TYCO - The One Stop Shop
TYCO Water is well known for its steel and ductile iron
pipes, fittings and valves,
Tyco Water Services provides total pipeline renovation and
service solutions, from asset management and condition assessment studies
through to pipeline maintenance, repairs, renovation and even full
replacement of pipelines. Sewer, water, stormwater, irrigation, industrial
and process pipelines and related infrastructure can all benefit from the
technology and experience available.
The Tyco Water Services’ team of experienced
engineers, material scientists and field operatives undertake condition
assessment and asset management studies. Tyco utilises a variety of
techniques ranging from desk top audits through to field studies, which may
involve CCTV and GPR surveys, man entry traverse of major pipelines, sewer
inflow/exflow gauging, leak detection studies and assessment of pipe
materials with high tech instruments.
Tyco Water Services has recently taken delivery of
Pearpoint’s latest explosion-proof, steerable CCTV camera system with 600m
of cable. This is intended for surveying large pipelines and has already
completed over 20,000m of pipe survey, with reports compiled using Cleanflow
Repairs for non pressure pipelines, structural patch
liners, chemical grouting to internally reseal leaking joints and civil
works to dig out collapsed pipes and repair manholes are all undertaken with
in-house resources. Repair and maintenance of pressure mains is also offered
and includes valve and fittings refurbishment or replacement, cement mortar
lining repairs, cement mortar lining of unlined pipes, tapping under
pressure, AMEX 10 internal leak seals, leak repairs using Wang external
repair sleeves and civil works to repair mains breaks.
A major part of the Tyco Water Services’ toolbox is
its’ diverse range of pipe lining techniques. Tyco Water recognises that
one process alone is not suitable for all applications and for that reason
they offer the Permaline cured in place (CIP) liner for pipe diameters
100-1350mm, Sideliner for household pipe diameters 50-225mm, Twin Lok
grouted spiral wound liner for pipe diameters 300-750mm and the Panel Lok
grouted spiral wound liner for larger pipe diameters (600-3000mm).
If maximum capacity is required,
pipebursting using the Grundoburst hydraulic pipeburster can be used to
install a new PE or ABS pipe of the same size or larger. Replacement can
also be achieved by sliplining using PE, ABS or Sintakote Steel pipes, which
were recently installed for Sydney Water to replace a major water main in
none">Typical of the work that Tyco Water Services is performing is a
“rehabilitate all” project at Epping – part of Sydney Water’s
commitment to reduce sewer over flows and work closely with the EPA to
define improvement targets.
Part of this strategy is to work closely with qualified
contractors who specialise in trenchless technology rehabilitation of
underground pipelines. This represents a change in philosophy from the
previous minimalist approach.
Tyco Water Services’ Epping contract is the first of
these “rehabilitate all” projects, and involves lining all the pipelines
within a defined mini catchment including some 10,000m of mainlines, 600
house service lines and maintenance hole and other structural repairs.
The company introduced new technology with its “Permaline
Sideliner” house service lining system. This allows pipes with one access
point to be lined through the existing boundary shaft and around the bends,
including the boundary traps. This system gives a far greater longevity than
previous techniques of chemical flood grouting.
Tyco Water Services’ “Permaline” mainline system is
being used to line the main sewer lines. Since 1971 Cured in Place (CIP)
lining systems have proven to be the most reliable and are the world’s
leading and preferred lining system for pipe diameters up to 1200mm.
Tyco Water Services operates from offices in Sydney,
Brisbane and Melbourne.
