3. Construction cost:
Construction cost includes civil engineering and equipment installation costs.
● Civil engineering: including foundation construction, earth excavation, concrete pouring, etc., costing approximately $20,000-50,000.
● Equipment installation: including equipment hoisting, installation and commissioning, costing approximately $10,000-30,000.
The total construction cost is approximately $30,000-80,000.
4. Operating cost:
Operating cost includes staff wages, energy consumption, chemicals and daily maintenance costs.
● Staff salary: Depending on the size and automation of the water treatment plant, 1-3 operators are usually required, with a total annual salary of approximately US$20,000-60,000.
● Energy consumption: The electricity consumption of the water treatment plant is mainly used for equipment operation and pump work, with an annual cost of approximately US$10,000-30,000.
● Chemicals: The cost of chemicals used for water treatment, depending on the water quality and treatment volume, is approximately US$5,000-15,000 per year.
● Daily maintenance: Including daily maintenance and minor repair costs of equipment, with an annual cost of approximately US$5,000-10,000.
The total operating cost is approximately US$40,000-115,000.
5. Maintenance costs:
Maintenance costs include regular inspection and replacement costs of equipment.
● Regular inspection: Usually a comprehensive inspection is carried out once a year, with a cost of approximately US$5,000-10,000.
● Equipment replacement: mainly includes the replacement of membrane components, pumps and other equipment. According to the service life and replacement cycle of the equipment, the annual cost is about 5,000-20,000 US dollars.
The total maintenance cost is about 10,000-30,000 US dollars.
Total cost estimation of building a small water treatment plant
Combining the above costs, the total cost of building a small water treatment plant can be roughly estimated.
● Design cost: 20,000-50,000 US dollars
● Equipment cost: 70,000-210,000 US dollars
● Construction cost: 30,000-80,000 US dollars
● Operating cost (year): 40,000-115,000 US dollars
● Maintenance cost (year): 10,000-30,000 US dollars
According to the lowest and highest costs, the total cost of building a small water treatment plant is about 170,000-485,000 US dollars. If operation and maintenance costs are taken into account, the total expenditure in the first year will increase to between $270,000 and $630,000.
