A large municipal water utility in the southwest operates multiple facilities that provide more than 170 MGD of drinking water to residents and businesses. The utility, which spans 100 square miles, is prone to leaky pipes because parts of its distribution system have been in place for nearly a century. Also known as non-revenue water, or NRW, these leaks significantly drive up the cost of production.
Non-revenue water loss is a problem from coast to coast, but California has taken a lead and set an example — with resources from AWWA — by adopting and sharing best practices to help solve the issue.
Most utilities understand they have a nonrevenue water problem, but few know how to deal with it correctly. Start by learning more about how the issue affects your utility and what options are available.
Non-revenue water (NRW) and, in particular, water loss through leakage has become an increasing priority focus for water utilities around the world. With failure rates of aging infrastructure increasing and growing water stress due to population growth and climate change, reducing the loss of essential water resources is paramount. Leak monitoring and detection systems from Trimble Water help water utilities proactively identify and reduce NRW and water loss, prevent service outages, and prioritize infrastructure repairs. Easy-to-use wireless and mobile leak detection solutions provide clear, accurate, real-time insights into the condition of the water network beyond the treatment plant. Paired with Trimble’s intuitive cloud-based GIS software, Trimble’s solutions make it simple for water professionals to visualize, manage, and analyze data from the field and use that knowledge to improve productivity and network performance.
The City of Dallas captured an additional 600,000 gallons of billable water in four months.
When the New York City Department of Environmental Protection (DEP) implemented a STAR® network system to read meters for its nine million customers, it never expected that the benefits of the system would extend beyond simple meter reading.
The Water Department in the City of Redmond, which serves approximately 28,000 residents, needed to streamline its process of collecting meter reads to save costs and improve data integrity.
Water loss control can be challenging, confusing, and time-consuming. Effective water loss control requires a multi-step process, including water audit (also referred to as a water balance), component analysis and intervention.
This is the time of the year for ghouls, goblins, and things that go bump in the night. Of all the scary things that your water utility might confront on all hallows ‘eve, however, the most chilling might be unforeseen non-revenue water losses from leaks, theft or meter inaccuracies.
In 2017, Orlando residents saw firsthand the negative effects of what could happen when a construction crew caused a major water main break downtown. Not only did the leak become an inconvenience for the city, but it also was expensive to repair.
The Leak Sensor is an advanced approach to distribution system leak detection. Part of Itron's ChoiceConnect Fixed Network advanced metering solution, the sensor is the result of merging the 100W communications module module with an acoustic sensor to create a single point for collecting meter data and monitoring for distribution system leaks.
Aclara’s through-the-lid antenna lets you install Aclara Meter Transmission Units (MTUs) while retaining metal pit lids. Our flexible install options mean our MTUs will work whether you reuse current metal lids or replace them with RF-permeable ones.
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
A hard-wired and entry-level version of the Mikron3 that enhances all leak detection kits.
Leak detection isn’t a one-time activity. Our leak detection programs help clients evaluate the integrity of their water network by locating and pinpointing leakage. This service is included in the “Infrastructure Management” part of our Risk Management services. Leak detection services are executed on potable waterlines and pipes of all materials and sizes. We can also implement non-invasive methodology and do internal pipe leak detection services.
A proven technology platform designed to monitor water transmission mains.
This video explains how Aquis Leak Detection can reduce the amount of Non-revenue Water by reducing loss of water through existing leaks and reduce the risk of additional leaks. Furthermore energy consumption, emissions and use of chemicals are reduced and water quality is improved.
