Water Sampling and Testing for Residential Buildings and Building Committees

The building's shared water system - the storage reservoirs, the main piping and the central hot water heater - is the building committee's responsibility. Neglecting it can contaminate the drinking water of every resident. Periodic sampling and disinfection keep the building healthy.

Residential Buildings - Sampling That Protects What Matters

Many buildings are fitted with storage reservoirs from which water is pumped to the apartments. Over time, sediment, rust and bacteria build up in the reservoir, and Legionella can develop in the central hot water heater. Because this is a shared system, contamination at a single point reaches the tap of every resident - children, the elderly and healthy adults alike.

Kesar Digum helps building committees and management companies keep the water system sound: testing reservoirs and drinking water, periodically cleaning and disinfecting the reservoir and piping, and monitoring Legionella in central hot water systems - with an orderly report for all apartment owners.

Sampling and Testing Types

What We Sample in Residential Buildings

The core tests we perform for this sector - by type of water, food and risk.

Water Reservoir Testing

Sampling storage reservoirs to detect sediment, bacteria and contamination, with a recommendation on cleaning and disinfection frequency.

Full Details

Drinking Water Sampling

Testing for coliforms, E. coli and chemical parameters in the building's shared drinking water.

Full Details

Cleaning and Disinfection of Reservoirs and Piping

Professional cleaning and disinfection for the reservoir and main piping, with follow-up sampling to confirm the system is sound.

Full Details

Legionella Monitoring in Hot Water

Legionella testing in central hot water heaters, especially relevant in buildings with older residents.

Regulation

When Is Sampling Required?

Responsibility for the shared water system places clear monitoring obligations on the committee. These are the situations that call for sampling and treatment:

Cleaning and Disinfecting Water Reservoirs

Storage reservoirs in the building require periodic cleaning and disinfection, along with a water test to confirm they are sound after treatment.

Annually

Sound Shared Drinking Water

The water supplied to residents must meet the drinking water quality requirements of the Public Health Regulations.

Periodic

After a Fault, Burst or Repair Work

A pipe burst, plumbing work or resuming supply after a shutoff all require disinfection and sampling before the water is used again.

Per Event

Central Hot Water Systems

In buildings with a central hot water heater, and especially with an older population, periodic Legionella monitoring is recommended.

The Risk

What Happens If You Skip Sampling?

When the system is shared, a single failure touches every resident - and it falls on the committee. Here's what's at stake:

Contaminated Drinking Water for the Whole Building

A contaminated reservoir or piping reaches the tap of every apartment, exposing all residents to waterborne illness.

Danger to Children and the Elderly

Children, pregnant women and the elderly are especially vulnerable to drinking water contamination and to Legionella in the hot water system.

Legal Liability for the Committee

The building committee is responsible for the integrity of the shared system, and a maintenance failure can expose it to claims from residents.
