Sanitary Sewer Overflows (SSOs) May Be Linked to Outdated CCTV Technology & Faulty Inspections

Findings Presented to California’s Leading Environmental Agency Show Citizens May Be at Risk Due to Slow Investment in Innovative Technologies That Accurately Identify Bad Sewers

Sacramento, Calif. – (BUSINESS WIRE) – Sanitary Sewer Overflows (SSOs) being experienced by California cities and counties may be due to reliance on older visual-based technologies and faulty inspections by city crews and independent contractors.

Those were the findings recently presented by Sacramento-based Electro Scan Inc. to the California Environmental Protection Agency (CalEPA), State Water Resources Control Board, Office of Enforcement as part of their ongoing technical forum with outside consultants & vendors to support state & regional inspectors.

As a result, the Office of Enforcement plans on encouraging Regional Water Boards to see Electro Scanning Inspection at various upcoming project and demonstration locations throughout California.

“California’s record rainfall has put a spotlight on sewer agencies that have not made the necessary investment in new technologies needed to combat SSOs,” states Chuck Hansen, former Chair, ASTM’s Inspection and Renewal of Water and Wastewater Infrastructure Committee and Chairman, Electro Scan Inc.

“Traditionally, cities have relied on Closed-Circuit Television (CCTV) cameras – a visual-based inspection technique – to identify and catalog cracks, defective joints, and poorly connected service connections,” states Hansen, an expert in pipe condition assessment.

“But, the inability to differentiate superficial cracks from cracks that go through a pipe wall, have frustrated efforts to accurately prioritize critical pipes and certify repairs, contributing to SSOs and flooding,” states Hansen.

California SSOs are tracked statewide by an interactive map maintained by the CalEPA State Water Resource Control Board.

Studies conducted by Electro Scan included work at over sixty (60) California sewer agencies where CCTV inspection results were compared to an innovative machine-intelligent technology that accurately locates and measures defects.

Highlighted findings presented to the State Water Board’s Office of Enforcement, included:

  • One study that found CCTV inspections had missed eighty-eight percent (88%) of all sewer defects, including several CCTV reports on the same pipe that showed materially different assessments, completed by the same person working for the same company, just months apart.
  • Several agencies with major defects in recently repaired sewers – leaking more after repair, than before repair.
  • Major damage in a newly lined pipe caused by a Contractor’s acceptance inspection; however, its final report showed ‘Zero Defects.’
  • Two connected pipes that showed the newly relined pipe leaking more than the existing 50-year old pipe; both certified by CCTV inspection.
  • A Northern California agency showing ‘Zero Defects’ on a sewer located in an area prone to flooding. Yet, on re-inspection, the pipe was more than half-full of water – on a clear day, mid-week, and in mid-afternoon – showing major leaks at every joint, undetected by CCTV inspection.
  • A re-inspected sewer with an 11-million-gallon water main break; missed by two previous CCTV inspections conducted in 2011 and 2014. One survey had been conducted by an independent contractor, while another was completed by city staff, respectively.

Referred by the USEPA as Focused Electrode Leak Location (FELL) inspection, the new inspection standard is being adopted by leading sewer utilities to provide an unbiased way to find sources of infiltration and to certify repairs.

Using the new technology, no operator judgment or third-party data interpretation is required, with each defect provided with an estimated defect flow in gallons per minute.

In December 2015, new guidelines were published for Inspecting and Testing Collection Systems, Seventh Edition, Volume 1, OPERATIONS AND MAINTENANCE OF WASTEWATER COLLECTION SYSTEMS, ISBN 978-1-59371-066-8, recommending Electro Scanning Inspection, in place of CCTV inspection, to assess all pre- and post-repair, rehabilitation, and relining projects.

In the first twelve months of the new inspection standard, Electro Scan found defects in 69% of Cured-In-Place Pipe (CIPP) – a leading alternative to dig and replace pipe rehabilitation – traditionally inspected by visual inspection.

Overall, 21% of CIPP surveyed in 2016 using new testing standards had defect flows of 20 gallons or more, after rehabilitation.

“CCTV was the best we had for a long time, but now there is a better tool to certify point repairs, service reconnections, and trenchless rehabilitation,” states Hansen.

Since December 2016, the San Francisco Public Utilities Commission (SFPUC) and the City of San Francisco Department of Public Works have issued public bids worth over $23 million requiring FELL as its new acceptance and certification standard to ensure delivery of leak-free rehabilitation projects.

