High-rise secondary water supply is water tank or booster pump.

At present, high-rise buildings are basically supplied with secondary pressurized water, and most places use pressurized pumps to supply water without water tanks. If you are digging a well to get water, you may need to install a water tank or build a reservoir to store water. However, it also depends on well water production and user water consumption. If the output of well water far meets the user's water consumption, it is possible to use deep well frequency conversion water supply equipment. If you can't do it, you must install another water tank or build a reservoir outside the well.

What are the precautions for high-rise secondary water supply?

1. The material of water tank for high-rise water supply shall meet the requirements of drinking water standards, made of food-grade stainless steel, and corresponding protective measures and disinfection measures shall be taken to avoid secondary pollution. In the design, construction and completion acceptance of high-rise secondary water supply, health supervision and prevention should be strengthened to reduce potential safety hazards.

2, secondary water supply units should strengthen or establish the corresponding management system, regularly check the water quality and disinfection, it is best to set up a special person to manage, management personnel and cleaning and disinfection personnel must hold health certificates; The Municipal Health Supervision Bureau must strengthen the application and review of the residential property or unit health permit of the secondary water supply unit.

3. The health supervision department should strengthen the supervision and inspection of the secondary water supply units, regularly test the quality of water supply, put forward suggestions and take measures for the problems found, and impose high fines on the water supply units for drinking water that does not meet the national hygiene standards.

4. Do a good job in the publicity of residents' drinking water knowledge, enhance residents' awareness of health protection, prevent the spread of diseases caused by unsanitary water use, establish and publicize the telephone number of drinking water safety supervision in our city, so that residents can report to the municipal health pre-supervision department in time after discovering water quality problems, prevent the occurrence of drinking water safety accidents and ensure the safety of urban water supply.

What are the water supply methods for high-rise residential buildings?

1, water supply equipment mode without negative pressure superposition.

Simply put, the non-negative pressure superposition water supply mode mainly uses the pressure generated by compressed gas in the pneumatic water tank to supply water. Although it is quick and convenient, it also has some disadvantages. Because the capacity in the pneumatic water tank is relatively small, it can generally provide some help when the water supply pressure is low and the water supply flow pressure is low, which is the so-called pressurization equipment.

2. Series water supply mode.

The biggest feature of the series water supply mode of high-level water tank is that the equipment and pipelines are relatively simple, the price is relatively cheap and the energy consumption is small. However, the equipment of water pump has large floor area, high requirements for shock prevention and sound insulation, and inconvenient management and maintenance. The water supply in several upstream areas is affected and the reliability of water supply is poor.

3. No negative pressure box water supply equipment.

The characteristic of box-type non-negative pressure water supply is that the water flow is relatively stable under any circumstances and will not change because the flow of water supply network changes at any time. The main functions of this water supply mode are energy saving, environmental protection, totally enclosed protection and no secondary pollution of water quality.

4. _ Frequency conversion and constant pressure water supply equipment.

_ frequency constant pressure mode occupies a relatively small area, which can well avoid the harm caused by secondary pollution of water quality. If the water supply system is in a stable state of constant pressure for a long time and its flow rate is relatively stable, energy saving and environmental protection can be achieved through variable frequency speed regulating pump.
