AquaSPE AG from Zurich Switzerland recently announced access to an open-source wastewater treatment plant design tool and knowledge-sharing community on The Water Network.

AquaSPE CEO Trudi Schifter says wastewater treatment plants are complex, and even getting a traditional activated sludge design can take months and cost tens of thousands of dollars. “This makes it difficult to innovate and compare technologies.”

The Water Network is dedicated to driving the innovation of wastewater treatment solutions, and has announced its new Design Generator tool as a free cloud-based service built for both nontechnical and technical professionals. The tool generates preliminary engineering design documents for conventional activated sludge plants that include an equipment list, process flow and site plan within hours instead of weeks.

Developed over three years by a consortium of experienced design engineering firms, the tool has already helped thousands of utilities, construction companies, city planners, real estate developers and design engineers, according to Schifter.

“We are excited to make this valuable tool available in order to help drive innovation in the water sector,” says Schifter. “We operate the largest network for global water professionals reaching circa 400,000 professionals representing over 10,000 organizations. After extensive research we chose this tool due to the comprehensive analytics and ability to integrate it into our platform in a seamless user-friendly way for our members.”

Ari Raivetz, CEO of, says the industry scope of The Water Network is unparalleled. “The ability to quickly submit a design for a specific population, nutrient removal and geography is critical to provide meaningful results. We are excited that this tool is now available on The Water Network and that plant designers have a place to share their challenges and case studies.”

All organizations with a need for a new or expanded wastewater treatment plant can join the community to discover insights from their peers and run a design on the free service.
