Water Recycling Technology

 

1drop-2uses - Water Recycling

1 drop > 2 uses

BENEFITS FOR:

Shower water recycling for toilet flushing:

  • 5 – 10 year payback
  • Reduces potable water demand for toilet flushing by 70 – 90%

Laundry water recycling:

  • 1 – 5 year payback
  • Reduces water consumption by 80 – 90%

 

Ten to fifteen gallons per person per day is expended doing one simple task – taking a shower. Six to eight gallons per person per day is expended doing one task we all could to without – laundry! If one person showers daily for a year and does 52 loads of laundry, roughly 4,000 gallons of water will be consumed – about half the size of an average size swimming pool.

In the case of a 2,000-bed correctional facility, the water used to support showers and laundry is roughly 17.5 million gallons per year or approximately 1,750 swimming pools.

Large developments continue to work with emerging challenges in the water management field. The shortage of water and the escalating cost of water pose difficulties for industries such as hospitality, correctional, healthcare, casinos, and the like.

Valentine Environmental Engineers worked with Corrections Corporation of America (CCA) to evaluate ways to improve water usage at their facilities while simultaneously cutting long term costs. In Eloy, Arizona, CCA utilized Valentine to facilitate their Industrial Reuse Permit for over 50 grey water treatment systems at their correctional complex. In addition, Valentine analyzed CCA’s San Diego Replacement Facility for ways to reduce potable water usage and save money.

The Solution

Treating shower water for use in toilet fl ushing and laundry water recycling significantly reduces potable water use and in the long term is more cost effective for the developer. The Shower water Recycling Treatment System includes filtration, UV disinfection and effluent storage and pumping. The system will be the first of its kind at a large scale development in California.

Benefits to CCA and the community:

Shower water recycling

  • Reduce potable water consumption for toilet flushing by 88 million gallons per year
  • 9.4 year payback

Laundry water recycling

  • Reduce potable water consumption for laundry by 6 million gallons per year
  • 4.4 year payback
  • $2700 per month energy savings

Another example would be to consider a 400-room hotel that runs at 70% occupancy and washes 15 pounds of laundry per room on premise.

Using a system to recycle laundry water will on average:

  • Conserve over 6.5 million gallons of drinking water per year
  • Prevent 6.5 million gallons of chemical laden wastewater from returning to the environment

The use of water recycling technologies can assist correctional, healthcare and hospitality industries in developing a cost effective solution that is also good for the environment. Any industry with large facilities and developments can take advantage of these cutting-edge technologies and systems to be more environmentally sound and reduce cost.