The next generation technology uses a high frequency, low voltage, focused electric current to evaluate 360-degrees of a pipe wall to find and measure openings that provide a clear path for water to enter or exit a pipe through defects.

Tested by several independent studies funded by the US EPA, the new technology is compliant with ASTM F2550-13 Standard Practice for Locating Leaks in Sewer Pipes By Measuring the Variation of Electric Current Flow Through the Pipe Wall.

In addition to numerous benefits over CCTV Inspection, Electro Scan products also show superior results in comparison to acoustic sensors, electro-magnetic, ground penetrating radar, helium tracers, laser profiling, sonar, and zoom cameras, for leak detection.

Equipment to evaluate sewers ranging from 3 to 30 inches in pipe diameter may be purchased directly from the Company and added to a variety of existing CCTV trucks or vans.

Services are offered worldwide from the Company or an Authorized Partner.

Prior to founding Electro Scan Inc., Hansen was founder and former Chairman of Hansen Information Technologies. Founded in 1983, Hansen was a leading provider of asset management solutions for water and sewer utilities, and developed the State of California’s Department of Transportation (Caltrans) work management system.

Electro Scan Integrates with  Innovyze InfoMaster

Sacramento, Calif. – (BUSINESS WIRE) – Electro Scan Inc.­ has completed data integration between its flagship sewer condition assessment solution and the Innovyze® InfoMaster for Sewer product.

Electro Scan’s breakthrough technology evaluates 360-degrees of a pipe wall to accurately locate and measure defects in gallons per minute (GPM) or liters per second (l/s).

Recent studies indicate that 70-100% of defects are typically not found by legacy inspection techniques, such as closed-circuit television (CCTV) inspection, smoke testing, dye flood testing, laser profiling, and acoustic sensors.

Recommended to assess and certify pre- and post-rehabilitated pipes, a new chapter was recently added on Electro Scanning Inspection to the industry’s leading training manual, Operation and Maintenance of Wastewater Collection Systems, Seventh Edition, Volume One (2015), in accordance with ASTM F2550.

“We are delighted to integrate our game-changing pipe condition assessment solution with the leading business analytics solution for the wastewater industry,” states Chuck Hansen, Founder and CEO, Electro Scan Inc.

“The Innovyze® family of smart network modeling and asset management solutions continues to be the standard platform for existing and emerging diagnostic tools,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, Dist.M.ASCE, NAE, President, COO and Chief Innovation Officer of Innovyze.

“We look forward to offering this new layer of condition assessment data to help our clients in their sewer rehabilitation decisions,” continues Boulos.

Electro Scan’s Critical Sewers® cloud application allows for up-to-the-minute monitoring of sewer evaluations, lining projects, point repairs, and new construction projects, while crews are still in the field.

Clients can easily identify pipe-specific problems before rehabilitation project acceptance.

Wirelessly transmitted to the Company’s award winning cloud application, defect flows are reported in minutes and incorporated into Innovyze® InfoMaster for Sewer product for display and analysis.

Since Electro Scan’s advanced low voltage conductivity technology does not rely on operator interpretation, third-party data analysis, or independent judgment, a key advantage is its ability to automatically provide specific location, size, and estimated flow for each defect and total pipe.

Customers wishing to utilize Electro Scan’s decision support data must be licensed users of Innovyze® InfoMaster for Sewer and Electro Scan’s Critical Sewers® cloud application, including associated integration module.

Once data is accessible, Electro Scan defect flows may be highlighted by location and severity by Innovyze® InfoMaster for Sewer, including the identification of defective joints, cracks, and leaking service connections, compared to CCTV inspection results.

Electro Scan and Innovyze® users can show pipe defects ranked by highest GPM and gallons per day per inch diameter mile (GPD/IDM), utilizing Innovyze’s 1D and 2D modeling and mapping features within Innovyze® InfoMaster for Sewer product.

Electro Scan & WRc Exhibit at No-Dig Live in the UK

Electro Scan and WRc Exhibit at No-Dig 2016, September 20-22, Peterborough, England

WRc Electro Scan Van

London, England – September, 15, 2016 – Electro Scan Inc., a global leader in pipe assessment, in partnership with WRc plc, is delighted to showcase its Electro Scanning Services capabilities for UK sewerage condition assessment at No-Dig Live 2016, September 20-22 in Peterborough, England.

First meeting at the 2015 United Kingdom Society of Trenchless Technology (UKSTT) Awards Gala in Birmingham, after receiving separate awards for achievement, a strategic agreement was negotiated with WRc’s Business Services Unit to become the exclusive provider of Electro Scan Services throughout the United Kingdom and Republic of Ireland.

