Bath sewage treatment plant

The Bath sewage treatment plant is one of the largest in the Netherlands. The plant is almost 25 years old and has an enormous processing capacity: the dry weather flow amounts to 3500 m³ per hour, while the rainwater discharge is 8300 m³ per hour. During heavy downpours the inward supply can be as much as 14,500 m³ per hour. This is equivalent to discharging the content of a complete Olympic swimming pool in 4 minutes. Polluted water is supplied to the Bath sewage treatment plant through the wastewater pressure line that starts in Moerdijk. On the way to Bath, the line gathers the wastewater of 35 villages and towns.

The Brabantse Delta Water Board wanted to renovate the sludge line, requiring an investment of approximately €12 million. Iv-Water worked out the draft plans into documents ready for specification. The draft plans concerned the primary sludge compression, secondary (or surplus) sludge compression and sludge dewatering.
