The water body and the wetland of Putrajaya consisting of 197 hectares is a distinctive component of the city`s development and identity. This wetland, which is reputed to be the largest constructed freshwater wetlands in the tropics act as a natural filter to ensure that the water that flows from existing rivers into the Putrajaya Lake is purified and the lake, remains clean and pure. It is designed to be a sustainable and balanced eco-system. It will cater for various uses including recreation, fishing, water sports and transportation. This paper will present a report on the regular quality water monitoring programme for the Putrajaya Lake and Wetlands. Water samples were taken at various points along the lake and analysed for suitability for water based recreation. The monitoring involves the measurement of odour, floatable, transparency, turbidity in the wetlands. Based from the samples determined in August 2002, the water quality in the wetlands and the lake ranged between Class I to II which is considered satisfactory, and hence is considered suitable for water based recreational activities. The sample collected at the last station has a coliform counts of 10,000 and is in compliance to the mandatory threshold value as stipulated in the Water Quality Requirements for Bathing Water. It was also found that the criteria for fishes and aquatic life propagation protection based on the general water quality parameters do not present a significant risk to these organisms and their consumption.
