How Much Does It Cost to Build a Water Plant?

by

Desalination Plant Costs

  • The average cost is $2,009. Costs range from $992 to $3,073.
  • A 10 MGD SWRO desalination plant costs $80 million. A 35 MGD plant costs $250 million.
  • Desalination plants cost $1 million per 1,000 cubic meters of daily capacity.
  • Construction takes 1-5 years depending on size. The preconstruction period takes 9-30 months.

Water Treatment Plant Construction

  • Building a pure water factory costs $5-7 million for land and construction.
  • Pond construction ranges $800-$80,000. Costs average $3,346 nationally.
  • Wastewater treatment plant costs range $25,000-$30,000 per 1 KLD capacity.

Timeframe for Building

  • Construction may take one to five years. The preconstruction period has taken from twelve to thirty months.
  • A fully-installed 1 to 20 GPM ZLD system will run $250,000 and $2 million.
  • Installing a whole house filter system takes two to four hours.

Cost and Factors for Water Treatment Plants

  • The cost of a water treatment plant varies $3.5 million to $15 million.
  • Factors that influence the cost include capacity, type of treatment, location, and public or private facility.

Industrial Water Treatment

  • Industrial water treatment serves industries through water and wastewater treatment.
  • Physical space impacts cost-effectiveness. Compact systems often cost more upfront.

Challenges and Considerations

  • Desalination is energy-intensive, making water costs higher than conventional treatment.
  • Urban growth strains wastewater systems, increasing treatment costs.
  • Developing countries lacking infrastructure have seen disease spread from poor wastewater management.
