Water Efficiency
Buildings are major users of our potable water supply. The goal of the Water Efficiency category
is to encourage smarter use of water, inside and out. Water reduction is typically achieved through
more efficient appliances, fixtures and fittings inside and water-conscious landscaping outside.

Low Flow Restroom Fixtures
Project Overview
The Airport’s restrooms were using outdated fixtures that required a lot
of water usage. Incorporating recent water-saving fixtures reduced
restroom water usage by a weighted average of approximately 50%.
• Before Construction
• Toilets: 3 gallons per minute (gpm)
• Urinals: 1gpm
• Faucets: 2gpm
• After Construction
• Toilets: 1.5 gpm
• Urinals: 0.5 gpm
• Faucets: 0.5 gpm

• The Airport’s bathrooms were in need of renovations. The decision
was made to implement efficient flush valves during the renovation.
• A significant environmental improvement is less water is distributed
to the local waste water treatment plant (WWTP), which in turn causes
less water to be pulled from the local river.
• There are many other indirect significant environmental benefits to
low-flow fixtures, such as environmental restoration, less energy used
at WWTP, conservation awareness and less restroom repair problems.

SUSTAINABILITY PROJECTS
Profile Sheet
Water Efficient Landscaping
Project Overview
CLT’s Field Maintenance landscape supervisor used a number of methods to
promote efficient water use throughout Airport property including ground
preparation improvements and installing water-wise plant material. To create
rich, well-draining conditions, staff used locally produced organic compost and
aged pine bark fines to prepare grounds for plant materials. This foundation
promotes thicker, deeper and more extensive root systems that are more drought
resistant. Additionally, this type of ground preparation encourages moisture
retention to combat dry spells while also preventing “boggy areas”.
Another key component to CLT’s water efficient landscaping included the
selection of water wise plant material. In an effort to increase a plant’s
adaptability to a new location, the landscaping team ensured plant material was
appropriately matched with a potential site’s microclimate. Using this method,
none of the newly installed plant material should receive supplemental watering
after their first year of adjustment.

In the future, all new plant material will be selected to ensure it is drought tolerant
and that approximately 75 percent of the Airport’s landscape materials are native
to the region.
