Illinois American Water Company employed Maurer-Stutz, Inc. to design a 16” transmission main in Pekin, Illinois from Sheridan Road at Rt. 29, along Sheridan Road, Sommerset, and Capitol to a connection point on Court St. The project required a deep bore and jack installation at the Rt. 29 crossing.

The completed project included 6700’ of 16” ductile iron pipe. Maurer-Stutz prepared construction drawings, completed permit applications, and provided construction observation services.

The Village of Peoria Heights pumped their finished water from a low service booster station with 3-200 Hp pumps through a 16” cast iron transmission main to a ground storage tank.  From there the water was re-pumped by 3-150 Hp pumps to their elevated storage tanks.  Due to age, the transmission main was subject to breaking, the ground storage tank was in need of significant repairs, and re-pumping the finished water was creating excessive electric costs.

The project involved the installation of 4500’ of 16” and 20” transmission main to replace the existing cast iron main, replacement of two low service booster pumps with 2-250 hp pumps, and total elimination of the ground storage tank and the high level booster pumps.   Approximately 300’ of 20” transmission main was installed up a steep wooded slope by directional drilling procedures.

The project was funded by a low interest IEPA loan.  The Village also received an energy grant for reducing the annual electric cost of their system.

Maurer-Stutz, Inc.  was retained by the City to provide conceptual planning, topographic survey, engineering design, permitting assistance, permanent easement preparation, easement negotiation assistance, bidding phase and construction phase services for the installation of a nine mile raw water transmission main from a newly constructed radial collector well to the City’s water treatment facility as an alternative raw water source to supplement the City’s current source of water provided by Canton Lake. 

Design included using 24" ductile iron pipe that was restrained in many locations due to the size of the water main, rugged terrain, expected operating pressures and peak demand velocities.   Air release, air vacuum and combination air valves were designed for this project.  Four bore and jack locations were constructed for crossings at State Routes, Railroads and County Highways. 

As a result of the reconstruction of Illinois Route 8 in East Peoria by the Illinois Department of Transportation, the North Tazewell Public Water District was required to relocate its existing water main, which lay parallel to the existing highway and in conflict with the proposed construction.

The project involved installation of 5,300’ of 8” and 10” ductile iron water main in easements outside the new highway right-of-way.  Four sections of water main had to be bored under Illinois Route 8 in order to connect the existing distribution system to the new main.  Numerous residential and commercial water services also required connection to the new main.
