Commercial / Industrial Water conservation
Commercial and Industrial
Standard practices for the commercial and industrial water use sector:
- Facility audits on an annual basis. Results of these audits should pinpoint the changes that can increase water use efficiency.
- Metering and sub-metering should be considered when possible and the implementation of a leak detection program can be helpful in locating lost and unaccounted for water. For specific advances in municipal, commercial, and industrial water use technologies refer to Water Efficient Technologies.
Recommendations for outdoor water use by industrial and commercial facilities:
- Graywater reuse
- Water harvesting
- Landscape conversion (turf removal, conversion to low water use landscaping)
- Installing Xeriscapes in new landscapes (multi-family, non-residential, and/or common areas)
- Water tampering / water waste ordinances
- Limitations on water intensive landscaping and turf
- Car wash water recycling
- Landscape watering restrictions (time of day, etc.)
- Irrigation efficiency standards for non-residential users
- Use of the best available conservation technology
- Implementation of smart irrigation technology
Industrial
Some examples of industrial uses include:
- Turf-related facilities (facilities of 10 or more acres of water intensive landscaping)
- Dairy operations and feedlots
- Cooling towers and electrical power plants
- Sand and gravel facilities
Categories of conservation requirements are:
- General industrial conservation requirements, which apply to all industrial users
- Turf-related facilities have and annual allotment based upon the number of acres of turf, bodies of water, and low water use landscaping
- Sand and gravel facilities, which have operating standards must develop a conservation plan
- Large-scale power plants, which have water efficiency standards for their cooling towers
- Large-scale cooling facilities, which have water efficiency standards
- Dairy operations, which have an annual allotment based on herd size, or may apply for a Best Management Practices program
- Cattle feedlot operations, which have an annual allotment based on herd size
- New large landscape users, which have landscape efficiency design standards
- New large industrial users, which have water use efficiency and conservation plan requirements
Some techniques that are recommended for achieving water conservation in the industrial sector are:
- Reusing or recycling water
- Avoiding single-pass cooling unless the water is reused
- Use of low flow plumbing fixtures
- Use of low water use landscaping with efficient irrigation systems
- Developing site-specific water conservation plans for large facilities
Commercial
Some examples of commercial uses include:
- Restaurants and eateries
- Hospitals and veterinary clinics
- Car washes and gasoline service stations
- Shopping centers, stores, and malls
