Transforming Septic Tanks into "Next-Generation Water Infrastructure" with Digital Power
Nocnum Co., Ltd. has released "AquaLink," an IoT x AI system for septic tanks. This system aims to transform septic tanks into smart water infrastructure by visualizing water quality and estimating water quality parameters using AI models. Pre-orders for a paid service will begin in late May 2026, addressing the challenges of labor shortages in septic tank management.

Nocnum Co., Ltd. (Headquarters: Aichi Prefecture, Representative: Miki Omori) has for the first time released "AquaLink," an IoT x AI system that evolves septic tanks, which are small-scale wastewater treatment facilities, into "smart water infrastructure" for the coming era.
Pre-orders for a paid service will commence around late May 2026.
## About the Early Paid Offering
In the initial phase, we will work with adopting companies and local governments to build an implementation and operation system that aligns with actual on-site operations. We will also improve our services and enhance AI capabilities through data and case studies obtained from collaboration with these companies and local governments.
## What is AquaLink?
AquaLink is a decentralized water infrastructure platform that combines IoT sensors to "visualize" water quality and AI.
The sensors installed in septic tanks continuously measure water quality and microbial activity within the tank, visualizing daily changes and signs of abnormalities as graphs on the cloud.
This enables:
- Early detection of abnormalities
- Support for management decisions
- Streamlining inspection tasks
- Enhancement of data-driven explanations
### Effluent Water Quality Estimation Model
AquaLink implements an AI model that estimates water quality parameters based on acquired sensor data.
Currently, the following water quality indicators can already be estimated and numerically output:
- Transparency
- BOD concentration
- Total Nitrogen concentration (TN)
- Ammonia Nitrogen (NH₄-N)
Furthermore, model development is currently underway for the following items:
- Nitrite Nitrogen (NO₂-N)
- Residual Chlorine, etc.
Through this, we aim to realize a new management method that allows continuous and non-contact monitoring of water quality information, which traditionally required on-site sampling and analysis.
AquaLink aims to realize next-generation septic tank management that supports on-site operations with AI and enables data-driven decision-making.
### Background: Continued Demand for Septic Tanks and the Challenge of Labor Shortages
Over 4 million septic tanks are installed nationwide, serving as crucial infrastructure supporting local water environments and sanitation. Against the backdrop of population decline and increasing sewage maintenance costs, the importance of decentralized wastewater treatment is expected to continue.
On the other hand, concerns about future labor shortages are rising due to the aging of septic tank managers and a decrease in young entrants. To maintain and improve management quality with limited personnel, the development of a digital foundation to support on-site operations is required.
