The wastewater is removed from our homes and businesses using 6” clay/plastic pipes that convey liquid and solids to the main sewage pipe that runs under the middle of the road toward the wastewater treatment plant. The pipes run at an angle to assist the gravitational flow, with this being boosted on its way by pump stations. The pipes also collect runoff from hard standing features such as car-parks and drainage from the roads, which contains tar, hydrocarbons, salt, and grit.
