Beenen and IAS Industrial Automation, both part of Batenburg Techniek, have been awarded a contract for the replacement of the process automation of another five sewage treatment plants of the Noorderzijlvest Water Board. The assignment concerns the supply and implementation of new process automation systems for the sewage treatment plants Onderdendam, Winsum, Wehe-den Hoorn, Ulrum and Leek. Obtaining the contract is the result of successful cooperation between the two Batenburg companies in accordance with the Best Value Procurement (BVP) tendering method.
Noorderzijlvest Water Board is a government organisation that provides safe dikes and quays, clean water in the countryside, treated wastewater and sufficient water in every season in a sustainable manner. Within this context, good process automation at the sewage treatment plants is crucial for the primary processes of the Noorderzijlvest Water Board (NZV). Without adequate process automation systems, effective and efficient operations within the wastewater chain process are not possible.
After successfully completing the selection phase and the concretisation phase, the contract was awarded to Beenen and IAS in early 2020. Completion of the projects is planned for the end of 2020.

Replacing process automation
This is why a project was started in 2016 to replace the technically and economically outdated process automation (1990s) of the sewage treatment plants. The variety of platforms for DCS and PLC/Scada resulted in inefficient and inadequate management of the PA systems. Functionally (in terms of the operation of the treatment plants), there were no explicit complaints from the operators, but the information needs of the business operations could not be met. In 2017/2018, the process automation for NZV’s largest sewage treatment plants was therefore based on ABB’s 800XA system. This project was carried out at the time by Beenen and IAS.
Now it is important to include the other treatment plants in the same quality standard (blueprint) and integrate them into the existing central control system. The task this time is to integrate five wastewater treatment plants into the previously established PA system and to add additional functionality. This time it concerns the sewage treatment plants Onderdendam, Winsum, Wehe-den Hoorn, Ulrum and Leek.
Quality-based tender: Best Value Procurement (BVP)
The Noorderzijlvest Water Board again opted to assess the tenderers on quality as well as price. The water board used the methodology of Best Value Procurement during the tendering process. BVP is designed to select the right supplier based on expertise. The aim of the methodology is to award the contract to the tenderer who has best demonstrated his ability to minimise risks and exploit opportunities (the best ‘performer’ or ‘expert’). Selecting the best party is also expected to result in the most economically advantageous tender. The client has formulated a number of objectives for the project, which must be achieved. The suppliers must demonstrate their ability to meet these objectives based on expertise and experience.
