It is barely half a century since parts of the Thames were declared 『biologically dead』 because the river was so dirty.
半個世紀以前，泰晤士河部分水域的汙染程度嚴重到被認定生物無法生存。
But with the water now cleaner than at any time in living memory, entrepreneurs want to build a ￡10 million open-air swimming pool in the middle of the Thames in Central London.
但現在泰晤士河的水質比以往任何時候都清澈乾淨，一些企業家計劃耗資一千萬英鎊（約為人民幣9345萬）在倫敦市中心的泰晤士河中部打造露天泳池。
Purification specialists from Germany – which has the highest water cleanliness standards in Europe – have designed a system which the scheme’s backers say will ensure that bathing is safe for visitors of all ages.
德國的淨水專家為泰晤士河泳池設計了一套淨化系統，德國的淨水標準是歐洲最嚴格的。該項目的贊助人表示，通過這個淨化系統，泳池裡的水對所有年齡層的遊客來說都是安全的。
The Thames Baths at Temple Stairs on the Embankment will be surrounded by reed beds to filter water from the river before it is pumped into the 82ft by 32ft main lap pool, with a secondary filtration device underneath the poolside decking.
沿著泰晤士河堤岸的聖殿階梯往下便是泰晤士河泳池。河水先經泳池外圍一圈蘆葦地過濾後，再通過泳池旁蓋板下的過濾設備進行二次淨化，才被注入長82英尺（約為25米）、寬32英尺（約為9.8米）的主直遊區。
Health concerns have been raised about the project because of sewage overflows during heavy rain and the experience of comedian David Walliams, who suffered a bout of 『Thames tummy』 during a 140-mile charity swim in 2011.
由於下大雨可能帶來汙水外溢，加上2011年喜劇演員大衛 威廉士（David Walliams）在140英裡（約為225.3千米）慈善遊泳活動中的遭遇——因受到汙染的河水導致身體不適，有人擔心這個項目是否會引起一些健康問題。
But experts from German firm Polyplan, which has built natural swimming pools all over Europe, have come up with a solution.
不過德國Polyplan公司的專家們已經已想出了解決方案，這家公司承建了歐洲多地的天然泳池。
Tim Evans, director of British firm Gartenart, which is working on the project, said the water – unheated and chlorine-free – will be 『as clean as anything you would find in a mountain lake』.
項目參與方英國Gartenar公司董事蒂姆 伊文思（Tim Evans）表示，這些不加溫且不含氯的水乾淨得無異於你從山間湖泊取到的水。
The lido will have changing rooms, a 130ft ramp leading from the shore to the water, a plunge pool and a children’s paddling area, while a 4ft-high glass balustrade will protect swimmers from waves caused by river traffic.
這個公共露天遊泳池將建有更衣室、一個跌水潭和一個兒童嬉水區，且還有一條130英尺(約等於40米)長的斜坡從岸邊一直延伸到水裡。泳池外圍還將建成4英尺（約為1.2米）高的玻璃護欄，防止內河交通產生的波浪影響遊泳者。
Chris Romer-Lee, of Studio Octopi – the London architects behind the scheme – said he hoped an initial ￡300,000 to cover consultancy costs and other fees would be raised by crowd-funding, where members of the public can contribute to community schemes.
該項目幕後的建築師團隊——倫敦章魚工作室的建築師克裡斯·羅默-李（Chris Romer-Lee）表示，他希望通過眾籌的方式籌集前期30萬英鎊（約為人民幣280萬）的諮詢費和其他費用，並且希望每一位市民都能為這個社區項目獻出一份力。
If planning permission is granted, the lido could open late next year.
如果這一項目獲得了建設許可，泰晤士河露天泳池將於明年晚些時候對公眾開放。
