HUSA Performs Water Studies Across Country
Posted on December 30th 2011
HUSA recently performed three different types of studies on water distribution systems in three very different locations across the country. Inframetrix LLC hired HUSA for a leak survey and fire flow testing program at Lackland Air Force Base in San Antonio, TX. The services included listening, correlating, ground miking and leak pinpointing on 68 miles of mixed metallic and non-metallic, transmission, distribution, and service mains. Fire flow services included multiple hydrant flow sources at twenty residual hydrants.
Another project involved a focused water loss study of the Prichard, AL distribution system for Severn Trent Environmental Services. The Phase I study components included: system supply master meter analysis, distribution system metering analysis, real and apparent loss analysis and 50-miles of distribution system leak survey.
HUSA was contracted by Johnson Controls, Inc. to determine potable water usage for each of the process facilities located within the Patapsco WWTP in Baltimore, MD. The scope of work included accuracy and sizing analysis of plant master meters, flow monitoring at all facilities, water balance development for sources and demands, and field checks and investigation to identify an anomalous demand.
HUSA Speaks at Condition Assessment Seminar
Posted on December 13th 2011
Jeff Griffiths, of HUSA, was invited to speak at the NC AWWA/WEA fall seminar on pipeline condition assessment tools in Wrightsville Beach, NC. A panel of experts discussed a wide range of assessment technologies for gravity, force main and water distribution systems. Jeff spoke about the full array of gravity inspection techniques and technologies, including CCTV, sonar, laser and multi-sensor inspection. The seminar was well attended by 60+ water and sewer engineers, operators and utility system managers.
Multi-Sensor Pipe Inspection Services Published
Posted on October 1th 2011
HUSA’s large diameter multi-sensor pipe inspection services were featured in the October edition of Trenchless World magazine, an international publication for no-dig professionals. The article, which was an was abridged version of a paper presented at the NASTT 2011 No-Dig conference in Washington, DC, was based on HUSA’s inspection of large diameter interceptors in Salt Lake City using the CleanFlow HD Profiler technology.
HUSA Supports Engineers Without Borders
Posted on September 1th 2011
HUSA sponsored a hole for the 5th annual Kleinfelder/ Engineers Without Borders (EWB) Hartford Professional Chapter (HPC) golf tournament at The Ranch Golf Club in Southwick, MA. EWB supports community-driven development programs worldwide by collaborating with local partners to design and implement sustainable engineering projects, while creating transformative experiences and responsible leaders.
Washington Gas Laterals
Posted on August 1th 2011
HUSA recently completed the inspection of approximately 400 sewer laterals in several localities in Northern Virginia. Washington Gas (WGL), which serves 1M+ customers in the MD, VA, DC region, hired HUSA to investigate the potential presence of gas-line cross bores through sanitary sewers.
In Fairfax County alone, WGL has installed approximately 286 miles of 2-inch gas mains by horizontal directional drilling (HDD). Improvements in lateral inspection technologies allowed HUSA to work efficiently and complete the successful pilot project on time.
HUSA at the Misawa Air Base in Japan
Posted on July 15th 2011
Hydromax USA was hired by URS Corporation to perform a leak detection survey on a water distribution system in northern Japan at the Misawa Air Base.
The services included listening, correlating, ground miking and leak pinpointing on 50 miles of mixed metallic and non-metallic, transmission, distribution, and service mains. The work was timely considering the strong earthquake and tsunami that hit the area earlier in 2011.
Dam Inspections in Rockingham County (VA)
Posted on June 15th 2011
Hydromax USA was hired by Gannett Fleming and Hurt & Proffitt to inspect the pipe conduits at the Briery Branch and Hone Quarry dams in Rockingham County, VA. Each engineering firm was selected by the Virginia Department of Conservation and Recreation (DCR) to develop a rehabilitation design.
The dams are considered high hazard dams based on insufficient spillway capacity to meet Virginia’s Dam Safety Regulations. Although the two earth dams are nearly identical, the method of inspection was unique to each due to field conditions.
HUSA performed CCTV inspection of the Briery Branch Dam from the outlet end of the downstream barrel and inspected the Hone Quarry Dam from the 40-foot riser structure in the reservoir.
Fort Meade SSES Services
Posted on May 1th 2011
In September 2009, American Water was awarded a contract for ownership, operation and maintenance of the water and the wastewater systems at Fort Meade Army Base in Odenton, Maryland. With a combined military, civilian, and contractor population of approximately 39,000, it has the fourth largest workforce of Army installations in the continental United States.
American Water hired Bowen Engineering to manage the significant capital upgrade program. Bowen, in turn, hired HDR Engineering for the system-wide sanitary sewer evaluation study (SSES). Hydromax USA (HUSA) was hired by HDR to perform all field services and collect data in support of the SSES study, with a focus on identifying illicit connections and cross connections within the collection system.
The scope of field services included installation and maintenance of 16 flow monitors and four rain gauges for a period of three months. This coincided with smoke testing of approximately 300,000 LF and inspections of over 900 manholes. HUSA also performed 60,000 LF of CCTV inspections, as well as, dye testing and 300 flow isolation tests.
Baltimore County Multi-Sensor Inspections
Posted on April 1th 2011
As a member of ACS Hydrostructures’ team, Hydromax USA performed multi-sensor inspections on sewers 24 inches and greater in diameter in Baltimore County (MD). The scope of the Department of Public Works, Bureau of Utilities project is to provide on-call utility infrastructure condition assessment services.
The multi-year project is part of a plan to comply with the EPA’s Clean Water Act consent decree. Based HUSA’s ability to inspect difficult-to-access sewers and the high quality of report deliverables, much of the inspection assignments were comprised of a 42-inch RCP line that ran through a national park along the Patapsco River, a major tributary of the Chesapeake Bay.
Since the area was in a flood zone, most of the access points were blind flanges that had not been accessed in nearly 30 years. Another challenging field issue was that a lot of the sewer was sandwiched between railroad tracks and the swift-moving river. HUSA overcame this challenge by using a crane to lift all inspection equipment and amphibious vehicles over the river.
There were several 6,000+ LF inspection runs during these work orders. HUSA completed the entire inspection successfully despite the very difficult field conditions.
Lateral Inspections Save Hartford Taxpayers
Posted on February 15th 2011
HUSA inspected nearly 1,200 laterals in support of an I/I study for Hartford Metropolitan District (MDC). All data is being collected and formatted per NASSCO Lateral Assessment Certification Program (LACP) inspection standards.
Hydromax USA was contracted by Kleinfelder/ SEA Consultants to perform this work, which is part of the development of a comprehensive sewer study to address increasing inflow/infiltration (I/I) and a Sanitary Sewer Evaluation Survey (SSES).
After scoring and tallying all inspections, the engineer identified 646 laterals as candidates for replacement. However, the more important figure is the 514 laterals deemed in satisfactory operating condition and not in current need of replacement. The cost to do the lateral inspections was an order of magnitude less than total rehabilitation.
