The water issue
The importance of water is often undervalued.
We must all reconsider our current relationship with this limited resource.
Companies are realising water related risks could limit future growth.

• Competition over abstraction• Climate threats• Irregular quality• Accidental contaminations
Why a sustainable approach?
Production needs
Water Scarcity and Safety Compliance
Costs
Image
• Increase of production• Continuous and safe water supply• Avoid production shutdown
• Environmental guidelines• Shareholders expectations• Public opinion and corporate image• Sustainable development
• Water abstraction limits• Discharge limits• No discharge possible
• Water consumption costs• Discharge fees• Need for large volumes

Opportunity to treat and reuse water
Step 1 – cost reduction opportunities
Alternative natural water sources• Well• River• Sea• Borehole• Rainwater harvesting
• Effluent minimisation
• Demand management
• Bund water management
Step 2 - reuse applications
Result – a sustainable industry
Reduce Operating Costs

Savings that can be made
Case study 1 - distillery
Client needs:
• Create a flagship manufacturing site that demonstrates their ambition for a sustainable business using renewable energy.
The solution:
• Commissioning of a new bio energy facility.
• VWT contracted to design & build the dewatering & aqueous treatment plant. • Plant generates renewal energy from spent wash & liquors.
• Spent grain is separated & used to provide fuel for the biomass boiler.

Case study 1 - distillery
The results:
• Annual CO2 emissions reduced by 95% (56,000 tonnes)
• 80% of distillery energy requirements from biogas & biomass.
• 98% of thermal steam recovery.
• Over 60% of water recovery.
Case study 2 - dairy
• Operator supplying around 30% of milk consumed within the UK.
• 1.3 litres of water required for every litre of milk processed.
• Clear effluent produced from the onsite DAF and MBR waste water system that offered the opportunity for reuse.
• Saving on discharge costs.
The solution:
• Trials confirmed effluent from the MRB could be fed directly to an Reverse Osmosis system.
• Reverse Osmosis system to recover 200,000 litres a day.
Case study 2 - dairy
The results:• Reduction of mains and waste water charges by recovering
200,000 litres per day from steam raising and clean in place systems.
• Return of investment achieved in 2.5 years
• Environmental benefits

What’s next...focus on water!
Focus on Water
Three key steps for the beverage industry to consider:
• Work together to overcome misconceptions through clear, consistent and continuous communications about water reuse in the industry.
• Emphasize the value of recycled water as a sustainable resource that will help meet future demands in the industry.
• Take a more integrated approach to water management.
