require accurate systems to assess overall water consumption patterns and help identify areas for improvement and water- efficient best practices. These efforts can contribute to the broader sustainability goals of an organization. With traditional submetering, water supplied to a facility or property first goes through the primary meter (also known as the master meter), which measures and provides information on the total volume of water consumption. The limitation of a master meter is that it does not reveal how much and where water is consumed within the location. In some cases, submeters are installed to measure the consumption of specific, water-intensive fixtures such as boilers and irrigation systems. This approach allows facility owners and/or managers to collect the water consumption data of each fixture on their property and thus identify water conservation opportunities. However, large properties, such as buildings, resorts, and factories, can present unique submetering and cost-recovery challenges. The common barriers to this technique include: • Installation cost and high, recurring maintenance expenses • Monthly service charge for specialized assistance with meter reading and allocation • Regulatory issues involving permits, inspections, and fees for submetering equipment • Liability concerns related to system malfunction, leaks, etc. Despite these issues, there are significant incentives for implementing an effective submetering solution. Sub- metering throughout a facility, property, or campus empowers everyone from management to operations staff to make more knowledgeable decisions for more efficient use of valuable fluid resources. It can help facility management address both corporate sustainability goals and rising water costs by monitoring usage levels and implementing water-saving changes to their operations (see Figure 1). Latest Technology Developments Submetering is normally the best way to get a handle on water consumption. While simply installing submeters is effective alone, using advanced water data management technology can quickly optimize any submetering program, making current, exact usage data available to appropriate stakeholders. This, in turn, can reduce water consumption by: • Raising awareness of how much water is consumed over time • Ensuring compliance with local water usage restrictions • Stemming waste from malfunctioning systems By providing facility managers with real-time, automatically generated data, cloud-based software solutions can make monitoring, billing, and reducing water use far easier than with traditional, manual submetering systems. The latest metering systems can analyze consumption on a real-time basis, making it simple not only to track where and when small leaks occur, but also to track patterns of water consumption. In either instance, it allows facilities to be more proactive in addressing consumption- related issues. The current generation of web-enabled flow measurement management system packages advanced software with proven flow measurement technologies and leverages existing cellular network infrastructure for improving management of facility water resources, including domestic hot and cold water, irrigation systems, recreational usage, tenant submetering, HVAC systems, etc. Users often integrate the software platform with other operations and process systems via an application programming interface (API), utilizing secure encryption to ensure data is reliably transmitted and received. Advancements in targeted metering analytics bring new optimizing information to light and put interval meter data to work to address requirements for actionable intelligence and improved operations. New analytic tools offer an overview of the water system through a standard web browser and provide robust status and trend information. The latest end-to-end software solutions include an integrated "dashboard" format with key performance indicators (KPIs) to provide displays, graphs, and charts with crucial data. In addition to delivering fully time-synchronized reads on water consumption, they can generate immediate priority alarms for minor and major flow events, as well as continuous leaks. O&M (operations and maintenance) personnel can view and track water usage online via a computer or mobile device. System displays provide analytics and graphs that incorporate historical data, such as temperature and rainfall overlays, to create a clear picture of how water is currently being used throughout the facility. Intelligent data and analytics applications also empower users at various levels of an organization to identify and quickly address flow inefficiencies, equipment problems, or wasteful FLOWCONTROL wateronline.com n Water Innovations 27 With increased water rates in many regions, commercial and industrial sites are motivated to reduce usage levels and, at the same time, identify leaks and equipment malfunctions.
