Ecetas is both an infrastructure company
and a pipe manufacturer. Being a
contractor provides several benefits to
EBS clients, such as providing extensive
technical knowledge and supervisory
services. Ecetas is experienced in
the installation of sewage systems in
unfavourable conditions. The company
has wide knowledge, especially in sheet
pile applications in low bearing capacity
The installation of a new water
pipeline at the heart of Maidenhead
Town Moor, England, called for zero
environmental and social impact. The
use of polyethylene pipes from GPS PE
Pipe Systems enabled this aim to be
achieved.
Rich with wildlife, popular with visitors
and close to the town centre, the site
presented a challenge to the contractor
Clancy Docwra. Not only did it have
to minimise impact on the surrounding
area, it also had to return the Moor to its
recreational use as quickly as possible,
in time for a major public event in
August.
soils where the groundwater level is
relatively high.
Beyatas (Beton Yapı Elemanları Sanayi
ve Ticaret AS), a sister company of
Ecetas, produces concrete and
reinforced concrete pipes and fittings in
a variety of diameters and ready mixed
concrete in compliance with national
and international codes, in its factories
in Manisa and Adapazarı,
Turkey.
Derived from extensive
pipe manufacturing
expertise with its
two concrete pipe
manufacturing plants,

As the pipeline had to cross the Moor’s
waterside in three areas, directional
drilling was chosen as the optimal
technique to prevent disturbance to its
wetland habitat and species. Minimal
disturbance is achieved by digging a
pit at each end of the pipe section and
boring horizontally underground with
a removable drill head matched to soil
conditions and a series of drill stems
to push and rotate the head. The head
of the tool is steered from one pit to
the other using a mobile transmitter.
Once the pilot bore is completed, a
reamer is attached to the drill stem
and pulled back, enlarging the bore
to accommodate the pipe that is
subsequently pulled into place.
Pipes used in directional drilling must
meet exceptional demands, as they may
be pulled through underground tunnels
over considerable distances. South
East Water took advantage of Excel®
high performance polyethylene (HPPE)
pipe manufactured by Cambridgeshire-
based GPS PE Pipe Systems. With its
resistance to rapid crack propagation,
long term stress cracking and corrosion,

pipes manufacturing, the company now
offers to the Turkish and global markets
polyethylene pipes (PE100, PE80,
PE63, PE80 gas, steel wire reinforced
thermoplastic PE100, corrugated, metal
reinforced polyethylene) and GRP (glass
fibre reinforced polyester) pipes and
fittings, manufactured under the EBS
(ECE Pipe Systems) brand.
The manufacturing plant in Manisa
consists of a 7,500m 2 covered area and
50,000m 2 open area, including the stock
yard. Additional factory locations are
under construction for undergoing new
investments.
New pipe manufacturing machinery in
Manisa will broaden the EBS product
portfolio, resulting in an increased
capacity in plastic pipe manufacturing.

Excel has proven to withstand the heavy
loads associated with directional drilling.
In total 660m of butt-fused 500mm pipe
in SDR17 and SDR 11 was supplied to
complete the work.
With the watercourse left undisturbed and
less disruption to visitors, the work was
completed within the planned timescales
and all parties were satisfied with the
outcome. Installed by open-cut in the
‘dry’ sections of the pipework, Excel
reduced the installation time through its
ability to be ‘snaked’ into the trenches,
as flexible pipe strings welded from
multiple 12m lengths. The directional
drilling method also saved time.
The new £2.3 million pipeline forms
part of the wider £390mn five-year
infrastructure programme by South East
Water to secure future water supplies. Its
completion will see an extra 2.5mn litres
of water transferred from a nearby water
treatment works into Maidenhead’s
water supply network.
