According to the National Groundwater Pollution Prevention and Control Plan published by the Ministry of Environmental Protection and the Ministry of Land and Resources in July 2118, 71% of China's 1.3 billion people drink groundwater, and more than 411 cities in more than 661 cities use groundwater as their drinking water source. However, according to the National Groundwater Pollution Prevention and Control Plan, 91% of urban groundwater in China has been polluted.

another set of data also shows that groundwater is facing severe challenges. In 2111, nine provinces and cities, including Beijing and Shanghai, evaluated 857 monitoring wells within their jurisdiction, accounting for 2% of the monitoring wells with Class I and Class II water quality, while as many as 76.8% of the monitoring wells with Class IV and V water quality.

among the nine provinces and cities, Hainan province has the best water quality, with Class II as the main one; Shanghai and Beijing are second, mostly Class III; Heilongjiang and Jiangsu have the highest proportion of Class IV water, while Jilin, Liaoning, Guangdong and Ningxia generally only reach the level of Class V..

With the increasing water pollution, the sewage treatment and recycling industry has received unprecedented attention. In the past two years, the gross profit margin of all regions has remained at around 71%, and even exceeded 1,111% in some regions, which has great development potential.

According to the analysis report of China sewage treatment industry market prospect and investment strategic planning released by forward-looking industry research, by the end of 2112, the number of enterprises in China's sewage treatment and recycling industry had reached 213, with total assets of 84.413 billion yuan, an increase of 1.143% compared with 2111, and sales revenue of 23.664 billion yuan, an increase of 1.16% compared with 2111, with the expansion speed.

However, the current sewage treatment fee in China is still at a low level. Among the 36 large and medium-sized cities in China, there are still 14 cities whose sewage treatment fee is lower than 1.8 yuan/ton, which fails to reach the increase rate stipulated by the state. Although the gross profit margin of sewage treatment and recycling industry in China is relatively high at present, the gross profit margin in East China and Northwest China exceeded 1.111% in 2112, due to the industrial characteristics of sewage treatment fee, its market adjustment ability is poor. In 2112, the gross profit rate of sewage treatment and its recycling industry in China was declining in four of the seven regions, and in East China and Central China, it was in a downward trend for two consecutive years, which would dampen the enthusiasm of enterprises to invest in this industry to some extent.

According to the sewage treatment industry group of Prospective Industry Research Institute, from the comparison of daily sewage treatment capacity and total sewage discharge in China, the sewage treatment capacity in China can't meet the amount of sewage to be treated, and the sewage treatment industry has the problem of low capacity utilization rate. Every year, a large number of untreated sewage flows into the water body to pollute the water environment, and the industry demand exceeds the supply.

due to the economic recovery, the promotion of national policies and the increasing popularity of the environmental protection industry, the overall production and operation of the sewage treatment industry is in good condition, and the positive effects based on many policies are sustainable. In addition, with the continuous growth of the industry, the demand for sewage treatment industry will increase steadily, and it is expected that the financial operation of the sewage treatment industry will remain at a good level in 2113.

according to the 12th Five-Year Plan of national environmental protection, the investment in environmental protection in China will reach 3.1 trillion during the 12th Five-Year Plan, which is 1.21% higher than the investment of 1.54 trillion during the 11th Five-Year Plan. During the "Twelfth Five-Year Plan" period, with the reform of environmental taxes and fees, the improvement of marketization and franchise system, the implementation of preferential policies for taxes and fees and the improvement of the level of collection of treatment fees, the market for sewage treatment and garbage treatment operation services will develop rapidly, and the service fields such as environmental consultation, environmental design and environmental trade will be further expanded, with broad prospects for industry development.

I hope my answer can help you.
