    A Standardized Approach for Water Reduction Measures in Industrial Companies: Organizational Constraints and Effects on Economy and Environment2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The access of water globally is becoming more strained, why the focus on industrial water use is increasing. The present study examined how industries should approach water efficiency projects, what organizational constraints that should be addressed, and what effects water saving measures have on economic costs, environmental impact and influence from water related risks.

    The study has been conducted at Saab Group. Primary data for water supply amount and cost has been obtained from twelve sites for the year of 2018. Data from these sites has been used to estimate the water use for the other 43 sites included in this study. Interviews with employees across Saab´s organization and with external stakeholders have functioned as important sources of information, combined with investigations of internal company documents.

    To facilitate for companies to structurally address water efficiency projects, the concept of the Deming Cycle is developed in this study. The steps included are necessary to address major identified organizational constraints which are lack of communication, lack of incentives for employees, and lack of economic incentives. Furthermore, with water often having energy embedded into it, a new Water Management Hierarchy is developed to include the interrelated aspects of energy supply and energy recovery. The potential for pipe leakages and the challenge to detect these are also identified. If the time from leak occurrence to repair in 2018 was eliminated, the total water supply in Arboga could have been reduced with 10100 m3 which corresponds to 35% of total supply to the site, respectively 35900 m3 and 42% in Björkborn.

    In Tannefors, water saving measures are identified for a surface treatment process, a facility with testing equipment, and by utilization of groundwater. Not all water saving measures result in reduced annual operating costs, due to an increased energy demand. Furthermore, if neglecting the possibility of energy recovery when aiming for water use reduction, the results show that replacing a once-through cooling system using potable municipal water as a medium with a dry-cooling unit, can increase greenhouse gas emissions. In 2018, the simultaneously implementable water saving measures in Tannefors would have reduced the water supply with 40600 m3, which corresponds to 22% of the total supply to the site. The greenhouse gas emissions would simultaneously have been reduced with 0.4 tonnes CO2eq. If also addressing energy supply reduction and energy recovery, some measures achieves a reduction of over 35 tonnes CO2eq, which results in enhanced economic viability from reduced operating costs.

    This study suggest that organizational constraints have to be addressed to successfully implement identified water saving measures. To allow economic motivation for all water saving measures in Tannefors, a payback period of over 7 years has to be applied, which can be lowered if the measure also reduces energy demand or increases energy recovery. In order to avoid sub-optimization of water saving measures, the current Water Management Hierarchy has to include the aspects of energy supply and energy recovery. If the aim is to reduce a corporation’s water use, the largest sites with heavy industrial processes should be addressed first. However, the potential impact from water related risks at smaller sites should not be neglected, in order to ensure safe operations and avoid increased costs in the company´s supply chain.
