One way is to use naturally absorbent products or chemical-based soil cleaning products.
The presence of fat and the risk of slipping is particularly high in certain types of work.
Product examples: DINOSORB, SIDABSORB from SID
Others you might try: clay soil and sodium bicarbonate.
Warning: an absorbent is coded according to the waste product it is used on. You must eliminate it according to current guidelines for that product.
Beware of products that dissolve grease in the water. Later it is difficult to eliminate the fats during wastewater pretreatment, so they have their share of drawbacks…
If you are able to control your drawdown range, you can alternate water levels in the station and thereby prevent fat from always being deposited in the same places.
E.g,: set two drawdown levels, one at 2 m and one at 2.15, and the pumps will run a cycle on each. .
If you don’t have an analog measuring device in place, you could use a piezometric sensor.
This is what I was going to suggest.
Some level controller allow you to program a hysteresis that will randomly change the level setpoint at which to start and stop the pumps.
Pollution prevention is your most cost efficient and sustainable method to protect our sewer system infrastructure!
