At present, the per capita water occupancy in Harbin is 1350 cubic meters, only half of the national average. The per capita water occupancy in the urban area is less, only 228 cubic meters. Harbin has been listed as a water shortage city.

The hearing on the adjustment of residential water supply price held on the 8th of this month announced that the residential water supply price is proposed to increase by 0.6 yuan per cubic meter. According to this plan, after the price adjustment, each resident will increase the water fee by 21.6 yuan per year, which will help to tighten the ice city“ water tap ”Obviously, it is "unable to do what we want", and the relevant department that introduced this plan door The economic account of water supply cost is more important.

In fact, water conservation cannot simply rely on economic leverage. New Zealanders pay special attention to water conservation, and water in this country is free. In the concept of New Zealanders, it wastes one cup Water means that the offspring will lose a glass of water. In Harbin, where the "alarm" of water shortage has long been sounded, it is urgent to establish the concept of water-saving. In order to establish this concept, the government that must consider the affordability of a considerable number of residents obviously cannot rely only on the market economy, but also should take hard means such as policy guidance and even market access.

Why is it better to save water than to save electricity?

In the face of the "alarm" of water resources and the water price to be raised, the citizens of Ice City do not seem to "catch a cold". This can be seen from the choice of energy-saving products by consumers - the attention of water-saving products is obviously lower than that of electricity saving and oil saving products.

Government subsidies, national tax cuts, manufacturers' promotion pin ... In recent years, with the strong promotion of the state and local governments at all levels, the sales of various green, environmentally friendly and energy-saving household appliances and small displacement fuel saving vehicles have become extremely popular. More and more consumers have begun to pay attention to the energy-saving indicators of products, such as the energy efficiency labels of household appliances and the fuel consumption of 100 kilometers.

But in terms of water-saving products, some new energy-saving products such as water-saving Faucet , Cycle bathtub But he was treated coldly. Recently, when the author visited the sanitary product distribution malls and specialty stores in Taigu Street and Xianfeng Road, Daowai District, he found that most businesses attract consumers with their products' materials, shapes and after-sales services. Few businesses, like playing the "electricity saving card", play the "water saving card" to attract consumers with reason.

In this regard, the salesperson of a brand of faucet said frankly: compared with electricity and oil saving, the money saved by water saving is too little relative to the cost paid, which is not attractive to consumers. He said that the faucets in general family kitchens and bathrooms are pull handle type, and it is often difficult to control the flow, which inadvertently increases the water consumption; If flow control is installed under the faucet valve The water flow can be controlled reasonably according to the tap water pressure of the house, which can achieve effective water saving. Generally speaking, the flow of the water-saving faucet is 0.046 L/s, that is, 2.76 kg of water is discharged per minute; The flow of ordinary faucet is more than 0.2L/s, that is, the water output per minute is more than 12kg. The use of water-saving faucets can greatly reduce the waste of water resources.

However, the author learned that because these flow control valves and water-saving faucets are expensive, consumers often prefer to spend money on water rather than pay for these water-saving products.
