The Cost of Water

Billing Meters Sub Meters Metrics Outdoors Landscaping O&M Irrigation
The Cost of Water is deceptively low as building owners and tenants pay for water twice - water supplied + water discharged to the sewer. Additional considerations include the cost of energy required to pump and heat water and rate increases over time from energy and water utilities. Cost control solutions and incentives range from fulfilling water requirements for building certifications, conducting water audits, inclusive of leak detection, to incorporating water efficiency into standard operating procedures and procurement policies.
Billing Issues verify your property’s rate class and meter size, read water meters regularly to verify usage - units and scale of readings should match bills and internal log books.
Water Meters Require Limited Maintenance and Annual Calibration
Bills can cover multiple meters with specific water usage for each; match all meters listed with their location and equipment covered. Record usage individually and ask utilities for credit on sewer charges for water lost to evaporation instead of being discharged to sewer, irrigation and cooling towers.
Meter and Submeter all sources of water to help identify areas for targeted reductions: city potable, reclaimed water and well water. Most facilities have one or two master meters supplying the whole building; others have one meter for an entire campus with multiple buildings. Submeters:
do not have to be on separate utility accounts;
can help identify leaks and equipment inefficiencies or malfunctions.
Water Metrics the sum of all sources: Potable Water from public water systems and classified for human consumption. Reclaimed Water wastewater treatment plant effluent purchased from a public water system. Well Water obtained from wells, bore wells, and other groundwater sources. Natural Freshwater sources that are not municipally supplied, including surface water sources such as lakes or streams. Other Sources rainwater or storm water harvested onsite, sump pump water harvesting, gray water, air-cooling condensate, reject water from water purification systems, water reclaimed onsite, or water from other reuse strategies.
Outdoor Water Usage the amount of water used outdoors is dictated by landscape size and design, the need for supplemental irrigation, management of pools and other facilities. Outdoor water use is a primary driver of peak use.
Landscaping a well-designed, healthy, water-efficient landscape includes healthy soils to promote water infiltration and root growth, appropriate grading with gentle slopes, mulching of landscaped beds to keep soils cool and moist, drought-tolerant, native, or climate/regionally appropriate plant species, minimal turf area.
O&M maintain existing plantings and protect your investment in plants, remove weeds so water is available for desired plants, allow turf grass to grow longer to achieve deeper root growth, make shade and apply less water to shaded areas, minimize water used for other purposes, shut off water features whenever possible, recirculate in water features, sweep, don’t water hard surfaces.
Irrigation install rain shutoff devices or sensors, soil moisture-based control technologies and sprinklers. Maintenance check the system for broken or clogged sprinkler heads, move or adjust sprinkler components to avoid watering pavement, install and monitor water submeters for irrigation systems, monitor monthly use trends, audit irrigation system every three years.
