We are a waste treatment company that generates revenue through design, development, manufacture, sales, installation, operation and maintenance of sewage treatment systems and by providing sewage treatment services. We primarily engage in two business lines: rural sewage treatment and septic tank treatment in both urban and rural areas.

For rural sewage treatment, we sell complete sewage treatment systems, construct rural sewage treatment plants, install the systems, and provide on-going operation and maintenance services for such systems and plants in China for municipalities and enterprise clients.

For septic tank treatment, we offer on site, or in-situ, septic tank treatment services with our proprietary systems in the urban and rural areas of China for municipalities and residential and business property management companies. We have developed both mobile and fixed systems to meet the various needs of our customers.

We have established sales and marketing networks in many cities across several provinces in China with fourteen majority-owned subsidiaries and two branch offices in China.

The core of our business is our proprietary systems and technology, together with our experience and expertise in waste treatment services, particularly in rural sewage treatment and septic tank treatment. As of December 31, 2019, we had two invention patents and nineteen utility model patents. We also had five pending utility model patents. We are continually working to upgrade our quick separation technology and septic tank treatment systems through independent research and development and partnerships with third-party institutions to further develop our mobile septic tank treatment system.
