南北緯37度空間遊走

人工湖畔的首相官邸

宏願橋(SERI WAWASAN):三線車道鋼纜橋，橋長240公尺，寬21公尺。

宏願橋的中間位是一根約呈45度的尖柱，左右兩側有兩支半彎的鐵柱以及許多鐵纜支撐，乍看如一把箭在弦上的弓箭，暗示執政者期望馬國的經濟能夠一飛衝天成為經濟強國。

太子橋為三層式的現代複合橋，最上層供行人通行、中曾為單軌電車軌道、最下層為維修隧道。

如果有時間的話不妨搭小船遊湖

布城水壩(PUTRAJAYA DAM):為390英畝寬坐落於布城東南方，該水壩負責調節布特拉再也湖的水位並確保湖水流入屈奧河(CHUAU RIVER)。

布特拉再也湖為一個佔地650英畝的人工湖，湖區按英文字母編列的26個景點。

布特拉再也湖上共有8座設計非常新穎的橋樑，其中以宏願橋最受當地人歡迎，傍晚時分總湧現許多情侶，是人氣最旺的約會地點。

本來打定主意一定要趁機搭船遊湖，可惜不小心迷了路順利抵達的時間超過預期，人家已經打烊收工也就錯失這難得的機會。花個20-30MR就能更近距離接觸到布城各主要景點，真是恨腿生得不夠長!!!

Putrajaya Lake
The 400 hectares Putrajaya Lake was created by inundating the valleys of Sungai Chuau and Sungai Bisa. Construction was undertaken in two phases. The first phase of approximately 110 hectares involved the construction of a temporary dam across Sungai Chuau.

The dam was completed in May 1998 and the impoundment of the Phase 1A Lake commenced in September 1998 and was fully inundated in January 1999. The lake has been primarily designed to enhance the aesthetic appeal of Putrajaya. It is also planned to be used for sport and recreation as well as a tourist attraction.

Studies of the Putrajaya catchment, however, showed that the water carried elevated level of pollutants derived from upstream sources and outside of the Putrajaya development boundary. Future development of the Sungai Chuau catchment is expected to increase run-off and pollutant concentration will either be maintained or increased.

This is expected to result in increased pollutant loadings in Sungai Chuau and Sungai Bisa which drain into Putrajaya Lake. As a result, the use of constructed wetland as a natural treatment system was recommended to treat primary upstream inflow to the lake. The wetland is to be complemented by riparian parks and gross pollutant traps.

Putrajaya wetland is the first man-made wetland in Malaysia and one of the largest fully constructed freshwater wetland in the tropics. The 197 hectare project resulted in transforming an oil palm site into wetland ecosystem with the helps of modern technology and stringent environmental management methods in design and construction.

The wetland straddle the water courses of Sungai Chuau, Sungai Bisa and three tributaries. Their primary function is to ensure that the water entering the lake meets the standard set by Perbadanan Putrajaya.

To achieve this, the wetland have been planted with a variety of aquatic plants that act as a natural filtration system, removing nutrients and pollutants from the catchment water. They treat natural run-off from the 50.9 sq km Sungai Chuau catchment.

In addition to being a water cleansing and filtration system, the wetland also help in flood mitigation, nature conservation, ecotourism, recreation, research and education and protection against soil erosion. Construction of Putrajaya wetland began in March 1997 and was completed in August 1998.
