The PPU23WMD is the solution for the management of water supply to domestic or small commercial consumers, and when linked to a pulse output water meter, enables:

• leak and tamper detection,
• management of delinquent customers , and most importantly,
• remote data capture and meter control- Automated Meter Reading (AMR ) with the ability to provide control, which is the essence of Advanced Metering Infrastructure ( AMI).

• dispense a fixed daily quantity of water, thereby providing the ability to limit a consumer to a finite ( or pre-negotiated ) level of supply. This is especially useful in the case of low income consumers who may never be able to afford to pay for water, but nonetheless have the right to be provided with at least a basic level of service
• be linked to a fixed( flat rate ) tariff , so as to provide consumers the option to voluntarily limit consumption according to their budget. As with the free basic water allocation, this facilitates budgeting.
• provide meter readings by the radio signal to a drive or walk by collector- AMR or AMI
• be shut off remotely, or operate at reduced daily or monthly quantity. This is very useful in managing delinquent customers.
• default to a trickle flow if required, once the full pressure allowance has been consumed. Trickle flow will be appoximately 1 litre per hour.

Benefits to the Service Provider

The WMD offers financial and operational benefits to the service provider:

Financial benefits

• Low cost of acquisition
• Prevents wastage and loss of treated potable treated water
• Reduces consumption by up to 80%, yet allows some consumers the minimum lifeline quantity
• Capital recovery possible within 6 to 10 months

Operational benefits

• Dispenses a fixed daily amount of water , from 10 litres per day to 50 000 litres per day , at full pressure.
• Accurate water balancing across a zone using synchronised meter readings
• In-field programming, testing, and interrogation
• Automatic Meter Reading (AMR) option allows interrogation via radio link
• Automatic Metering Infrastructure (AMI) option allows
• parameter configuration and data collection via radio link
• efficient disconnection/reconnection of supply
• Radio link receiver can be vehicle-mounted or carried by personnel

Benefits to the Consumer

• Consumers can budget their daily or monthly consumption through capped daily and/or monthly allowance
• Consumers cannot over-use or over-spend their budget.
• Daily or monthly carry over where service providers allow it
• Accumulation of unused daily allowance which encourages responsible water usage
