Pipe Cleaning and Disinfection

Disinfected piping, safe water from day one

New drinking-water piping picks up dirt, welding residue, and bacteria during installation, and it must be disinfected before drinking water is introduced. A contractor seeking Form 4 and building occupancy is required to present a pipe disinfection certificate. Kesar Digum performs the disinfection with approved agents, takes a verification sample tested at an accredited laboratory, and issues the disinfection certificate - so the system is ready for occupancy and the water is safe from the very first moment.

Disinfection Certificate for Form 4

Issuing a pipe disinfection certificate based on the sampling results - the document required to obtain Form 4 and occupy the building.

Regulation

When Is Pipe Disinfection Required?

Pipe disinfection and a disinfection certificate are required in several situations. These are the most common:

Ahead of Form 4

A contractor who needs Form 4 to occupy a building must present a drinking-water pipe disinfection certificate as a condition for receiving it.

Before occupancy

New Building

Every new drinking-water piping system must be disinfected before water is put into use, to ensure water quality from day one.

On completion of construction

Renovation and Pipe Replacement

Renovating a water system or replacing sections of piping calls for disinfection and verification sampling before returning to service.

As needed

New Connection to the Network

Connecting a new internal line to the water network requires flushing and disinfection, so it doesn't introduce contamination into the existing system.

As needed
The Risk

What Happens Without Pipe Disinfection?

New piping that hasn't been disinfected carries contamination straight into the drinking water. Here's what's at stake:

Drinking-Water Contamination

Dirt, installation residue, and bacteria left in new piping pass straight into the water that reaches the tap.

Delay in Receiving Form 4

Without a pipe disinfection certificate, the process with the authority can't be completed, and occupancy is put off until disinfection is done.

The Contractor's Liability

The contractor is responsible for the drinking-water quality in the building they hand over, and un-disinfected piping exposes them to defects and claims.
