Project Description:

The Little Falls Run project is the first phase of the Wastewater Treatment Plant's upgrade process. The project's objective is to enhance the efficiency of the nutrient removal system by installing new blowers and air piping. American Contracting is currently on site and working on the following elements for the job:
  • Four new precast post-tensioned concrete Sludge Storage Silos
  • Two new UV Channels
  • UV Instrumentation and equipment
  • New air blowers
  • Over 2,000 linear feet of ductile iron air piping
  • Demolition and installation of new bar screening equipment
  • Aeration diffusers in the existing Sludge Storage Silos
  • New 2,500 Kw generator
  • New 8,000 gallon fuel tank

The installation of new UV channels not only gives the Plant backup, in case one set of UV instrumentation is disabled, but allows for increased outflow once the Phase II upgrade is completed in the future.
