Long before the apple first fell on Sir Isaac Newton’s head, waste has been flowing downhill. In many cases it still does. But as populations branched out to lower elevations, gravity no longer could do the job, and lift stations were needed to restore flow.Today, not all waste flows downhill. The law of gravity hasn’t reversed, but technology — specifically low-pressure sewer systems — enable municipal waste to go where no waste has gone before: over undulating bedrock, through wetlands and across vast rural regions. It does this by using a grinder pump that turns solids into slurry that can
The Sewer Battle: Gravity vs. Pressurized
Gravity and low-pressure sewer systems both have benefits, but apples to apples, low-pressure systems cost less to install.
