“…In the flowing stream inside a pipe, the dissolved substances can be conveyed to the pipe wall, where they react with corrosion products and/or with the wall biofilm. The mass transportation of a single substance is described by the advection-dispersion-reaction equation, which is written thus [5]:…”

“…For the inlet node, the tank, the chlorine concentration was considered equal to 0.48 mg/L (the amount that continuously enters the network). In the pipeline editing menu, at "Wall Reaction Coefficient", the obtained values for reaction coefficients at pipe walls were entered, and for the bulk flow decay constant k b the value of -0,85 day -1 was chosen, proposed by [5].…”

The law on drinking water quality aims to protect human health against the effects of any type of contamination by ensuring its quality of clean and health-safe water. Many cases of illness in populations are due to the fact that in their community there is no strict regulation and control regarding the water quality at the source which supplies their water systems. Thus, special importance must be given to the drinking water supply in rural areas, considering that a large part of populated centers within this category do not benefit from centralized drinking water systems. This paper will analyze a small distribution network within a commune in Suceava County. Hydraulic and water quality analysis calculations in the distribution network were performed by means of the EPANET 2.0 software. For the water quality analysis, a surveyed factor was the variation in time of free residual chlorine concentration, this parameter being monitored along with the distribution network (corresponding both to a first order reaction in the fluid volume and at pipe wall, and to a second order reaction within the fluid volume). The hourly water consumption on a working day was considered in compliance with the Romanian standards for villages and rural areas, and the simulation was performed for a period of 72 hours.

In 2021 it is estimated that there are 19,836 people at Universitas Jambi Kampus Pinang Masak Mendalo. One of the most important aspects to support activities in Universitas Jambi Kampus Pinang Masak Mendalo is a clean water supply. This study aims to determine clean water needs, to analyse hydraulic factors such as water discharge, flow speed, water pressure, and head loss using EPANET program, and to calculate the budget required to build a water distribution pipeline system. The results of water distribution pipeline network design are clean water needs at Universitas Jambi Kampus Pinang Masak Mendalo as much as 665,910 liters/day or 18.4975 liters/second and at the maximum daily needs as much as 732,500 liters/day or 20.3472 liters/second in the projected year of 2031. Analyses of hydraulic factors in the pipeline distribution system using EPANET program and manual calculation give the same results, but there are some pipe segments that do not fulfill of flow velocity standard, that are on pipe A1 = 0.15 m/s, B1 = 0.08 m/s dan pipa B2 = 0.25 m/s. The cost required to build a clean water distribution pipeline network at the Universitas Jambi Kampus Pinang Masak Mendalo, is amounting Rp238,252,263.00,-
