Those of you
who are already aware of the costs involved in running a urinal
will know that vast savings can be made by fitting a flow controller.
In our area, one uncontrolled urinal cistern could cost around
400 ukp per year. Fitted with a controller, this could drop
to 65 ukp per year! Multiply these savings by the number
of cisterns in your establishment, and these are very significant.

How it works
Upon installation, the unit is taught the time taken to fill the
cistern. By sensing the presence of people with its infra-red 'eye',
the urinal controller only allows the system to fill for that time
when it has been used, and can also be programmed to limit the interval
between flushes to a pre-determined time. During long periods
of non use, the unit provides a 'hygiene' flush at twelve
hourly intervals to keeps the traps fresh.
The idea of controlling costs in this way is not a new one, but
this product has many good features -
- Can be fitted by anyone with basic handyman tools and skills.
No need for plumbers or electricians.
- Battery operated, so completely safe for use in the washroom
area. Battery life in excess of eighteen months using
standard 'AA' 1.5V batteries.
- Low battery warning light which will flash for days before
the batteries are exhausted.
- Works with a range of standard valves from multiple manufacturers.
- Unlike some other products, does not forget its program when
the batteries are exhausted, and will continue to work after
changing without any re-programming.
- Retains program for years without battery power.
- Pays for itself (including installation) within six months.
- If waste pipe becomes blocked, damage to unattended buildings
is minimised due to flushing only every 12 hours.

Example
calculation.
The cost of water in our area is about 0.98 pounds per cubic metre,
so, if we take eight litres of water 6 times an hour for twenty
four hours a day, every day, we get
Six flushes an hour = 6 x 24 = 144 flushes per day
7 days per week = 7 x 144 = 1008 flushes per week.
Fifty two weeks per year = 1008 x 52 = 52416 flushes per year.
Multiply 52416 flushes by eight litres to get 419328 litres (419
cubic metres) of water every year, which would cost about 411 pounds.
So, with a Urinal Flow Controller installed in an office
occupied Monday to Friday, 08:00-18:00 with a twenty minute 'delay'
time, we get
Three flushes an hour for ten hours of the day = 30 flushes
per day
Plus one hygiene flush = 31 flushes per day
for five days a week = 155 flushes per week
Plus four hygiene flushes over the weekend = 159 flushes per
week
Fifty two weeks per year = 159 x 52 = 8268 flushes per year
Multiply 8268 flushes by eight litres to get 66144 litres (66 cubic
metres) of water every year, which would cost only 65 pounds!
