It's not sensational. At present, per capita water consumption in the city is 1350 cubic metres, which is only half the national average. In urban areas, per capita water consumption is lower, at 228 cubic metres. Harbin has been included in the water-scarce city. At the 8th of this month's hearing on the price adjustment of water for living, it was announced that the price of water for the population was proposed to increase by $0. 6 per cubic metre. Under this programme, the increase of $21. 6 per person per year in the cost of water, which is clearly “unattractive” in tightening the “water**” in the ice city, is more of a cost-benefit calculation for the departments that have introduced the programme. In fact, water conservation cannot simply rely on economic leverage. New zealanders were paying special attention to water conservation, which was free in the country, and in new zealanders ' perception, wasting a glass of water would be tantamount to depriving future generations of a glass of water. In harbin, where the “alarm” for water shortages has been resounding long ago, it is imperative to develop the concept of water conservation. In order to build such a vision, it is important to consider that a government that is able to afford a significant number of its inhabitants cannot clearly rely solely on the market economy, but should also provide hard tools such as policy guidance and even market access。
Why is water saving better than electricity “thermal”? In the face of the “alarm” that water has already sounded and the price of the proposed increase, ice-cities do not seem to be “cool”. This can be seen in the choice of energy-efficient products by consumers - water-saving products are noticeably less sensitive than electricity- and oil-efficient products. Government subsidies, state tax cuts, promotions by manufacturers ... In recent years, the sale of various green and energy-efficient household electricity products and small-voltage fuel-efficient motor vehicles has been exceptionally hot, with strong incentives from national and local governments. An increasing number of consumers are paying attention to energy-saving indicators for products such as energy efficiency markers for household electric products and 100 km of fuel consumption。
However, in the case of water-saving products, some of the new energy-saving products, such as water-saving **, circulatory baths, etc., have been frozen. In recent days, journalists have visited health-save marketing malls and specialty shops on tagu street and pioneer road in the outer parts of the country to find that merchants are attracting consumers more with their products' materials, shapes and after-sales services, and that few of them play “water-saving cards” in a rational manner. In response, the seller of a brand of water** put it bluntly: the savings from water conservation are too small compared to the costs incurred and not attractive to consumers. He described the general household kitchen and toilet ** water as a trigger, which was often difficult to control and inadvertently increased the amount of water used; effective water conservation could be achieved if flow control valves were installed under water ** and the flow control was reasonable in the light of the water pressure of the house. In general, the flow of water saving** is 0. 046 litres/s, or 2. 76 kg/minute, while the flow of ordinary** is more than 0. 2 litres/s, or more than 12 kg/minute. Water conservation** can significantly reduce water waste. However, journalists have learned that since these flow control valves and water conservation** are expensive, consumers tend to spend money on water rather than on these water conservation products。
