Study on Raw Water Needs at Cibanten Reservoir Serang Regency, Banten Province
Keywords:clean water; embung;, discharge;, cibanten, ciomas
The rural communities of Sukadana and Sukabares in Serang Regency, Banten Province, require clean and quality water. Current water supply of 10 liters per second serves 4,120 people in Sukadana and 500 in Sukabares. Yet, many lack access due to a required flow rate of 21 liters per second for the combined 9,399 population. Additionally, the existing water network is aging and functioning suboptimally due to damage and insufficient volume capacity. Two main reasons, the damaged old network and insufficient water volume supply, necessitate the construction of a new water network by revamping the existing system and enhancing the reservoir capacity. This network planning is designed to serve the community for the next 22 years, aiming toward Indonesia's golden age in 2045. To ensure the provision of clean water, a well-structured Raw Water Network Development is required. A sound network involves meticulous calculations of water demand and availability to formulate an appropriate Water Network System. The study utilizes measurements from a Current Meter at the Cibanten Reservoir and the FJ. Mock method for establishing reliable flow rates. Water demand calculations are based on population growth projections using arithmetic, geometric, and exponential methods, extended to the year 2045. The research indicates that by 2045, the new network will cater to 15,952 individuals, with a required flow rate of 36 liters per second. This will serve domestic households at 20.30 liters per second, social activities at 1.11 liters per second, and non-domestic purposes at 3.86 liters per second, resulting in a total demand of 35.38 liters per second, considering water loss due to evapotranspiration. The available drinking water flow is abundant at 272 liters per second. With the development and improvement of the Clean Water System, this water supply will be sufficient to meet the consumption needs of the communities in Sukadana and Sukabares in the Ciomas sub-district of Serang Regency, Banten Province. Furthermore, the Cibanten Reservoir serves an additional purpose by irrigating 159 hectares of rice fields in Sukadana Village at approximately 87 liters per second, as well as supporting tourism in Serang Regency and the broader Banten Province. The challenge of the Clean Water Network System is being addressed through the construction of this system by the Ministry of Public Works and Housing, Directorate General of Water Resources, SNVT Groundwater and Raw Water, and the Cidanau-Ciujung-Cidurian River Basin Agency, Banten Province.
