Municipal Water & Wastewater — rehabilitation with minimal excavation
Pipeliner rehabilitates existing pipe networks with minimal excavation, without causing unnecessary downtime for the client.
We have lined more than 30,000 meters of drinking water pipe in Norway
Pipeliner delivers trenchless pipe rehabilitation to municipal water and wastewater customers across Norway. The method expertise is the same regardless of location — DieDraw™, full-structural CIPP lining and documentation are standard on every project.
We have documented references from Bergen, Oslo and Kongsberg, and can mobilize to any municipality. We are active on Doffin with registered CPV codes, and hold third-party approved products for drinking water and wastewater in accordance with NS-EN ISO 11295 Class A.
What we deliver to Municipal Water & Wastewater
CIPP full-structural lining
Full-structural lining IBB16 for drinking water and wastewater. NS-EN ISO 11295 Class A. Third-party approved products. Minimal excavation — minimal traffic impact.
DieDraw™ — PE pull-in
PE pipe is pulled through the existing pipe via a Die funnel — giving maximum internal diameter. Hallingplast-guaranteed 100-year service life (used in Kongsberg and Bergen, totaling 800 m DN400).
LIDAR/3D condition mapping
Robotic cleaning and internal condition mapping with LIDAR/3D documentation. Gives the municipality a complete digital condition report as a basis for prioritization and tendering.
PE pipe systems for newbuild and expansion
Prefabrication of PE pipe from Odda Plast — shorter lead times and good availability. Complete pipe systems for new pipe runs and capacity expansions.
GRP elevated tanks
Herde Kompositt delivers GRP elevated tanks. Prefabricated — shorter project time than concrete.
Framework agreement for municipal water and wastewater
A framework agreement gives the municipality predictable capacity, agreed response times and a fixed price structure — without a new tender process for each individual job. Doffin-compatible structure.
How we work with municipal water and wastewater customers
Whether it's an urgent pipe burst, planned rehabilitation or a framework agreement — SIGRA coordinates all disciplines according to the municipality's plan.
We review the condition of the pipe network with LIDAR/3D scanning and prioritize sections together with the municipality. No obligation.
Pipeliner, Odda Plast and Herde Kompositt come together on a single plan — pipe rehabilitation, PE pipe, GRP elevated tanks and documentation.
A framework agreement gives the municipality predictable capacity and agreed response times — without a new tender process for each job.
Four companies. One delivery.
