Capital Projects

Posted on: February 28, 2012

AWA is never without an ongoing project or two or three. For example, here are some of the ways the system has been improved over the last few years:

  1. Water Purification Plant
    • Two years ago the plant roof was replaced with a steel standing-seam type of roof.  You can see it very clearly from the northern-most Ambridge traffic light on SR65.  Very handsome, this type of roof can last 100 years with little maintenance.
    • The mixing chambers at the plant were renovated with new mixers, floor supports, ladders and grating.  The mixing chambers provide the necessary process by which a flocculant is introduced into the raw water in order to capture minute organic material into a form that can be removed.
    • Presently the sedimentation basins are being internally rebuilt, with old unused equipment removed, concrete repair, and the installation of a tube settler system.  Track-driven vacuuming devices were previously installed as the first part of this project.  These basins provide the first opportunity for floc (organic debris) to settle out of the water, before the water is further processed by filtration.
  2. New Water Tank for Economy Boro
    • Due to the growth of Economy Boro, additional water storage was needed.  With assistance from Traditions of America (Liberty Hills Development), AWA was able to build an additional half-million gallon tank reservoir on Conway-Wallrose Road.  The three tanks in this location serve only the Economy area.  This is the 12th finished water storage tank within the system.
  3. Service Creek Reservoir
    • The water intake at the reservoir is an engineering marvel first built in the 1950’s.  After years of use, it was determined that extensive renovations were required.  The working parts were rebuilt and an additional gate installed on the box culvert through the dam.  All of the water our customers receive first enters the system through one of the four chambers in this structure.
    • Five large pumps in the main pumping station have been maintained and periodically replaced over the almost 60 years they have been running day and night.  However, it became necessary to upgrade the electrical system, increase the pumping capacity, and update the control systems.  This was a very interesting project and everyone involved came to admire the foresight and sound engineering of the original design, which was created without computer assistance.
