BP in Geel has extensive water treatment facilities where used or polluted water is purified.
The water used at the BP plant is derived from the nearby Albert canal. Used or polluted water is purified and drained into the river Nete.
There are two types of waste water that need to be purified:
Processing water is drained off to the water treatment plant by way of an in-house sewer system.
Sanitary waste water is led to the water treatment by way of a separate sewerage system.
Furthermore, two types of water are drained off to the stabilisation pond:
Rain, snow, hail,.. is collected in an open canal system and brought together with the purified processing and sanitary water before being led to the stabilisation pond.
Water streams coming from the cooling towers, sand filters, etc drained off directly to the stabilisation pond because additional purification is not required.
