Mission Main is the major sewer treatment plant in Johnson City, KS. Sections of 24” and 30” sewer lines that ran parallel to each other and shared a common manhole were in need of repair. New sewer pipe had been purchased for replacement but there were problems with the curing of the protective epoxy coating. The coating was peeling off and needed to be re-applied. However, excavation had already commenced to replace the old sewer lines with the new, faulty sewer line.
The 24” sewer line was only 4’ from the surface and did not have any storage – the amount of room available in the sewer line. The combination of the shallowness of the sewer line along with the high peak flows was causing surcharging. Surcharging occurs when the sewage becomes too much for the pipe to hold and exits from the manhole and flows out into the environment. The surcharge was flowing at about 5,400-gallons per minute at peak flows.
David Belcher, project manager of Wilson Plumbing Company contacted Thompson Pump’s Kansas City Branch for assistance with the bypass.
After visiting the site and determining what was required to prevent the threat of surcharging and eventually allowing the repairs to be made, the Kansas City Branch representative recommended using two Thompson 12-inch solids handling high pressure pumps with the Silent Knight® sound attenuated canopy as the primary bypass pumps. The Thompson 12-inch solids handling high pressure pumps are capable of maximum capacities of up to 5,250 gallons per minute each and are equipped with the Enviroprime System® which provides quick priming and re-priming times and protects the environment against sewage and other environmentally-hazardous materials from escaping the priming system. The two 12-inch pumps were used to counteract the massive amounts of sewage experienced during peak flows and to prevent surcharging. The pumps discharged through 12” High-Density Polyethylene (HDPE) Pipe and into a common manifold regulated by 12” gate valves. From there, 500’ of 18” HDPE Pipe was run to an open 24” manhole away from the repair area where it was discharged. One Thompson 6-inch dry prime trash pump with the Enviroprime System® was also used for standby.
Even with the high flows from the Thompson 12-inch solids handling high pressure pumps, the surcharge of the sewage was exiting from the sewer line quicker than the pumps could re-prime after depleting the line of sewage. The Thompson compressor-assisted Enviroprime System® has some of the quickest priming times in the industry, but the sewage was surcharging out of the sewer line faster than the quickest priming times could counteract.
In order to combat this situation, another 6-inch dry prime trash pump with the Enviroprime System® was strategically placed at the available manholes before the main bypass. This was to further prevent the surcharging and direct flows of up to 1,500 gallons per minute into the 30” line that was slightly deeper and had adequate storage capacity.
Once the surcharging emergency was rectified, and the epoxy was re-applied to the new sewer pipe, the line was successfully repaired.
The Pied Creek Treatment Plant, in Kansas City, MO, was being refurbished into a new Pump Station. The treatment plant employed submersible pumps to move the raw sewage, but the submersible’s discharge piping had become corroded and was not directing the sewage properly. Francis Reddy, engineer for Pollution Control, contacted Thompson Pump based upon a previous successful project Thompson Pump worked on with Foley Company, the contractor in charge of the rehabilitation of the pump station.
Mr. Reddy was concerned because the pumps would have to discharge about 150’ away from the pumping site, and into a force main, which could produce as much as 60-psi of backpressure, or “water hammer,” on the pumps. Water hammer occurs when pressure in either the suction or discharge sides of the pump system, is high enough to cause the effluent to stop quickly and “hammers” back into the pump. This hammer-effect could cause severe damage to the pump, and cause the suction or discharge hose or pipe to react violently to the pressure causing it to break, tear, or even become loose from its connection to the pump.
The peak flows of the Pied Creek Treatment Plant were as much as 3,500 gallons per minute. Thompson Pump’s Kansas City representative reviewed the project with Mr. Reddy and proposed using a Thompson Pump 6-inch solids handling compressor-assisted high pressure pump with the Enviroprime System® for the primary pumping. A 12-inch solids handling compressor-assisted high pressure pump with the Enviroprime System® and with an automatic start and stop control panel with flotation device was recommended for back-up duty. Because these pumps were equipped with diesel engines, the speed of the pump could be accelerated gradually, which would help protect the system against the backpressure from the force main.
Each of the pumps were equipped with Thompson Pump’s exclusive Enviroprime System®, which has been proven to be a valuable addition to any bypass application. By design, the Enviroprime System® prevents the pumping effluent, in this case, sewage, from escaping from the priming system and causing an environmental concern. It also is able to prime and re-prime quickly, even in “snore” conditions (when a pump’s suction strainer is no longer submersed in the water and pulling is in air).
The Thompson pumps with all of the necessary connections were supplied to the Pied Creek plant and Thompson Pump also supplied and fused 200’ of High Density Polyethylene (HDPE) pipe for the bypass. The HDPE pipe specifically selected due to the risk of water hammer because it is heavier, more rigid pipe. Because HDPE pipe is tougher, any bracing of the discharge hoses was not required. Also, HDPE pipe is fused, rather than connected, which therefore eliminated the chance of connections leaking or breaking and causing an environmentally hazardous situation. The two pump’s discharges were connected to a common manifold with gate valves to help regulate the flow, and then were discharged into the force main. With the Thompson Pumps in place, “the bypassing worked flawlessly,” reported Mr. Reddy.
