The Great and Small Baltezers lakes, which are in a forested and sandy area, feature a unique system in Latvia – a water delivery zone with artesian wells and water filtration layers.  The system was in place in 1904, when the Baltezers pump station was opened.  In 1998, the Rīga Water Delivery Museum was opened in the station, providing information about the 400 years of water delivery in Latvia, including various mechanisms, ancient wooden pipelines, etc.  Around the museum is a boiler house, along with a machinery house, accommodations for workers, and mechanical workshops.
