Washington, D.C. operates one of the oldest combined sewer systems in the country. In neighborhoods like Capitol Hill, Georgetown, and Shaw, your sanitary waste shares the same pipes with stormwater runoff. When thunderstorms dump two inches of rain in an hour, the system cannot handle the volume. Pressure builds in the collection network and forces sewage back through the lowest drain openings in your home. Basement floor drains become eruption points. This problem intensifies during summer storm season when D.C. averages four to six high-intensity rainfall events per month. Severe drain blockage clearing becomes critical because any restriction in your private lateral reduces the system's ability to relieve pressure. Main sewer line clog repair prevents your home from becoming the path of least resistance when the combined system overflows.
