Infiltration of stormwater most commonly occurs due to which factor?

• A. Faulty house sewers
• B. Proper drainage design
• C. Residential sump pumps
• D. Routine sewer cleaning

Answer: (A)

Infiltration of stormwater primarily occurs due to faulty house sewers. Faulty house sewers can create pathways for groundwater and stormwater to enter the sanitary sewer system. This can happen through cracks, broken pipes, or improper connections, which allow water to seep into the sewer lines. When stormwater infiltrates these compromised systems, it can lead to overloading of the treatment plants and increase the risk of wastewater overflow or contamination. Proper drainage design, residential sump pumps, and routine sewer cleaning do not facilitate the unwanted inflow of stormwater into the sewer system. In fact, proper drainage design aims to manage stormwater effectively and reduce runoff, whereas sump pumps are typically used to redirect excess water away from foundations, rather than directing it into the sewer system. Routine sewer cleaning is performed to maintain the integrity of the sewer system, preventing blockages and ensuring that it functions properly, which also helps to mitigate infiltration issues.
