San Francisco began to roll out its new ‘smart’ water meters to city residences this month. The new devices can accurately track water usage in real-time and the San Francisco Public Utilities Commission (SFPUC) plans to make personal water use data available to customers online. Other benefits include the streamlining of operations- meters communicate wirelessly, eliminating the need for house-to-house readings- and the early detection of system leaks and unusual usage surges.
The SFPUC will replace over 175,000 meters beginning with 5,000 this spring/summer,with an estimated install completion for the full number by 2012. The expectation is that the new meters will be able to assist individual and system-wide conservation efforts, increase response time for problems, and allow for a more accurate and refined fee structure.
California, as a drought-prone state, can stand to benefit greatly from increased water use data collection. As it stands today, water use is not uniformly tracked in all homes and businesses, nor is there any correlation between regional water scarcity and water service rates. While agriculture, industry and conveyance also play leading roles in the general water picture in the state, having accurate home and commercial usage data is a step forward, and can only be a benefit in creating sound management policies for this precious and scarce resource.
