A Pumping Chamber is a vital structure used in plumbing, drainage, and water supply systems to collect and pump wastewater, stormwater, or treated water from low-level areas to the main drainage line.
This drawing provides a detailed AutoCAD DWG showing Pumping Chamber Details, including plan, section, pipe connections, valves, and pump arrangement.
It is ideal for civil, plumbing, and MEP engineers designing water supply or drainage infrastructure.
What Is a Pumping Chamber?
A pumping chamber (also known as a sump or wet well) houses one or more pumps that lift water to a higher elevation.
It is commonly used when gravity flow is not possible, such as in basements, underground car parks, and sewage networks.
Typical applications include:
- Stormwater and sewage lifting stations
- Building basement sump systems
- Water treatment plants
- Irrigation and pressure boosting systems
Key Components in Pumping Chamber Details
| No. | Component | Description |
|---|---|---|
| 1 | Concrete Chamber | Reinforced structure designed to resist water pressure and soil load |
| 2 | Submersible Pumps | Transfer wastewater or stormwater to higher level |
| 3 | Non-Return Valve (NRV) | Prevents backflow when pump stops |
| 4 | Gate / Isolation Valve | Allows maintenance or isolation of discharge line |
| 5 | Float Switch or Level Sensor | Automatically starts/stops pumps based on liquid level |
| 6 | Access Cover & Ladder | Provides maintenance entry for operators |
| 7 | Vent Pipe | Releases trapped gases and odors |
| 8 | Discharge Pipe & Manifold | Carries pumped water to main drainage line |
