III. DESCRIPTION
A. Back rg ound
In March 2009 City Council approved task order #10006 with MSA for On-Call
Collection System Engineering Services. The services in the task order included
Page 1 of 3
a flow monitoring plan for spring rainfall events `in 2009. Data collected from
the flow monitaring can be used in ndentfying areas of infiltration and inflow
(UI} and in the calibration of a future sewer model.
B. Proposed Proect
The proposed task order #14127 with MSA will continue .flow monitoring efforts
for Fall 2049 rainfall events. The continuation of flow monitoring will identify
more areas of UI and will facilitate an accurate calibration of the future sewer
model. MSA will also make recommendations for the rehabilitation or
replacement of pipelines to help reduce the UI rates in order to stay within the
City's permitted 7 MGD limit on discharges. at the W WTP.
C. Consultant Selection
MSA has supported the City's collection system improvement efforts since 2005.
The engineers at MSA have.. extensive knowledge of flow moni oring,
infiltration inflow and rehabilitation methods, which compelled Public Works to
continue working with MSA for the UI study efforts.
iV. IMPACT
A. Strategic Impact:
This project supports the Public `Works Mission and Vision for strategic growth.
The identification of areas of infiltration .and inflow is responsive, innovative,
and opportunistic in planning for growth and- increases operational efficiencies
by establishing a plan to reduce the UI to comply with current NPDES limits of 7
MGD at the WWTP.
B. Service/Delivery Im act:
The identification of additional infiltration and inflow areas will help plan for the
rehabilitation or replacement of pipelines and manholes. which will reduce the
rate of UI in order to stay below the pernitted flow rate of 7 MGD at the WWTP
and. >allow the City of Meridian to serve more customers without exceeding
permitted flow rates.

V. .ALTERNATIVES
A. The City could .defer this flow monitoring effort and use only spring rainfall
events in the planning of system rehabilitation. and the development of the
future sewer modeh This alternative would limit the ability to identify new
areas of I/l and lessen the accuracy in the calibration of the future sewer model.
B. WWTP Staff could perform the flow .monitoring and Engineering could
analyze the data. to develop a plan to reduce UI ,and incorporate the .data into
the future sewer model and develop a .plan. to reduce UI. This alternative
would require WWTP staff to take considerable time from other scheduled
collections system maintenance such as CCTV and cleaning of pipelines.
Consultants have specific expertise in flow monitoring data analysis and have
additional resources to complete the project in a significantly shorter time
frame.
VI TIME CONSTRAINTS«
Council's approval will allow flow monitoring to occur during fall rainfall events. to
maximize the .ability to indentify areas of UI. Once the flow monitoring.... is
completed, the data collected will be used to develop a plan to reduce I/I and allow
staff to plan. for rehabilitation projects. The data collected will also be used to
calibrate a-:new sewer model under a separate contract beginning in early 2010.

CITY OF' MERIDIAN
This Scope of Services is for Professional. Services_between Murray,. Smith & Associates Inc.
{MSA) and the City of Meridian,. Idaho. Services authorized by this Task Order No.10127 shall
be for professional engineering services in support of the City's Collection System. The teens of
this Task Order shall be in accordance with the MSA Master Agreement for Professional
Services dated June 2007.

BACKGROUND
Over the past several months MSA has been evaluatinghistorcal collection system flow
monitoring data in addition to information: collected in the spring of 2009 to identify both the
magnitude and location of infiltration and inflow in the system. Additional flow monitoring in
the fall of 2009 has been completed in order to identify infiltration related impacts. This task
order will be for services provided between September l 5`h and November l `" as verbally
authorized by City staff, and estimated work through the end of 2009...
SCOPE OF SERVICES
The following: tasks are included in this scope of work::
1. Collection and Evaluation of Fa112009 Flow Monitori~ig Data
Task 1 -Collection and Evaluation of Fa112009 Flow Monitoring Data
In early September 2049 MSA, working with City O&M staff identified and installed four (4)
flaw meters for the evaluation of irrigation cana# induced infiltration. MSA will be responsible
for the maintenance and downloading of the data for those meters. MSA proposes to leave those
meters in place until it-appears that the flow has reached: a "base flow" condition when reviewing.
data from the meters and at the WWTF {through the end of the year). Previous contracts.
provide for adequate budget to maintain the meters through mid September.. This task provides
for additional budget to maintain and download the meters through the falt of 20t1y and for the
evaluation of the data.
Assumptions: City staff will remove the flow meters in ate December as requested by MSA.
Eight (8) hours of time has been-.assumed for sixteen: weeks duration .for one staff for the
maintenance and downloading of the data. This scope assumes City staff are only available to
assist MSA under emergency conditions, such as the failure of equipment, MSA will utilize a
.subcontractor as needed for confined space entryrequirements for the regular maintenance-and
downloading of the meters: This scope and budget includes up to $3,000 for the use afthe-
confined space entry subconsultant.
Deliverables:. Technical memorandum documenting the four {4) infiltration focused flow meter
locations collected in the fall of 2009 and recommendations for 2010 infiltration monitoring and

potentially the recommendation for the rehabi taton or replacement of pipelines in the
monitored area. A CD containing;all collected flflw monitoring data will be provided to the City
at the conclusion. of the project.
BUDGET
The overall Not-taExceed Budget for this scope of work is $23,5'52.. The work will be billed on
a time. and expenses basis. MSA staff billing rates w l be adjusted annually. The total budget for
this Task. Order shall not be exceeded without written. authorization.
if additional tasks are requested. beyond the initial budget allocation, MSA will provide atask-
specific scope and budget for each. support request from the City. The. City will provide email or
hardcopy authorization to MSA to proceed based on the scope and budget provided.
Assumptions, deliverables, schedules, and data requests will he outlined in each task specific
scope.
