Benefits of technology

This patented technology improves on existing systems where an electrically operated water supply source provides power to a wastewater treatment plant. It uses two types of motors - one works better at providing torque while another works poorly when working properly. By utilizing these techniques, this innovative solution allows for efficient operation without requiring expensive maintenance. Additionally, there may have different ways to set up the system based upon specific requirements such as how much liquid should pass through certain parts of the device. Overall, this new approach simplifies the process and reduces costs compared to traditional methods like dredging tunnels underground.

Problems solved by technology

This patented technical problem addressed by this patents relates to how well traditional sewer systems are designed for use with tunneling machines that have small spaces between them or where there may be heavy equipment such as excavators used during construction activities. These areas can collect debris from rainwater runoff along streets while also being exposed to harmful materials like rocks and sand particles. Existing sewers often lack sufficient water removal capabilities due to their size but they don't provide enough area for effective treatment without causing damage when faced with these issues.
