A NEWSLETTER OF DUCTILE IRON PIPE INFORMATION

Clow SuperLock for HDD

CLOW Super-Lock restrained joint ductile iron pipe is now available in sizes 6"-24" for horizontal directional drilling (HDD). This new technology for ductile iron pipe is rapidly growing in the water utility arena due to the following reasons: Iron pipe is impermeable to VOCs, is easily located, will not creep or stretch, larger internal diameters, strength and proven longevity of ductile iron. HDD is beneficial because of minimal disruption of traffic as boring is under sidewalks and streets, existing utilities remain intact, reduced environmental impact and cost effectiveness when concrete, asphalt or special landscaping requirements need restored to original condition. We inventory puller heads and pipe for quick delivery.

100 YEARS OF CONTINUOUS CAST IRON PIPE SERVICE

The City Of Quebec recently joined the growing list of Canadian municipalities that have achieved 100 years of continuous service with cast iron pipe. Opposite, at a ceremony held on Sept. 27, 1999, Ductile Iron Pipe Research Assoc. (DIPRA) Representative, Normand De Agostinis presents to Claude Cantin, Deputy Mayor, City of Quebec a plaque in honor of joining the "Century Club". This is an achievement, which is to be commended, and is an indication of an excellent choice of material, design and maintenance program.

NEW TRANSMISSION MAIN - CITY OF SENNETERRE, QUEBEC

The City of Senneterre, in the Abitibi region of Quebec, has completed the installation of their new trans-mission main. The use of an existing open lake as a source of drinking water had certain risks in regards to the quality of water. The Stavibel Engineering Company of Val d'Or was given a contract to find a solution to the City's concern. They decided to drill three new well fields for a source of clean water. To distribute water from these wells to the City and to service an industrial park along the route, the City of Senneterre installed, in total, 5,400 metres of 450 mm and 5,300 metres of 400 mm diameter Ductile Iron Pipe, Pressure Class 350. The main operates at varying pressures, between 650 - 750 kPa. The first phase consisting of 4,500 metres of 450 mm diameter was installed and completed in 1997 by Construction Val d'Or. The second phase, which consisted of 900 metres of 450 mm and 5,300 metres of 400 mm, was constructed and completed in July 1999 by J & R. Savard Company of Canton Tremblay in Saguenay.

In the second phase, due to corrosive soil conditions along the pipeline route, it was decided by the Project Engineer Mr. Gilles Marcotte of Stavibel, to use polyethylene encasement to AWWA C105 specifications, because of its low cost and ease of installation on the total length of the main. (Stavibel did testing of soils with D.I.P.R.A.'s assistance). Mr. Roland Lamarche, the Manager of Public Works for Senneterre stated, "we are quite satisfied in using Ductile Iron for transmission mains as it complements the balance of our system which is also Ductile Iron." We at Canada Pipe, congratulate all parties involved in this project for a job well done.

WHAT A DIFFERENCE A DAY MAKES!
Town of Amherst, Nova Scotia

On September 23rd, after a deluge of rain had fallen over the past 36 hours, the Town of Amherst experienced a complete road and culvert washout. What remained was sixty feet of exposed ductile iron pipe, still operating at 95 p.s.i. until work crews shut it down to make repairs. The Town's work crew were amazed that sixty feet of exposed main, with a vertical drop of eighteen feet, was still operating. As one official from the Town put it, "installing ductile iron pipe gives us strength and flexibility without compromise."