The teaming of Electro Scan and WRc was announced nearly a year ago with several projects already completed.

WRc Master Class

Electro Scan represents a next generation condition assessment technology that automatically locates and measures leaks in gravity mains and stormwater pipes.

Providing specific locations for each defect, the innovative technology provides an estimated defect flow in either gallons per minute or liters per second – for each defect and total sewer main.

By providing a baseline defect flow, before rehabilitation, Electro Scan can quantify a specific reduction in flow and certify trenchless repairs as ‘leak-free,’ prior to contractor acceptance.

Results are reliable, repeatable, and unambiguous, with data available within minutes after completing each survey.

No operator coding or third party interpretation is required, often finding defects not identified by visual inspection.

Unlike CCTV, it does not rely on a subjective visual observation – so even pipes that are fully surcharged can be assessed.

Data can also be integrated with the Innovyze® InfoMaster® for Sewer program for catchment planning.

Recommended by recently published standards and used by leading sewer agencies for pre- and post-rehabilitation assessment, WRc is spearheading Electro Scan Services in the UK to help address requirements in AMP6 among UK water and sewer companies.

Keith Walker, Head of Commercial Enterprise at WRc comments, “Electro Scan’s advanced technology combined with the experience and proven consultancy of WRc, make the partnership well positioned to bring the next frontier of innovative solutions to UK water clients.”

Electro Scan Experiences Rapid Adoption in Northern California

Rapid Adoption of Electro Scan Inspection By Northern California Sewer Agencies Follows Release of New Wastewater Guidelines

New Projects Address Violations of the Clean Water Act and Mandatory Reductions in Sanitary Sewer Overflows

SACRAMENTO, Calif. – June 13, 2016 – Electro Scan Inc. has begun numerous projects in Northern California to independently assess the condition of sanitary sewers, before and after rehabilitation programs.

SF Bay Area

“We are delighted to begin so many projects near our headquarters,” stated Chuck Hansen, Chairman of Electro Scan, “and to show how sewer agencies can reduce their reliance on outdated methods of inspection that may inaccurately prioritize defects and are unable to certify repairs.”

One recent survey compared sewer mains that were previously inspected using high-resolution cameras; however, closed-circuit television (CCTV) recorded less than 1 of every 10 defects found using Electro Scan Inspection.

In another, the majority of CCTV inspections rated pipes as ‘leak free’ or having no evidence of infiltration, with Electro Scan Inspection finding major leaks in over eighty percent (80%) of the pipes surveyed.

In previous surveys, visual inspections simply recorded factory tap locations that connect homes to the sewer main, without recording any defects. In contrast, Electro Scan Inspection automatically located and quantified leaks at each defective service connection.

Authored by the late Ken Kerri, Ph.D., PE, the Electro Scanning Inspection chapter was included in the new Seventh Edition, Volume One, Operation and Maintenance of Wastewater Collection Systems manual to overcome the limitations of visual inspection. The new manual now recommends the use of Electro Scanning Inspection, over CCTV, to evaluate sewer and stormwater pipes, both before and after rehabilitation.

“Sewer managers have long acknowledged the drawbacks of using visual inspection to rate the condition of sewers,” commented Hansen. “But, what surprises most people are the high number of defects found by Electro Scan in relining and point repair projects that were missed by CCTV inspection.”

Common defects in CIPP liners, not typically seen by visual inspection, include accidental cuts, accelerator burns, bad service reconnections, equipment damage, defective epoxy, over-cooking, and lining wrinkles that should be repaired or replaced before project acceptance.

Electro Scanning Inspection can be a contracted service or municipal sewer agencies can purchase equipment that can easily be added to an existing CCTV truck, able to switch from CCTV to Electro Scan, and back, in minutes.

Another recent project performed for a community on the Sacramento River Delta, assessed nearly 13,000 ft of pipe consisting of seventy-seven (77) sewer mains. Fieldwork was completed in 4 days.

In a single day, Electro Scan crews completed the evaluation of 3,978 feet or 28 sewer mains – a company milestone – including several difficult access points where several manholes were 40-ft deep and others located in the middle of a dry creek bed.

In December 2015, the first Electro Scan Leak Detection Van was delivered to San Francisco Public Utilities Commission (SFPUC), with 10 trainees achieving Electro Scan Certification in January 2016.

Today, SFPUC has a full-time team dedicated to running their Electro Scan Leak Detection Van to pinpoint pipe defects where seawater enters its combined sewer system.

