Putrajaya is a city planned and built to meet the challenges of the new millennium. It is A City in a Garden that turns to nature for inspiration, resulting in a landscape dominated by the picturesque Putrajaya Lake. A high standard of lake water quality is one of the most important factors for the success of this scenic centrepiece, and the solution was found in simulating yet another gift of nature - with the construction of Putrajaya Wetland.
