Citywide Infiltration/Inflow Analysis
Change Order No. 2

To approve Change Order No. 2 for the Citywide Infiltration/Inflow Analysis to Wright-
Pierce of Manchester, NH in an amount of $23,709. Funding will be through:
Department: 169 - Wastewater; Fund: Wastewater; Activity: Inflow and Infiltration.

On February 29, 2016, this board approved the Citywide Infiltration/Inflow Analysis to
provide citywide metering of the sanitary sewer network for eight weeks during the
spring season which typically has higher groundwater and wet weather events for the
purpose of identifying extraneous infiltration and inflow (I/I) in the wastewater collection
system. Data from the flow metering will identify sewer subareas with high infiltration
and inflow and will allow the consultant to provide recommendations for further
investigations and removal of I/I.

To get enough data to analyze, rainfall in amounts of a half inch or more is needed.
During the eight week metering period which ended on May 27, 2016, only one rain
event occurred that had one half inch of rain. For this reason, Change Order No. 1 for
$9,882 was issued extending the metering period for 14 days. While one additional rain
event above one half inch has occurred, four rain events are needed for reliable results.
This request for Change Order No.2 is to extend the metering period until July 1 to
acquire the best results possible to complete the I/I analysis. The meters can be
withdrawn prior to July 1 for a cost savings if the necessary rain events occur.

The total contract value with Change Order No. 1 is $178,775. With Change Order No.
2, the total contract value is $202,484.

PAST PERFORMANCE

In March 2020, the COVID-19 pandemic was declared a major disaster throughout the United States. As a result, Saline County
received funding and anticipated the disbursement of additional funds from various federal government response and rescue acts.

Kansas Governor Laura Kelly issued an emergency declaration in the same month and authorized the use of state resources and

personnel to assist with response and recovery operations that meet certain criteria,

SITUATION

Located in the center of the state, in the center of the country, Saline County is home to
approximately 55,000 residents. The County sits 8G miles north of the state's largest city and 100
miles west of the state capital. in early 2020, the State of Kanses awarded the County over $11
million in CARES Acts Coronavirus Relief finding, which was used to distribute funding to the
County government, two cities, three school districts, K-12 schools, and numerous non-profits.

TASK

As part of the American Rescue Plan Act of 2021 (ARPA), the County anticipated receiving

an additional $10.5 million in additional funds. These funds were received directly from the US
Treasury rather than the State of Kansas, which prompted the County to seek outside support.
iParametrics was retained by the County to support the County staff's capabilities to ensure
compliance with federal regulations while maximizing the beneficial uses of ARPA dollars in the
local community.

ACTION

The iParametrics team is providing the County with technical advistory services related to
COVID-19 recovery while developing and implementing strategies designated to maximize
federal and state assistance. Additionally, we are assisting in the distribution of ARPA funding while
working with local communities and neighboring counties to ensure consistency with COVID- 19
response and recovery initiatives.

RESULT
While this project is ongoing, we are currently managing the distribution of ARPA funding to sub-
recipeints and have provided the County a technology solution for tracking this process,

Board of Public Works Meeting Date: May 26, 2016

Wastewater Collection System Operation and Maintenance — Study
Proposed draft of Scope of Work

To approve the engineering contract for the Wastewater Collection System Operation and
Maintenance - Study to CDM/Smith of Manchester, NH in an amount not to exceed
$200,000. Funding will be through: Department: 169 - Wastewater; Fund: Wastewater;
Activity: CSO Consent Decree Projects.

Discussion: The city owns and operates almost 300 miles of sanitary and combined
sewers, some dating to the 1880’s. In addition, the separated drainage collection system
consists of diverse components including 138 miles of pipe which includes drain pipes,
culverts and catch basin laterals; 40 detention ponds, over 12,200 structures consisting of
drain manholes, catch basins and headwalls. The purpose of this study is to develop a
plan that is practicable and affordable to clean, repair and maintain the wastewater and
drainage collection systems so they can provide a maximum level of service.

Tasks to be completed during this study include reviewing the existing systems and their
inspection and maintenance programs, evaluating computer software (Cartegraph) usage,
reviewing existing budgets, developing a task list for system wide operation and
maintenance (O&M) prioritization of major rehabilitation based on risk and overlays on
other roadway assets and utilization, and developing an implementation schedule with
cost estimates and budgeting options. These sewer and drain systems are quite extensive.
They need a proper maintenance program in order to function in terms of flow, capacity,
extension of material life, prevention of flooding and reduction of CSOs. A large
percentage of the very old pipes totaling about 100 miles are at the end of their useful life
and some fail abruptly causing sinkholes and require high cost emergency repairs. These
pipes need to be identified and prioritized for rehabilitation. An O&M plan for the sewer
system is also required by the EPA and NHDES for the wastewater treatment discharge
permit as well as by the CSO Consent Decree. Regarding the drainage system, the
majority of stormwater management components have fallen into disrepair, and are no
longer effective and cause problems with flooding and erosion. An O&M plan is also
necessary and will be identified as a key point of the new MS4 permit.

A Request for Qualifications was emailed to ten engineering consulting firms and posted
on the City’s website. The following three firms submitted Qualification Statements on

April 28:

Wright-Pierce of Manchester, NH
Hazen of Boston, MA
CDM/Smith of Manchester NH

Interviews with each firm were conducted on May 4. All three firms are qualified to
complete the work. However, CDM/Smith has more local experience with communities
of similar size and type. Engineering is continuing to refine the scope of work and

fee for this project so a not to exceed amount has been requested.
