result. The conventional system gets all of the stormwater runoff to the end of
the sewer piping as quickly as possible, while it is the intent of the conservation
design system to reduce almost all of the runoff to zero and have the storm
sewers function as linear infiltration trenches (Figure 4-5).
Guideline 4: Design with Operation and Maintenance in Mind
Every engineering design begins with a basic method that is applied to solve
a given problem, with new (or rediscovered) materials developed to implement
