Drinking Water Hygiene / Drinking Water Sampling

Product catalog summary
Overview: The document emphasizes the importance of drinking water hygiene and sampling, focusing on compliance with European and German regulations to ensure safe drinking water. It covers the legal framework, inspection requirements, and the role of materials and safety devices in maintaining water quality.
Regulatory Framework: The European Drinking Water Directive 98/83/EC and the German Drinking Water Ordinance establish legal standards for drinking water protection. Amendments in 2011 and 2012 introduced stricter provisions, particularly concerning legionella and materials used in water systems.
Materials and Safety Devices: Section 17 of the ordinance mandates that materials meet the German Federal Environment Agency's standards. Safety devices are required when connecting drinking water installations to non-secured devices or non-potable water conduits.
Drinking Water Sampling: Regular inspections for microbiological parameters, especially legionella, are required for public and commercial systems. The document outlines the systemic inspection process, focusing on central parts of installations like distributors and heating systems.
Inspection Requirements: Inspections are mandatory for large-scale plants, characterized by specific water heater and pipeline volumes. Public buildings must be tested annually, while commercial buildings every three years. Operators are responsible for compliance and can face legal consequences for violations.
Sampling Procedures: The document details the selection of inspection points, which should be conducted by trained personnel. It distinguishes between general and extensive inspections, specifying sampling points and procedures according to DIN EN ISO 19458.
Products for Sampling: Various models of sampling valves and related products are described, highlighting features like lead-free materials, ease of installation, and adaptability to different systems. Disinfectants for maintaining water quality in mobile supply systems are also mentioned.
Specifications and Standards: The document references DIN EN 806-4 and DVGW worksheet W 291, which outline common disinfectant chemicals for water distribution systems, including hydrogen peroxide, chlorine dioxide, and sodium hypochlorite.
Disinfection Procedures: For standpipes, hydrogen peroxide-based applications are primarily used. The Federal Environmental Agency's list, in accordance with the Drinking Water Ordinance, includes substances like calcium hypochlorite, chlorine, and sodium hypochlorite for water disinfection.
Hydrogen Peroxide Considerations: Hydrogen peroxide is aggressive and can damage materials if residues remain. Post-rinsing, the rinse water's pH must be checked to ensure all residues are removed.
Sodium Hypochlorite Disinfection: BEULCO Clean, a sodium hypochlorite-based disinfectant, is used during rinsing to flush out contaminants. The disinfectant is added via a dosing pump at a 3% ratio. The effectiveness is measured by the redox value of the rinse water, with a target range of 650mV - 700mV indicating germ-free conditions.
Process Duration and Efficiency: Standpipe disinfection takes 6-10 minutes, depending on conditions. Approximately 20 liters of BEULCO Clean can disinfect 20 to 40 standpipes. Sodium hypochlorite prevents germ resistance due to its immediate action.
Sustainability: BEULCO Clean is fully biodegradable.

Drinking water hygiene and drinking water sampling - H Drinking water, as the most important food, occupies a high status in the european legislation. It is intended for human use and consumption and thus its particular protection is an obligation. The European Drinking Water Directive 98/83/EC and the German Drinking Water Ordinance stipulate the legal requirements for the special protection of drinking water. This means drinking water systems must be planned, built and operated in such a manner that hazards and illnesses are not caused by the installation. This applies to the complete water...

Dinking Water Hygiene / Drinking Water Sampling - H Sampling of Drinking Water The European Drinking Water Directive 98/83/EC and the German Drinking Water Ordinance stipulate the legal requirements for the special protection of drinking water. This means drinking water systems must be planned, built and operated in such a manner that hazards and illnesses are not caused by the installation. Current standards and regulations set by the Federal Environment Agency and the DVGW also deal with this issue. Maintaining an overview of all the regulations is often a challenge in and of itself. Often,...

Which Drinking Water Systems have to be tested? The Drinking Water Ordinance prescribes regular, systemic inspections for legionella for all public or commercially used high-duty systems in the terms of the DVGW Code of Practice W 551. The term 'systemic' makes clear that the inspection procedure does not involve the determination of a lack of legionella at all individual outlets, but rather a sample test to determine possible contamination with legionella in parts of the drinking water installation that can have an influence on a larger number of outlets, in particular in the central parts of...

Dinking Water Hygiene / Drinking Water Sampling - H Inspection points for drinking water sampling The selection of the representative inspection points is conducted by means of a visit or on the basis of the available documentation for the drinking water installation in coordination with the responsible public health department. The standards of the DVGW Code of Practice W 551 and the Federal Environment Agency must be observed. According to the recommendation of the Federal Environment Agency, the ‘inspection points are to be selected by personnel trained in hygiene issues (e.g. technical inspection...
