Conducted researches concerning cost of water treatment allow to formulate a hypothesis that "saving of water by household consumers leads to higher costs of production and distribution of water and in consequence tariffs of water. It leads again to the drop of water consumption, causing increase of average cost of water in the situation of not full use of the waterwork production capacity. Presented in the work method of construction of model equations requires that applied relations were the same in the long period. Possible to receive data was only from few years and not allow to say if it will be so in the long period. We assume the stability of existing relations and say that process of increase of water costs and tariffs is a concurrent process. It means that possibility of decrease of water use in households will be finished. People need some minimal quantity of water. Metering is thought by many people to be fairer than charging pro rata to property value, and it can certainly penalise waste and extravagant use. From the other side, change from flat - size charges to metering would cause high income occupants of large houses to pay less than low income householders in small houses. Above this limited use of water may result in unhygienic conditions and diseases. Meters also cost money to buy, to install, to maintain and to read, partially defeating their own purpose. They require extra pumping pressure and their first cost is appreciable. There is no indisputable proof that metering permanently reduces average in house consumption. People appear to reduce their consumption when first metered, but later revert to their previous consumption. Consuments must be aware of the fact that improvements of water supply and quality must be associated with higher charges for water consumption. Some parts of existing systems (e.g. pipelines) require extensive renovation, modernisation and automatization - all undertakings are very expensive.
