Summary

In this video, the engineer explains the clean water system in a high-rise building, detailing the journey from the water source (PAM) to the ground water tank and then to the roof tank. The process includes the use of pumps, valves, and various components like strainers, flexible joints, and a balancing system. The clean water pump is activated based on the radar system, ensuring water is distributed to the upper floors. The roof tank's water supply is managed by pressure systems and booster pumps. The system is designed without a pressure reducing valve due to the building's height, ensuring efficient water flow throughout.

Takeaways

• 😀 The clean water system in a high-rise building starts with the water supply from the PAM (public water utility).
• 😀 There are three water meters, but only one is used to measure the water flow from PAM.
• 😀 The water from PAM is directed into a ground water tank, which consists of two sections: mainhle 1 and mainhle 2.
• 😀 The ground water tank has two outlets, one for the clean water pump (CWP) and one for the can water pump (CWP2).
• 😀 Various components like valves, strainers, flexible joints, and faps are used to control water flow from the ground water tank.
• 😀 The pumps work based on a radar system in the roof tank, turning on when the water level in the roof tank is low.
• 😀 The system features a distribution pump that moves water from the ground water tank to the roof tank.
• 😀 A firestopping system is used at each floor to separate different sections of the building and prevent fire spread.
• 😀 The roof tank, with a total capacity of 4,000 liters, receives the water transferred from the clean water pump.
• 😀 The booster pump system increases water pressure and covers three floors, supplying water to toilets and other sanitary points.
• 😀 The system relies on gravity and the booster pump to regulate water pressure, as there is no pressure reducing valve (PRV) installed.

Q & A

What is the source of clean water for the building?

The source of clean water is the PAM (water utility), from which water flows into the building's groundwater tank.

How many water meters are there for the PAM system, and how many are used?

There are three water meters for the PAM system, but only one is used for measuring water flow.

What is the function of the groundwater tank in the system?

The groundwater tank stores water from the PAM, and it is divided into two separate storage sections for balance. Water is pumped from here to the roof tank.

What kind of pipes are used for the water supply system, and how are they sized?

The pipes used in the system are 3-inch in diameter, and they carry water to different components like pumps and tanks.

What are the two types of pumps mentioned in the system, and what are their functions?

The system uses a Clean Water Pump (CWP) to pump water from the groundwater tank to the roof tank, and a Can Water Pump to distribute water for other needs.

How does the system ensure proper water distribution to the building's fixtures?

The water is distributed through a safe plumbing system, which includes both clean and wastewater lines. The clean water is transferred from the roof tank using the booster pump.

What is the purpose of the radar sensor in the roof tank?

The radar sensor in the roof tank monitors the water level and triggers the pump to activate when the water level drops.

What is the role of the booster pump in the system?

The booster pump maintains water pressure in the system, ensuring that water reaches the building's fixtures like toilets and faucets.

Why is there no Pressure Reducing Valve (PRV) in this system?

There is no PRV because the building is not very tall, and the system relies on gravity and the booster pump for pressure regulation.

What types of valves and components are used in the water distribution system?

The system includes valves, strainers, flexible joints, and pressure switches to control water flow and maintain safety throughout the building.
