Purpose
The purpose of this project is to evaluate the Scotts Creek Wastewater Treatment Plant
by performing a condition and capacity assessment, evaluating the capacity of the
existing facility to meet future demand and make recommendations for improvements to
the facility or unit processes. Scope of Services
The Scotts Creek Wastewater Treatment Plant utilizes a SBR (sequencing batch
reactors) activated sludge system for wastewater treatment. The plant's current capacity
is 2.2 MGD, although the plant is permitted for full build out, 4.5MGD. The treated effluent
is discharged into the Loosahatchie River.
The evaluation will consist of two components, a capacity assessment, and a condition
assessment.
Capacity Assessment
By 2026, the City will be redirecting wastewater flow currently flowing to the City of
Memphis Fletcher Creek Interceptor to the Scotts Creek WWTP via the new Oliver Creek
Interceptor. The current average daily flow is approximately 0.60 MGD per day. With the
additional flow it is estimated the average daily flow will increase to approximately
1.5MGD. The plant has the capacity to treat the additional dry weather flow, however
during large rain events it is expected the flow will exceed the capacity of the plant. The
capacity assessment will be used to identify and prioritize the need for expansion of the
facility or individual processes. The Consultant will provide recommendations for
managing the excess wet weather flows and options for phasing in a plant expansion.
Condition Assessment
The Scotts Creek Wastewater Treatment Plant was constructed in 2007. Most of the
equipment is original to the facility. The condition assessment will include an assessment
of each treatment process, process mechanical components, and overall performance
and operation of the system. The Consultant will provide individual inspection reports and
a summary of the data collected including condition ratings, replacement schedule,
recommendations, and budgetary cost estimates.
