BEULCO drinking water hygiene and 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 procedures, 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 stringent requirements for drinking water systems to prevent hazards and illnesses. 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 requires materials to conform to the German Federal Environment Agency's standards. Safety devices are necessary if installations connect to non-potable water systems, ensuring compliance with DIN EN 1717.

Sampling and Inspection: Regular inspections for microbiological parameters, especially legionella, are mandated for public and commercial systems. The DVGW Code of Practice W 551 outlines systemic inspections, focusing on central parts of installations rather than individual outlets.

Inspection Points: Selection of inspection points is coordinated with public health departments, following DVGW and Federal Environment Agency standards. Inspections are categorized as general or extensive, with specific sampling requirements outlined.

Products for Sampling: Various models of sampling valves and related products are described, highlighting features such as lead-free construction, ease of installation, and adaptability for different sampling needs.

Disinfection: The document mentions environmentally friendly disinfectants like BEULCO CLEAN, effective against common waterborne pathogens, emphasizing the importance of maintaining hygiene in mobile water supply systems.

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 § 11 of the Drinking Water Ordinance, includes substances like calcium hypochlorite, chlorine, and sodium hypochlorite for water disinfection.

Hydrogen Peroxide: Known for its aggressive nature, it can damage materials if residues remain. Post-rinsing, the rinse water's pH must be checked to ensure all residues are removed.

Sodium Hypochlorite-Based BEULCO Clean: This disinfectant is used during rinsing to flush out contaminants. It is added to rinse water 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.

Disinfection Process: The process takes 6-10 minutes depending on conditions. A small amount of disinfectant can treat 20-40 standpipes with 20 liters of BEULCO Clean. Sodium hypochlorite prevents germ resistance due to its immediate action, unlike hydrogen peroxide, which can allow resistance during its residence time.

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...
