Abstract

The development of West Outer Ring Road, abbreviated as JLLB, to improve the quality of infrastructure in the City of Surabaya. A breakthrough is needed by opening a new existing road section to break down traffic jams that lead to the main corridor section of the central city. The JLLB area, originally a green open area, was converted into a road area. This condition will cause changes in the sum of rainwater runoff that occur. The JLLB also intersects with the railroad tracks. A drainage system plan to ensure no puddles on the road, even through the railroad tracks. The method of this study follows hydrological and hydraulics analysis of the drainage systems. The results of drainage analysis on West Outer Ring Road, abbreviated as JLLB, there are several typical canal dimensions needed. All velocities can be controlled in the range of permissible velocity. The minimum velocity is 0,4 m/sec, and the maximum is 0,873 m/sec. The maximum planned discharge is 1,381 m3/sec. The capacity of boezem is planned to suit 5,104 hr of rain duration. Based on all that results, the drainage analysis of JLLB would be great if implemented according to plan.

Abstract

Indonesians have an average domestic water consumption of 34.2 liters/person/day while the minimum amount to meet basic human needs is 50 liters/person/day. The lack of water consumption requires a water distribution system so that minimum water consumption can be met. Sumberrejo Village is one example that does not have a water distribution network, so to meet daily water needs using ground wells. The use of earthen wells certainly has risks, namely contamination from fecal waste. Research on water distribution network planning needs to be done due to these problems. This plan aims to determine the availability of water to flow through Sumberrejo Village, water needs in the projection year, pipe dimensions, and reservoir dimensions used. This study used a quantitative descriptive method. Hydraulic analysis of piping networks using the Hazen–William method with the Epanet 2.2 auxiliary program. The results of the study found that the availability of water in Sumberrejo Village was inadequate, so it used the Gedang Sutro water source located in Sumberwuluh Village. Water demand in the projection year is 20,966 l / s at peak hour conditions. The diameter of the pipe used in this planning is 8 inches; 6 inches; 5 inches; 4 inches; 3 inches; 2.5 inches; 2 inches; 1.5 inches; 1.25 inches; 1 inch; and 0.75 inches. The reservoir used in this planning is tubular with a diameter of 11.5 m and a height of 4.5 m.
