Combination truck cleans stormwater pipe

Problem: A nearly 100,000-resident private retirement facility in Sumter County, Florida, with an expansive network of stormwater infrastructure had a 60-foot stormwater line with a large deposit of sand blocking flow inside the pipe. The blockage was 375 feet from the closest access point on the street, and the pipe was in the middle of a residential neighborhood. The work needed to be performed in December, at the peak of Florida’s seasonal residence.   

Solution: Polston Applied Technologies employed a PAT 949 combination truck and was able to extend its jetter from the outlet to the sand plug 375 feet away. Using the powerful waterjetting system and grit and sand removal process, the crew was able to jet the sand downstream to the downhole pump for removal. The sand and grit was then filtered into a containment tank and hauled away for disposal. Water used in the process was returned to the stormwater line.

Result: The sand deposit was completely removed, flow to the stormwater line was fully restored and the work was accomplished in two days. Due to the quiet operation, the project had almost no impact on daily neighborhood activities. 844/765-7866; www.polstonprocess.com.
