Water Pollution Control for Mandalay KanDawGyi Lake by Natural Treatment System

This paper emphasized on "Water Pollution Control for Mandalay KanDawGyi Lake by Natural Treatment System". KanDawGyi Lake is used for wastewater collection. It is situated in ChanMyaThaZi Township, Mandalay and near the AyeYarWaddy river. Residential, commercial and industrial area are existed surrounding the KanDawGyi Lake. Water from human activities such as cooking, bathing, washing and septic tanks effluent is discharged into drains by gravity flow without treatment. Average six million gallons of wastewater discharged from Mandalay City area flow into KanDawGyi Lake passing through ThinGaZar creek daily. So, lake water has been contaminated by domestic wastewater. 

This has resulted detrimental effects on the ecosystem. Water in recreation center should be aesthetically pleasing and essentially free of toxicants and pathogenic organisms. Seven collection points such as entrance, east of north side, south east of north side, south of north side, water fountains, PyiGyiMon barge and exit of KanDawGyi Lake are chosen to collect the wastewater sample. The water quality of KanDawGyi Lake is evaluated by various parameters such as temperature, turbidity, suspended solids, dissolved solids, pH, total alkalinity, total hardness, biochemical oxygen demand, dissolved oxygen, chlorides, total solids and bacteria. According to test results, alkalinity, chlorides, dissolved solids, suspended solids, and total solids are uncertified. Therefore, in this paper wetland design of natural treatment system is used at the entrance of the lake to control the water pollution.
