Water Treatment Plant Costs?

Published on by in Academic

I have been conducting research on identification of water treatment plant in India and Southeast Asian countries.

I got to know that for a 10 MLD WTP installed in India, the capex ranges between INR50-60 Million.

Similarly, may I get any advise on the approximate CAPEX for installing 10 MLD WTP in Vietnam, Malaysia, Thailand and Indonesia?

  1. In sewage treatment cost is around 8 to 10 rs./kl.

    If you go for industrial etp it's 130 to 140. For zero liquid discharge.

    1. Hi Sir, Thanks for your response. I am not sure if INR 10/kl would be a conversion factor for the capex cost. Moreover, please let me know if it would be approximately similar for the other countries mentioned above?

  3. It depends on the technology and process employed. If it is a conventional plant (coagulation, clarification, filtration and disinfection) with fairly good raw water quality, it can be US$2-2.5 million. If water quality is very good so that only filtration and disinfection are required, It can be very much cheaper. Else if you need to engage enhanced pretreatment to remove COD, ammonia and other pollutants, you have to add on that cost. Or if you use membrane technologies like UF, the cost can be 15-30% higher but footprint can be saved. 

    Our RICS system is an affordable package water treatment system with capacity ranging from 30m3/hr to 200 m3/hr. Due to its unique and compact design, it saves cost up to 30% than the conventional system.

    1. Hello Mr. Steve,

      Thanks for your response

       

      I believe USD 2-2.5 Million is quite high a capex for installing a conventional water treatment plant with a capacity of 10 MLD in developing economies of Southeast Asia. Is it that you assuming the plants to be fully automated?

      As here in India, not every plant installed is automated and organisations tend to save a lot of money out of this.

      1. Hi Aayush, yes it is a fully automated plant with reasonable design and decent equipment. The cost really For manually operated WTP, if it also goes without online instrumentation,  you can save another 30-40%, I guess.

  4. If you are looking to treat industrial waste water it woud be best to treat it at source so that it can be re-used on site.

    This is very cost effective, as the equipment has a very long life span and if the waste water changes composition for any reason the equipment can be easily adapted.

    It is also possible for mutiple sites to have equipment that they share and by programming the equipment based on the effluence at each site it is just a case of pressing a different button at each site.

  5. One of the main issues that is a hot topic right now re costs is that annual Operation and Maintenance is critical! a high % of plants in developing counties stand not operational because this has not been accounted for diligently and budgeted at the beginning of such projects.

    1. We have found that most companies that look to put in Waste Water Systems, dont think about continuous costs as that is a different budget to the purchase.

      If they looked at the full picture they would save money and have more efficient systems. It is not necessarly the cheapest, to purchase system, that is the best and most cost efficient.

  6. Hi Aayush,

    The cost of a wastewater treatment plant depends on many factors like:

    1) Quality of Raw wastewater & Treated effluent means up to what level of treatment is required.

    2)  Use of treated effluent means will it be used for irrigation or flushing, in any process or in cooling towers 

    3) Area where to install the system means rural or urban

    4) is it centralized or decentralized plant means how big network area it's going to cover

    So collect all data to get the real capex & opex.

  7. One would need to take quite a few aspects into consideration 

    1. Capacity 

    2 Capex 

    3 O$M Cost 

    Many existing plants have already been constructed world wide so collecting data based on their construction cost and processes should be readily available  , if not get in touch with a civil engineering consultant Firm like GIBB or Royal Haskoning who specialize in these projects globally.

    The most important factor to consider is the O$M cost because that will be the deciding factor , will the plant generate enough money to sustain itself over the life period , is the community willing to pay for water services can they afford the services are national frameworks in place , is there land available  for the project how many people will have access to water generated from the plant.

    The capital cost will be determined by the capacity of the plant , have you got trained people and qualified people to run the plant , what type of water are you treating river water or ground water each plant has different types of treatment mechanisms 

    my advise is to contact the local civil engineering consulting firms and get all info from them ,
