下水道科學館 / Sewerage Science Museum

下水道科學館（位於札幌市北區）是可以快樂學習下水道的構造和環境問題的設施。將從下水道孔或沖水馬桶流到下水道的污水做淨化處理的過程，以模型或是解說牌來介紹。在地下4樓，有聚集雨水，直徑5公尺的水管可以參觀。札幌的小學生們在社會課的教學上也會到這裡參觀。

Sewerage Science Museum (Sapporo City Kita-ku) is a facility where people can enjoy learning about the sewerage system of Sapporo as well as other environmental knowledge. The process of purifying waste water and sewerage from manholes or toilets is explained using models and information panels. On the fourth level of the basement, visitors can see a real big pipe which is used to gather rain water. The diameter of the pipe is five meters. Elementary school students in Sapporo visit here in their Social Studies class. At the 3D theater, visitors can feel as if they were on a submarine in the sewerage pipe.
