Takao Water Works opened in 1913 to manage the storage and supplying of clean water., In present day, Kaohsiung city recognizes the facility’s water purification pools, purification wells and water meter rooms as historical preservation sites. A layer of turf covers the purification pool, with several ventilation systems throughout, though the former stone imitation entrance is gone. The purification well is a tall cylinder with a vaulted roof, emphasizing the porch’s design and inserts a sense of tranquility in the historical architecture. The small water measuring chamber at the foothills is influenced by the classical, European continental style, and its overall design is similar to the official office’s entrance with a porch, gables, embossed sigils and a richly decorated truss.
鼓山／打狗水道淨水池
打狗水道淨水池於1913年完工啟用，在打狗上水道系統中，肩負儲存和供給潔淨用水的調節功能，接收來自小坪頂水源地的水，並以地形位差供給住民，給水區域包括今日的旗後、哨船頭、哈瑪星、三塊厝及苓雅寮等地區。1920年改名為高雄水道，後來隨著高雄市人口增加而階段性提高給水能力，除了擴張鹽埕地區的管線系統，整體供水範圍還拓展至前金一帶，是高雄早期規模完備的上水道系統，為近代高雄市發展奠下重要的基礎，並沿用至今。
目前市定古蹟範圍包含淨水池、淨水井與量水器室。淨水池上方有草皮覆蓋，設有通氣設施數個，昔日仿石砌結構的入口則已不存。淨水井為一挑高圓柱體，屋頂為拱頂，入口更強調門廊造型，帶有歷史主義建築的沈穩感。山腳下量水器室小巧的量體受歐陸古典式樣影響，整體造型類似官署的入口門廊，山牆、柱頭、楣樑的線腳裝飾豐富。