Electro Scan Inspection uses patented technology to measure the variation of electrical current that flows through cracks, bad joints, defective service connections, and other defects in non-conductive pipes and estimates the amount of leakage in sewer, water, and gas pipelines.

Using its Critical Sewers® cloud application, defects are automatically located and measured in gallons per minute, with unambiguous reports available in minutes.

All Northern California Electro Scanning Inspection projects are being conducted by certified company field crews, in accordance with recommended guidelines published in the Seventh Edition, Volume One, of the Operation and Maintenance of Wastewater Collection Systems manual and in accordance with ASTM F2550-13.

Billions May Be Wasted on Sewer & Water Repairs

ELectro Scan Technology Finds Leaking Infrastructure Before & After Rehabilitation Projects

Sacramento, Calif. – May 10, 2016 – City councils, public works departments, and utilities may be replacing leaking sewer and water pipes with new pipes that leak as much – or more – than the old ones.

Recent studies also suggest that Closed-Circuit Television (CCTV) and other legacy inspection techniques may be causing engineers to design and implement rehabilitation strategies for the wrong pipes.

Those are the findings from a California-based company that has developed new technology that finds and measures defects in cement, concrete, plastic, and relined pipes that deliver or transport sewer, water, and natural gas.

With billions spent annually to fix crumbling infrastructure, a recent poll found that 46% of respondents encountered significant defects after rehabilitation.

“Today’s pipes are supplied within generally accepted industry specifications,” says Chuck Hansen, Chairman, Electro Scan.

“But, defects from improper installation and faulty service re-connections – not seen by current inspection techniques – often cause leaking pipes to be unknowingly accepted by utilities,” continues Hansen.

Problems are often not found until after a warranty expires.

Last week, Trenchless Technology magazine, a leading publication serving the underground infrastructure market, and Electro Scan Inc., conducted a webinar that highlighted a city that recently completed a 5,500-foot Cured-In-Place Pipe (CIPP) lining project.

Using Electro Scanning Inspection, it was found that 1,066 ft or 19% of the project had more leakage after rehabilitation.

“Defects not typically found, include bad service connections, cracks that go through a pipe wall, defective joints, and faulty point repairs,” states Henry Gregory, former Assistant Deputy Director, City of Houston and Special Advisor to Electro Scan.

The new technology uses a focused low voltage current to evaluate 360-degrees of a pipe wall to find and measure openings that provide a clear pathway through a pipe.

Results are available in minutes on a cloud-based application.

Equipment can be purchased from the Company and added to existing CCTV trucks or vans, with services offered either by the Company or Authorized Partner.

New CMOM, SSES, and Pipe Rehabilitation Guidelines

New Sewer & Water Assessment and Pipe Rehabilitation Certification Guidelines Unveiled at 2016 NASTT Show

Electro Scanning Inspection Recommended to Certify Trenchless Lining and New Installations

Sacramento, Calif. – March 11, 2016 – Electro Scan, Inc. announced that it will unveil new certification standards for sewer and water pipe rehabilitation at the 2016 NASTT Show.

New guidelines emerged after finding that major defects were consistently not found using Closed Circuit Television (CCTV) inspection, prior to the acceptance of Cured-in-Place Pipe (CIPP) lining and Sewer Survey Evaluation Studies (SSES) projects.

Defects not identified or accurately measured by visual inspection, include accelerator burns, bad service connections, cracks, cuts, defective inverts, over-cooking, and wrinkles – causing increased maintenance and severely reducing the useful life of the asset, if not properly fixed by the Contractor.

In contrast, new guidelines recommend locating and estimating the size of each defect – in gallons per minute – by measuring the variation in electric current able to pass through each defect or opening, in accordance with ASTM F2550.

New standards of practice were recently added to Chapter 4, Inspecting and Testing Collection Systems, in the industry’s leading manual, Volume 1, Operation and Maintenance of Wastewater Collection Systems, Seventh Edition, recommending the use of Electro Scanning Inspection, published December 2015.

Co-authored by the late Ken Kerri, Ph.D., P.E., Office of Water Programs, Dr. Kerri concluded that while CCTV inspection provides good visual documentation of sewer maintenance issues, like grease, roots, and debris, CCTV is not the best choice to provide an accurate structural assessment of sewer mains or service laterals, especially given the advantages of Electro Scanning Inspection for certifying CIPP rehabilitation and SSES projects.

Volume 1 & 2 of the O&M Wastewater Collection manual, originally introduced in the 1970s, is referenced in the EPA’s Capacity, Management, Operation, and Maintenance (CMOM) Program.

