PROJECT BACKGROUND
One of the main components of a water utility is an adequate source water supply. In the last 10 years, five new wells have been constructed to supplement the 17 existing wells. A key element of the source water supply is conveyance capacity: that is, the ability to move water through pipes from the supply wells to the treatment facility.
Without adequate water conveyance capability, the benefits of construction new wells will not be fully realized. Restrictions in the well piping system currently prevent wells from operating at full capacity and increase energy costs. An existing pipeline is now undersized and will become even more so as new wells are constructed. This well line project will eliminate some of these restrictions and provide well line capacity for future well construction. In addition, it will provide increased reliability in the event of planned or emergency repairs for 65% of the total water supply.
SCOPE OF WORK
Install approximately 13,500 feet of 30-inch water main. The project begins at the Youth Sports Complex and crosses the Skunk River to the east. From there, the pipe will run north beyond East Lincoln Way before it crosses back under the Skunk River and then north under the Union Pacific Railroad. The pipe will then go west to the intersection of East 6th Street and Crawford Avenue. There, the new pipe will connect to an existing pipe on its way to the Water Plant.

EAST 6TH STREET CONSTRUCTION
Staff worked diligently with FOX Engineering, Inc. to develop a detailed set of plans and specifications. There are two ways to install the 30 inch pipeline on 6th Street. One way is to use a trench (open cut) and the second is to directional drill, or bore the pipeline. Trenching will close the south half of 6th Street from Crawford Street to the east end. This allows for construction equipment to dig a large trench and place the 30 inch pipeline in the ground. Some challenges residents may have with trenching are access to their driveways, yard repair, tree damage, mail delivery, garbage pickup, noise, utility shutoffs and construction site safety for children.
City staff has implemented measures in the specifications to address the concerns raised by area residents such as the following:
Objectionable noises shall not take place from 7 PM to 7 AM Monday through Friday. Weekend work is still being considered in order to complete work as quickly as possible.
The use of incentives for completing the work early and penalties for work beyond a designated deadline to expedite progress of work will be in place.
Specific instructions will be given to the contractor about construction site safety and precautions for children playing in the surrounding area.
If driveway access will be interrupted for more than one night, the contractor is responsible for making provisions for mail and garbage service.
All disturbed areas within the right of way will be replaced with sod.
