Problem: A private retirement facility in Sumter County, Florida, with more than 100,000 residents, has an expansive network of stormwater infrastructure to accommodate expansion. A 60-inch stormwater line had a large deposit of sand, blocking flow of water 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, the peak month of Florida’s seasonal residents and activities.

Solution: Polston Applied Technologies brought its PAT 949 Combination3 truck to the site and extended the jetter from the outlet to the sand plug. Using the waterjetting system and sand and grit removal process, the crew was able to jet the sand downstream to the downhole pump for removal. The sand and grit was filtered into a containment tank, then hauled away. Water used in the process was returned to the stormwater line.

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