The buried drainage pipe: constraints to be respected
When installing underground drainage systems on the private portion of a building, several constraints must be considered during implementation. While public applications are subject to strict regulations, including the requirement to use reinforced pipes with joints, private applications offer greater flexibility, which can be detrimental to the long-term viability of the installations. Wastewater and stormwater management systems, as well as those for discharge to septic tanks or the main sewer system, are governed by stringent standards to ensure their reliability. These installations must:
- To comply with the standards defined by DTU 60.33 and meet the installation rules for buried pipes in booklet 70
- Providing increased crush resistance (SN4/SN8): the pipes must have sufficient rigidity to withstand pressure and ground movement, as well as the passage of vehicles.
- Maintain a diameter of 100 mm
Since 2007, DTU 64.1 has required a minimum SN4 rating for pipes, excluding all lower-rated multi-purpose pipes. Despite these requirements, over 50% of installed pipes are unsuitable for wastewater and/or rainwater drainage or for use in septic tanks. Private drainage systems deserve the same attention to ensure their reliability and longevity.
“If in doubt: The SPANC (Public Non-Collective Sanitation Service) allows for the inspection of all systems
put in place and to answer questions regarding the implementation of the installed pipeline.”
Why choose the BatiVac SN4/SN8 drain pipe?
The BATIVAC SN4 or SN8 is a reinforced PVC drain pipe, designed by ATE to meet the strictest requirements in terms of quality, durability, efficiency, and environmental friendliness. It is covered by Technical Approval 17.2/25-375 and certified QB-68-01-375.
Quality and ecology
BATIVAC SN4/SN8 products are pipes that contain a significant proportion of recycled PVC . ATE designed the reinforced BatiVac to maintain the same quality characteristics and meet the same high standards as PVC made from raw materials.
While construction activities are essential, the sector is the third largest emitter of greenhouse gases. Underground drainage networks must therefore meet environmental challenges by combining performance and sustainability . The BATIVAC SN4/SN8 is fully aligned with this approach.
Economy and sustainability
Compact co-extrusion gives our products superior strength , ensuring exceptional durability. The BATIVAC SN4/SN8 represents long-term savings by eliminating costly maintenance interventions.
To minimize deflection during packaging, the 4-meter BATIVAC , blue for SN4 and gray-blue for SN8, is delivered on a pallet containing 3 wooden straps . This packaging allows for easy installation, facilitating adjustment of the 2% slope during implementation and minimizing deformation.
Tip: To mitigate potential problems and ensure the robustness of your installation,
ATE recommends installing the BATIVAC SN8.
