Use of water for cleaning livestock housing and abattoirs - WU0136

Significant volumes of water are used to wash down livestock (particularly dairy and pig) units and abattoirs. This water is often collected as slurry, which has to be stored and spread at considerable costs to the farmer. In addition this poses a risk of diffuse pollution. Reductions in water usage will assist farmers and abattoirs to adapting to climate change as well as improve economic viability, contributing to overall sustainability.

However, evidence and best practice is fragmented and water consumption is not a priority for many operators. The main objective of this study is to produce an in-depth review of existing literature on water usage with a view to establishing benchmarks as well as identifying new and innovative technologies. Due to the low uptake of water saving measures in the industry, this will be supplemented by a consolidated dissemination effort.

The detailed research objectives are as follows:
1. Produce an in-depth review of the state of knowledge with respect to the use of water for cleaning livestock units and abattoirs, drawing on experience world-wide and in other sectors and industries.
2. Establish and disseminate best practice technologies.
3. Establish benchmarks for water use in livestock units and abattoirs taking into account best practice, economic and environmental impacts.
7. (b) Objectives

1. Assess available data (from literature review and primary research if required) on water use on livestock units and in abattoirs to establish benchmarks, taking account of best practice, and economic and environmental considerations.

2. Assess worldwide research and data on water use for cleaning livestock units and abattoirs, drawing on research conducted in other sectors and industries where appropriate, and identify actions taken and technologies used to improve water use efficiency and analyse the effectiveness of these.

3. Establish best practice technologies.

4. Disseminate information on best practice technologies (including case studies) and benchmarks for water use to the industry, policymakers and their advisors, and other relevant stakeholders.
