SACRAMENTO, Calif.–(BUSINESS WIRE)–Electro Scan, Inc. announced its sponsorship of seven (7) statewide workshops on Water Leak Detection that begin this week in California.

“We are delighted to sponsor these timely workshops organized by the California-Nevada Section of the American Water Works Association,” said Chuck Hansen, Chairman, Electro Scan Inc.

Workshops cost $25 to attend and will describe steps a water utility can take to help reduce their non-revenue water and mitigate real water losses through a comprehensive leak detection program.

Workshop dates & locations include:

Tuesday, February 9 – Thousand Oaks, CA
Wednesday, February 10 – South Gate, CA
Thursday, February 11 – Escondido, CA
Wednesday, February 17 – West Sacramento, CA
Thursday, February 18 – Redding, CA
Tuesday, March 29 – Coachella, CA
Wednesday, March 30 – Fountain Valley, CA

Water utilities have come under increased scrutiny for maintaining water quality, eliminating water losses, and upgrading its aging infrastructure to protect and safeguard public health.

“In the past, acoustic sensors were used to locate general anomalies that might leak,” said Mark Grabowski, Vice President and General Manager, Electro Scan Inc.

“But, false-positive readings from road traffic, poor data repeatability, and reliance on third party data interpretation, have limited their usefulness,” continued Grabowski.

Many utilities replace old pipes with high performance plastic pipes – such as PVC, Polyethylene, and High-Density Polyethylene pipes – that represent quieter materials that do not adequately transmit sound or vibrations to detect anomalies or leaks.

As a result, private investment has focused on developing new technologies that would greatly improve the accuracy and reliability of water main condition assessment.

Referred to as Low Voltage Conductivity Testing or Electro Scanning Inspection, Electro Scan’s Smart Water technology represents the first repeatable and measurable way to locate and quantify water main leaks in gallons per minute (GPM).

“Clean technologies, like Electro Scan, are changing the way utilities find and measure leaks in Pressurized Water Mains,” said Hansen, a water industry veteran.

Provided as an exclusive service to detect leaks often not found or measured by other techniques, the company uses its patent-pending 4-in-1 multi-sensor probe that features:

  1. Low Voltage Conductivity Sensor – To measure individual leaks and quantify total water losses utilizing a low voltage conductivity tri-electrode array to find leaking cracks, pinholes, defective joints, bad service connections, and other openings to ground.
  2. High Definition CCTV Camera – To assist operators in navigating through water mains and to document leak locations found by low voltage conductivity sensor.
  3. Pressure Sensor – To provide location-specific water pressures for calculating water loss rates.
  4. Acoustic Sensor – To record sound vibrations and provide a benchmark of legacy results that can be readily compared to low voltage conductivity results.

In December 2015, Electro Scanning Inspection was added to the new edition of the wastewater industry’s leading operation and maintenance manual, recommending its use over closed-circuit television (CCTV) inspection to find infiltration and to certify post-rehabilitated pipes.

For water main assessments, the company uses a neutrally buoyant fiber optic cable attached to its 4-in-1 probe to evaluate up to 2,000ft of water main from a single point of entry, accessing the main through fire hydrants, air valves, flow meters, gate valves, and pressure fittings.

In September 2015, Governor Jerry Brown signed into law (SB 555) one of the toughest reporting requirements in the nation, mandating all California water utilities to audit, report, and manage real water losses.

A company representative will attend each workshop to discuss its services, recommend budget costs, and share information about its CriticalH2O cloud reporting system.

“If a pipe leaks electricity, it leaks water,” said Hansen. “And, now we can both locate and estimate each leak’s water loss in GPM”
