HIGH RATE WATER TREATMENT PLANT SYSTEM: Successful Implementation and Financial Prospect

  • Mohajit Mohajit Institut Teknologi Bandung, Bandung, INDONESIA

Abstract

The High Rate Water Treatment Plant (HR-WTP) system, which is inexpensive, effective and efficient, has been developed to reduce the common operational problems, and also as an alternative for the development of water treatment plant systems capacity in Indonesia. HR-WTP-systems are a recent concept of water treatment plant design where engineering calculations are precise under conditions of operation so that the design can optimize the operation and process of the unit. HR-WTP-system is superior to those of conventional WTP-systems in respect to its capacity, performance, as well as operational liability of the system. For this reason, the investment cost is cheaper as compared to those of any other kind conventional WTP-systems. Implementation of HR-WTP-system in up-rating of the Dekeng- WTP system at PDAM Kota Bogor proved successful in increasing the plant capacity from its original of 500 Lps to more than 1200 Lps. Another successful application of HR-WTP-system was experienced inĀ  the upgrading and up-rating of the Pedindang-WTP system at PDAM Kota Pangkalpinang where the plant capacity can be increased from its original of 50 Lps to 300 Lps. The performance of the WTP-system was also significantly improved from poor performance to very good performance.The investment cost for up- rating proved competitive when compared to alternatively constructing a new WTP-system with an equivalent capacity and performance. Application of HR-WTP-systems for the development of WTP- system in Indonesia, i.e. rehabilitation, up-grading, and up-rating, as well as construction of a new WTP- system, is expected to bring technical, financial, and economic benefits. This new approach might be an innovative solution to the challenge of Millennium Development Goals in Water Supply Sector in Indonesia, where an additional capacity of ca 150,000 Lps should be developed within a 15 years period with an estimated budget of US $1.5 billions. This budget might be reduced to less than 50% through the application of the HR-WTP-system.
