Disinfection for Form 4

A disinfection certificate that moves occupancy forward

Form 4 is the completion certificate that allows a building to be occupied and permanently connected to infrastructure. One of the conditions for obtaining it is presenting a disinfection certificate for the drinking water piping - proof that the water reaching the residents is safe to use. During construction, new piping collects dirt, installation residue, and bacteria, which is why it must be disinfected before occupancy. Kesar Digum performs the disinfection with approved agents, takes a verification sample at an accredited laboratory, and issues the required disinfection certificate - so the building is ready for occupancy and the Form 4 process moves ahead without delays.

The risk

What happens without a disinfection certificate?

Without a valid disinfection certificate, occupancy is halted and the water in the piping is not safe. Here is what is at stake:

Delay in obtaining Form 4

Without a pipe disinfection certificate, the process with the authority cannot be completed, and occupancy is postponed until the disinfection and sampling are done.

Drinking water contamination

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

Contractor and developer liability

The contractor and developer are responsible for the drinking water quality in the building they hand over, and piping that was not disinfected exposes them to deficiencies and lawsuits.
