AiS can be used in two main ways. One is to supply water from an independent water source e.g. an emergency tank, tanker, bowser etc, under pressure via another piece of infrastructure, to the user. The other piece of infrastructure might be e.g. a part of the mains system feeding into multiple properties, it could be an individual property like a care home or school, or it may just be a tap bar for filling emergency water containers. Whatever the situation the AiS system can be setup quickly and simply to either maintain or restore supplies to the point at which they are most needed.
The modular nature of the system allows it to be scaled up both in volume and flow to meet even the most demanding requirements.
The image shows a basic independent supply setup, in this case as a planned job the tanks arrived empty and were filled from the main prior to the shut. The AiS unit is set on standby so that when the engineer closes the main the AiS automatically picks up any demand.
Two main types of AiS configuration
Pressure boosted supply
There are many reasons why parts of the network can suffer reduced pressure or intermittent supply conditions, often these relate to temporary changes brought about by maintenance work. When such issues occur they are at best inconvenient and at worst potentially dangerous.
AiS provides a lightweight, rapidly deploy-able solution to low pressure problems by providing a break volume able to manage fluctuations in the mains supply which can then be infused back to the low pressure area. Both the break tanks and the pumps will operate autonomously until normal service can be restored. The system has been shown effective for large volumes over periods of many weeks.
The ability of the AiS units to communicate wirelessly allows systems to be situated across a wide area improving resilliance and providing a more even pressure gradient across the area.
