Issues in Water Piping Systems

Aging pipes causing rust and scale

Lack of Trust in Tap Water

Less than 5% of consumers drink tap water directly

    • Pipe Corrosion in Water Systems
    • Corrosion occurs throughout water piping systems, leading to secondary contamination (rust, scale, and bacteria)
    • Stainless steel and PET pipes develop scale, bacteria, and foreign substances within 2–3 years
    • → Increased chlorine use (bacteria persist)
    • Cost and Environmental Impact of Pipe Replacement

    • - Pipe lifespan: approx. 30 years

      - Estimated replacement cost: ~70 trillion KRW

  • Pipe Replacement
  • Rusty Water
  • Water Tank Contamination
  • Scale, Microorganisms, and Bacteria
Water Treatment Plant
  • Aging infrastructure (over 30 years) and outdated treatment processes
  • Chlorination produces trihalomethanes (carcinogenic byproducts)
  • Occurrence of midge larvae during the activated carbon treatment process
Water Supply Pipes
  • Many pipelines exceed their designed lifespan (30 years)
  • Aging pipes cause scale buildup and corrosion
  • Severe leaks increase water supply costs
Apartment Water Tanks
  • Inadequate maintenance leads to water contamination
  • Contaminated water is supplied to households
Household Water Systems
  • Aging pipes in older apartments cause rust
  • Stainless steel and PE pipes develop significant bacterial growth within 2–3 years
  • Bacteria in showerheads and contamination of drinking water filters

What Problems Occur in Water Supply Pipes?

Five Major Problems of Pipe Corrosion

As water supply pipes age, corrosion inevitably leads to rust, scale, biofilm, bacteria, and leakage.
As a result, water quality deteriorates and the lifespan of the pipes is reduced.

  1. 1. Slime
    • A viscous substance formed by the combination of inorganic and organic matter in water
    • Causes water quality deterioration through bacterial growth

  2. 2. Biofilm
    • Bacteria attached to slime produce byproducts during metabolism. These promote electrochemical reactions, leading to pipe corrosion.

  3. 3. Rust
    • Iron (Fe²⁺) reacts with water (H₂O) and oxygen (O₂) → forming iron oxide (Fe₂O₃)
    • Causes rust formation, leakage, and reduced pipe lifespan

  4. 4. Scale
    • Forms as deposits such as calcium carbonate (CaCO₃)
    • Adheres to slime and pipe surfaces, obstructing water flow
    • Occurs in all piping systems

    Scale in PVC pipe

  5. 5. Leakage
    • Primarily caused by internal corrosion within pipes
    • Continuous oxidation leads to localized damage
    • Results in pipe replacement and increased costs

배관 종류별 문제점
  • Stainless Steel Pipe
    Slime and bacteria develop within 2 years
    Partial corrosion occurs after 10 years
  • Copper Pipe
    Blue water occurs after 2 years (harmful to the human body)
    Commonly occurs in Korea
  • PE/PVC Pipe
    Slime and bacteria develop within 3 years
  • Cement-Lined Pipe
    Coating separation occurs
    Once corrosion begins, regeneration is not possible
  • Cast Iron Pipe
    Slime, rust, red water, and scale occur
  • Galvanized Steel Pipe
    Red water occurs after 7 years
    Leakage occurs after 10 years
    Pipe replacement required after 15 years
