VEOLIA ENVIRONMENTAL SERVICES ATTAINS ISO 9001:2008
FOR SPECIAL SERVICES, INC.
Certification supports regular quality improvement efforts
LEAGUE CITY, Tex. – Veolia ES Industrial Services, the industrial maintenance and cleaning division of Veolia
Environmental Services North America, is pleased to announce that Special Services, Inc., with corporate offices
and fabrication group based in Neenah, Wisc., has achieved conformance to the ISO 9001:2008 standard for quality
management systems. ISO 9001:2008 conformance was verified by IMSM (member ASQ) via an audit conducted by
one of IMSM’s QAS International auditors.
In Veolia ES Special Services case, an ISO 9001 certification means it has demonstrated a logical and documented
management system for the provision of marine, emergency response, abatement, fabrication and high hazard
services to a range of inland and offshore industries globally. The certification tells Veolia ES Special Services
customers that it has processes in place to control its documents and records, undertake internal quality audits and

The New Infrastructure: Augusta, Ga.,
Sewer Main Replaced with Hobas Pipe
By James A Willson II, P.E., CSI, CCS, Vice President, Augusta Office Regional Manager, Stevenson & Palmer
And Kimberly Paggioli, P.E., V.P. Marketing and Quality Control, Hobas Pipe USA
Augusta, Ga., is about 150 miles east of Atlanta. Established in 1736, ” The Garden City of the South,” has
many local historic attractions that attract visitors from afar and is a hub for military, manufacturing, and
medicine and home of several noted educational institutions. Augusta was named by Relocate-America™ as
one of the “Top 100 Places to Live” in 2009. But none of that kept its aging sewer system from deteriorating.
Federal dollars allocated through the Georgia State Revolving Fund have been awarded to the City of Augusta
to complete reconstruction of a portion of their sewer system with Hobas pipe. The project’s old concrete pipe
was installed in the early 1960s. In 2000, the city engaged Stevenson & Palmer Engineering, Inc.’s Augusta
office to perform a condition assessment of the troubled line. Engineers found that hydrogen sulfide (H2S) and
sulfuric acid (H2SO4) had attacked the crown of the pipe, weakening the structure.
This is a typical occurrence in concrete pipe where you have considerable hydrogen sulfide formation.
Numerous conditions lead to this. The time that sewage remains in the line from the source to the treatment
plant and biological reactions that occur through oxygen depletion are primary contributors. Thiobacillus
bacteria metabolize the hydrogen sulfides, which produce sulfuric acid as a byproduct. The sulfuric acid reacts
with moisture along the exposed pipe sidewalls and attacks the concrete pipe surfaces. Repeated sulfuric acid
attack can deteriorate the concrete pipe leading to exposed rebar and structural concerns.
Stevenson & Palmer was subsequently engaged to design the new gravity sewer for the line with this chemistry
in mind. The recommendation was made to replace almost six miles of the city’s (continued on next page)
