split between two trains. Train 1-Rapid Mix, flocculation and sedimentation; Train 2 Rapid Mix and Super Pulsator
to
upflow clarification. The flow from the two trains combines; followed by ozonation for primary disinfection,
in
filtration, and monochloramine for secondary disinfection. The wastewater from this process consists of alum sludge
°a
from sedimentation and Super Pulsator, filter backwash dechlorinated, continuous online analyzer discharge,
0
continuous sample tap discharge and storm water. Treatment in the residual lagoon consists of settling from the
inlet to the discharge consisting of approximately 2500 ft. over a surface area of 23 acres. Chemicals used in the

treatment process are aluminum sulfate, sodium hydroxide, powder activated carbon as needed, sodium
hypochlorite, polymer, ozone, liquid ammonia sulfate, hydrofluosilicic acid, sodium permanganate as needed,

Greenville Utilities Commission WTP Residuals Handling Plan
Greenville Utilities Commission (GUC) existing residuals comprise of sedimentation
basin blowdown, filter backwash, and filter to waste. The residuals waste streams are all
directed to a manhole. Stormwater is also conveyed to this manhole. A 30-inch manhole
with reinforced concrete pipe runs west from the manhole into another manhole where
additional stormwater is tied in. A 36-inch reinforced concrete pipe runs west from this
manhole into an outfall at the residual lagoon. During a 10-year storm an estimated
7,400 gpm of stormwater is diverted to this pipeline, which is approximately half the
flowrate of the maximum instantaneous residual stream. The residuals lagoon is
approximately 23 acres with a depth of 14 feet from the lagoon invert to grade. With an
operating depth of 11 ft., the lagoon has a corresponding volume capacity of
approximately 350,000 cubic yards at 2.25:1 slope
GUC contracted with Hazen to conduct Preliminary Engineering Report (PER) in 2017.
The final report was produced in May 2018. The PER estimates that the lagoon has
210,000 cubic yards of solids or 60 percent full. Existing residuals management
practices, solid production estimates and evaluation of future residual management
alternatives were also included in the PER. The four residual management alternatives
were:
1. Alternative 1-Use existing lagoon -continue to direct all residuals streams to the
existing lagoon.
2. Alternative 2- Construct a new lagoon -direct all residuals streams to a new
lagoon.
3. Alternative 3- Solids Thickening and Dewatering- Direct sedimentation and future
blowdown to thickening and dewatering and continue to direct filter backwash
and filter to waste to the existing lagoon.
4. Alternative 4-Solids Thickening and Dewatering and Backwash Clarification- -
Direct sedimentation and future blowdown to thickening and dewatering and
clarification for filter backwash and filter to waste.

The PER recommended that GUC select Alternate 1-continue to send all residuals
stream to existing lagoon. Also, a recommendation that GUC staff dredge new solids
that are collected to maintain the current lagoon functionality and capacity. GUC had
previously established a residual lagoon improvement capital project prior to the PER.
In December 2018, GUC proceeded with a request for bids for sludge removal from the
residual lagoon. A contract was awarded January 31, 2019 for removal of approximately
two times the annual average sludge production. GUC long term plan is to remove twice
the annual average solid production annually to restore additional capacity in the current
lagoon and future WTP expansion. The third round of dredging is set to begin April
2024 and additional funds have been allocated for future dredging projects.
