One of the largest wastewater treatment plants in Switzerland: HUBER supplies manhole covers for extension of Basel WWTP

HUBER products for one of the largest wastewater treatment plants in Switzerland: Together with its Swiss partner company Helmut Breschan AG, HUBER is involved in the expansion of the Basel wastewater treatment plant (WWTP).

The Berching-based company is supplying over 200 SD7 manhole covers in various designs, including accessories.

The expansion of the Basel municipal wastewater treatment plant is progressing: one of the largest wastewater treatment plants in Switzerland is being expanded and adapted to the provisions of the new Swiss Federal Water Protection Ordinance. The plant is to comply with the latest legal requirements and regulations and, amongst others, is to eliminate micropollutants. After the expansion of the WWTP by ProRheno AG and the participating companies, the aim is also to largely remove nitrogen and organic trace substances from the wastewater in the future.

For this project in the border triangle Switzerland-Germany-France, HUBER is supplying more than 200 SD7 manhole covers in various designs, including accessories such as fall protection grates. The high-quality and very durable equipment is to ensure safe and reliable access to the manholes, which are frequently found on wastewater treatment plants.

Planning since 2008: commissioning expected in 2024

In 2008, ProRheno AG had decided to upgrade the municipal wastewater treatment plant ARA Basel (270,000 connected inhabitants and 520,000 population equivalents). These plans had been driven primarily by the new Swiss Federal Water Protection Ordinance: the planners recognised that the wastewater contained more and more micropollutants because an increasing amount of substances were finding their way into the wastewater. So far, these micropollutants could not be completely eliminated in the treatment process.

The total investment costs amount to more than 295 million Swiss francs. The contract value for HUBER is about 1.1 million euros.
