I have an 8" HDPE raw sewage pressure main 13,000' long running uphill a total of 110'at almost a constant slope with a few 5' dips in elevation (under culverts, etc.). What flowrate must be maintained to prevent settlement of sludge from plugging the pipeline over time(scouring)? Currently the pumps only run a few hours per day until future housing developments tie in (years from now) and I'm insisting they run long enough each time to totally flush the line plus 10-15% more. Do I have a problem or not? Thanks
