Requirements on water supply systems

Drinking water is one of our most important elements and is accordingly subjected to very strict regulations. It is obliged to follow national guidelines on drinking water. The guidelines mentioned in our Specification Manual are based on the regulation in Germany and the European Union.

Directives on the quality of water intended for human consumption
- Germany:3 Trinkwasserverordnung TrinkwV2001
- European Union: Drinking Water Directive 98/83/EC (see below)

In Germany the relevant requirements on drinking water and technical requirements on drinking water systems are based on long term practical experience and laid down in codes of practice. These general accepted codes of practice are a combination of laws, standards and guidelines to ensure:
- Hygienic reliable drinking water
- Long term undisrupted system use
- Avoid nuisance like noise
- Prevention loss of waste and energy

Drinking Water Directive

Drinking Water
High quality, safe and sufficient drinking water is essential for our daily life, for drinking and food preparation. We also use it for many other purposes, such as washing, cleaning, hygiene or watering our plants. The European Union has a history of over 30 years of drinking water policy. This policy ensures that water intended for human consumption can be consumed safely on a life-long basis, and this represents a high level of health protection. The main pillars of the policy are to:
- Ensure that drinking water quality is controlled through standards based on the latest scientific evidence.
- Secure an efficient and effective monitoring, assessment and enforcement of drinking water quality.

The Directive overview
The Drinking Water Directive concerns the quality of water intended for human consumption. Its objective is to protect human health from adverse effects of any contamination of water intended for human consumption by ensuring that it is wholesome and clean.

The Directive laid down the essential quality standards at EU level. A total of 48 microbiological, chemical and indicator parameters must be monitored and tested regularly. In general, World Health Organization's guidelines for drinking water and the opinion of the Commission's Scientific Advisory Committee are used as the scientific basis for the quality standards in the drinking water.

National Legislation
When translating the Drinking Water Directive into their own national legislation, Member States of the European Union can include additional requirements e.g. regulate additional substances that are relevant within their territory or set higher standards. Member States are not allowed, nevertheless, to set lower standards as the level of protection of human health should be the same within the whole European Union.
