70 thousand
with the expansion of the urban area in two years. With the expansion of the urban area, the opening of tap water in Ji'nan is increasing. According to the statistics of the Ji'nan water service group, in the central city of Ji'nan, 550 thousand households were still in 2013, 580 thousand in 2014, and 620 thousand in 2015, with an average rate of 2 to 30 thousand per year.
the household water consumption of Ji'nan is also increasing due to the increasing number of households in Ji'nan. According to the statistics of the Ji'nan water service group, the peak water supply of the summer peak in 2009 reached 700 thousand cubic meters, increased to 800 thousand cubic meters in 2015, and increased by 100 thousand cubic meters only in 6 years. From 2013 to 2015, the use of tap water by Ji'nan residents increased by about 5 million 500 thousand.
the proportion of non resident water consumption dropped from 40% in 2009 to 35% in 2012. In a short span of three years, water consumption has dropped by 12 million. According to the analysis of the relevant staff, it is mainly due to the optimization of Ji'nan's economic structure and the relocation of some enterprises with high water consumption.
the per capita available water in Ji'nan is only 1/7
it is reported that the average level of water resources in Ji'nan is low. In normal years, the total amount of water resources in Ji'nan is about 1 billion 750 million parties. The dosage is about 1 billion 160 million, and the average 290 party is only 1/7 of the national average. Because of the shortage of water resources in Ji'nan, we can only rely on passenger water resources such as the Yellow River water and Yangtze River water to supplement.
at present, the daily water supply of the provincial capital is about 700 thousand tons. The 700 thousand tons of water mainly come from 5 major reservoirs and underground water sources, including the magpie mountain reservoir, Yuqing lake, the yuhushan and Jinxiu Sichuan reservoir, the wolf cat landscape reservoir and the East suburban water source.
although Ji'nan is a spring city, more than 8 of the residents in Ji'nan urban area come from the Yellow River water. At present, Ji'nan residents drink water mainly from the magpie mountain reservoir in the north and the Yellow River water diversion from the Yuqing Lake Reservoir in the west, which correspond to the two Waterworks of magpie Hua and Yuqing respectively. In the southern part of the province, there are three reservoirs: lying Hushan, Jinxiu Chuan and wolf Cat Mountain, which supply water for residents in the southern and eastern districts.
because the the Yellow River reservoir in Ji'nan is distributed in the western and northern provinces of the province, the water of the reservoir should be transferred to the urban area, and it needs to be pressurized by the first level and first stage pumping stations. The lowest point of the whole water supply network is about 23 meters above sea level, and the highest altitude reaches 200 meters in the eastern Longdong Cave, with a drop of nearly 180 meters. Therefore, six levels of pressure will be needed to send water to this place, plus from the Yellow River to the reservoir, from the reservoir to the water plant, and then from the water plant to the pipe network, and the three stage pressure in the early stage. Therefore, the whole process of water supply is required at most to nine levels of pressure to complete.
authorities clear
water saving man Yao lison: a five month water saving two or three party reporter Wang Chieh
the Dragon Jingyuan District of the home calendar is famous in the neighborhood. Water saving reaches people. She said that the implementation of the price ladder in Ji'nan is in favor of both hands, and the main purpose is not to collect more water charges, but to train the whole society's awareness of water saving.
in Yao Lisen's house, every drop of tap water flows out of the water pipe, which carries multiple tasks. Yao Lisen lived in a lot of flowers and plants, and every pot of flowers was flourish, and these flowers were irrigated with rice water. "Wash rice water for cooking, wash vegetables first, not only save water, but also remove residual pesticides on vegetables." Yao Lisen said, after washing rice and washing dishes, water is used to water the flowers.
for everyday families, laundry water is the "big head" of household water. Yao Lisen had a lot of experience. "If there are only one or two small pieces of clothes, wash them with small basins. I will only use a cylinder of clothes before I use the washing machine." Every time I wash the laundry, I leave it for the next laundry. "
in order to save water, Yao Lisen also reloaded the water pipe of his own hand washing pool, drained the wash water into the bucket with a hose, and then flushed the toilet with the water. "I thought my daughter was wasting the water every day, and I thought about it." Yao Lisen said that today, five people in the family each month use water at four or five or so, which is two or three times more water-saving than before.
, besides starting from the self, Yao Lisen also pays attention to training the water saving habits of his children and grandchildren. According to Yao Lisen, the daughter has just begun to reform his hand wash pool water pipe practice is not understood, "later she slowly adapted, also developed the habit of saving water."
