Li Meizhen raises sea water to flush the toilet

Kuomintang Kaohsiung mayor by-election candidate Li Meizhen published a new policy on Facebook on the evening of the 7th, saying that after being elected mayor, he will discuss allowing citizens to flush toilets with seawater to solve the problem of "drinking separation"; yesterday (8) morning When the media questioned the overall plan, he kept skipping and responding to "discussed with experts,https://www.shineful.com.tw/ma57.htm, it is a long-term plan" and "no longer let Kaohsiung people carry water," but did not give a specific plan, causing controversy.

In response, Li Yuzhen, director of the organization department of the Taiwan Foundation Progressive Party, responded in a post on Facebook that the rough calculation of the cost of the pipeline alone would cost 329.7 billion yuan, plus the overall funding for the new pressurization station and distribution pool at least 400 billion yuan. Wei Jianshe".

On Facebook, Li Yuzhen analyzed the feasibility of flushing the toilet with sea water with the topic "The pipeline budget that Meizhen can't answer, Yuzhen tells you."

She said that the seawater system must be built separately from the tap water freshwater system currently in use. This is not Li Meizhen’s first creation. In fact, in Hong Kong, where there is a serious shortage of fresh water and a high population density, sea water is used to flush toilets in some areas close to the sea. However, the seawater is filled with chloride ions. It is very common to use seawater in pipelines. Crevice corrosion and pitting corrosion are very common. However, "additional water quality treatment facilities, transportation operations and maintenance costs are very expensive." "The total length of the Kaohsiung Taiwan Water Company's water pipeline is 7,428 kilometers, and 101 kilometers will be replaced from 2014 to 2015, and the cost is about 956 million yuan. Simple estimation, if the pipeline of the same length is simply constructed, the cost is about 70.3 billion yuan." Li Yuzhen explained that the cost of water pipes alone is prohibitively high.

She went on to explain, "The trouble is that each household has to take over to the home and install it on the toilet tank, including survey, design, pressure test costs, water connection points, water meter sets, water connection fees, and pipelines during actual installation. The cost of labor and materials is nearly 10,000 yuan within 4 meters. Take Kaohsiung City as an example. Kaohsiung City is divided into 17,395 statistical areas, of which 4,959 water supply areas have a penetration rate of 100%. Each household is calculated based on the basic labor cost of 20mm PVC pipes (7920), while each household in a sparsely populated area is calculated based on the Tai Water Company's assessment of the untaken water supply fee (600,000), excluding the road repair costs, and the total Kaohsiung 1.13 million households The cost of sea water pipeline piping is about 259.4 billion yuan. That is, the pipeline cost alone is 329.7 billion yuan."

Li Yuzhen also emphasized that if seawater is introduced into the city, a new pressurization station and a distribution pool must be set up, and because the seawater is at the lowest point in the city, the pressurization station requires more tap water than the tap water sent from high to bottom. According to project unit price statistics, a height difference of about 45 meters requires a period of compression, and the cost of each compression facility is about 2.7 million yuan, and the road restoration costs during the excavation process are not included. It is safer to prepare 400 billion yuan.

Li Yuzhen finally said: "After spending 2.7 trillion kinds of sugarcane, Kaohsiung spent another 400 billion on flushing the toilet. The debt has exceeded 3.100 billion, which is more than 10 times the price of Han Yu's rant." Billion is not a dream."
