Abstract Water is one of the cornerstones in human survival and a necessity for socio-economic development. Due to that, effective management of water demand especially in the rural area becomes vital. The objective of this study is to conduct a water demand study at Kenyir Lake, Terengganu using Micro-Component Analysis (MCA). Water demand is also being assessed using National Water Services Commissions (SPAN) Guidelines, parallel to water guidelines applied for Malaysia’s building and comparison purposes. MCA considers detailed parameters of water use activities of the respective study area, whereas SPAN Guidelines use the fixed values of average daily water demand according to the type of building. The available dataset was interpreted using MCA and SPAN Guidelines, resulting in total daily water demand at Kenyir Lake of 1249.8 m3 and 1254.1 m3 respectively. Estimated water demand using SPAN Guidelines is found to be higher than MCA. The value differences occur due to the average water demand value in the guideline that is limited to a specific type of premises and does not comply with premises there. The estimated water demand can be adopted as a baseline for water companies and the government to improve the demand and supply of water.

Abstract Integrated water resources management (IWRM) is being implemented all over the world, considering its wide area of applications and flexible spatial scale. Scientists have found IWRM useful in an Indian context also where a coordinated development of water and land resources is sought as part of complete economic, social and environmental welfare. The paper presents the concepts of ‘Local IWRM’ planning applied to water conservation and management in a case study of Ur river watershed in Tikamgarh district of Madhya Pradesh (India). The Plan considers effective utilization of land, water and other available natural resources, linked to the vulnerabilities and livelihood opportunities in the geographical area. The IWRM Plan, designed in three sections – (1) water management, (2) land management, and (3) livelihood management – provides specific suggestions on the activities under these three themes as useful inputs to the District Irrigation Plan (DIP) of the Government. The proposed IWRM Plan intends to promote the component of water demand management in district level planning and is envisioned to be an ‘implementable’ planning document for district level government. Acceptability of the IWRM plan is potentially enhanced as the plan was developed through a participatory process, wherein all relevant stakeholders were consulted at different stages of development.

Residential Water

A residential water demand equation is estimated using a panel data sample of five Portuguese local communities and 72 months, corresponding to a total number of 360 observations. Because of the presence of multi-part tariffs, we use the two common price-related variables: marginal price and difference as explanatory variables. To prevent the simultaneity bias from using observed quantities to determine the values of marginal price and difference directly from the rate schedule, we use an instrumental variable approach to create a constant marginal price and difference parameters for each rate structure. The price elasticity values obtained fall within the range of those found in other case studies. Thus, although presenting weak elasticity, price seems to play a role in water demand management. However, we do not confirm the expected influence of difference on residential water demand. This can be a consequence of the complexity of the Portuguese water tariffs and the confusing signs that come from the simultaneous use of fixed quotas and increasing block tariffs. So, it is imperative to clarify water tariffs objectives by reviewing the Portuguese water tariffs design processes.

Abstract In this paper, a new approach for supplying water to shrimp production ponds in Purworejo, Indonesia, is proposed. The paper covers the design of a solar-powered DC water pump system (SWPS), system performance analysis, and economic analysis by comparing it with the existing fossil-fuel-powered pumps. The mathematical approach for the designing process is shown and Lorents Compass alternative tool is introduced. By taking into consideration the daily water demand of 50 m3/day, the annual-averaged local solar irradiation of 4.7 kWh/m2 per day, and the available components in the market, an SWPS in Purworejo would comprise a 1200 Wp PV panel and a 600 W DC pump submerged in a borehole in the seashore. The SWPS would be able to meet the daily water demand with small seasonal variations. The financial analysis shows high feasibility to install SWPS in Purworejo with a 1,6 years simple payback period, which is very short. The SWPS would provide more than 20 years of free energy for the farmers to draw seawater to the pond each day when the sun shines. It can provide not only environmental and social benefits but also significant economic advantages, both at the farm and the national levels.

This research aims to study the management of water demand in different product markets in downstream lands of Yengejeh Dam in Neyshabur. This is an exploration research survey and library study conducted in 2015-2016. The required information to test the research hypotheses was gathered by questionnaire. The statistical population includes 150 wheat farmers randomly selected A scenario of increasing the elasticity of product demand in resource allocation in the competitive and monopolar water market was developed by assimilation algorithm in the studied region. According to the market situation of water in the region which is almost similar to monopoly water market, the results suggest that wheat farming can be superseded by farming some other trade and export-oriented crops. This brings about an increasing amount of product and yield per hectare of land with using less water supply and less area under cultivation.
