experienced with this pipe thirty or possibly twenty years
after its instatiation. This of course Is true for any new
product. However, to raject the use of C-900 pipe solely based
on the argument that it may follow the path of asbestos cement
pipe is at the very least an unfair treatment of a new product.

The amount of information on P.V.C. AWWA C-S00 pipe Is
voluminous. An attempt has been made In Appendix ! (attached)
to summarize the major characteristics of P.V.C. C-900 pipe as
compared to the ductile fron pipe. Based on these comparisons
| can see no reason to reject the use of AWWA C-900 pipe In
this City. However, It Is Important to note that as with any
underground conduit the P.V.C. water pipe be installed
properly. Workmen (Contractors and our own City Waterworks
crew) handiing P.V.C. water pipe must fully understand the
vartous difterences In the physica! properties and the
installation of this pipe and ductile Iron pipe.

A hands-on training session was held on February ird,
1984 with the assistance of a supplier's technician to refresh
our Waterworks crew's pravious experience with P.V.C. water
pipe. Particular emphasis was placed on direct tapping into
this pipe for service connection installation. Feedback from
‘the crews has been positive.

Several major lower mainiand municipalities have already
accepted P.V.C. AWWA C-900 pipe in their subdivision standards
In recent years. The list includes the following:

ae Olstrict Surrey

be. District’ Burnaby

ce. District Coquitiam
d. District Matsqui

@. District Abbotsford
f. Township Langley

ge City of Langley

he. District of Delta

To date | am not aware of any problems which are
attributed to the fault of the pipe material. | am aware,
however, of several accidents Involving the use of P.V.C. water
plpe which were attributed to either Improper storage, handling
or installation techniques.

Within thea City, there already are two test sections of
P.V.C. AWWA C-900 pipe which were installed approximately nine
years ago. These test sections are currently still In use To
supply water within the St. Catherines and St. Albert
subdivision and along Mclean Avenue. Aside from some
difficulties which were encountered during the Initial
Installation (the details of which are very obscure) these test
sections have been virtually malntenanca free.
