What needs to be evaluated in drainage systems to accommodate increased demand?

In evaluating drainage systems to accommodate increased demand, it is essential to assess their suitability. This involves determining whether the existing drainage system can handle the anticipated increase in flow or whether modifications are required to meet the demands effectively. Suitability encompasses various factors such as the capacity of the system, the potential for blockages, and whether the infrastructure can handle a greater influx of water during peak times.

Considering suitability means looking at how well the current system functions under the additional strain and if it is designed to meet modern standards and regulations. It also covers the adaptability of the drainage system to changing conditions, like increased rainfall or urban development, ensuring efficient and effective management of wastewater and stormwater.

While layout and design, material used, and installation procedures are all important elements in the overall effectiveness of a drainage system, the immediate focus in accommodating increased demand lies in assessing whether the system is capable of managing the changes expected. Therefore, the most relevant factor to evaluate is indeed the system's suitability.
