Intent

To reduce or eliminate the use of potable water for non-potable process use in building system equipment.

Requirements

When a food waste disposer system is used, the following requirements must be met:

  • Use cold water. (This is a common code requirement.)
  • Equip systems with a load sensing device that regulates the water use to 1 gpm in a no- load situation and 3 to 8 gpm in a full-load situation.
  • Automatic time shutoff that shall have a ten-minute time-out system with a push button to reactivate.

When pulpers, extractors, scrap basket or strainer-type systems are used, the following requirements must be met:

  • Mechanical pulpers/extractors and mechanical scrapper systems shall use no more than 2 gpm of potable water, excluding end-of-day, wash-down cycles.
  • Non-mechanical strainer (scrapper) baskets shall not be part of a flowing trough collection system connected to potable water at a rate greater than 2 gpm.
  • Automatic time shutoff that shall have a ten-minute time-out system with a push button to reactivate.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
