The municipality of Groningen is deploying two aerators in ponds in the city to maintain healthy oxygen levels.

The Groninger Internet Courant reports that aerators add oxygen to the water and are typically used during the summer months in order to ensure water quality is safe enough for fish living in the water. The municipality is working together with the Noorderzijlvest water management agency.
An aerator was first tested out in Groningen in 2017, and after that pilot proved successful, the city order two of them. The first one to be put into use this year is was introduced to the Floresvijver at the Floresplein by alderperson Joost van Keulen and Noorderijlvest representative Carla Alma.
Since last weekend, the city has been using pumps to move fresh water to the Pioenvijvers from the Gorechtkade ponds. Introducing other sources of water keeps the overall water temperature cooler, which also prevents the development of blue algae and keeps the water oxygen levels high enough for fish to survive.
In Drenthe, water pumps are being used at the Veendam pumping station in Hunze en Aa’s to increase the amount of water that can be pumped at the Veenkolonien. As reported in Dagblad van het Noorden, water authority Geert Jan ten Brink says that 2,000 extra liters of water are being pumped into the Vennix and Ter Apelkanaal to keep the former peat bogs from drying out.
