5 Reasons to Get a Sewage Grinder for Your Property

By In Blog On July 29, 2020

A sewage grinder is a specialized piece of pump equipment that processes sewage and wastewater. After water leaves your property, it flows downhill and is contained in a holding tank. Once that tank reaches a certain capacity, the sewage grinder activates, grinding up larger wastewater solids into smaller particles. These particles move easier through sewer lines.

But why would you need this high-powered grinder for your property? Sewage grinders are good at delivering sewage at a high pressure and speed in smaller amounts. Here are five of the reasons you may need one for your property.

1. Your Property’s Elevation Is Low

One of the main benefits of a sewage grinder pump is that it uses pressure to lift wastewater and sewage to a higher elevation. Most sewer systems take advantage of gravity, and the wastewater naturally flows downhill through the pipes to the septic tank or city sewer line. However, if your property is at a lower elevation than the nearest sewer line, gravity will not be able to help you.

If you need to lift your wastewater to a higher elevation, then a sewage grinder pump may be the best choice for you, especially if the sewage needs to be lifted 30 feet or more. Not only do sewage grinders crush waste solids into smaller pieces that are easier to move, but they also generate enough pressure to push the sewage upward. This allows your wastewater to be elevated enough to reach the sewer line.

2. The City Main Is Pressurized

If your municipal sewer main is pressurized, then unpressurized wastewater will not be able to enter. The pressure differences will block your sewage from entering the main.

The only thing that can overcome a pressurized difference like this is a pressurized pump. A sewage grinder pump serves this purpose, as the same pressure that allows the pump to move waste upward can push the sewage into a pressurized main.

3. The Sewage Must Travel a Long Distance

Sewage grinder pumps usually handle a lower amount of sewage, less than 30 gallons a minute, but they can push it much longer distances than other pumps because they grind down heavier solids.

What this means is that sewage grinders are especially good for pumps that need to push wastewater at least 750 feet or more. If your waste has a long way to go, consider getting a sewage grinder.

4. Your Business Produces a Lots of Wastewater

Certain businesses, like restaurants, are required to have a sewage pump in some areas, regardless of where they are located or how far their waste needs to be pumped. This is because they often produce more wastewater with solid wastes and need to grind down these waste solids before they enter the main line.

However, even though a sewage grinder can handle many solids, remember to avoid putting certain things in sinks and drains, as they can still clog up your plumbing lines. Throw away cooking fats and oils, degreasing solvents, sanitary napkins and tampons, strong chemical substances, glass, metal, plastic, hair, and ashes instead of flushing or dumping them down drains.

5. You Don’t Use a Septic Tank

Sewage grinder pumps work best for properties that don’t have a septic tank. If you have a septic tank, then a sewage grinder can ruin the subsurface leaching field. A leaching field is a special subsurface facility where impurities are removed from the wastewater so the water can be purified and recirculated. However, sewage grinders turn the wastewater into a fine slurry where solids and liquids mix together and remain in a mixed state.

In this state, the solids cannot be filtered or removed from the wastewater, so the water can’t pass to a secondary system. The leaching field is there to let the water eventually disperse and return to the water cycle, but it can’t do this if the water and contaminants are thoroughly mixed. Because of this, sewage grinder pumps are best for systems that do not use a septic tank.
