The City of Walla Walla in Washington has detected 2,000 water leaks in the first year of deploying a smart utility network.

 

“As our pipes failed and water meters aged, we began to see a 30 per cent annual water loss, which is significant given that we distribute about three billion gallons of water each year,” said City of Walla Walla water distribution supervisor, Adrian Sutor.

 

The city implemented residential and commercial water meters from Sensus across 11,000 water accounts. These were paired with a two-way communication network for near real-time remote monitoring.

 

“We detected more than 2,000 leaks in the first year of deployment and promptly alerted each customer of any issues, which greatly improved our customer service,” said Sutor.

 

Extending the network

 

The city also deployed pressure monitoring and management tools across residential accounts to provide data insights on pressure, temperature, levels and switches.

 

“By reducing water loss and cutting down the carbon footprint associated with truck rolls, we [are] well on our way to becoming more sustainable as a utility,” said Sutor.

 

“We detected more than 2,000 leaks in the first year of deployment and promptly alerted each customer of any issues, which greatly improved our customer service.”

 

Walla Walla has now added applications for creek-level monitoring, district metering and remote shut-off on the same network it uses for smart metering. It plans to extend the network to include stormwater and wastewater accounts.

 

“The City of Walla Walla exemplifies the power of technology and data to address the water infrastructure challenges our country is facing,” said Colin Sabol, president, measurement and control solutions at Xylem, which owns the Sensus brand. “As much of Washington faces drought conditions, Walla Walla is taking a proactive stance to ensure a more water-secure future for us all.”
