  1. First BrazilianPVC Congress Sao Paulo June 7 – 8, 2005

  2. ObrigatoThank you! 1st Congresso Brasileiro do PVC

  3. Corrosion-Free Solution for Sustainable Water and Wastewater Systems Bob Walker, P.E. Executive Director Uni-Bell PVC Pipe Association First Brazilian PVC Congress June 7 - 8, 2005

  4. Mission Statement Help people gain access to safe, sustainable water and wastewater sanitation through the responsible and resource-efficient use of PVC pipes and fittings.

  5. Percentage of population with access to safe water by country, 2000

  6. Water is Fundamental – Yet: • Per capita availability is declining • 1.2 billion lack safe drinking water • 2.4 lack adequate sanitation facilities • 3 million die yearly • Water-born diseases account for ½ of hospital beds

  7. Benefits vs. Costs • Costs = Additional $11.5 Billion / Year • Benefits = $84 Billion / Year from Improved Health and Higher Productivity • Save Lives

  8. Biggest Economic Benefit? Time saved through more effective and efficient access and delivery.

  9. June 2003 • Successful installation of drinking water filtration and leach field systems • Villagers reported no sickness caused by consumption of contaminated water since this installation

  10. Tsunami disaster in Southeast AsiaDonations are welcomed. www.ewb-usa.org

  11. PVC – Inherently Well Suited

  12. We have critical pipe needs: • 14,000 people die everyday (worldwide) • 9,500 of these are children • Over 600 water main breaks per day (US) • Frequent and costly service interruptions • High leakage rates – lost water (~ 15%) • Over 6.8 billion gallons lost per day (US) • Direct Costs Exceed $98.6 million per day (US)

  13. Water main breaks are costly. A single break can easily cost $100,000 or more.

  14. Entire town of Northbrook, IL runs dry for 15 hours on Sunday 9.12.04 • System lost 1.5 million gallons • 24 inch cast iron main was installed in 1963 • Second break on that line in 30 years • Chicago suburb of 33,000 people has 100 water main breaks per year • 48 hour boil order in effect Chicago Tribune 9/13.04

  15. Reinforced Concrete Pressure Pipe Failure 1999

  16. Pikesville, Maryland – March ‘0436” Pipe Failure – 120,000 Homes

  17. What is the most serious and costly problem faced by water utilities? CORROSION

  18. What is the total annual direct cost of corrosion for U.S. drinking water and sewer systems?

  19. CORROSION In the United States alone,the total annual direct cost of corrosion for drinking water and sewer systems is $36 billion, which includes the costs of replacing aging infrastructure, lost water from unaccounted for leaks, corrosion inhibitors, internal mortar liners, external coatings, and cathodic protection.

  20. Fewer breaks = Substantial $avings

  21. Water Main Break Data on Different Pipe Materials for 1992 and 1993 •Research conducted by the National Research Council Canada (NRC) • Survey of 21 Municipalities Across Canada

  22. Water Main Break Data on Different Pipe Materials for 1992 and 1993

  23. Calgary Facts Update* Population of one million. Growth rate exceeds five percent per year. 20,000 + new households each year require the construction of 100 to 120 km of new water mains. Cost is increased by the necessity in Calgary’s climate to install water and sewer mains nearly 3 metres deep. Replacement costs are much higher than original installation, some 450 Euros/m of water main. *Roy Brander, P.Eng., Sr. Infrastructure Engineer, Waterworks, City of Calgary, MINIMIZING FAILURES TO PVC WATER MAINS, 2004.

  24. 2004 Update from Roy Brander • Calgary has installed nearly 2,000km of C900 PVC, now almost half of their system. • A similar length of metallic distribution mains sustains over four hundred repairs per year, with associated costs over 300 times higher than the infrastructure management budget for a similar amount of PVC. • The PVC break rate is so low that the usual unit of breaks/100km/year has become unwieldy, needing decimal places when engineers prefer small integers.

  25. 2004 Update from Roy BranderBreak rates for various pipe materials in units of (breaks / 1,000km / 10 years). • Poly-wrapped ductile iron: 3,000 – 4,000 • “Yellow” ductile iron: 300 – 350 • PVC pipe: only 13 – 17
