The United Nations has designated March 22 World Water Day, and with that in mind I want to explore new ways to save water. What are some water conservation tips I can apply throughout my facility?
The Alliance for Water Efficiency has provided a comprehensive list of water conservation tips for commercial, industrial, and institutional water use. Here are some suggestions from that source:
Auditing and Benchmarking
Compare water use to industry benchmarks if available.
- Water use benchmarks provide an estimation of the average water use for specific industrial sectors and can be used as a tool to evaluate current consumption patterns among peers.
Conduct a facility audit to quantify water use.
- Understanding water use will identify savings opportunities, allow appropriate savings targets to be established, and serve as a benchmark from which water savings can be tracked.
- This should be the first step in a water efficiency program. It may be cost-beneficial to hire a professional with expertise in industrial water use efficiency to carry out an on-site survey.
Investigate the feasibility of the following general options in your operations.
- Reducing the flow of water.
- Modifying equipment or installing water saving devices.
- Replacing existing equipment with more water-efficient equipment.
- Water treatment, recycling, and reuse.
- Changing to a waterless process.
Learn from water saving success stories of industry peers.
- Case studies from industrial peers will provide insight into what works, what doesn’t, and what efficiency solutions are most cost-effective. These details can often be found in sustainability reports or annual reports.
Install water efficient fixtures in restrooms and showering areas.
- Industrial facilities often have domestic water uses such as toilet flushing, sinks for hand washing, and showering facilities. These represent great opportunities for water savings.
- Examples of fixtures that can be retrofitted include high-efficiency toilets, high-efficiency urinals, faucet aerators in sinks used for hand washing, and efficient showerheads.
Manage on-site laundry facilities efficiently.
- Many industrial and commercial facilities consume a considerable amount of water for laundering.
– For residential style washing machines be sure and select a low water factor. As of January 1, 2011 top and front loading Energy Star clothes washers will be required to have a water factor of 6.0 or less. The Federal standard will be 9.5.
– Multi-load machines should be set to run efficiently with separate settings for each cycle.
– If large volumes of laundry are being processed assess the feasibility of installing a tunnel washer.
– Evaluate costs and benefits for using laundry systems that recycled water or use ozone technology.
Utilize efficient technology in kitchen areas.
- Kitchen facilities are a likely candidate for reducing water use in any facility. The following are items that can be retrofitted:
– Rinse dishes with an efficient pre-rinse spray valve
– Use a dishwasher that meets Energy Star standards
– If a wok is used retrofit it with a waterless wok
– Install in-line flow restrictors for dipper wells. Also look for new water efficient dipper well technology
– Replace boiler based food steamers with boilerless technology
– Strainers can reduce water used by garbage disposals
Educate employees about the importance of using less water.
- Creating a workplace culture that focuses and takes pride in efficiency can be a very beneficial component of a water conservation plan. Increased awareness will ensure more staff members are monitoring water use.
- Things that can be done:
– Give recognition to those who initiate water-efficiency procedures and processes.
– Make resource conservation part of performance reviews, especially for line managers.
