Re: Proposal of Engineering Services
Flow Metering and Infiltration and Inflow (I/I) Study
Dear Mr. Vogras:
As you are aware, the Oakland County Evergreen-Farmington Sewage Disposal
System has experienced high flows and bypasses due to the presence of excessive
inflow and infiltration (I/I). Recent studies performed by the Oakland County Drain
Commissioner's (OCDC) office have suggested that the sources of the excessive I/I are
contained within the communities that discharge to the interceptor system, including
West Bloomfield Township. In order to verify the conclusion of the OCDC, and
determine the locations and sources of any I/I within the Township's sanitary
collection system, we have prepared this proposal for performing a flow metering and
infiltration and inflow (I/I) study of the Township's sanitary collection system.
The study will investigate whether the observed surcharging and bypassing M the
County system is caused by sources of I/I within the Township's system or is caused
by the downstream interceptor system operated by the OCDC. If excessive I/I is found
in the upstream system, the study will also determine the locations and sources of any
excessive I/I within the Township's system, and include a preliminary cost
effectiveness evaluation of I/I source removal versus constructing sanitary storage
facilities.
At your request, we have reviewed the Township's sanitary collection system and the
permanent flow metering system operated by the OCDC. The OCDC currently
maintains nineteen (19) permanent flow meters within West Bloomfield Township
which are capable of splitting the Township into approximately 12 sub-areas.
Therefore, we have concluded that initial temporary flow metering in the Township is
not necessary. In order to perform the study, data will be collected from the OCDC
meters for the period of March 1, 2000 through May 31, 2001. We have contacted the
OCDC and verified that the data is available and can be used for the study.

We have prepared the attached work plan to prepare the flow monitoring and I/I
study. In order to efficiently complete the study, we have divided the project into two
(2) phases. The first phase of the project will involve collecting flow data from six (6)
flow meters operated by the OCDC that are downstream of the Township in order to
complete a simplified I/I analysis. This simplified I/I analysis will be focused on
determining whether the observed surcharging and bypasses are caused by
downstream conditions in the County interceptor system or from excessive VI
upstream in the local system(s). If the simplified I/I analysis shows that there is
excessive UI from the upstream system, then the second phase of the study will be
performed. The second phase of the project will involve collecting flow data from an
additional thirteen (13) flow meters operated by the OCDC in order to complete a
detailed I/I analysis of the Township system. The detailed I/I analysis will determine
the locations and sources of the excessive I/I within the 12 sub-areas of the Township
and include utilizing simplified techniques to verify the sizing of require sanitary
retention facilities.
We propose to perform the first phase of the study for a not-to-exceed fee of $20,000.
We anticipate that the first phase can be completed within 6 to 8 weeks after
authorization to proceed and receipt of the data from the OCDC. We propose to
perform the second phase of the study for a not-to-exceed fee of $35,000. We anticipate
that the second phase can be completed within 8 to 10 weeks after the completion of
the first phase.
We would like to thank you for the opportunity to prepare this proposal for this
interesting and important project. Please feel free to contact us if you have any
questions or need any additional information.
Very truly yours,

Charter Township of West Bloomfield
Flow Monitoring and Inflow / Infiltration Study Work Plan
April 2001
BACKGROUND
Historically, the Evergreen-Farmington Sewage Disposal System has experienced high flows and
bypasses due to the presence of excessive inflow and infiltration (I/I). Recent studies performed
by the Oakland County Drain Commissioner (OCDC) have suggested that the sources of the
excessive L'I are contained within the communities that discharge to the interceptor system.
However, a review of the sanitary bypasses in the vicinity of West Bloomfield Township shows
that the bypasses are caused by the throttling of the Walnut Lake Pump Station #1 by the OCDC.
Therefore, it is unclear whether these bypasses are caused by excessive I/I in the Township's
sanitary collection system or caused by surcharging in the downstream OCDC interceptor
system.
In order to investigate whether the Township's sanitary collection system contains excessive I/I,
the Township has asked Ayres, Lewis, Norris & May, Inc. (ALN-M) to prepare a proposal for a
flow monitoring and I/I study. The project will focus on the portion of the Township tributary to
the Evergreen-Farmington Sewage Disposal System. The purpose of the study is to determine
the quantity and sources of I/I entering the sanitary collection system and to provide an
understanding of the current status of the system. The study will also be used to determine the
impact that downstream surcharging in the County system may have on the Township's sanitary
collection system. The results of the study will aid the Township in evaluating the cost
effectiveness of removinv. II and verify the basis of design for a potential future sanitary
equalization basin.
The flow chart attached to this work plan presents a typical project flow chart for improving a
sanitary collection system and reducing sanitary sewer overflows to meet regulatory
requirements. As the flow chart shows. the initial steps of the collection system investigation are
flow monitoring and FI analysis. The Ill analysis can be used to determine if it may be cost
effective to remove sources of Iil or construct large capital improvements such as a retention
basin to deal with the I/I. As the flow chart shows, if the 11 analysis shows that removing
may be cost effective, it could be necessary to perform sewer rehabilitation. Therefore, this work
plan includes performing flow monitoring and an 1/I analysis to perform a preliminary cost
effectiveness evaluation of removing 11 versus constructing a sanitary retention basin.
Developing a calibrated model of the system and a basis of design for the proposed
improvements are not included in this work plan since regional studies prepared by the OCDC
have already performed detailed modeling of the Evergreen-Farmington Sewage Disposal
System. However, simplified techniques will be used to verify the preliminary sizing for
required collection system iniprovements performed as part of previous studies by others.
