The stone ware sewers A. Are used for carrying sewage and drainage from houses B. Are manufactured from clays and shale C. After casting are dried and burnt at temperature 150°C, 700°C and 1200°C D. All the above

The correct answer is D. All of the above.

Stoneware sewers are used for carrying sewage and drainage from houses. They are manufactured from clays and shale, which are then dried and burnt at temperatures of 150°C, 700°C, and 1200°C. This process makes them strong and durable, and able to withstand the harsh conditions of the sewer system.

Stoneware sewers are a type of sanitary sewer. They are made from a dense, non-porous material that is resistant to corrosion and erosion. This makes them ideal for use in areas with high levels of groundwater or where there is a risk of flooding.

Stoneware sewers are also resistant to the growth of bacteria and other microorganisms. This makes them a good choice for areas where there is a risk of contamination of drinking water.

Stoneware sewers are a long-lasting and durable option for sewer systems. They can last for many years with proper maintenance.

Here is a brief explanation of each option:

• Option A: Stoneware sewers are used for carrying sewage and drainage from houses. This is their primary purpose.
• Option B: Stoneware sewers are manufactured from clays and shale. These are the raw materials that are used to make stoneware sewers.
• Option C: After casting, stoneware sewers are dried and burnt at temperatures of 150°C, 700°C, and 1200°C. This is the manufacturing process that is used to make stoneware sewers.

I hope this helps!
