Water Resource monitoring

   
Identifying-a-new-source-of-water_1

New water resource sites are intensively investigated and monitored prior to becoming a Nestlé Waters source.

Nestlé Waters is implementing a series of checkouts to ensure the permanent quality of water.

That is why Nestlé Waters has developed a monitoring system of physical parameters for all catchments based on withdrawals, level, flow, conductivity, temperature, and rainfall.

Constant interpretation of data is critical in order to immediately detect any abnormality and anticipate long-term trends.

It allows us to implement immediate action including temporarily reducing or stopping bottled water production.

The ability to react quickly is essential if we are to avoid deviations that may lead to a major intervention on the catchment, a temporary decrease of water supply or even the permanent loss of a resource for our bottling activities.

Here is a summary page of a typical monthly report for Nestlé Waters’ catchments around the world :

Environmental monitoring extends beyond the immediate locality of our water sources to include the whole water recharge area.

In partnership with local communities, we work to ensure that only as much water is taken from an aquifer as its replenishment capacity allows.

This review is monitoring 7 parameters to preserve the future of the source :


1) Identity card of the catchment : name, factory, brand, altitude.


2) Technical information identifying :

  • daily and monthly licenses for withdrawal pump position
  • minimal dynamic water level

3) Daily and cumulative water withdrawals.


4) Daily average of continuous measurement of the catchment’s physical characteristics

  • flow
  • pressure at the wellhead
  • dynamic and static water levels
  • conductivity,
  • temperature, flora

5) Daily weather indicators
    • temperature,
    • rainfall

6) Graphic representation of data 3 + 4 + 5. For highlighting historical trends, same graphs are also consolidated on a longer timescale : yearly, five years, etc.

7) Samples collected for NWQAC for analysis and comment.

Water resource qualitative monitoring

Quality monitoring is implemented at all stages of the production process from the water source to the filling machines, to water transportation in pipes and storage tanks.

Consistency of the original characteristics of mineral water and to some extent for spring water is part of the regulatory specifications which dictate that treatments are not allowed to correct abnormalities.

Even though the original quality of water is much less critical for purified water, samples are taken directly from the source to perform complete analysis on a regular basis. Thus, our waters are continuously controlled to ensure their full compliance with the respective regulatory framework as well as our internal quality standards.
