Design Period means that length of time determined by the sum of the operating life of the solid waste landfill facility plus the postclosure care period necessary to stabilize the waste in the units..
Design period should be greater than lead time.
The decrease in average cost as the size of facility increase is known as economy of scale.
If the economy of scale is small, smaller design period will be used.
It is economical to build a large structure, for longer design period..

Design period is defined as the future period for which a provision is made while planning and designing the water supply programs.
Usually, 15 to 20 years is adopted as design period..

Factors influencing the Design Period
An objective definition of the life cycle of a structure can be described as the number of years in the near future that the structure will be physically & practically suitable for the purpose for which it has been designed.Jan 31, 2023.
a) Availability of funds If funds are not available, one has to keep a smaller design period. b) Interest rates If interest rate is small, a higher value of the design period may be economically possible..
Factors affecting Design Period are given below.
Following are some aspects which act on the Design Period of the structure:
Design period could be defined as the number of years in the near future in which the supply will surpass the demand.
Or, It is the number of years in the near future in which the given facility is obtainable to satisfy the demand.
Why Design Period Is Provided.
It is prodigiously strenuous or unfeasible to produce frequent.
It is the time from the commencement of a project to its completion.
Design period should be greater than lead time.
The decrease in average cost as the size of facility increase is known as economy of scale.
If the economy of scale is small, smaller design period will be used.
It is economical to build a large structure, for longer design period.
But for the projects whose extension is difficult, their design period is kept greater.
For example dams and reservoirs cannot be extended easily.
If the rate of population growth is higher, then for that region shorter design period is required.
It is the time from the commencement of a project to its completion.
Period when an infection is not yet detectable for a given test
