First of all you have to calculate the number of person equivalent (p.e.) in order to know the size of the reed bed you need.

One person equivalent is the organic biodegradable load having a five-day biochemical oxygen demand (BOD5) of 60 gr of oxygen per day.

In the following table you have an indication of how to calculate the number of person equivalent.
(Your local laws may give different indications)

Type of wastewater	Person equivalent
Residential buildings	1 p.e. per person
Hotels	1 p.e. per guest + 1 p.e. every 3 workers
Campings	1 p.e. every 2 guests + 1 p.e. every 3 workers
Restaurants	1 p.e. every 3 table places + 1 p.e. every 3 workers
Cafes	1 p.e. every 10 guests + 1 p.e. every 3 workers
Cinemas, theatres, conference rooms	1 p.e. every 10 sits+ 1 p.e. every 3 workers
