臺北自來水園區環境教育中心

蓄水池的蓄水量達5,050立方公尺，可供水至大稻埕地區。

過去作為「水位測量室」，建築物為磚與鋼筋混凝土所造，外觀漆上紅色漆料。建築物旁有一大片草原，約兩、三座籃球場大小，觀音山蓄水池便在草原的底下，此為臺北最古老的蓄水池。由於水池在地下，因此設置水位測量室，設有機械滾輪式的度盤水位計來測量水位。

此外，位於旁邊的「配水井」，作用是分配清水。配水井位於淨水池最後出水處，清水經此配水井後，即流向量水室計量後再供應市區用水；另外，配水井設有制水閥，可以控制出水量以調節重力自然流量。配水的重要性關係到居民的用水的出水量，是極為重要的設施。
This reservoir can hold water volume of up to 5,050m3, enough to supply the Dadaocheng area.
A "Metering Room," the building was made of brick and ferroconcrete, and its walls painted in red. There is a grassy area next to the building the size of two to three basketball courts. Taipei's oldest reservoir, Guanyinshan Reservoir, is located beneath. Since the reservoir was underground, the metering room was equipped with a rotary water gauge to measure the water level.
In addition, the "Distribution Well" next to the building was used to distribute the raw water. This well was located at the reservoir's final outflow location; the treated water traveled through this well to the metering room, then sent on to supply the urban district. This well was also equipped with a gate valve to control water volume so the natural gravitational flow could then be adjusted. Its role in water outflow to domestic households made this a crucial facility.
