Standardisation of the electrotechnical installations of sewage purification plants

Witteveen+Bos, under contract to the Aa en Maas Water Authority, has developed and documented the design of the electrotechnical installations for the Oijen Sewage Purification Plant. This represents an important step towards the aim of standardising sewage purification plants. Witteveen+Bos is working closely with AARTEC Engineering to achieve this.

The Aa en Maas Water Authority aims to have access to clear electronic typicals (standard elements) for sewage purification plants. Witteveen+Bos’s role in this process is to provide the engineering side of the electrotechnical installation and process automation. The installation will be engineered right down to the specification level. AARTEC’s role is that of ‘details’ engineering expert. The hardware design will be documented using Eplan Macro Project.

The result is that external parties can use the Eplan information to generate an electrotechnical or implementation design. Additionally, the macro project can be used as a standard set of typicals from which electrotechnical or implementation design drawings can be generated, either manually or automatically. According to Wytze Jorritsma of Witteveen+Bos, this represents an important step towards the standardisation of sewage purification plants: ‘The Water Authority’s objective is to have a standard package - a blueprint - detailing how the electronic system is designed, preferably down to the finer details. We are now developing this standard. In the near future it will be possible to generate drawings of the electrotechnical installation with the push of a button.’

The strategic partnership between AARTEC Engineering and Witteveen+Bos means we are now able to develop and document this process of standardisation. ‘These two companies complement each other very well. At Witteveen+Bos we’re extremely good at providing advice and guidance, and solving complex challenges, during which our (mechatronics) thinking and applications transcends disciplines. As part of this process we convert major, abstract challenges into concrete solutions, paying attention to the smallest details. AARTEC, on the other hand, specialises in further refining the smallest details and in designing and automating the preparation of detailed electrotechnical diagrams. A perfect match.’
