Steep plots and long rising mains
On hilly ground a pump may have to push sewage a long way uphill through a rising main. That puts more strain on the motor than a flat site would, and any rags or fat in the wet well make it worse. For stations like these, a regular service matters more than usual.
Wet woodland and clay soils can also let groundwater seep into older chambers. If your station seems to run almost constantly, that may be why, and it’s worth having it looked at before the pumps wear out.
