Land use change occurs in many cities in Indonesia. Population growth causes the expansion of residential area. Without proper planning and design, the development of residential area can increase the runoff volume. The objective of this study is to provide an eco-drainage system design for real estate in Indonesia to minimize the possible increased runoff.The study area in this paper is a bare area of 14,602.26 m2 in Mojokerto Regency, East Java, Indonesia which is planned to be developed into real estate. The design of eco-drainage system consists of installation of 4400 litre of rainwater storage tank and a 1200 m3 of retention pond. The analysis includes the estimation of peak discharge of the selected area using the Rational formula and estimation of evapotranspiration in the retention pond using Thornthwaite method. The result of the analysis shows that 50.2 m2 of roof surface can capture rainwater varies from 0.04 – 18.4 m3/month. The water is used to fulfil the household water needs in the real estate such as for sanitation & waste disposal, gardening, personal washing, cleaning home, and washing clothes along the year except in August and September. While overflow of the tank occurs in January, February, and March. The excess rainfall, which is not captured, flows to the retention pond. It is used for watering public garden using a sprinkling water system. The combination of chosen dimension of storage tank and retention pond can reduce the runoff volume minimum by 48.19% in February in the study area.The proposed design still cannot accommodate all excess rainfall due to the transformation of a bare land into real estate. Therefore, it is recommended to consider another utilization of water in the retention pond.

Since removal and disposal of sustainable urban drainage system (SUDS) sediment can incur high maintenance costs, assessments of sediment volumes, quality and frequency of removal are required. Sediment depth and quality were surveyed annually from 1999–2003 in three ponds and one wetland in Dunfermline, Scotland, UK. Highest sediment accumulation occurred in Halbeath Pond, in the most developed watershed and with no surface water management train. From comparison of measured potentially toxic metal concentrations (Cd, Cr, Cu, Fe, Ni, Pb, Zn) with standards, the average sediment quality should not impair aquatic ecosystems. 72–84% of the metal flux into the SUDS was estimated to be associated with coarse sediment (>500 μm diameter) suggesting that management of coarse sediment is particularly important at this site. The timing of sediment removal for these SUDS is expected to be determined by loss of storage volume, rather than by accumulation of contaminants. If sediment removal occurs when 25% of the SUDS storage volume has infilled, it would be required after 17 years in Halbeath Pond, but only after 98 years in Linburn Pond (which has upstream detention basins). From the quality measurements, sediment disposal should be acceptable on adjacent land within the boundaries of the SUDS studied.

Tarakan City is one city that is often flooded during the rainy season it is in because of the narrow drainage system and due to the accumulation of garbage other than one of the factors that affect flooding is tidal. For the central Tarakan Region, specifically in the region of Karang Anyar Central Tarakan that is Seroja , Kenanga and mawar street flood that occurred due to the drainage system which is not good. And population growth is rapidly increasing and the growth of residential construction and industry as well as other supporting facilities are not balanced with the development of the drainage system. Increase the number of discharges that come out due to the increase of housing and other buildings are often already do not meet the capacity of its maximum capacity on existing drainage channels. The research is conducted by doing a survey in the field to obtain primary data and secondary data which will then be processed using the method ISO No. 03- 2459-2002 about general and technical requirments infiltration wells, this standard is a revision of ISO No. 03-3459-2991.

Pollution Impacts

For upgrading the urban drainage system (UDS) the reduction of pollution impacts is the priority task concerning the environmental protection of the receiving waters. With simulation models the interactions between surface, sewer systems, overflow structures and treatment facilities within the UDS can be shown. Models to simulate the pollutant impacts, transport and the effects on the receiving waters are available. In a first step a pollutant transport model of sewer systems and a model to simulate the wastewater treatment processes are connected. With these models the efficiency of upgrading measures can be checked in all parts of urban drainage systems.

Non Linear Systems

Conventional UDS models are mechanistic which though appropriate for design purposes are less well suited to real-time control because they are slow running, difficult to calibrate, difficult to re-calibrate in real time and have trouble handling noisy data. At Salford University a novel hybrid of dynamic and empirical modelling has been developed, to combine the speed of the empirical model with the ability to simulate complex and non-linear systems of the mechanistic/dynamic models. This paper details the ‘knowledge acquisition module’ software and how it has been applied to construct a model of a large urban drainage system. The paper goes on to detail how the model has been linked with real-time radar data inputs from the MARS c-band radar.

Urban Drainage System

All the parts of an urban drainage system, i.e. the sewer system, the wastewater treatment plant (WWTP) and the river, should be integrated into one single model to assess the performance of the overall system and for the development of design and control strategies assisting in its sustainable and cost effective management. Existing models for the individual components of the system have to be merged in order to develop the integrated tool. One of the problems arising from this methodology is the incompatibility of state variables, processes and parameters used in the different modelling approaches. Optimisation of an urban drainage system, and of the wastewater treatment process in particular, requires a good knowledge of the wastewater composition. As important transformations take place between the emission from the household and the arrival at the treatment facility, sewer models should include these transformations in the sewer system. At present, however, research is still needed in order to increase our knowledge of these in-sewer processes. A comparison of the state variables, processes and parameters has been carried out in both sewer models (SMs) and activated sludge models (ASMs). An ASM approach is used for the description of reactions in sewer models. However, a difference is found in the expression for organic material (expressed in terms of BOD) and heterotrophic biomass is absent as a state variable, resulting in differences in processes and parameters. Reconciliation of both the models seems worthwhile and a preliminary solution is suggested in this paper.

Overland Flow Model

Dual urban drainage models allow users to simulate pluvial urban flooding by analysing the interaction between the sewer network (minor drainage system) and the overland flow (major drainage system). This work presents a free distribution dual drainage model linking the models Iber and Storm Water Management Model (SWMM), which are a 2D overland flow model and a 1D sewer network model, respectively. The linking methodology consists in a step by step calling process from Iber to a Dynamic-link Library (DLL) that contains the functions in which the SWMM code is split. The work involves the validation of the model in a simplified urban street, in a full-scale urban drainage physical model and in a real urban settlement. The three study cases have been carefully chosen to show and validate the main capabilities of the model. Therefore, the model is developed as a tool that considers the main hydrological and hydraulic processes during a rainfall event in an urban basin, allowing the user to plan, evaluate and design new or existing urban drainage systems in a realistic way.
