Since June 26 this year, Zhejiang has long been clear and hot, high temperature, high temperature and rain, and both high temperature days and high temperature numbers have broken through the historical pole value. On the morning of August 22, the press conference of Zhejiang Province's water conservancy drought resistance and water supply supply work conference was held in Hangzhou.

What is the drought situation this year?

As of now, our province has issued a total of 48 water and drought warnings. According to statistics from the Zhejiang Provincial Department of Water Resources, in the past 60 days, the province's precipitation was 116.6 mm, a record low since 1954 (less than 133.6 mm in 1967), 68%less than many years. Among them, Zhoushan is 79%less, Jinhua is 74%less, Taizhou is 73%, Wenzhou is 73%, and Luzhou is 71%less.

As of 8 am on the 22nd, the current total water storage volume of large and medium -sized reservoirs in the province was 24.686 billion cubic meters (75.5%of the water storage rate), which was 1.125 billion cubic meters from the same period, of which the current water storage capacity of Xin'anjiang Reservoir was 14.173 billion square meters (water storage storage storage The rate was 79.4%), which was 687 million cubic meters less than the same period.

What is the current water supply guarantee?

At present, the province's drought resistance and water supply supply situation is generally controllable. The province's water supply capacity is 10.144 billion cubic meters, with an average of 149 days. From the perspective of districts and cities, the water sources in the main urban areas such as Hangzhou, Ningbo, Jiaxing, etc. are relatively stable, and the water supply is sufficient. The number of confession days is more than 180 days.

From the perspective of the county, most counties (cities, districts) reservoir water storage days are more than 90 days. However, some counties (cities, districts) have a lot of water supply pressure, and the number of days in Cixi, Qingyuan, Cangnan, and Sushan is less than 60 days.

In terms of water supply in rural areas, some Shancun and Liancun rural water supply projects with Xigou Mountain and Shantang have been affected by drought. As of now, the water supply in the province has a population of 81,600, of which 73,000 water supply is tight, mainly distributed in Yueqing City, Taishun County, Tiantai County, Lin'an District, Tonglu County, Chun'an County, Wucheng District, Pan'an County, Liyun County Places; 58,600 people in water supply are mainly distributed in Linhai City, Xianju County, Jiande City, Chun'an County, Cangnan County and other places.

According to meteorological forecast analysis, the temperature of our province will continue to be high in the late flood season. If there is no typhoon influence or no regional centralized rainfall, the water storage capacity of the reservoir in the province will continue to decrease, and the drought may further spread. The inland areas in central Zhejiang may have a drought, drought and drought, and the water situation will be even more severe.

How to deal with the next step?

It is reported that the relevant departments of our province are currently in order to strengthen the monitoring and early warning of water conservancy and drought, scientifically dispatching water conservancy projects, strengthening water resources savings, and fully guaranteeing urban and rural water supply.

The next step will continue to strengthen water supply protection. The top priority is to ensure the safety of the masses, focusing on the water supply guarantee of remote mountainous areas and islands, and strengthening the inspection and maintenance of rural drinking water sources, diversion pipelines, water supply stations and water supply pipe networks to ensure the operation of water diversion, water purification, and water supply facilities and equipment. Safety. Guide the areas of tight water supply and difficulty drinking water, increase drought resistance, and use measures such as shafts, canal, and pipelines to open water. If the measures are still not allowed to ensure the use of water for the masses, the emergency management department will be required to organize coordination in a timely manner, and use fire trucks to send water to ensure the safety of the people's living water.

In addition, water management will be done. In accordance with the principles of "giving birth, then production, first saving water, then water adjustment, the precedent, reservoir, first, and underground", organize various reservoirs (water stations) to refine and optimize the scheduling plan. Strengthen the linkage of reservoir and water plants, according to the trend of water level, adjust the water supply plan in time to ensure water supply safety.

It is worth mentioning that the next step must be alert to drought and floods. Although the high temperature of the sun and heat continues, our province is still in the main flood season, still in the situation of heavy rainfall, and still in the period of typhoon. disaster.
