Abstract

Tijaya, 2024 "Study of Environmentally Friendly Drainage as Flood Control in Kaligangsa Village, Margadana District, Tegal City". Pancasakti University Tegal Civil Engineering Thesis Report 2024. Rainwater is very pure water which is almost 100% H2O compound. Rainwater that falls if left to stagnate in the environment or residential areas without any means to absorb and circulate air into the ground, will really disrupt environmental health and will be a problem for residents of the area. Bad community behavior can also affect the capacity of land as a place for air to flow. The method that will be used in this research is a descriptive method, namely a method that explains objective (actual) conditions in a situation that is the object of research. The results of this research show that the flooding that occurred in Kaligangsa, Margadana District, Tegal City was caused by high rainfall intensity accompanied by drainage that was unable to accommodate the existing discharge, with a water catchment area of 0.30 km². In the Planned Discharge, it is obtained (QE)= 1,969 m³/second ≤ (QT)= 7,841 m³/second. So planning for absorption wells is needed. In infiltration wells use concrete buis with dimensions of 0.8 m, 1 m and 1.2 m. It is planned that rainwater enters through gutters and 4" PVC pipes. With 3 types of houses, namely 36/100 m², 45/150 m², 72/200 m. Although not all problems can be solved, these infiltration wells will theoretically help a lot to reduce flooding problems in the environment. Keywords: Drainage, Infiltration Wells, Flood
