Standardized, cost-effective STS prepaid meters and the iSAtech Online STS Vending System enable easy and secure household access to clean drinking water. This allows for the set-up of large, efficient, and cost-effective water supply infrastructures, including online monitoring and mobile payment integration
Efficient and sustainable
The administration process is largely automated and can easily be managed by local staff after a brief introduction. The revenues are collected in a joint administration account. This, in turn, can be used to finance the running costs of the water infrastructure. In pilot projects in Uganda and Tanzania, the STS system has doubled income and minimized expenditure. Savings that make it possible to finance the individual supply of people with clean drinking water in the first place.
Evaluations and reporting can be carried out directly with the iSAtech PayU-Cloud, but connecting external systems such as the mWater Portal is possible.

Consumers do not need smartphones. Using a simple cell phone and mobile payment methods that are used around the globe (e.g., M-Pesa), any desired sum can be transferred to a management account. The iSAtech PayU-Cloud registers the payment, assigns it to the respective consumer, and generates a 16-digit STS credit token, which is sent to the consumer.
The payment system can be integrated in two ways: directly through the Mobile Payment provider or by using the iSAtech SMS Gateway, which forwards instant payment notification SMS to the iSAtech PayU-Cloud for analysis.
