Method   Advantages   Disadvantages   Costing
Water Conditioners   Output water is suitable for low sodium diets

Prevents Lime scale, water utilizing appliances last longer

Increases heating efficiency

Improves soap efficiency

Calcium retained, good for diet

Low running cost

  Won’t treat anything but specific hard water problems   Small Property – $95

Typical System – $155

Large Residential / Industrial – $450

Water Softeners   Prevents Lime scale

Increases heating efficiency

Lengthens lifespan of clothes

  Output water may not be suitable for drinking

Expensive to install and maintain

  $1400 Typical Unit + Installation

$140 / Year – Salt + Electricity

Activated Carbon (AC) Water Filters   Effective in removing organic contaminants from water, will also remove chlorine   AC filtration does not remove microbes, sodium, nitrates, fluoride, and hardness.

Assume that it wont remove lead or other heavy metals unless specified by the manufacturer

  Point of use system – $50+

Whole house system- $550+

Ultraviolet (UV) Water Filters   Generally kills 99.9% of bacteria and viruses

High Filtration Capacity (10 Gallons per minute)

  Only kills bacteria, doesn’t remove the dead cells and won’t remove other contaminants   approx $400
Water Distillers   Mimics the natural water cycle process.

Distilled Water is almost completely pure, free from all forms of contaminant

  Low Filtration Capacity (6 Gallons per day!)
High running cost (25 cents per gallon)
  $300 – $1500
Sand Filters   Removes most bacteria, and turbity.

High Filtration Capacity

Generally best used for swimming pools and ponds.

  Take up a lot of space
Sulphates and Calcium generally not removed
Reverse Osmosis   Removes substances that would otherwise cause the water supply to be unhealthy or unappealing, for instance foul tastes, smells or colors.

Removes Salts and Minerals (lead/mercury)

  Typically, reverse osmosis systems will only recover about 5% of the water that passes through them, the remainder of which goes down the drain as wastewater.

The storage unit for treated water will support bacteria growth unless regularly disinfected.

  From $220

+ Install

Replacement Membranes $100-$200
