Siemens Water Technologies Corp. will install new equipment within the next 120 days to fix a failed $15 million sludge cleanup process at the city’s sewage treatment plant, Chattanooga Mayor Ron Littlefield said today.
Mr. Littlefield said he agreed to hold off on any lawsuit against the contractor after the head of Siemens’ engineering water products agreed last Friday to install a new plate to repair a faulty filter press at the Moccasin Bend Sewage Treatment Plant. If the plate works as designed, Siemens ultimately installed five other such plates to complete a 2001 plan to upgrade the sewer plant.
They initially wanted another year and a half to install their new plate, but I said we would give them 120 days to see if their new plate design worked, Mr. Littlefield said.
If it doesn’t, Mr. Littlefield said a rival firm has offered to fix the failing filter presses.
The city contracted in 2001 with US Filter Corp., later acquired by Siemens, and the engineering firm of Consolidated Technologies to build a filter press to clean up and condense sludge produced at the sewage plant. A recent city audit found that Chattanooga had spent more than $15 million on the system that has yet to work as designed.