DISCUSSION OF FLOW METERING
We have reviewed the Townships sanitary collection system and the permanent, regional flow
meters operated by the OCDC. The OCDC flow metering system contains approximately 19
meters within West Bloomfield Township. These meters are capable of differentiating the flow
from West Bloomfield Township versus Orchard Lake and Bloomfield Township. In addition,
these meters are capable of splitting West Bloomfield Township into approximately 12 sub-
areas. Therefore, based on the review of the OCDC metering system, we have concluded that
temporary flow metering performed by the Township is not necessary.
OVERVIEW OF PROJECT APPROACH
In order to efficiently complete the II analysis, we have divided the project into two (2) phases.
The first phase of the project will involve collecting flow data from the six (6) downstream flow
meters operated by the OCDC in order to complete a simplified Ill analysis. This simplified 1/I
analysis will be focused on determining whether the observed surcharging and bypasses are
caused by downstream conditions in the County interceptor system or from excessive I/I
upstream in the local systems. Since the flow data will be collected from the six downstream
flow meters, it will not be possible to isolate the sources of observed II or differentiate the flow
from West Bloomfield Township versus Orchard Lake and Bloomfield Township. If the
simplified the I/I analysis shows that there is excessive I/1 from the upstream system, then the
second phase of the study will be perfoiined.
The second phase of the project will involve collecting flow data from an additional thirteen (13)
flow meters operated by the OCDC in order to complete a detailed I/I analysis. This detailed UI
analysis will isolate the flows from West Bloomfield Township and Orchard Lake and
Bloomfield Township. The total of 19 flow meters examined will result in splitting the West
Bloomfield Township sanitary collection system into approximately 12 sub-areas for detailed 111
analysis. The detailed I/I analysis will determine the locations and sources of the excessive
within the 12 sub-areas. Furthermore, the detailed PI analysis will include utilizing simplified
techniques to verify the sizing of require sanitary retention facilities.
PHASE I - COLLECT DOWNSTREAM OCDC DATA AND PERFORM SIMPLIFIED I/I
ANALYSIS
1. Obtain Flow Monitoring Data
Under this task, ALNM will review and process the flow data collected from the OCDC. This
will include data from six (6) permanent flow meters and three (3) permanent rain gauges. The
data will be collected for a fifteen (15) month period from March 1, 2000, through May 31, 2001.
The data will be processed, quality checked, graphed and summarized. Specific work items of
this task include:
Obtain, review and process flow data from the 6 permanent OCDC flow meters and 3
permanent OCDC rain gauges.
Perform data processing and quality assurance / quality check of all data received.
Prepare the data in a format for incorporation into a final report that summarizes the flow
monitoring results and provides graphs and electronic copies of the processed data.
2. Perform Simplified I/I Analysis
The I/I analysis will be prepared utilizing the data collected from the OCDC. The I/I analysis
will be performed for the area tributary to the Evergreen-Farmington Sewage Disposal System.
Specific work items of this task include:
• Prepare the data processed during the flow monitoring study for the I/I analysis.
Review the findings of the OCDC's Evergreen-Fannington Sewage Disposal System
Phase I Study dated March 1999.
Review the flow data to determine the cause of surcharges and overflows. This analysis
will determine whether bypasses are caused by excessive I/I in the Township's sanitary
collection system or caused by surcharging in the downstream OCDC interceptor system.
PHASE II- COLLECT ALL OCDC DATA AND PERFORM DETAILED I/I ANALYSIS
This phase of the project will involve collecting flow data from an additional thirteen (13) flow
meters operated by the OCDC in order to complete a detailed 11 analysis. The detailed LT
analysis will determine the locations and sources of the excessive within approximately 12
sub-areas. Furthermore, the detailed IT analysis will include utilizing simplified techniques to
verify the sizing of require sanitary retention facilities.
1. Obtain Flow Monitoring Data
Under this task. ALNIM will review and process the additional flow data collected from the
OCDC. This will include data from thirteen (13) additional permanent flow meters. This will
result in the collection of data from nineteen (19) total flow meters, including the data collected
during Phase I. The data from the nineteen flow meters will result in isolating the flows from the
Township and Orchard Lake and Bloomfield Township, as well as split the Township into
approximately twelve (12) sub-areas. The data will be collected for a fifteen (15) month period
from March 1, 2000, through May 30, 2001. The data will be processed, quality checked,
graphed and summarized. Specific work items of this task include:
• Obtain, review and process flow data from the 6 permanent OCDC flow meters and 3
permanent OCDC rain gauges.
• Perform data processing and quality assurance quality check of all data received.
• Prepare the data in a format for incorporation into a final report that summarizes the flow
monitoring results and provides graphs and electronic copies of the processed data.
2. Perform Detailed I/I Analysis
The Id analysis will be prepared utilizing the data collected from the OCDC. The VI analysis
will be performed for the area tributary to the Evergreen-Farmington Sewage Disposal System.
Specific work items of this task include:
Prepare the data processed during the flow monitoring study for the analysis.
Verify the land area, house count and population of each sub-area.
Develop Thiessen polygons for the rain gages to be used in analyzing the rainfall data.
Develop capture coefficients for each sub-area for large storms. The capture coefficient
is the fraction of precipitation entering the sanitary system and can be useful in evaluating
