pdam_bontangPDAM Tenggarong

Completed in 2005, this plant supplies drinking water to the expanding city of Tenggarong in East Kalimantan. This city is targeted for major development as a tourism center. The Envitech EPC contract comprises a 100 litres/second WTP and a 50 litres/second WTP at a different location. Both plants treat deepwell water which has a high iron content.

Although the treatment process is conventional, a feature of the plant is that all tanks and vessels are of stainless steel construction, as specified by the Client.
