What problems could arise due to improper drainage?

Improper drainage can lead to water accumulation, resulting in flooding and soil erosion, which can damage infrastructure and crops. It can also create conditions for mold and mildew growth, posing health risks to residents. Additionally, stagnant water can become a breeding ground for pests like mosquitoes, increasing the risk of disease transmission. Long-term, inadequate drainage may compromise groundwater quality and contribute to sedimentation in waterways.
