Helsinki, Finland, has had to rely on a source of water that is highly polluted. Problems from a variety of tastes and odors have been troublesome. This article describes some methods used to improve the water prior to normal treatment. Investigations showed that pollution peaks would be minimized and that biological purification would occur if the water were stored for 3 or 4 weeks. A 1.3‐bil gal pear‐shaped reservoir was built on the side of a small hill near the river for pretreatment storage. The reservoir was completed in 1962. Model tests were used to determine the final shape of the reservoir and the location and direction of inlets and outlets for proper velocity and uniform circulation of water.
