Abstract

Purpose

The purpose of this paper is to present a case study on how drinking water consumption could be potentially reduced by the introduction of dual water distribution networks. Since water of this quality is required only for drinking, cooking, bathing, and washing, delivering such water for uses that require non‐drinking water quality represents a tremendous waste of water and energy, and contributes to environmental pollution.

Design/methodology/approach

An overview of dual distribution networks in several countries is presented. Kuwait, in which 86 percent of the freshwater network has a parallel brackish water network, is the leader in this field, with brackish water used for a range of outdoor activities. The residential sector is the major consumer of freshwater in Kuwait and the control of demand in this sector will be a key factor in curbing the overall demand, which without any demand management measures is expected to quadruple by 2025. Computer modeling based on existing water use statistics and the proposed phasing‐in of a dual distribution network for indoor use in households has been undertaken to determine how the large quantities of reclaimed can be used to reduce drinking water consumption.

Findings

The paper presents a modeling exercise that demonstrates that by using reverse osmosis (RO) treated wastewater for toilet flushing and watering the gardens, water consumption demand can be stabilized at present levels over a 20‐year period.

Originality/value

The paper concludes that with foresight and long‐term planning it is feasible to implement a dual water supply network in a major city, on a scale which may lead to saving up to 25 percent of drinking quality water on top of other traditional water conservation measures.

Abstract

Purpose

The purpose of this study is to examine the role of attitude, religiosity, awareness and subjective norm toward trust which influences purchase intention regarding Islamic insurance in Indonesia.

Design/methodology/approach

This research uses quantitative methods. Online questionnaires are distributed and collected for people who already have an insurance policy, have the knowledge and are interested in buying Islamic insurance in Indonesia. A total of 322 valid responses were collected using non probability purposive sampling and snowball sampling method. To achieve the purpose of this study, an analysis using SEM or structural equation model for hypothesis testing was performed.

Findings

The results show that trust significantly affected purchase intention regarding Islamic insurance. Other than that, trust is significantly influenced by awareness, religiosity and subjective norm. Moreover, the attitude toward trust found that not significantly related.

Originality/value

The originality of this study is the first research integrating attitude, religiosity, awareness and subjective norm, mediating by trust toward a purchase intention of Islamic insurance in Indonesia.
