Low-Pressure Sewer System Installation & Repair
Serving Kansas City & Surrounding Areas
Not all sewer systems are created equal. Some homes and neighborhoods—especially in Wyandotte County and parts of Kansas City, KS—rely on low-pressure sewer systems to move wastewater to the main sewer line. These systems require special equipment, electrical connections, and a trained contractor to install and maintain them properly.
At Apex Underground, we specialize in outdoor grinder pump systems, including installation, replacement, and troubleshooting for residential and commercial properties. We’re one of the few contractors serving the greater KCK area with experience in the outdoor grinder pump systems, 2-inch pressurized lines, and electrical hook-ups required for low-pressure sewer systems.
Specialized Sewer Solutions for Properties That Need More Than Gravity
What Is a Low-Pressure Sewer System?
Low-pressure sewer systems are used in areas where gravity flow isn’t possible—usually because of elevation changes, rock bed, or long distances to a municipal line. Instead of relying on slope, these systems use a grinder pump installed underground (typically 8–10 feet deep) to push wastewater through a small-diameter pipe—often 2 inches wide—all the way to the city sewer connection. 
This type of system is often used when:
- Your property sits below the street level
- There's flat or uneven terrain preventing proper drainage
- You're in a remote or rural area with no conventional sewer access
- The area has strict space or slope constraints
Each system includes:

- A grinder pump basin (installed underground)
- 2” pressure-rated sewer line
- Electrical hook-up to power the pump
- Backflow prevention and system alarms
Why Low Pressure Sewer Systems Require a Specialist
Higher Requirements, Higher Expertise
Low-pressure sewer systems aren’t standard—and
not every contractor is equipped to install or service them. At Apex Underground, we understand the unique permitting, design, and installation requirements these systems demand—and we’ve completed projects where others couldn’t.
Electrical hookups to power the grinder pump
Specialized connections to tie into 2" pressurized lines
Deep excavation, often up to 9 feet
Compliance with municipal standards

What to Know (and Why It’s Smart to Hire the Right Crew)
When the City Requires a Low-Pressure Sewer System
In some areas, like Lee’s Summit, MO and Gardner, KS, the city mandates a low-pressure sewer system due to the layout of the municipal sewer infrastructure. If you’re building or updating a home in one of these zones, you won’t have a choice between gravity or pressure—a grinder pump system will be required to connect.
So what does that mean for you?
It means your property will need:
- A buried grinder pump station, typically 8–10 feet deep
- Proper trenching for 2” pressurized sewer lines
- Electrical connections to power the pump system
- Specialized fittings, backflow prevention, and inspections
Most plumbing contractors don’t handle these systems—especially the excavation, pressure line work, and coordination with utility companies. That’s where Apex Underground comes in.
We Know the System—and the Cities That Use It
We’ve installed dozens of city-mandated systems and know the ins and outs of:
- Permitting and pressure-sewer regulations in Wyandotte County, Jackson County, and beyond
- Trenching for tight lots, challenging grades, or existing utilities
- Handling the electrical component and final tie-in
- Working directly with inspectors to make sure everything passes the first time
If you’ve been told you need (or have) a low-pressure sewer system, we’ll take it from there—and make sure the job gets done cleanly, safely, and to code. Call now to learn more about your low-pressure sewer system today.
