Why is proper design important for a collection system?

Proper design is crucial for a collection system primarily to ensure it can handle peak flow conditions without overflow. During periods of high rainfall, snowmelt, or other peak flow events, a well-designed system accommodates increased water flow effectively. This prevents situations where the system might exceed its capacity, which can lead to overflows and subsequent environmental issues, such as pollution or damage to public health by contaminating surrounding areas with untreated wastewater.

Furthermore, a robust design helps maintain appropriate hydraulic performance, ensuring that all components of the system, such as pipes and pumps, function optimally under varying conditions. This not only ensures compliance with regulatory requirements but also prolongs the lifespan of the infrastructure by avoiding excessive stress that could lead to failures or costly repairs in the future. Proper design ultimately safeguards public health and environmental integrity by proactively managing flow conditions.
