Sacha 是一個室內建築空間設計師、及全面生活方式專家，與 Hugo 同樣熱愛城市探險，進入一個廢棄的濾水廠探索。
濾水廠建於1963年，後來人口增長，因規模較小，能夠處理水量有限，1995年開始被廢棄，已被附近其他濾水廠取代。內部日久失收，設備殘破，氣氛陰森，塗鴉處處。有不少電影在此取景，較出名的有周潤發與郭富城主演《無雙》的偽鈔工場。
城市探索的原則是除拍照外不取一物、不留痕跡和不公開地點。
Sacha, an interior architectural spatial designer and holistic lifestylist, ventures into an abandoned water treatment plant together with Hugo, both avid urban explorer.
The water treatment plant was built in 1963. As the population increased, its small scale and limited water treatment capacity rendered it obsolete. It was abandoned in 1995 and has been replaced by other nearby facilities. The interior is dilapidated due to disrepair with tattered equipment, lots of graffiti and gloomy atmosphere. Many movies have been shot here, and being used as a counterfeit money factory in “Project Gutenberg” by Chow Yun-fat and Aaron Kwok is well-known.
Urban exploration is based on the principles of take nothing except picture, leave no trace and not revealing the location.
