Little Falls Run Nutrient Removal Upgrades - Phase 1
Basic Information
Owner: Stafford County, Virginia
Engineer: Parsons Engineering
Approximate Contract Value: $7,500,000
Completion Date: July 2010
Project Type: Wastewater Treatment Plant Upgrade
Project Description
This 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.
Project highlights include:
Four new precast post-tensioned concrete sludge storage silos
Two new UV channels with UV instrumentation and equipment
New air blowers and 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 and new 8,000 fuel tank
The installation of new UV channels not only gives the plant backup in case one set of UV instrumentation
is disabled, but it allows for increased outflow once the phase II upgrade is completed in the future.
