Project Scope
This project had 3 steel reservoir tanks built from 1950 to 1970 that were responsible for holding 15 million gallons of potable water. That water was then dispersed to Dekalb County for customer use. In 2018, the 2nd reservoir tank’s roof started to collapse in on itself. Scott Candler Water Treatment Facility (SCWTF) set out to rebuild these old tanks and extend their lifespan. The tanks would have their coatings stripped, any damage discovered would be repaired, and the old roofs on tank 2 and 3 would be removed and replaced. The coatings would then be replaced both inside and outside to prevent any future rusting on the tank.
SCWTF’s high-speed distribution pump station also required the removal of several sections of corroded steel pipe, valves, and fittings. The walls of the steel pipes were checked for thickness and found to be significantly thinner than designed. A failure of this line would very likely cause a disruption of service for County residents. Hundreds of feet of 54” buried pipe and pipe housed within the pump station were replaced and coated.
Lastly, SCWTF requested the removal of 4 small pumps at their transfer station to be replaced with 2 larger more efficient pumps that would work together with 8 existing pumps. The 2 new pumps are powered by new variable frequency drives to lessen the stress on the pre-existing pumps.
