7.1 Product description
AQtap
AQtap is an intelligent water dispenser that addresses some of
the main challenges of providing a reliable and sustainable water
supply in the developing world. Through an integrated platform
for revenue collection and online management of water points,
AQtap supports the financial viability and accountability of water
service operation.
AQtap supports user friendly dispensing of drinking water to
consumers through a simple and intuitive interface and system
for credit transactions using smart cards.
Consumers load credits directly at the AQtap onto their
WaterCards, either through local water credit vendors or via
mobile credit platforms.
When tapping water, the water credits of the consumers'
WaterCard are automatically deducted in a transparent way.
The water dispenser has a robust construction, it operates
precisely and with minimum wastage of water. The AQtap can be
operated with grid and / or solar power. The internal battery is
used as a backup power for approximately 12 hours of operation
with 250 tappings.
aqTOP
aqTOP is a terminal for water credit distribution and smart card
activation. aqTOP can be used as a supplement in large water
kiosks and mini grid applications (multiple dispensers) to avoid
that the credit distribution disturbs the water tapping.
Water Management System
The Water Management System (WMS) is an online platform that
monitors and manages connected AQtap water dispensers.
Smart cards
Smart cards are required for all actions at the AQtap. Four user
profiles are available for different actions.

7.1.1 Power supply
The AQtap can be operated with grid and / or solar power. It uses
the power supply in the following hierarchy:
1. solar power
2. grid power
3. battery.
Using solar power requires a connected battery. The internal
battery is loaded when grid or solar power is available, and is
used as backup power for approximately 12 hours of operation,
assuming 250 tappings of 20 l at a flow rate of 25 l/min and idle
time between the tappings.
After discharging the backup battery, tapping water will not be
possible right away when power (solar radiation) is on again, until
the battery is recharged. A discharged battery takes 12-14 hours
of constant grid supply to be recharged. If water is tapped while
recharging, it may take longer. If the internal battery is not
powerful enough, it can be substituted by an external battery with
MPPT charger.
See section Power supply requirements.
7.1.2 Water supply
The water supply must provide clean drinking water. See
section Water supply requirements.
7.2 Applications
7.2.1 Intended use
• The AQtap is intended for dispensing drinking water and
handling the smart cards for various actions. The quality of the
dispensed water must comply with the drinking water
standards of the WHO.
• The aqTOP is intended for handling the smart cards for
various actions, it does not include the hydraulic part.
• The AQtap / aqTOP interface is intended to be operated with
fingers and smart cards only.
• The smart cards are intended for handling water credits and
accessing the AQtap functions according to the different rights
of the smart card holders.
Observe the technical data specified in section 13. Technical
data.
7.2.2 Improper use
The operational safety of the product is only guaranteed, if it is
used in accordance with section 7.2.1 Intended use.
• The AQtap must not be used for other media than drinking
water.
• The AQtap interface must not be operated or treated with any
kind of tools or items.
• The AQtap must not be used if it is damaged, after improper
repair or after unauthorized modification.
Note
The internal battery is a wear part. If the external
power supply is insufficient or instable, the battery is
often completely discharged and used in a low state
of charge. As a consequence the battery can be worn
out within a few weeks.
Note
Depending on the solar radiation and degree of
AQtap utilization, the internal battery and charging
with solar power can be insufficient.
In cases where tapping is not possible after using the
backup battery, an external battery with MPPT solar
charger can be used.
DANGER
POISONING
Improper use can lead to personal injury!
The AQtap dispenser must be used with water
complying with WHO drinking water standards.
All parts and materials used in the hydraulic system
must be suitable for drinking water appliances.
Caution

7.4 AQtap safety concept
AQtap water dispensers are provided with a number of safety
measures to avoid misuse by invalid smart cards or keys:
• Each AQtap is delivered with a pair of unique keys for the
cabinet. Spare keys cannot be purchased. We recommend to
keep one key as a master for copies in a safe place.
• The AQtap owner receives three smart cards that are
preassigned to the proprietary WMS group: two AdminCards
and one ServiceCard.
• All further smart cards must be ordered separately and
activated at the AQtap.
• Smart cards can be used at all AQtaps within their group.
Smart cards assigned to a group cannot be used within
another group.
• AdminCards and ServiceCards are code-protected. The code
must be set at the AQtap when the cards are used for the first
time. The set code cannot be changed afterwards.
• All smart cards can be blocked permanently via WMS.
7.5 Overview of components and connections
The AQtap components are connected through different
communication technologies making it possible to exchange data
between the involved components.
All transactions between smart cards are carried out directly at
