Technology category:   Water Quality

Solution

Aclarity commercializes novel electrochemical water treatment systems for the complete, on-site destruction of contaminants like PFAS in wastewater.

Why this matters

PFAS, a group of manufacturing chemicals that is known to be harmful to the environment and human health, commonly enters the environment from wastewater discharge and landfill leachate. Alacrity’s system treats the water that drains from landfills and destroys the PFAS before it can enter the environment and cause harm.

BlueConduit platform provides clarity, recommended order for lead service line replacements, and easy-to-understand dashboards for internal and public consumption, empowering utilities and individuals with information to reduce their exposure to lead.

Why this matters

Lead pipes were the building blocks of the modern day water distribution system. However, now lead exposure has been linked to detrimental health effects on humans including children’s development. BlueConduit’s software optimizes the lead service line replacement process through accurately predicting lead conveyance pipes locations that cities can use in decision making.

Technology category:   Sanitation

Solution

Instead of flushing waste, CHANGE: WATER Labs is solving the problem of off-line sanitation with a toilet that evaporates it. Instead of using and polluting water to get rid of waste, their iThrone solution turns waste back into pure water.

Why this matters

Millions of people across the developing world live beyond the pipe – without access to basic drinking water and sanitation services. This is because new centralized drinking water and sewage systems are unsustainable, infeasible and costly to build. change:WATER Labs provides a decentralized sanitation solution that hygienically contains waste to reduce disease and prevent sewage runoff into nearby water bodies.

DigitalPaani is a lifecycle management system that leverages proprietary software, live data, and automation to optimize every aspect of plant operations, be it diagnosing problems early, managing the workflows of every individual involved in operations as per actual plant design, guiding real-time process troubleshooting, and recommending retrofits when needed.

Why this matters

While cities in India are focused on installing more water distribution and treatment plants, they lack operational efficiency tools, leading to the inability to handle complex operations and prevent the discharge of untreated effluent into surrounding water. DigitalPaani’s IoT system improves plant management through not only identifying problems, but also by recommending changes in operating parameters, training and guiding every task executed by the operations team.

Solution

Gross-Wen Technologie’s (GWT) patented revolving algae biofilm (RAB) system cost effectively and sustainably uses algae-based treatment to remove nutrients, capture carbon dioxide and produce a sellable algae byproduct.

Why this matters

Anaerobic digesters break down solid waste during the wastewater treatment process. When treating the solid waste digestate, these systems release biogas which is high in GHG’s like carbon dioxide and methane. However, GWT’s cost-effective system reduces the amount of carbon in biogas released, making their technology much more sustainable than alternative solutions.

Solution

SewerAI leverages its cloud inspection management platform (Pioneer™) and AI Computer Vision tools (AutoCode™) to help wastewater professionals to accelerate productivity, increase condition assessment accuracy, and reduce the overall cost to maintain and renew aging collection systems.

Why this matters

Limited insight into the conditions of sewer pipes combined with aging and overworked infrastructure increasingly leads to unexpected sewer collapses and overflow events that affect residential neighborhoods and marine life alike. SewerAI’s software enables municipalities to assess the condition of buried wastewater assets, predict likely failures, and optimally prioritize the rehabilitation or replacement of their assets.
