Simulation Results

The clean water distribution in the Genteng Subdistrict, Banyuwangi Regency is included in the service area of the Zone 1 PDAM tile unit. The 60 liters/second reservoir discharge capacity is obtained from Sumber Umbul Sari in the Glenmore District. The distribution of clean water in Zone 1 is still less than 70% of the area served, as the installed discharge capacity is estimated to be insufficient. In order to achieve the distribution goal, a network system must be developed by adding direct debits and planning a new pipeline. The Epanet 2.0 program simplifies the calculation of pipeline networks by integrating elevation data, network maps, pipeline specification, and load. The analysis of the simulation results was conducted using the Public Works Minister's hydraulic parameter standards 2007. Planning of a distribution network and a cost budget in 2029 were done to estimate the water supply needs and budgets required. The hydraulic simulation results based on the analysis of the pressure of all joints are in accordance with the standard, while the analysis of the velocity in pipe is less standard. The need for water discharge in 2029 is 71.6 liters/second. In Kembiritan Village, the construction of distribution pipes with an additional reservoir unit was planned. The planned pipe dimensions in the development area were 25 mm at 796 meters, 50 mm at 4062 meters, and 75 mm at 1518 meters. The cost of planning a clean water distribution system in 2029 is Rp. 1,431,375,000.00. Distribusi air bersih di Kecamatan Genteng Kabupaten Banyuwangi merupakan wilayah pelayanan Zona 1 PDAM unit Genteng. Kapasitas debit reservoir sebesar 60 liter/detik berasal dari sumber umbul sari di Kecamatan Glenmore. Pendistribusian air bersih di wilayah Zona 1 masih kurang dari 70% wilayah yang terlayani, karena diperkirakan kapasitas debit yang terpasang kurang mencukupi. Untuk memenuhi target pemerataan distribusi perlu pengembangan sistem jaringan dengan penambahan debit dan perencanaan jaringan pipa baru. Program Epanet 2.0 memudahkan dalam perhitungan jaringan perpipaan dengan mengintegrasi data elevasi, peta jaringan, spesifikasi pipa dan debit. Analisis hasil simulasi menggunakan standar parameter hidrolis Permen PU 2007. Perencanaan pengembangan jaringan distribusi dan anggaran biaya pada tahun 2029 guna memperkirakan debit kebutuhan air dan anggaran biaya yang dibutuhkan. Hasil simulasi hidrolis berdasarkan analisis tekanan semua junction telah sesuai standar, sedangkan analisis kecepatan masih di bawah standar. Kebutuhan debit air tahun 2029 sebesar 71,6 Liter/detik. Pengembangan pipa distribusi direncanakan di Desa Kembiritan dengan tambahan satu unit reservoir. Dimensi pipa rencana di wilayah pengembangan digunakan diameter 25 mm sepanjang 796 m, diameter 50 mm sepanjang 4062 m dan diameter 75 mm sepanjang 1518 m. Biaya perencanaan sistem distribusi air bersih tahun 2029 sebesar Rp. 1.431.375.000,00.

Losses of water due to leakage occur in every distribution network, the only difference is in the amount of leakage. The leakage levels are relatively high in cities of developing Asian countries. Among the several factors, operating pressure is the most important affecting the leakage. This paper describes how the management of pressure can help reduce the leakage in the water distribution network. EPANET is used to develop the hydraulic model to analyse the effect of alternative pressure profiles on the leakage in a pilot area within the water distribution system of Bangkok. One of the alternatives is implemented in the field to verify the applicability of the model. Results indicate that the average reduction in pressure by 2.4 m can reduce the leakage by 12.5% of the system inflow without compromising the level of service.

Potable Water Quality

Abstract. Abnormalities in hydraulic conditions inside a water distribution network are strongly related to the deterioration of potable water quality. Leaking pipes and valves, for instance, cause changes in water hydraulic conditions and may allow the entry of microbes to the distribution system. Flow and pressure shocks can detach soft deposits and biofilms from the pipe surface which is shown among others as the elevated concentrations of bacteria, metals and turbidity in water. On that account, monitoring the hydraulic conditions in a distribution network and utilizing this information in developing a predictive water quality model assists providing a sufficient amount of potable water with an appropriate quality for the consumers use. In this paper, the water quality at the end part of the district metered area is modelled based on only the water flow and pressure measurements along the distribution network. The developed model can be utilized in proactive operation as it is able to show the potable water quality hours in advance before it is discovered at the end part of the distribution network.

Heterotrophic Plate Counts

An area of a distribution network receiving organically rich treated water was studied for a period of one year to gain further understanding of the regrowth of bacteria in a water distribution network. These bacteria are considered to be harmless to man. Surveys additional to this study confirmed that enteroviruses and pathogenic bacteria (as defined by EC directives) were absent, consistent with the general absence of coliforms. Fixed points were sampled regularly for bacteriological analysis and for relevant physical and chemical parameters. Heterotrophic plate counts were carried out using standard methods and a study was conducted to test alternative techniques. It was found that bacterial regrowth occurred close to the treatment works and longer retention resulted in little increase in plate counts. Monochloramine residuals of 0.26mg/l or less did not prevent regrowth. The assimilable organic carbon concentration decreased through the distribution system and increased following booster chlorination. Plate counts showed a seasonal pattern peaking in the spring and autumn and decreasing in the summer and winter. The predominant genera of bacteria were Pseudomonas, Alcaligenes and Aeromonas with maximum counts of 17,000, 23,000 and 1,700 CFU/ml respectively. Heterotrophic plate counts using the R2A medium, spread plate method and 7 day incubation period were on average 190 times greater than counts using the UK standard method. The increase in count gained by using the alternative method was greatest at the sampling points furthest from the treatment works.

Dead End

It is difficult to estimate residual chlorine at the dead-end area of the water distribution network because chlorine consumption is influenced by various factors. Therefore, there are many water utilities that control the amounts of chlorine in reservoirs using empirical trial-and-error methods to maintain safe levels of residual chlorine in the distribution system. In this study, an ANN model of residual chlorine concentration is proposed which could be used to reduce in chlorine use in water distribution system. The ANN model with best performance was selected by training and verification. The five scenarios for the reduction in chlorine use were analyzed by setting the input chlorine as low as 0.05~0.25 mg/L compared with the input chlorine observed in the time series. Case 4 is the best to be satisfied with the input condition (0.4 mg/L or more) and output condition (0.34 mg/L or more) at the same time. It is possible to reduce chlorine in use up to 0.2 mg/L in the maximum amount.

Proposed Model

Distribution networks are an essential part of all water supply systems. Distribution system costs within any water supply scheme may be equal to or greater than 60% of the entire cost of the project. The reliability of supply is much greater in the case of looped networks. The pipe networks have concentrated outflows or uniform outflow along the length of each pipe. In some pipes with variable discharge of a looped distribution network, water velocity could be reversed between its extremities. Thus, it is a water stall point denominated neutral point in which the discharge is null. In this paper a mathematical model for the determination of water stall point location in the pipes with distributed consumption is developed. This model has been implemented in a computer program for PC microsystems. Numerical example will be presented to demonstrate the accuracy and efficiency of the proposed model.
