Sizing

SIZING FOR THE CALCULATION OF POPULATION EQUIVALENTS (P.E.)
Sizing of Grease Traps and Imhoff Tanks, calculation of POPULATION EQUIVALENT.
In residential buildings as well as in production or service activities, it is necessary to evaluate the actual production of sewage
to be disposed of in order to correctly size the Imhoff tanks. Since this is practically impossible, reference
must be made to the number of Population Equivalents (P.E.), a standardized unit of measurement, which can be determined
as follows:
Sizing of concrete Grease Traps and Imhoff Tanks for:
- PRIVATE HOUSING - bedroom count:
1 P.E. for bedrooms with a surface area up to 13.90 sqm
2 P.E. for bedrooms with a surface area exceeding 14 sqm
Sizing of concrete Grease Traps and Imhoff Tanks for:
- HOTELS OR ACCOMMODATION FACILITIES - same as for private housing;
add 1 P.E. for every 6 sqm increase in room surface area beyond 14 sqm;
for holiday homes or special situations where seasonal use allows high occupancy density, it is
appropriate to refer to the maximum actual foreseeable capacity.
Sizing of concrete Grease Traps and Imhoff Tanks for:
- FACTORIES OR CRAFT WORKSHOPS
1 P.E. for every 2 employees, permanent or seasonal, during peak activity.
Sizing of concrete Grease Traps and Imhoff Tanks for:
- COMPANIES, COMMERCIAL OFFICES, SHOPS
1 P.E. for every 3 employees, permanent or seasonal, during peak activity.
Sizing of concrete Grease Traps and Imhoff Tanks for:
- RESTAURANTS AND TRATTORIAS - to calculate the population equivalents, it is necessary to quantify the maximum
seating capacity of the dining rooms, considering that one person occupies approximately 1.20 sqm;
the number of employees is added to the number of customers;
1 P.E. for every 3 people resulting from this sum.
Sizing of concrete Grease Traps and Imhoff Tanks for:
- BARS AND CLUBS - same as the previous point but calculating 1 P.E. for every 7 people.
Sizing of concrete Grease Traps and Imhoff Tanks for:
- CINEMAS, STADIUMS, THEATERS - every thirty users correspond to 1 P.E.
Sizing of concrete Grease Traps and Imhoff Tanks for:
- SCHOOLS AND GYMS - every 10 attendees calculated on the maximum potential capacity corresponds to 1 P.E.
Special cases must be evaluated on a case-by-case basis (contact our technical office).
Note.
After calculating the number of Population Equivalents, it is necessary to check with local competent
authorities (A.R.P.A, Province, HERA) to determine the type of system to be installed.
The water supply to be calculated can vary from 100 L to 250 L for each Population Equivalent, based on
local regulations and the type of activity.
