The aim of this study is to derive a new total sediment load formula which is more accurate and which has less application constraints than the well-known formulae of the literature. There are many sediment transport formulas in the literature but most of them are derived from small data sets of natural rivers or experimental designs. Each formulation has its own restrictions, which depends on the original dataset of that study. None of them have gained universal acceptance.To achieve this aim, a wide range of dataset is compiled which includes both experimental lab(flume) data and Natural river data so that a very large range (of parameters) has been achieved. Then this dataset is used to generate a new formula. Five most known total sediment transport formulae, which are approved by American Society of Civil Engineers (ASCE) are used for benchmarking. The dimensionless parameters of these widely used formulae are used as inputs in a new regression approach. The new approach is called Polynomial Best subset regression (PBSR) analysis. The aim of the PBRS analysis is fitting and testing all possible combinations of the input variables and selecting the best subset. All the input variables with their second and third powers are included in the regression to test the possible relation between the explanatory variables and the dependent variable. While selecting the best subset a multistep approach is used that depends on significance values and the Multicollinearity degrees of inputs. Different goodness of fit statistics are used as they represent different perspectives of the model accuracy. After the detailed comparisons are figure out, PBSR is the most accurate equation that is also applicable on both flume and river data.

Water Source protection is one of key aspects in Kosovo and everywhere in the world, concerning latest climate changes, and water demand as well. Seeing from the flood occurred on 2018 at Pusi i Atit wellfield, students including professors approached this problem in order to see possibilities for source protection, not only from floods, but as well from contaminants. Near wellfield is located a stream, actually collecting sewer from the upper part of village and also as a drainage collector. In order to protect the source and inhabitants, samples from the water source has been taken as well from the stream, for chemical and bacteriological analysis, the results will be presented on the paper, including possible protective measures, and stream regulation.

Sediment transport is one of the most powerful factor on river hydrology. It has vital importance for water engineering projects. There are many sediment transport formulas in the literature but most of them are derived from small data sets of natural rivers or experimental designs. Each formulation has its own restrictions, which depends on the original dataset of that study. None of them have gained universal acceptance. As a result, investigation towards the development of more accurate and simpler formulae is still necessary and should be continued.

From 2010 Government of Kosovo, finalized regulations and rules regarding water zone protection. In this regard Regional Water Company Pristina made some steps towards these goals, in order to protect own sources. During 2010 company invested in a design for protection zones and based on this there were construction of RC retaining walls – barrier, towards the road at Lake, Screens at the discharge point from the streams, and finally in 2015-2017 construction of Waste Water Treatment Plant (WWTP) at Mramori. WWTP was constructed on 2016, finalized with sewage network on 2017, under operation and based on results from the samples taken at the inlet and outlet of the Plant we made calculations on Environmental Impact as well cost savings O&M, methodology is based on an assessment towards main parameters.

Application of new technology and “smart” devices is the most well-known experience in all type of works for sustainable services, including water supply networks. Measuring from the distance including online monitoring is one of the easiest way to control flow and pressure on these networks, especially on District Metering Areas (DMA). In order to reduce losses in the network, nowadays, online monitoring and controlling is more than a necessity. Water loss reduction is one of the biggest challenges today in the industry of water treatment. Applying these automatic and electronic devices will be presented below with real measures on site and real examples on Regional Water Company Prishtina service area.
