INTRODUCTION
The enclosed resolution is in reference to the public hearing for the Kerper Blvd. Sanitary
Sewer Reconstruction.
BACKGROUND
The City experienced a significant sanitary sewer overflow in August 2015 in a heavy
industrial area along Kerper Boulevard. The overflow prompted an extensive investigation
as to how and why the overflow occurred. The investigation by City staff found the overflow
had occurred due to premature weakening of the sanitary sewer. The failed section of
sanitary sewer was located through a 66-inch diameter storm sewer which allowed
wastewater to enter the storm sewer. An emergency repair was conducted; along with
heavy cleaning of the sanitary sewer. During heavy cleaning operation of the Kerper
Boulevard and the East 16t" Street sanitary sewers, significant offset pipe joints and
additional corroded pipe sectian were discoversd. During the pipe cleaning aperations, the
cleaning equipment was lodged in the ductile iron pipe. A second emergency excavation
was conducted to retrieve the equipment. Due to the condition of the existing ductile iron
pipe only a temporary repair could be made. A permanent repair was not feasible as pipe
corrosion presented difficulties in securing the repair couplings. Since there are so m�ny
locations where corrosion has affected the pipe, along this section of Kerper Blvd., it is being
recommended that full replacement and relocation of the sanitary sewer be made.
While sections of the collection system along Kerper Boulevard are in fair to good condition,
approximately 2,400 feet of 18-inch diameter ductile iron sanitary sewer is at risk between
Fengler Street and East 16t" Street. Additionally, approximately 1,800 feet of 18-inch
diameter vitrified clay sanitary sewer along East 16'" Street is distressed and in need of
replacement to eliminate I&I issues due to settlements. Additionally, the 18-inch vitrified clay
pipe is under sized to serve the current level of development. The 18-inch ductile iron pipe,
along Kerper Boulevard, was installed in 1994 and the 18-inch vitrified clay pipe, along East
16t" Street, was installed in 1957.

several attempts to clean, televise, and repair the sewer it was discovered that the pipe wall
thickness is severely compromised. Further, the existing manholes show signs of sulfuric
acid attack and the section of pipe removed during the repair made in August of 2015
showed signs of extensive corrosion. Many reasons are known as to how hydrogen sulfide
can develop in a system such as low pH in the wastewater and reduced velocity or
increased retention time of wastewater in the collection system.
Engineering staff have identified several different issues with the Kerper Blvd. sanitary
sewer and investigated different options for the replacement of the sewer. Staff selected
one of the options and issued the design for bidding in May of 2017. The estimated
construction cost of the project was $3,762,675.00. Two Bids were received on June 8,
2017, for the Kerper Blvd, Sanitary Sewer Reconstruction project. The bids were
substantially over the estimated construction cost with a low bid of$5,494,539.26, both bids
were rejected.
DISCUSSION
Engineering staff re-evaluated the design for cost saving measures and developed three
additional design alternatives for consideration. The selected alternative is for full
replacement of the failed gravity sewer system, on Kerper Boulevard, with a combination of
a force main and gravity system. The new alignment will start at an existing manhole,
connected to a 24-inch diameter sanitary sewer with sufficient capacity to accept flows from
the Kerper Boulevard service area. Approximately 2/3 of the project will be able to be
constructed within public right-of-way, the remaining 1/3 will be constructed on easements
across private property.
The selected alternative reduces estimated construction costs and impact to businesses and
traffic along E. 16th Street, near Kerper Blvd. This was achieved by modifying the previous
alignment and utilizing a single lift station and force main. The modified alignment is located
along the U.S. Highway 151/61 corridor, between E. 16th Street and Kerper Blvd. The single
lift station allows for a much shallower pipe installation and avoids the need for dewatering
and specialized trench shoring for that portion of the project. This alignment modification
also eliminated the majority of pavement replacement costs on E. 16t" Street and at the
intersection with Kerper Blvd. This change in alignment also avoids the need to close the
U.S. Highway 151/61 ramps, at Kerper Blvd., and virtually eliminates the access impact to
businesses along E. 16th Street.
Additionally, the new project scope eliminates the costs associated with the replacement of
the 1950's era sanitary sewer along East 16t" Street. Currently the existing sewer is
undersized for the area that it serves. The modified alignment eliminates the Kerper Blvd.
sanitary sewer flow from entering the existing undersized sanitary sewer on E. 16t'' Street.
The elimination of the Kerper sanitary sewer flow, from the E. 16th Street sanitary sewer,
also has the potential to reduce future sewer replacement costs. The existing sewer, on E.
16th Street, could be replaced with a smaller diameter pipe and at a reduced depth.
2
In late July, Engineering staff revised the previously submitted and approved facility plan to
reflect the revised concept. The estimated cost of$3,774,954.70, for the revised concept,
was also included as part of the amended facility plan. The lowa Department of Natural
Resources (IDNR) have reviewed and approved the amended facility plan so that the City
can apply for a SRF loan to cover construction and contingency cost. The Engineering and
design costs will be paid by the sanitary construction fund.
The final design was completed the week of October 1 St, along with a construction cost
estimate based on the completed design. The final construction cost estimate including, a
contingency of$389,415.00 is $4,283,567.31, which is $508,612.61 more than what was
submitted with the facility plan, in July, and $1,083,567.00 more than the previously
approved Intended Use Flan (IUF).
The plans, specifications, revised estimate and an amended IUP application were
submitted, to IDNR, for approval and construction permitting on October 4.
PROJECT SCHEDULE
The schedule for the project is as follows:

project that would allow the project to be within the budgeted amount. The identified items
would reduce future maintenance and cleaning costs of the Fengler Street lift station. The
estimated reduction in construction costs, of not including these items, is estimated to be
approximately $342,675.00.
