Enough water in every season

We are working on ensuring good water supply and drainage. We are making agreements about water levels. And we are keeping a close eye on water levels.

Water levels and water level regulation plans

We carry out our work on water from high sandy soils in Drenthe to lower-lying areas in Groningen. We use different gauges to maintain the water level at the agreed level.

Winter and summer levels

Water levels vary between winter and summer. This is due to the demand for water.

Maintenance and inspection of watercourses

Clean ditches contribute to good water supply and drainage. That is why maintenance is necessary every year. We check ditches that play an important role in controlling water in the region.

Waterway management and obstructions

We manage waterways in our region: sufficient depth and width, safe and clean. Obstructions may occur.

Subsidence

Gas is located in a layer of rock at a depth of 3 kilometers. All soil layers above this rock layer are sinking due to gas extraction.

Water retention

Water can sometimes be scarce. Denk hot, dry summers, which are becoming more common. To maintain sufficient water in every season, more measures are needed to retain water in the area for longer.

Pumps, weirs, and locks

With the help of technical structures and installations, we can control the water in our area. Without pumping stations, weirs locks, this would not be possible. They must therefore continue to function.

Groundwater

Groundwater is all the water below the surface of the ground in the subsoil. Groundwater was once rainwater. The rainwater sinks into the ground until it can go no deeper.
