Drinking water pipes

Extrusion lines for infrastructure and building applications

The production of drinking water pipes requires reliable extrusion technologies capable of ensuring consistent quality, regulatory compliance, and uninterrupted production. In the construction sector, where technical and sanitary requirements are becoming increasingly stringent, the choice of the extrusion line directly affects the performance of the finished pipe, operating costs, and plant competitiveness. Bausano designs extrusion solutions developed to support drinking water pipe manufacturers in major international markets, with a focus on process precision, energy efficiency, and long-term value

Drinking water pipes

Pipes made of plastic are found in the entire drinking water supply network all over the world. They have pipe dimensions up to 1600mm and are used as supply pipes connecting water catchment areas with water treatment plants and drinking water reservoirs.

Plastic pipes with smaller diameters connect the water mains with the domestic supply lines, carrying drinking water to the end consumers. Pipes used to transport potable drinking water are made from different materials, from galvanized steel to PVC pipes, and generally these types of pipes use different material than drain water pipes. Bausano offers solutions to produce pipes for potable water transportation, from 12 to 1600mm diameter.

In the construction industry, drinking water pipes are critical components for building reliable, safe, and regulation-compliant water supply systems. They are used to connect public water networks to buildings and to distribute water within residential, commercial, and industrial facilities. In this field, material selection is essential because it influences service life, mechanical performance, installation efficiency, and compliance with applicable standards.

The most widely used plastic materials for this application are:

PVC-U, used for rigid piping thanks to its dimensional stability and chemical resistance.
HDPE, selected for its flexibility and pressure resistance, particularly in external connections and underground installations.
PP, used in indoor systems for hot and cold water distribution.
PEX, chosen for installations requiring high thermal resistance and easy installation.

The quality of the finished pipe depends directly on the extrusion process, which must ensure uniformity, dimensional accuracy, and continuous production.

Applicable standards and the adaptability of Bausano extrusion lines

Drinking water pipes must comply with strict regulations that vary according to the destination market and the specific building application. In Europe, production must support compliance with the Drinking Water Directive and the technical standards governing PVC-U and HDPE pipes. In the United States, manufacturers must meet NSF/ANSI requirements and AWWA specifications, which demand consistent product quality and full process traceability. In Latin America, national regulations are generally based on international standards, with particular attention to productivity and cost per meter of pipe.
As a manufacturer of extrusion lines for drinking water pipes, Bausano designs its systems to meet these regulatory requirements by adapting line configurations, process controls, and equipment according to the target market. This enables pipe manufacturers to serve multiple countries with a single technology partner.

Bausano extrusion lines for drinking water pipes

Bausano supplies complete extrusion lines for the production of drinking water pipes, designed to process PVC-U, HDPE, PP, and PEX across a wide diameter range, from typical building applications to large-scale distribution networks. The lines are engineered to ensure process stability, precise temperature control, and dimensional accuracy—key factors in meeting the tolerances required by international standards.
Unlike many solutions available on the market, which are often limited to standard configurations, Bausano extrusion lines are custom-designed according to the required production capacity, plant layout, and level of automation. They can also be integrated with socketing machines and downstream equipment.

Market comparison: investment and benefits for manufacturers

The investment required for a drinking water pipe extrusion line generally ranges from €200,000 to €700,000, depending on pipe diameter, automation level, and optional equipment such as socketing machines. Many competing systems focus on reducing the initial investment cost but often result in process instability, higher scrap rates, and production downtime, increasing the overall cost of ownership.
Bausano adopts a long-term value approach by designing extrusion lines built for durability, controlled energy consumption, reduced material waste, and greater production continuity. For pipe manufacturers, this means a more predictable return on investment and the ability to compete successfully in highly regulated markets with a reliable production system. Within this context, Bausano stands out as a technological reference for the production of drinking water pipes for the construction industry.
