Cleaning Well

A cleaning well, is a well installed in a wastewater or stormwater system to provide access for cleaning, flushing, and maintenance of pipelines. It functions as an access point for jetting hoses, cleaning tools, or inspection cameras, without needing to excavate the ground.

đŸŸ© What Is a Cleaning Well?

A cleaning well is a small chamber installed on wastewater or stormwater pipes that provides:

  • access for cleaning
  • the ability to flush the pipes
  • the ability to perform camera inspections
  • monitoring of flow and levels

It has no sediment trap, and is not designed to collect water — it is strictly for maintenance.

🟩 Why Are Cleaning Wells Used?

✔ 1. To keep pipelines free from blockages

A cleaning well makes it possible to:

  • remove blockages
  • flush away grease, sludge, and deposits
  • clear roots

✔ 2. For inspecting pipe conditions

Inspection cameras can easily be inserted to:

  • detect cracks
  • find root intrusion
  • locate collapsed pipes, settlement, or bad slopes

✔ 3. To avoid future excavation

With cleaning wells in place, you rarely need to dig up the ground for service.

🟧 Where Are Cleaning Wells Installed?

Common applications:

✔ Wastewater (household sewage)

On the service line before the municipal sewer.

✔ Stormwater

To clean pipes carrying roof water and surface runoff.

✔ Drainage systems

To allow flushing and maintenance of drainage pipes.

✔ Long pipe sections

Installed at intervals (typically every 20–50 meters depending on the system).

✔ At changes of direction

Required when pipes turn more than 45°.

đŸ§± How Is a Cleaning Well Constructed?

A cleaning well typically includes:

  • Well chamber (plastic or concrete)
  • Inlet and outlet at the same elevation
  • Straight-through channel — no sump
  • Cover assembly (A15 or B125 depending on location)
  • Telescopic riser for height adjustment
  • Rubber seals for watertight pipe connections

Usual diameters: 110–400 mm.

A cleaning well is a service access point that allows:

  • cleaning
  • flushing
  • camera inspection
  • monitoring of pipelines

It is an essential component for keeping wastewater and stormwater systems functioning properly, and is installed wherever service access is needed.
