TASK ORDER 14
THIS TASK ORDER IS PURSUANT TO THE AGREEMENT FOR CONSULTING ENGINEERING SERVICES BETWEEN
CLAY COUNTY UTILITY AUTHORITY AND CONSTANTINE ENGINEERING,LLC.,(RFQ No.18/19).WHICH IS
INCORPORATED HEREIN BY THIS REFERENCE,WITH RESPECT TO
Scope of Services
for Professional Engineering Services for Miller Street
Wastewater Treatment Evaluation and Improvements Project
Article A. Purpose:
The purpose of this Exhibit is to authorize and direct the Constantine Group, LLC
(CONSULTANT) to provide Project Management and Conceptual Phase services for the Miller
Street Wastewater Treatment Facility (MS WWTF) Evaluation and Improvements for the Clay
County Utility Authority(OWNER).
CCUA operates and maintains the existing MS WWTF that serves the area in the vicinity of the
Orange Park service area. The existing facility consists of a headworks,two (2) oxidation ditches
with brush aerators, four (4) final clarifiers, two (2) traveling bridge sand filters, and chlorine
contact chambers for disinfection. Effluent is discharged to public access reuse or the St. Johns
River. The facility was constructed in the early 1970s and most of the structures and equipment
are in need of improvement. Immediate improvements are required at Headworks where
significant deterioration of the concrete, mechanical and electrical equipment was observed
during site visits to the facility. During the site visits, it was decided the Headworks was to be
replaced with a new Headworks meeting current CCUA standards. Additional immediate
improvements include replacement of the electrical equipment throughout the site and
addressing safety concerns. This project includes a conceptual evaluation to replace the existing
Headworks and electrical equipment at the MS WWTF.
The MS WWTF has a permitted capacity of 4.95 mgd annual average daily flow(AADF). Influent
flows to the facility over the last several years range between 1.0 to 1.3 mgd AADF. This has
resulted in several unit processes to remain out of service. CCUA's Orange Park service area is
built out and no additional flows are anticipated to be sent to the MS WWTF.This project includes
a master plan for the MS WWTF that will identify the long-term capacity and treatment needs for
the MS WWTF including unit process evaluations for optimal treatment to meet future
regulations (5 mg/1 TSS, 5 mg/1 BOD, 3 mg/1 TN, 1 mg/1 TP), and effluent management
strategies taking into account the impacts of Senate Bill 64.
All services will be provided as described in the scope of services below.

Task 3 - MS WWTF Master Plan
The MS WWTF Master Plan will include an evaluation for long-term capacity and treatment
needs based on economic, regulatory and operation and maintenance requirements. The Master
Plan will include:
3.1: Wastewater Flow and Load Projections
Wastewater flow and loadings will be provided by CCUA. The information will be evaluated to
determine future capacity needs for the facility. This includes derating the facility if population
growth in the Orange Park service area has reached buildout conditions. CONSULTANT will
utilize the data provided by CCUA and other industry approved methods to make
recommendations on WWTF permitted capacity and peaking factors.
Based on data from the existing MS WWTF and recent typical wastewater characteristics in
CCUA's service territories,wastewater loadings will be developed for use as the basis for process
evaluation of the facility. CBOD, TSS, total Kjeldahl nitrogen (TKN), total Nitrogen (TN),
ammonia (NH3N), and total phosphorus (TP) will be the primary wastewater constituents of
concern.The data will be analyzed for potential infiltration and inflow(I&I)issues that may exist
at the facility. This task will include one (1) site visit to inspect areas of the collection system
where I&I may exist.
The analysis will be performed with the goal of producing effluent standards below the
requirements associated with disposal to public access reuse (PAR) and advanced water
treatment standards (5/5/3/1).
A draft TM will be prepared summarizing the evaluations,findings, and recommendations.
3.2: Process Evaluation
CONSULTANT will perform a process evaluation of the MS WWTF to evaluate the existing
facility operation and the most effective and economical long-term treatment options. The facility
is currently operating well below its permitted capacity and as a result several unit processes are
not in use. Unused structures will be evaluated for salvaging and repurposing for alternate use.
Each unit process will be evaluated to optimize treatment, and improvements recommended
based on economic,regulatory, and operation and maintenance parameters.
A draft TM will be prepared summarizing the evaluations,findings, and recommendations.
3.3: Effluent Management
The current approach for effluent management is to discharge to PAR. Effluent during wet
weather periods is sent to the St.Johns River. The MS WWTF also receives effluent flow from the
Orange Park WWTF. Effluent received from the Orange Park WWTF is introduced upstream of
the MS WWTF chlorine contact chambers.

TASK ORDER-CLAY COUNTY UTILITY AUTHORITY
MILLER STREET WASTEWATER TREATMENT FACILITY EVALUATION AND IMPROVEMENTS PROJECT
The evaluation will include reclaimed water storage considerations so that the facility can treat
and manage future flows with PAR. CONSULTANT will evaluate the impact of Senate Bill 64 on
the facility and identify additional effluent management options to evaluate with the OWNER
including utilizing existing tankage for wet weather and reject storage.
A draft TM will be prepared summarizing the evaluations,findings, and recommendations.
3.4: Conceptual Document
After the completion of Tasks 3.1 through 3.3, CONSULTANT will hold a workshop with the
OWNER to discuss the alternative evaluations and recommendations presented in each TM. The
