To date NWS has developed and implemented Water Conservation projects to numerous Federal Buildings across the United States.

 

The Challenge
Facing increasing water and sewer rates with a infrastructure that was rapidly aging, these federal facilities realized that one way to cut overhead was to reduce  the escalating costs of water and sewer. What they didn’t realize was the impact reducing water and sewer consumption would have on reducing their energy bills as well.


The In-depth Analysis
The Federal Government decided to investigate water conservation as a part of their overall energy reduction program to upgrade these six facilities. Most of the buildings were built in the 1970’s and 1980’s. Like in many Federal Facilities, maintenance and upgrades to plumbing systems have been sacrificed over the years resulting in an antiquated system that used more water and sewer than necessary.

 

National Water Services was brought in to audit these facilities and to determine the feasibility of such a project. After performing an Investment-grade audit, NWS determined that a domestic water conservation program would fit their needs to:

 

1.    Provide more efficient equipment, thereby reducing water and sewer costs.
2.    Install new equipment with an estimated life span of more than 30 years.
3.    Provide new equipment that could generate a payback that would pay for itself relatively quickly.

 

The Solution
These properties, with relatively high water and sewer rates, as well as densely occupied office areas and a significant amount of foot traffic, were ideal candidates for the installation of High Efficiency fixtures. After completing an investment grade audit, National Water Services made the following recommendations:

 

  • 404 water closets were replaced with 1.28 gallon per flush models
  • 114 urinals were replaced with One Pint Commercial Urinals
  • 428 faucets were reduced to 0.5 gallon per minute
  • 60 showers were replaced with 1.50 gallons per minute models
