Heavy-Duty uPVC Sewer Pipes Built for Saudi Infrastructure
Sewer and drain pipes carry waste water and storm water away from buildings, roads, and industrial sites, and they need to perform for decades under heavy traffic loads, aggressive sewage chemistry, and Saudi soil conditions. Concrete corrodes from H₂S attack. Metal corrodes from groundwater.
4B Factory uPVC sewer pipes are immune to corrosion, chemically resistant, and structurally stable for a 50+ year design life. The smooth internal bore delivers excellent flow with minimal blockage risk and lower hydraulic gradients than rough-walled alternatives.

Sizes, Classes, Lengths & Standards
Our uPVC sewer pipes are produced across the diameter range Saudi contractors and water authorities need, from residential drainage to major trunk sewers.

SAS 1395 & SAS 1396 — uPVC Sewer Pipes Saudi Arabia
Saudi project tenders specify SAS 1395, SAS 1396, or both. Here’s the practical difference between them.
SAS 1395 — Above/Underground Building Drainage
Covers uPVC pipes for above-ground and underground non-pressure drainage within and immediately around buildings — soil and waste stacks, ground discharge, and compound drainage runs.
SAS 1396 — Underground Sewerage Networks
Covers uPVC pipes for buried sewerage and drainage networks — the trunk and branch infrastructure connecting buildings to municipal mains. The standard used by NWC and municipal authorities.
4B Factory sewer pipes comply with both standards depending on size and class. We supply test certificates, material declarations, and compliance documentation suitable for NWC submittal and consultant approval. For pressure-rated water networks, see our Watermain Pressure Pipes page.

Frequently Asked Questions for uPVC Sewer Pipes Saudi Arabia
Common questions from contractors, consultants, and procurement teams sourcing uPVC sewer pipes in Saudi Arabia.
SAS 1395 covers drainage within and around buildings. SAS 1396 covers buried sewerage and drainage networks. 4B Factory pipes comply with both depending on size and class.
Class 2 = light-duty shallow drainage. Class 3 = standard municipal sewerage. Class 4 = deep burial, heavy traffic loads, industrial. Your consultant specifies the class based on burial depth and load calculations.
We manufacture up to 710 mm in-house. For larger diameters, contact our technical team to discuss requirements.
Yes, manufactured to SAS 1395/1396 matching NWC technical requirements. We supply full submittal documentation with every project order.
Yes, for diameters 160 mm and above, rubber ring jointing is generally preferred. Both rubber ring and solvent cement joints are available.
uPVC is immune to H₂S attack (concrete is vulnerable), lighter (faster installation), smoother internally (better flow), and longer-lasting in Saudi conditions. uPVC is the modern engineering preference.
Yes. We sell directly to contractors, water authorities, and project teams. Send your bill of quantities for a formal project quotation.
Yes, bends (22.5°, 45°, 90°), junctions, reducers, end caps, and custom project fittings. See our Customized Fittings page for the full range.
