EPA’s Water Management Techniques for Labs

EPA’s Water Management Techniques for Labs

The U.S. Environmental Protection Agency (EPA) has recently shared ten ways to effectively manage usage in laboratories. Developed by the Sustainable Facilities Practices Branch, the list includes:

  1. Metering and measuring to analyze a facility’s water usage and managing mechanical equipment for greater water efficiency. By doing so, facilities are able to prevent excess water usage caused by malfunctioning mechanical equipment.

  1. Optimizing cooling towers by controlling the ratio of the quantity of water evaporated to the quantity of water discharged.

  1. Using high efficiency plumbing fixtures including waterless urinals,low-flow toilets, and faucet flow control. These systems aid smarter water usage in facilities by avoiding necessary water usage.

  1. Eliminating single-pass cooling which uses a continuous flow of water that is circulated once through the system for cooling purposes and is then disposed of down the drain.

  1. Incorporating Xeriscaping or using water-efficient plants rather than water-intensive ones to minimize the need for irrigation.

  1. Using improved operational controls or retrofitting steam sterilizers to avoid unnecessarily discharging a continuous flow of tempering water down the drain.

  1. Diverting used aquatic culture back into bodies of water instead of sewers.

  1. Controlling reverse osmosis system operation and carefully regulating de-ionized water generation rates.

  1. Recovering rooftop rainwater and using it for flushing toilets, supplying cooling towers, irrigating landscape, and more.

  1. Recovering air handler condensate and then using it for cooling towers and other applications in and around the facility.
