Saving Water in Industry

Many industries have made substantial efficiency gains in recent years to reduce overall water usage. The next stage in this trend is to reduce drinking water usage by better utilising local alternative water sources.

There are common features of industrial precincts that are suitable for alternative water supply initiatives. In addition to the use of drinking water for non-drinking purposes, many industrial precincts have large roof and paved areas which provide a local source of roofwater and stormwater that can be captured and treated for use onsite.

While many industrial companies knowingly consume large volumes of drinking water in non-drinking purposes, it can be difficult to trigger a new approach to water supply without the in-house engineering expertise necessary to identify viable alternative water supply arrangements. The planning, design and installation process needed to implement these systems may also be perceived as onerous and a constraint for some companies.

Industry Water is specifically focussed on helping industry identify and implement cost effective ways to save drinking water. We aim to tailor our approach to each site by undertaking an initial appraisal of cost and savings potential and recommending a process to suit. The factors we typically consider to assess viability include:
 
Savings: Location and scale of avoidable drinking water usage;

Sources: Availability of a suitable alternative water source;

Practicality: Ease with which the water source can be harvested and the level of treatment required to supply the end use;

Process: Optimisation achievable through planning and design;

Drivers: Direct and indirect financial benefits (eg. marketability or sustainability gains); and

Financials: Funding sources and required payback period.
 
Most industrial facilities are suitable for alternative water supply systems. Typical alternative water sources and uses in high water using industries are described below.
