Considered the most frequently used sources of autonomous water supply of a country house – manhole and well. It is shown that the chemical composition of natural water in these structures does not meet the requirements of SaNPiN 2.1.4.1175-02 and varies over time. The reasons for the change in the water quality in the manhole and the well and the ways to solve the problem are listed. The factors affecting the water quality in the manhole and the well are indicated – the characteristic of the water of the aquifer and the arrangement of the structures. The conclusion was made that it is impossible to make the optimal choice between a manhole or a well for the environmentally acceptable water supply of a country house for the quality of water in each of the water intakes. A comparative assessment of the manhole and the well is given for a number of indicators in order to optimize the choice between them.

The quality assessment of watercourse, located in a highly urbanized area was the goal of research. The SłuŻewiecki Stream, which flows in the southern part of the capital city of Warsaw is the subject of study. The aim of the research was to determine the tendency of the water quality changes in the SłuŻewiecki Stream, flowing in the highly urbanized area and being a sink of the non-point and industry sources of pollutions as well as the surface runoffs which comes from its catchment. The field research was conducted along the entire length of the stream in 2015 and 2016. The water samples were collected monthly from a depth to 20 cm. Water quality tests were carried out in accordance with the valid analytical methods. The obtained results point to poor water quality. Therefore it can be conducted that the development and use of the direct catchment is the one of main factors affecting the water quality in SłuŻewiecki Stream. The tributaries, often not inventoried, from built-up, populated areas, are the most polluted. Tributaries contain large amount of organic compounds and nutrients.

Water is a basic need that is very important for humans and other living creatures. Drinking water is water whose quality meets health requirements and can drink, it was clean water is water used for daily necessities whose quality meets the requirements of health and can be taken if it has been cooked. The quality of products is one of the most important factors affecting the company's progress, as well as for the water company. In this regard discuss about water quality control if it meets quality standards or not. Quality Control of water in accordance with the standardization and quality standards are allowed very closely related to the level of customer satisfaction. Control of the quality of a product can be done by measuring the different variables that influence it. One way to measure and determine the quality of a product is by using the Taguchi method is done with the design parameters is one of the design phase of a product or process. So hopefully by doing this study water quality PDAM Tirta Meulaboh can be controlled and can be controlled which can certainly improve water services to the people of Aceh Barat.Kata Kunci : Water, Quality Control, Customer Satisfaction, Taguchi.
