 source based on the first round of sampling data. The Fisher Ranch WTP (TP009) is designed to meet the Bin 1 requirements, i.e., 2.0-log10 removal
for Cryptosporidium.

A second round of LT2ESWTR sampling must begin within 6 years of the initial bin classification and must be conducted on the untreated influent water after the backwash recycle stream
has been added. Following completion of the second round of LT2ESWTR source water monitoring required under R309-215-15(2)(b), filtered systems must recalculate the Cryptosporidium bin
concentration and report the bin classification to the Director for approval no later than 6 months after monitoring is completed. If the Bin classification has changed, Fisher Ranch
WTP (TP009) will be required to provide additional treatment disinfection or inactivation for Cryptosporidium.Compliance StrategyPrimary FiltrationThe dual media filters are manufactured
from AWC Solutions and consist of:36 inches of Anthracite, effective size 0.90-1.00 mm12 inches of Silica Sand, effective size 0.40-0.45 mmThe Division approves the Fisher Ranch WTP
(TP009) as a conventional filtration treatment plant under the surface water treatment rule and grants 2.5-log10 credit for Giardia lamblia removal, 2.0-log10 credit for virus inactivation
and 2.0-log10 credit for Cryptosporidium removal for the dual media compliance filter.
Per R309-200-5(a)(ii) and R309-530-9, the turbidity performance standard for this treatment plant is that the turbidity shall be less than 0.3 NTU 95% of the time, and shall not exceed
1.0 NTU.
Disinfection
A sodium hypochlorite disinfection process will be installed following the conventional filtration process to provide additional treatment to meet the Bin 1 surface water treatment goals:
Post chlorination through onsite sodium hypochlorite generation of 0.8% solution will be provided for additional inactivation through disinfection following the filtration process.
An estimated disinfection CT (CT = Concentration × Contact Time) of 61 will be achieved, which will complete the 0.5-log10Giardia and 2.0-log10 virus inactivation requirement.
The CT calculations are based on the combined CT achieved from the clearwell and transmission pipe prior to any service connections. The chlorination CT calculations were determined
based on the following information assumed to be the worst-case scenario:
Minimum free chlorine residual of 0.8 from the clearwell outlet and 0.5 from the analyzer at the end of the transmission line segment.
Peak flow of 2,800 gpm.
Minimum clearwell volume of 198,092 gallons, based on low level set point of 9.7 feet, with a baffling factor of 0.3
Minimum pipe volume of 246,729 gallons through 22,000-feet of 16-inch transmission pipe and a baffling factor of 1.
pH of 8.5.
Temperature of 3 degrees Celsius.
The Point of Entry (POE) sampling location for the Fisher Ranch WTP is the continuous analyzer located approximately 22,000 feet from the WTP on the 16-inch diameter transmission line
prior to the 600,000-gallon storage tank (ST022) and before any service connections.
Overall, the Fisher Ranch WTP (TP009) design meets the required treatment for Cryptosporidium for surface water classified as in Bin 1 under R309-215-15 of Utah’s Rules. The processes
of dual media conventional filtration and post-chlorination together will achieve the treatment goals of:
3.0-log10 removal required for Giardia lamblia,
2.0-log10 removal/inactivation required for Cryptosporidium (Bin 1 requirement), and
4.0-log10 removal/inactivation for virus.
