Water Purification

Water, Wastewater and Sewer Purification

Increased populations and energy costs, aging infrastructure and ever changing regulatory requirements are putting water systems and communities at risk. This combined with reduced funding, increased security concerns and an aging workforce are creating the perfect storm. That’s why finding a partner who understands the industry and the intense wear and tear on this type of equipment is critical for OEMs.

In June, global water consulting engineering firm Black & Veatch released its second annual report highlighting the top 10 concerns for the water and wastewater industries. Not surprisingly, aging infrastructure ranked as the No. 1 issue, with related problems such as capital and operational costs following right on its heels.

Over 60 years ago, Hardy Machine began manufacturing parts for the water industry. While the business has grown to other industries, we have always stayed true to our core roots—producing high-quality, tight-tolerance components for equipment that must stand up to the high and low pressure of liquids and gases. Hardy Machine can manufacture and assemble critical components for clean water such as:

  • Chlorinators
  • Metering valves
  • Mixing valves
  • Inline ultraviolet sterilization equipment
  • Much more


  • Plastics
  • Precious metals
  • Nickel alloy
  • Stainless steel

We welcome on-site customer joint inspections required by government and the equipment manufacturing standards of the water purification industry.

We are ISO 9001: 2015 compliant and we go beyond these standards to meet the needs of our water purification Industry customers.

“Hardy Machine has been a reliable vendor. Dependable with excellent quality. Especially good with plastics.”
