Water Purification System Costs

Indoor Cost Guides      Water Filtration      Water Purification System Costs

Having potable water is necessary for all homes. Unfortunately, not all water supplies provide fresh, drinkable water. In the case of homes that have well water, sulfur water, or even just extremely hard water, a water purification system can provide a lot of benefits. This is a project that also has a number of variables in determining the actual cost of installation.

The biggest, and perhaps most obvious, cost variable is the type and size of the water purification system you choose. For example, investing in a portable water filter or pitcher is a nominal expense, but it can provide cheap filtered water for individuals and small families. Other common purification systems include: reverse osmosis system, ion exchange, distillation system, and carbon filter.

Water purification system: mid-range materials and labor costs.

Item Cost
Water purifier $20-$2,500
New plumbing lines and connections $90-$195
Water softener (optional) $500-$1,500
Total Cost $110-$4,195

Other considerations and costs

  • The best long-term option is to install a whole-house water purification system. It can cost a lot more upfront, but it will also garner a return on your investment in resale value. Plus, it ensures that all of the water in your home is as safe and pure for your family as possible.
  • Some homeowners opt to skip installing a purification system and instead choose a water delivery service. Dispensers range from $50 to $300 and delivery services charge an average rate of $8 for each five-gallon jug. If you rent your home or don’t want the hassle and expense of installation, this is an alternative.
  • Well water has special requirements for purification systems. You will need to hire a contractor to discuss your options, but these systems usually cost $2,500 to $3,000.

DIY considerations

  • Most basic DIY skills will cover everything you need to know to install a smaller purification system. Pitchers and sink filters are really easy, but even some of the more basic hard installs can be handled by a homeowner. This can save you money on labor costs.
  • Never install a purification system without checking local codes. Some towns and regions actually disallow certain types of systems from being installed. While you’re at it, find out whether or not you need a permit for this project.
