SANITARY SEWER

The sanitary sewage system is designed for the disposal of domestic waste and the disposal of industrial and hospital waste. Sewage contains toxic residues, chemical residues, fungi, bacteria and micro-organisms that need to be safely transported to the treatment plant in order to avoid environmental contamination and preserve public health.

The use of HDPE corrugated pipes in sanitary sewage systems is advancing rapidly in Brazil, mainly due to 4 important factors:

1. Due to the lighter weight and the tip/bag coupling, the entire movement and installation of corrugated tubes in HDPE is much faster and cheaper;
2. HDPE pipes have high chemical resistance and do not suffer from corrosive corrosion due to the aggressiveness of domestic and industrial sewage residues;
3. The smooth internal surface in HDPE has greater hydraulic efficiency, allowing projects with smaller slopes and less deep installation, further reducing installation costs;
4. The tip/bag system with double sealing ring guarantees the watertightness of the drainage system, preventing damage and sinking in the paving of streets and avenues.

Tigre ADS storm drainage solutions provide easy and quick application, guaranteed watertightness, greater durability/life.

The SANIPRO® sanitary sewage line complies with the specifications of the NBR ISO 21138-1, NBR ISO 21138-3 and ASTM F2947 standards. Pipes undergo rigorous testing in our laboratories.