A key advantage of using Electro Scanning Inspection is its ability to automatically differentiate between superficial surface cracks – that do not leak – and cracks or defects that extend completely through a pipe or liner – that represent major leaks.

Common remedies to fix defects identified by Electro Scanning Inspection include liner or pipe removal & replacement and trenchless point repair.

Utilities are recommended to reference ASTM F2550-13, Section 8.5.1 and the Operation and Maintenance of Wastewater Collection Systems manual, Section 4.40-4.45, to certify any pipe repair, relining, or renewal project.

During the conference, Electro Scan will also discuss its new Water Leak Detection Services – incorporating its low voltage conductivity expertise as part of its patent-pending Multi-Sensor Water Probe – designed for pressurized water mains and transmission pipes.

Electro Scanning Inspection, also called Low Voltage Conductivity Testing, is expected to be included in the upcoming AWWA M77 Water Main Condition Standard of Practice later this year.

Founded in 1990, the North American Society for Trenchless Technology (NASTT) promotes responsible ways to manage underground infrastructure.

The conference will be held March 20-24, 2016 at the Gaylord Texan Convention Center, Grapevine, Texas.

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”

Electro Scan Opens New Office in Miami, Florida

 

 

EPA Enforcement Actions and New Wastewater Collection Inspection Standards Create Strong Demand for Electro Scan Sales & Contract Services

Miami, FL – February 1, 2016 – Electro Scan Florida, LLC announced the opening of new headquarters in Miami, Florida to support growing equipment sales and contract services in the Sunshine State.

Electro Scan customers in Florida include the City of Tallahassee and Miami-Dade Water and Sewer Department.

“Statewide enforcement actions by the U.S. Environmental Protection Agency (EPA) and the release of new wastewater collection inspection standards – published in the industry’s leading manual – have increased demand for our game-changing products and services,” states Chuck Hansen, Director, Electro Scan Florida, LLC and Founder, Electro Scan, Inc.

First published in 1976 with 90,000 copies in print, Electro Scanning Inspection was added to Chapter 4: Inspecting and Testing Collection Systems, OPERATION AND MAINTENANCE OF WASTEWATER COLLECTION SYSTEMS, VOLUME 1, SEVENTH EDITION, released December 2015.

The section on Electro Scanning Inspection recommends new standards to find & measure sewer pipe defects missed by closed-circuit television (CCTV) inspection.

“In the past, wastewater collection managers were limited to visually inspecting and manually cataloging defects,” states Hansen, an early developer of CCTV standards.

According to Hansen, “Most sewer defects can’t be measured or seen by high resolution cameras. In fact, CCTV inspection has never been able to calculate leakage from cracks, bad joints, or defective service connections, needed to prioritize or certify repairs. Electro Scanning Inspection provides the missing piece.”

Using low voltage electric current, Electro Scanning Inspection represents the first reliable, repeatable, and measurable way to automatically locate and quantify sewer and water leaks in gallons per minute (GPM).

No third party data interpretation, operator judgment, or defect coding is required.

Since 1987, the EPA provided $111 billion in low-interest loans through its Clean Water State Revolving Fund to help finance infrastructure upgrades.

Last month, the EPA released a survey showing that an additional $271 billion is needed to maintain and improve the nation’s wastewater infrastructure.

Customers, bondholders, and credit rating agencies will immediately benefit from new standards to certify cured-in-place pipe (CIPP) lining, point repairs, and construction projects.

“Given the use of Electro Scanning Inspection as the new acceptance criteria for pre- and post-rehabilitated pipes, sewer agencies should call us for recommended language to revise bid specifications to include our smart products or contract services,” states Hansen.

Electro Scanning Inspection finds defects that allow water to enter sewer pipes [infiltration] – contributing to backups, flooding, and sanitary sewer overflows (SSOs),” states Carissa Boudwin, Director of Marketing, Electro Scan.

“It is also the only technology that finds leaking sewers [exfiltration] within the cone of influence of Florida’s aquifers,” continues Boudwin. “And, nobody wants to be on the evening news issuing ‘boil water’ notices.”

Agencies may either purchase the company’s patented equipment – easily added to CCTV trucks – or contract directly with the company for professional services.

Recently, Electro Scan expanded its service offering to include Pressurized Water Mains, finding water losses typically missed by permanent and temporary acoustic sensors.

The company’s office is located at 7950 NW 53rd Street, Suite 337, Miami, FL, 33166.
