Abstract Fast-growing water demand, population growth, global climate change, and water quality deterioration all drive scientists to apply novel approaches to water resource management. Nanotechnology is one of the state-of-the-art tools in scientists’ hands which they can use to meet human water needs via reuse of water and utilizing unconventional water resources. Additionally, monitoring water supply systems using new nanomaterials provides more efficient water distribution networks. In this chapter, we consider the generic concepts of nanotechnology and its effects on water resources management strategies. A wide range of nanomaterials and nanotechnologies, including nano-adsorbents, nano-photocatalysts, and nano-membranes, are introduced to explain the role of nanotechnology in providing new water resources to meet growing demand. Also, nanomaterial application as a water alternative in industry, reducing water demand in the industrial sector, is presented. Another revolution made by nanomaterials, also discussed in this chapter, is their use in water supply systems for monitoring probable leakage and leakage reduction. Finally, we present case studies that clarify the influence of nanotechnology on water resources and their management strategies. These case studies prove the importance and inevitable application of nanotechnology to satisfy the rising water demand in the modern world, and show the necessity of nanotechnology awareness for today's water experts.

This paper analyzes residential water demand in Poland and the determinants thereof, including both water tariffs and income levels. Information on the price and income elasticities of residential water demand is crucial for effective management of water demand. We carried out this empirical analysis using several panel-data models. The analysis is based on data provided by the urban municipalities, in which the number of the end-users connected to water supply networks exceeded 50,000. We focused on the larger cities to obtain sample homogeneity in terms of the access to water supply and sewage collection systems, as well as the income structure. We found that the indicators of price elasticity of residential water demand in Poland are similar to those being known from the relevant surveys conducted in Western Europe. However, the income elasticity is smaller in absolute terms when compared to that in countries with more developed economies. Based on the results obtained, our prediction is that the decreasing trend of individual water consumption in Poland will slow down in the next few years. Our study is one of the first to investigate the price and income elasticities of water demand in Poland, and also one of the first such ones carried out for economies in transition.

Abstract The building water supply system is a fundamental unit in water supply systems as it is directly associated with end users. However, the studies available on its efficient design are limited. Water demand estimation continues to be an important issue in water supply systems' design because of its multifaceted nature. Hunter's curve, or Fixture Unit method, is widely used for estimating the load on plumbing. Regardless of its popularity, it has a few drawbacks and is arbitrarily modified in some plumbing codes. Fixture-use probability, a basic entity in the Fixture Unit and some other methods, is a difficult parameter to estimate. Commonly, high-resolution field data is used for stochastic modelling of residential water demand which may not be always available. The paper reviews important residential water demand models in view of their applicability in building water supply system design. The irregular nature of water demand in buildings is due to uncertainty in water-use behaviour of users at fixture level. Use of soft-computing techniques can provide an advantage over the other methods in modelling such behaviour. The paper also discusses reliability of building water supply systems and applicability of some common indices for estimating reliability of building water supply systems.

In order to meet the projected water needs of Shandong Province in the future, the system dynamics model of water cycle system is designed. The system dynamics model of water cycle system consists of three sub-models: population growth model, water demand model and water supply model. We use the logistic growth model to forecast the population in population growth model, use the water price elasticity of water demand to show how water usage responds to price change, and analyze the desalinization rate and the purification rate of water to meet water supply. In addition, by using System Dynamics modeling software, various types of models for water cycle analysis can be simulated. The model output shows this effect clearly..
