Antitrust rem eminder

  • Nickel Institute does not present forecasts or comments on

supply/demand, nickel markets or prices

  • We are committed to full compliance with the competition
  • r antitrust laws in all jurisdictions where our members are

active

  • NI Guidelines (NI website) provide an overview of areas of

legal risk

  • All participants in NI activities share responsibility for

adherence to the Guidelines

  • If any doubt exists about the appropriateness of specific

discussions or activities, legal advice should be obtained before they are undertaken

NI is committed to antitrust compliance

NI’s four priorities and strategic objectives

  • Nickel Classifications Management: Obtain classifications based on

sound science for nickel metal and nickel containing chemicals

  • Standards and Compliance for Health and Environment: Ensure

appropriate science-based health and environment standards for nickel and nickel-containing chemicals globally

  • Life Cycle Management: Demonstrate nickel’s valuable and lifelong

contribution to the economy and society

  • Promotion and Market Development: Build the nickel brand and grow

markets for nickel containing material; support existing and new uses

Water Loss Problems

  • 25 – 30% non-revenue water in most parts of the world
  • Some areas with more than 50%
  • Waste of precious water resource
  • Waste of water treatment, chemicals
  • Waste of electricity (4% of global electricity used in water supply)
  • Need for additional infrastructure
  • Need for additional dams and reservoirs

Other problems of water leaks:

  • Secondary damage due to flooding, road collapse, water damage
  • Hygienic concerns, ingress of contaminants at low pressure
  • High cost of maintenance to fix leaks

High Leakage Rate in Service Pipes

  • Material degradation (old systems)
  • Length of service pipe
  • Many joints
  • Joints are prone to leakage due to earthquakes, traffic, earth settling

Advantages of Corrugated Stainless Steel Service Pipe

  • Hygienic
  • Non-reactive with water (non-leaching)
  • Corrosion resistant
  • Long service life (100+ years)
  • Fewer connections, less prone to leakage
  • Strong, so connections can be tightened and slip-off force is high
  • Bendable, flexible:
  • Resistant to earthquakes
  • Resistant to soil movement
  • Resistant to traffic vibrations
  • Resistant to accidental mechanical damage
  • Resistant to frost damage

Corrugated pipes

Reduce the connections, reduce the rate of leaks

Traditional connections Corrugated pipes

Water Distribution – powerful arguments

Tokyo example:

  • Decrease of the leakage rate from

15.4% to 2.2%:

  • USD 200 million pa
  • Decrease of the number of water

leakage repair cases from 57,970 cases in 1980 to 9,774;

  • USD200 million pa
  • Advantage of long useful service

life of stainless steel >100 year

  • USD 45million pa
  • CO2 emissions – savings over

1980 emissions;

  • >700 k tonnes of CO2

Water Distribution – powerful arguments

Seoul example:

  • Decrease of the leakage rate from 27%

to 2.5%

  • Decrease of the number of water

leakage repair cases from around 60,000 cases to around 10,000 cases

  • Reduced water production from 7.3 m

to 4.5 m CMD

  • Reduced the number of water

treatment plants from 10 to 6
