The three-bucket system is a cleaning procedure used in hospitals and other healthcare facilities to ensure thorough cleaning while reducing the risk of cross-contamination. It involves using three separate containers or buckets, each with a distinct purpose in the cleaning process. This system helps improve efficiency and ensures that disinfectants and cleaning solutions are properly used, reducing the chance of spreading pathogens from one surface to another.

Here’s how the three-bucket system works…

Dirty Water Bucket (Soiled Water)

• Purpose – This bucket is used for dirty water that has been used to clean surfaces, especially after mopping or cleaning floors. It collects the water mixed with dirt, dust, and other contaminants that were removed from the surfaces.
• Tasks
  • After each cleaning pass, the dirty mop is rinsed in this bucket.
  • This prevents dirt from being spread around when the mop is used again on clean areas.
  • The dirty water should be disposed of regularly and not reused.

Clean Water Bucket

• Purpose – This bucket contains clean water (often mixed with a cleaning solution or detergent) to be used for washing and scrubbing surfaces.
• Tasks
  • The mop or cleaning cloth is dipped into this bucket to pick up a cleaning solution for the next cleaning pass.
  • It’s important to frequently change the water to maintain the cleanliness of the surfaces being cleaned.
  • The clean water bucket ensures that surfaces are being cleaned with fresh, non-contaminated liquid.

Disinfectant Bucket (Sanitizing Solution)

• Purpose – This bucket holds a disinfecting solution, which is used to sanitize surfaces after they have been cleaned with water and detergent.
• Tasks 
  • The disinfectant solution is applied to high-touch or high-risk areas, such as bathrooms, patient rooms, and medical equipment.
  • After cleaning with water, the surfaces are disinfected with the solution to kill germs, bacteria, and viruses.
  • This bucket should contain the correct concentration of the disinfectant to ensure it’s effective at killing pathogens.

How the Three-Bucket System Works Together

• Step 1 – Cleaning – First, the cleaning cloth or mop is dipped into the clean water bucket, and used to clean the surfaces, removing visible dirt, dust, and grime.
• Step 2 – Rinsing – After cleaning a section, the mop or cloth is rinsed out in the dirty water bucket to remove contaminants picked up during the cleaning process.
• Step 3 – Disinfecting – Finally, the cleaned surface is disinfected using a solution from the disinfectant bucket. The mop or cloth is dipped into the disinfectant and applied to the surfaces, ensuring that pathogens are killed before finishing the cleaning task.

Advantages of the Three-Bucket System

• Reduces Cross-Contamination – By separating clean, dirty, and disinfectant solutions, the system prevents contaminants from being spread to other surfaces, ensuring a more effective and hygienic cleaning process.
• Increases Efficiency – The three-bucket system ensures that each stage of cleaning (washing, rinsing, and disinfecting) is done in a structured manner, minimizing the risk of mistakes and contamination.
• Improved Infection Control – By disinfecting surfaces after they are cleaned, hospitals can effectively reduce the spread of infections, ensuring a safer environment for patients, staff, and visitors.
• Cost-Effective – It minimizes the need for excessive cleaning products and helps ensure that disinfectants are being used properly without waste.

The three-bucket system is a simple yet highly effective method in hospital cleaning that helps separate the processes of cleaning, rinsing, and disinfecting. It promotes better hygiene practices, reduces cross-contamination, and helps maintain a safe, sterile environment for patients and healthcare workers. This system is particularly important in high-risk areas, such as ICUs, patient rooms, and surgical areas, where infection control is critical.
