SCOPE OF SERVICES
INTRODUCTION
The purposes of this Task Order are:
(1) to assist the City with designing, procuring materials for, and implementing modifications
to the existing nitrogen removal basins at the WWTP in accordance with recommendations
of the June, 1999 Nitrogen Removal and Permit Compliance report prepared under Task
Order 1 (Amendment 1) of the Agreement.
(2) to further develop and expand the study evaluating potential for and extent of nitrogen
removal in the natural systems in and underlying the City's effluent disposal ponds as
originally authorized by Task Order 2 (Amendment 2) of the Agreement. This work will be
performed by a team of Carollo Engineers and Wildermuth Environmental.
SCOPE OF SERVICES
To provide the needed assistance and perform the required evaluations, the following tasks will
be necessary:
Task 1 Assist with modification to the existing nitrogen removal basins
1.1 Analyze the flow rates, hydraulics and piping and pumping systems to determine sizes and
characteristics required.
1.2 Provide technical specifications for the mechanical equipment ( recirculation pumps and
mixers) so that the City may purchase the equipment.
1.3 Design equipment and piping supports and other appurtenances necessary for
installation. Design of electrical systems to power, control, and operate the equipment will be
designed by the City and is not a part of this scope of services.
Task 2 Study of nitrogen removal in the effluent disposal ponds
To assist the City in completing the study, developing protocol and methodology, providing
assistance and advice during the study, interpreting the results, documenting the work, and
obtaining regulatory acceptance, as outlined in the following tasks, Will be necessary. The study
covered by this scope is meant to evaluate removal of nitrogen in the soil column under and
immediately adjacent to the existing ponds and to determine a fill and drain cycle and other
operating criteria consistent with good nitrogen removal. At the option of the City, the scope can
be expanded to evaluate other topics such as removal mechanisms, removal of other
constituents, area hydrology and other subjects, the need for which may arise during the study.
2.1 Meet with the City to discuss the project and collect available information.
12/13/2000
H:\Client\Redlands-SAOW,ContractNitTO4.doc A-1
2.2 Develop a tentative protocol for the study and meet with the RWQCB to discuss and
finalize it. The protocol will include locations and types of monitoring and sampling
systems, sampling schedules, analytical methods, report format and content, and timing. It
should be recognized that the need to modify parts the protocol should be expected as
the study progresses.
2.3 Assist the City by recommending the selection, location, design, installation, and operation
of sampling and monitoring systems.
2.4 Provide a monthly overview of operation and findings from the project. Meet with the City
to discuss the findings and any apparent need to modify the protocol.
2.5 Prepare monthly reports summarizing the findings for the period for the City to file with the
RWQCB.
2.6 Prepare a draft and final report summarizing the work, giving and interpreting findings, and
recommending criteria for operating the ponds as a nitrogen removal process.
2.7 After filing the draft report, meet with the City and the RWQCB, if required,to discuss
modifications to the City's waste discharge requirements and any benefits of continuing
the monitoring program.
Services Provided by City
The City will provide the following:
1. All construction including that of monitoring wells, sampling stations, lysimeters, and
access roads.
2. Geotechnical investigations, if they become necessary, including hydrogeological studies.
3. Sampling and laboratory analyzes of samples.
4. Operation of treatment, pumping, water transmission and flow control systems and the
ponds.
5. Information from any previous studies regarding hydrology, monitoring programs, well
logs, groundwater quality and depth, and pond operation.
