2026 year 4 month 16 On the same day, Mr. Cai of Zhejiang Lingdui Urban and Rural Planning and Development Co., Ltd. and his delegation visited Hefei EPANEL Water Supply Technology Co., Ltd.. The two parties conducted in-depth exchanges on vacuum water technology, conducted comprehensive discussions on the core advantages, scenario applications and industry development prospects of vacuum drainage systems, and reached a number of in-depth consensuses.

The core technical principles and differentiated advantages of the vacuum drainage system were explained in detail at the exchange meeting. Different from the traditional gravity drainage model that relies on the weight of the water body to achieve top-down self-flow, the vacuum drainage system relies on the vacuum pump station to form a stable negative pressure difference in a closed pipe network, completely breaking through the restrictions of topography. It can efficiently pump residents' domestic sewage from distributed sewage collection wells into the vacuum tank of the vacuum pumping station, and then uniformly transport it to the sewage treatment terminal through a dedicated sewage pump. The entire system operates in a sealed manner, with no leakage, no odor, and no secondary pollution. It solves the environmental pain points and operation and maintenance problems of the traditional drainage model from the source.

As a mature new generation of sewage collection and treatment technology, vacuum sewage collection systems have now been implemented on a large scale in multiple scenarios. In the field of transportation hubs, the system has been widely used in cruise ships, airports, ship terminals and other scenarios; in the field of cultural preservation and cultural tourism, it is perfectly suitable for special areas with strict requirements on ecological environment and architectural style such as historic streets and cultural tourism scenic spots; in the field of urban and rural construction, it is especially suitable for rural areas, mountain villages, and urban-rural complexes. It is the preferred drainage solution for non-urban planning areas such as Hebu, as well as distributed building areas such as distributed residences and lakeside (sea) villas. It effectively solves the industry's stubborn problems of traditional gravity drainage being difficult to construct in complex terrain and distributed layout scenarios, limited pipe network laying, high operation and maintenance costs, and high pollution risks.

This exchange further deepened the mutual understanding and trust between EPANEL Water Supply and Zhejiang Zero Discharge Urban and Rural Planning. Both parties agreed that vacuum drainage technology meets the current core needs of urban and rural green development, ecological environment protection, and infrastructure upgrading, and has extremely broad market space and development prospects. In the future, the two parties will take this exchange as an opportunity to give full play to their respective core advantages in technology research and development, project resources, and industry accumulation, deepen cooperation, complement each other's advantages, jointly promote the large-scale application of vacuum drainage technology in multiple fields, and inject new momentum into the green upgrading and high-quality development of urban and rural water affairs.

Hefei EPANEL Water Supply Technology Co., Ltd. has always been deeply involved in water supply and drainage, focusing on technological innovation, product development and project implementation of water supply and drainage systems. In the future, the company will continue to polish its core technologies, optimize its full-chain services, and provide the entire industry with integrated water supply and drainage solutions that are more efficient, more environmentally friendly, and more suitable for complex scenarios, and work with industry partners to jointly lead the innovative development of the smart water industry.
