Using steel risers as rising main with submersible pumps is a past in world practice.
Company Hose Manufacturers, produces flexible rising main under the brand name "Boreline" for over 20 years and exports them worldwide, to many African countries, USA, South America, Australia and Europe.
Hoses are smooth, easy to install inside the well in one piece and convenient in confined spaces. Known for first class physical, mechanical, hydraulic i ecological properties. Suitable for the installation in the aggressive environments, isn't susceptible to corrosion, scaling or microbiological growth.
Excellent hydraulic characteristics enable diameter to be smaller than steel risers which ultimately reduces energy cost.
Boreline - advantages
• No corrosion, incrustation or scaling
• No microbiological growth
• Great tensile strength
• Excellent hydraulic characteristics
• Prestigious flow
• Up to 200 m length in one piece
• Supplied in compact roll
• Easy to store, handle and transport
• Easy to install and retrieval
• Small maneuvering space needed
• Satisfies all drinking water criteria
• Durable
• Easy to use in compact spaces

DOMESTIC PRACTICE
Investor: KRAŠ - ZAGREB
4" flexible rising main with submersible pump Pleuger installed in only one hour, using help from only one worker and drilling rig crane.
Comparison between heavy and corroded steel pipes, closely to 2 tons in mass and 4'' flexible rising main (with similar hydraulic characteristics), which easily fit in the trunk of the personal car.
Investitor: KRAŠ - ZAGREB
Investor: "VIRO" - VIROVITICA
Corroded and damaged steel pipes replaced with "Boreline" flexible rising main - using the drilling rig.
Investor: FARMA MAMIĆ - TENJA
"Boreline" flexible rising main simply and easily installed using off-road vehicle and rotating drum.
Investor: VODOVOD NAŠICE
Velimirovac water supply yard
Boreline flexible rising main use proved to be very useful. The pumping station was poorly designed with limited space. Hose installation done using tractor and rotating drum put on the pumping station roof.
