No Dig!
In Part 2 of our instalment, Neil van Rooyen looks
at the need for pipe replacement, and a business
case for trenchless technology.
By Neil van Rooyen, introduction by Tarren Bolton
W
ater, Sewage & Effluent’s
second part of a series on
a paper titled “Unlocking
economic
growth
in South Africa using trenchless
technology”, authored by Neil van
Rooyen who is a director at Chrysalis
Projects, outlines how trenchless
technology for pipeline installation,
rehabilitation, and repair can rapidly
and efficiently alleviate the service
delivery issues associated with
deteriorating pipeline infrastructure.

Van Rooyen feels that such an initiative
would require significant engagement
between local government and private
business — and his paper serves as a
catalyst to facilitate such dialogue.
In this issue, we bring you the
second part of Van Rooyen’s research
paper, which is the result of a call for
papers from authors invited to submit
proposals on the latest innovations in
trenchless technologies. It is a holistic
paper, and as such, it is published in its
original format and cannot be edited.

The economical and ecological advantages of trenchless
technologies means that valuable surfaces are protected, time-
consuming and expensive excavation and restoration work is not
required, and there are no traffic jams or diversions.
