Water Conservation

The Office of Sustainability and Facilities Management are working together to increase water efficiency by installing low-flow bathroom fixtures across campus.

Water-Saving Faucets and Shower Heads

All bathrooms in the North Campus Apartments, Stratton House, Slade Hall,  Miller Hall, Kresge Hall and Boylston Halls are equipped with water-saving, low flow faucets and shower heads.

    • Traditional faucets use 4 – 7 gallons (of water) per minute (GPM).  Installing low flow faucets or aerators can reduce this to 1 or 0.5 GPM without sacrificing performance.  This saves approximately 7,800 gallons of water per year in an average household.
    • Traditional shower heads use 5 – 8 GPM which means a single 5 minute shower can consume up to 40 gallons of water! Installing low-flow shower heads can save up to 12 gallons of water per shower by bringing the flow rate down to 2 GPM or even 1.5 GPM by using ultra-low-flow faucets.
    • Low-flow faucets and shower heads work by restricting the flow of water while maintaining standard water pressure (approximately 80 psi).  Therefore consumers are able to enjoy the same water pressure while conserving water.
  • These fixtures also reduce energy use by 40%.  Energy is related to water use in several ways: (1) Energy is used to heat hot water, if less water is used, less natural gas or electricity is burned to heat the water, (2) energy is also used to pump water to your faucet and used to pump wastewater (water that goes down the drain) to wastewater treatment plants where more energy is used to treat the water before it is discharged to the environment, if less water is used, less energy is used to pump and treat wastewater. 
  • By reducing the demand for hot water by using low flow shower heads and faucets an average household can cut the emission of 376 pounds and 83 pounds of climate-changing carbon dioxide each year respectively.  Not to mention the savings from treating less wastewater!  [Source: Flex Your Power

Dual Flush Toilets

Dual flush toilets have been installed in Stratton House, Slade Hall, Miller Hall, Kresge Hall and Boylston Halls.

  • Dual Flush Toilets allow the user to choose a small flush and larger flush to accommodate liquid and solid wastes respectively.
    • The small flush uses 0.9 gallons per flush (GPF) while the large flush uses 1.6 GPF. 
    • Standard toilets installed after January 1, 1994 must use no more than 1.6 GPF as stated by Federal law.  Standard toilets installed before 1994 can use as much as 3.5 GPF – 7 GPF.  Installing a dual-flush toilet reduces water use by allowing for a smaller flush (0.9 GPF) for liquid wastes without compromising performance.
