Abstract

Water stored on the surface generally turns into runoff and much faster than groundwater considering the very low flow rate of the latter. Drainage of the Pondok Jati residential area is less able to receive or accommodate rainwater discharge because the development and growth of a city is one of the triggers for increasing the volume of discharge that passes through the residential area. Land use will affect the percentage of water that seeps into the soil with surface flow. Land with dense populations and many buildings, infiltration wells must be made more and larger in volume. Either with individual infiltration wells or with infiltration wells collectively for several houses, the need for infiltration wells from each block to reduce runoff that occurs with a 10-year return period plan. For the specifications of this infiltration well, concrete pipes are used. This infiltration well itself has concrete pipe walls with a diameter of 100 cm (1 meter) with the depth of the infiltration well is 300 cm (3.0 meters) and the number of points needed. The cost of making an infiltration well with a total of 210 infiltration wells in the Pondok Jati Sidoarjo housing complex is Rp. 696.358.600,- .

Abstract

The Pondok Jati housing complex is less able to receive or accommodate rainwater discharge due to changes in channel dimensions, shallowing of channels, and dirt due to waste from people who do not care about the local environment. To anticipate this, it is necessary to repair and build infrastructure that functions as a flood controller according to the characteristics and conditions of the location. Efforts made for this are to redesign drainage at low cost. Hydrology and Hydraulics methods are applied to obtain a 5-year planned discharge and existing channel discharge, to plan channels with a 5-year planned return period. The existing channel discharge for the Pondok Jati housing complex is obtained as much as 0.450 m3/sec, and modeling is carried out in accordance with SNI 02-2406-1991: Procedures for general planning of urban drainage. With the redesign, the planned channel dimensions are obtained measuring 0.50 m x 0.75 m, in the form of a square without a cover.
