The aim is to strengthen the participants in their goal, to test water quality and operate a successful water laboratory. Contact us via for more information. We look forward to talking with you.

Our Trainings

Our Trainings take place on site, online or at our laboratory training room at Hagen Campus in Cologne (Germany). We have different target audiences at our trainings.

Water technicians

For many years we have been offering training courses for water and laboratory technicians to test water quality. The workshops and training courses offered are individually adapted and have a special focus on ensuring best practice in the use of equipment and quality assurance from the moment of sampling to data storage of test results.

Laboratory Managers

Running a water laboratory under limited conditions is a challenge. Could you imagine to even run it as a successful business model ?! In more than 12 years of practical experience we have identified 10 critical success factors for operating successful water laboratories as business models in areas of limited infrastructure !! We are glad to share our knowledge with international laboratory managers.

International experts

International consultants need sound knowledge in various specialist areas in order to be able to advise partners appropriately and make the best possible decisions. We are offering international expert trainings on water quality testing and running sucessful water laboratories under limited infrustructure conditions.

Successful Step-by-Step Approach

Workshop Examples

For Laboratory Technicians

Master your equipment

Hands on! Mastering your own equipment is very important. In this course the participants perform water quality testing in practice and receive a solid theoretical and practical knowledge on water quality and water quality testing with regard to the parameters tested.

Ensuring quality in work practice and data management

Data obtained from laboratory analysis are often used for making decisions. These decisions could be:

  • of considerable economic significance
  • used for improving the environment and community health and safety
  • related to regular and legal matters

Before going into the development of a Quality Management System, this course aims to communicate and ensure key Quality Assurance (QA) and Quality Control (QC) actions along the process of sampling, testing and data handling.

For Laboratory Managers and intl. Experts

Critical success factors for a well performing and financially viable water laboratory under limited conditions

Running a water laboratory under limited conditions is a challenge. Major challenges one often encounters are:

  • Limited financial resources / short budget lines
  • Unavailability and high costs for consumables and replacement parts
  • Inexperience regarding the right choice of testing equipment
  • Inexperience regarding suitable working processes in areas of limited infrastructure
  • Entities disregard the development of a quality management system and develop wrong habits instead
  • Lack of qualified workforce resources
  • Tendency to overdo things ending up in excessive micromanagement and frustration
  • Limited communication systems
  • Unfavorable climatic condition
  • Long distances and poor infrastructure (e.g. road conditions, power outages)

This course addresses especially the laboratory managers and other decision makers. The participants get to know and will discuss 12 critical success factors for running a laboratory under limited conditions - making the laboratory a stable entity capable of sustaining good quality services and being financially viable. The participants will start to develop critical tools, documents and a framework for upcoming tasks.

How to conduct a representative water quality baseline study

Conducting a representative water quality baseline study in a specific project area can be of interest to national and international organizations such as NGOs which are involved in the water sector. To be able to demonstrate the competence of generating trustworthy and statistically relevant data can mean a significant source of income which supports the laboratory on the way towards financial viability.

In this course the participants will learn about and develop the different steps of conducting a baseline study. Furthermore they will use the appropriate methodologies, tools and documents and do it practically.

Consulting and Coaching

Running a water quality testing laboratory in a setting that has a lack of infrastructure is a challenge. In more than ten years of practical experience, we have identified critical success factors to operate an independent water laboratory in a lower income country.

LETZTEST provides each of its partners with know-how on how to set up and sustainably manage a water laboratory.

After an onsite evaluation of your situation, LETZTEST offers you individually targeted support, with regard to financial planning, human resource development, a robust quality management system (in accordance with ISO / IEC 17025), long-term cost-effectiveness and financial viability.
