Private Sewers Rehabilitation Programme

Overview

The private sewers are owned by the private premises' owners. These owners are responsible for maintaining the private sewers.

Used water from private premises such as condominiums, commercial buildings and shophouses is sent to public sewers through the private sewer network.

How You Can Help
1. Check your private sewers regularly

You can engage a contractor to check if your private sewers are leak-free and properly connected to the public sewer. This can be done by carrying out a leak test or other means. 

2. Repair any leaks
You should carry out the necessary repairs if any leaks are found in your private sewers.  You can engage a contractor or contact PUB for assistance. 

Private Sewers Rehabilitation Programme
  • Under the Private Sewers Rehabilitation Programme, PUB conducts, checks and assists in the investigation and inspection of the private sewers of private premises (condominiums, commercial buildings, factories, etc.) in Jurong Lake Catchment.



  • Outreach ProgrammeTo help premises owners to ensure that their private sewers are functioning properly, PUB has embarked on a four-stage outreach programme. For more information, click here [PDF].
  • The government also provides the following assistance to premise owners whose private sewers are found to be defective:
    • Technical assistance
    • List of contractors who are able to carry the work
  • Subsidy for the Rehabilitation Cost

    The subsidy is based on the proportion of length of private sewers outside the premises or 5% of the total repair cost, whichever is higher.
  • The illustration below shows how the subsidy is calculated

In the illustration, the total length of private sewer is 10m and the length outside the property boundary is 2m. Therefore:

Percentage of Rehabilitation Cost borne by Government = 2/10 x 100% = 20%

Percentage of Rehabilitation Cost borne by Owner = 8/10 x 100% = 80%

If the proportion of the private sewer outside the boundary is found to be less than 5%, the government will bear 5% of the rehabilitation cost.
