Kalsbeek BV performs many audits for clients on location. The audits serve two objectives. Firstly, the audit on site checks that management and maintenance to the potable water system complies with the rules and regulations of the drawn-up water management plan. Even more important is the educative aspect of the audit. We not only check, but we also give a detailed explanation of the underlying reasons. We also explain the method of sampling. This will increase the awareness and give an understanding of the possible consequences in the event of inadequate management and maintenance to the system.
