In 2015, the first plant in Kazakhstan for the production of reinforced-concrete non-pressure spigot pipes of Sapa Su LLP was opened as part of the State Programme of Accelerated Industrial and Innovative Development of the Republic of Kazakhstan.
Sapa Su produces all types of reinforced-concrete products using high-tech German equipment; these products are designed for civil engineering, road construction, sewage, sanitation, electric power supply, telecommunications, discharge treatment, and rainwater disposal.
Reinforced concrete products are made of the dry concrete mix using vibrocompression technology, which allows the products to have high technical characteristics, namely the increased service life. The average service life of reinforced concrete products used as non-pressure pipes is about 100 years.  

SAPA SU LLP‘s products are produced according to GOST 6482-2011 and meet all requirements for production. 
The bearing capacity of the reinforced concrete pipe is in Class 5 of load (with laying depth up to 10 m)
The main advantages of reinforced concrete structures include the following features:
•  low susceptibility to corrosion processes
•  compressive strength В 30 (М400)
•  water resistance (W6)
•  tensile strength;
•  resistance to low temperatures (frost resistance) (F 300)
•  resistance to chemical and biological media;
•  high strength and durability of the product;
•  crack resistance
•  affordable cost

Our spigot pipes were used in the following strategic facilities:
•  Utility networks of EXPO-2017 Exhibition Centre
•  Utility networks on Kabanbay Batyr Avenue, Astana
•  Facilities for regulating the level of the Maliy Taldykol lake. Development of stormwater sewer system in Astana.
•  Relocation of the stormwater sewer system for light rail transport construction project and other projects.

The company has its own production testing laboratory, where technical experts take inert material samples, examine the quality of finished products for compliance with standards, and monitor the indicators of physical, mechanical and physical and chemical properties.
