We help you to successfully solve your tasks
Trinkwasser Consulting has extensive knowledge and experience in treating even problematic raw water to produce high quality drinking water. The most important microbiological and chemical problems can be solved not only efficiently but also cost-effectively. We can advise you and provide you with further contacts.

We have created a free paper on an extended introduction to water supply.
Risk Management
We offer you support in setting up and developing a risk management system for raw and drinking water.
A risk analysis improves knowledge of your own system, increases resilience and reduces costs. We support you in training employees in risk management through online training courses, help you to identify critical points (risk analysis) and advise you on the design.
We have compiled the most important points for you as an introduction to the topic.
Optimization of water extraction, treatment and distribution
We advise you on issues relating to the quality management of raw and drinking water, raw water extraction, treatment and distribution as well as the communication of drinking water topics such as hygiene and disinfection:
- independent advice along the entire extraction, treatment and supply chain,
- support you in selecting the appropriate treatment stages and disinfection process,
- create training documents for the correct application of processes (good practice)
- support you in solving problems in drinking water, such as corrosion in the distribution network.
Management of research and development projects
R&D projects can improve water supplies at critical points and make them future-proof. We help you to formulate the topic, research the literature and check whether the topic has already been dealt with. We can also support you in your search for a suitable partner and accompany the project.
Contributions to water supply
We offer you free technical information and interesting articles on drinking water topics.
In articles and basic information we present important topics related to water supply.
Outlook: Future contributions will address the evaluation of drinking water treatment processes and online measurement technology for water quality control.
Advanced knowledge about drinking water for employees in water supply
Processes for Drinking Water Treatment
Drinking water is water that is intended for drinking, food preparation and other uses close to the body, such as washing. The World Health Organization (WHO) and the implementations in the countries describe what drinking water must be like. According to this, drinking water must be “pure”. It must not contain any pathogens and must comply with the limit values for bacteria. The relevant limits must also be complied with for physical parameters (e.g. turbidity, coloration) and chemical substances (e.g. metals, organic substances and pesticides). This ensures that the water does not lead to lifelong health problems. The water supplier is responsible for compliance with the limit values and is usually monitored by the health authorities.
Technical information: Risk management for the drinking water supply
Critical Points in the Drinking Water Supply
Drinking water is important for the preservation of human existence. The World Health Organization and member states recommend or require the implementation of risk management for drinking water. The goal of a risk management system is to make drinking water safer for consumers and to conserve resources. This means that suppliers need to be aware of this issue and its regulations. This information provides a brief overview of the topic and is intended as a starting point.
Drinking water is one of the most important resources for human life and health. To ensure the availability of water of good quality and in sufficient quantity, effective risk management is now considered essential at both international and national levels. This includes the identification, assessment and reduction of risks that could affect the quality and availability of drinking water.
Determination of Corrosion Rate and Instationary Corrosion of Low-alloy Steel
To investigate the effects of a corrosion inhibitor settling over an extended period, a two-part low-alloy steel pipe was taken from the drinking water network and installed in a test system. After an equilibration phase with inhibited water, the connected pipe sections were operated with inhibitor-free water for 600 days. During this time, stagnation tests were conducted to measure the increase in turbidity, oxygen consumption, and iron release. Corrosion rates and iron release rates were calculated from these parameters. Comparing the values at the beginning and end of the tests showed that the test pipe without the phosphate inhibitor did not exhibit a significant increase in the corrosion or iron release rate. The turbidity rates indicate that the legal limit for drinking water is reached after six hours of stagnation in the tested water. Under stable conditions, turbidity increased linearly over time, while oxygen consumption decreased linearly. Flushing significantly disturbed the corrosion system and increased the turbidity rate.
