What is a Sewage Sump Pump?

A sewage sump pump is a submersible pump installed in a collection pit (sump) that automatically activates when wastewater reaches a predetermined level. The pump lifts sewage from below-grade areas — basements, underground parking, building service areas — up to the municipal sewer line or septic system.

Unlike standard sump pumps that handle groundwater, sewage sump pumps are specifically designed to handle:

Raw sewage with solid waste
Toilet paper and sanitary waste
Greywater from sinks, showers, and laundry
Grease and food particles from kitchen drains
Sand, grit, and debris from floor drains

Our Installation Process

1. Assessment & Design

We evaluate your site's sewage volume, vertical lift required, pipe diameter, and electrical supply. Based on this, we design the optimal sump and pump system with proper redundancy and alarm systems.

2. Sump Construction

We design or modify the sump pit with proper dimensions, inlet/outlet connections, vent pipe, and access cover. The sump is sealed to prevent odor leakage and groundwater contamination.

3. Pump Installation

The Flow Chem submersible sewage pump is installed on guide rails or a discharge connection. We ensure proper sealing, anti-vibration mounting, and corrosion-resistant hardware for long service life.

4. Float Switch & Controls

Float switches or level sensors are calibrated for automatic start/stop. We install high-water alarms, indicator lights, and manual override switches. Control panels are mounted in accessible locations.

5. Discharge Piping

We install the discharge pipe with proper check valves, gate valves, and cleanouts. Piping is sized to prevent clogging and ensure adequate flow velocity for solids transport.

6. Testing & Commissioning

Full operational testing including automatic cycling, alarm verification, and performance measurement. We simulate high-water conditions to verify alarm response and backup pump activation (duplex systems).

Types of Sump Pump Installations

Simplex System (Single Pump)

Ideal for residential basements, single-bathroom additions, and small commercial spaces. One pump handles normal flow with a high-water alarm for overflow protection. Cost-effective and reliable for moderate sewage volumes.

Duplex System (Dual Pump — Recommended for Commercial)

Two pumps installed in the same sump with alternating duty. If one pump fails or flow exceeds capacity, the second pump activates automatically. Essential for commercial buildings, hospitals, hotels, and any facility where pump failure is unacceptable.

Alternating duty extends pump life (each pump runs 50% of the time)
Automatic backup — no manual intervention needed
High-flow mode activates both pumps simultaneously during peak loads
Individual pump isolation for maintenance without system shutdown

Triplex System (Triple Pump — Industrial)

Three pumps for high-capacity industrial and municipal applications. Provides N+1 redundancy — the system maintains full capacity even if one pump is offline for maintenance. Used in large STP facilities, industrial complexes, and high-rise buildings.

Frequently Asked Questions

How does a sewage sump pump differ from a regular sump pump?

A regular sump pump handles groundwater (relatively clean water). A sewage sump pump is designed to handle raw sewage containing solid waste, toilet paper, and organic matter. Sewage sump pumps have larger impeller clearances, stronger motors, and specialized seals to prevent clogging and corrosion from sewage.

Do I need a simplex or duplex system?

For residential applications (1-2 fixtures), a simplex system is usually sufficient. For commercial buildings, hospitals, hotels, or any facility where pump failure could cause sewage backup, we strongly recommend a duplex system. The redundancy ensures continuous operation even during pump maintenance or failure.

What maintenance does a sewage sump pump need?

We recommend quarterly inspection of float switches, annual pump removal for cleaning and seal inspection, and testing of alarm systems every 6 months. Flow Chem offers annual maintenance contracts that cover all routine maintenance tasks and emergency breakdown service.

Can a sewage sump pump handle toilet waste?

Yes. Flow Chem sewage sump pumps are specifically designed to handle raw sewage including toilet waste, toilet paper, and sanitary products. Our vortex impeller design passes solids up to 60mm without clogging, making them ideal for basement bathroom installations.

What happens during a power outage?

Standard pumps require electricity to operate. We recommend installing a backup power supply (generator or inverter) for critical installations. For commercial and industrial applications, we can integrate UPS systems or specify pumps compatible with backup generators for uninterrupted sewage management.
