The purpose of having adequate slopes in drainage systems primarily revolves around preventing the pooling of water. Proper slopes are essential in ensuring that water flows away from areas where it can accumulate, thus minimizing risks associated with standing water. This is particularly important in food processing and handling environments, where stagnant water can become a breeding ground for pathogens and contribute to unsanitary conditions. By directing water efficiently through the drainage system, adequate slopes help maintain hygiene and safety standards, which are critical in facilities subject to health regulations.

Other options, while they might have some relevance, do not address the most critical function of drainage slopes. The aesthetic appeal or ease of cleaning does not directly impact the operational efficacy of drainage systems, and while material costs are a factor in design, they are less significant compared to the functional necessity of preventing water pooling.
