Water efficiency and effluent audits help to identify areas of improvement to reduce your water and effluent charges as well as supporting your corporate social responsibility (CSR) targets.
We can provide a personalised view of how your business could save money, improve water efficiency and reduce effluent charges, without the need for a site visit through our informative desktop audits.
Using data specific to your business, our remote water and effluent audits provide an initial idea of how and where your business could save, which can be used to demonstrate the value of future investment in streamlining your business’ water infrastructure.
Our team will combine the information you provide with years of experience, practical knowledge and benchmark data from similar businesses in your industry to provide a personalised set of recommendations for improving your water management.
By analysing data such as your water and effluent costs over the past few years, the size and location of your site, how your business uses water in its day-to-day operations, and an estimate of how many people use the site in a typical day, our experts will provide an efficiency audit report that is as accurate as it can possibly be without an in-person site visit and inspection.
Desktop audit are a great first step on your journey to save money and be that little bit kinder to the environment. With our Onsite audits you will get all the above but also the added value of an auditor on site, which will allow us to notice any behaviours or equipment which may be contributing to wasted water or increased effluent going down the drain.
Both our Desktop and Onsite audits can also incorporate Grey Water Recycling (BS EN 16941-2:2021) and Rainwater Harvesting (BS EN 16941-1:2018) feasibility.
A water and effluent audit looks for opportunities to reduce water consumption, unnecessary wastewater, effluent charges and associated costs. This can include analysing bills and consumption data, comparing performance against similar businesses, identifying potential leaks or inefficient processes and assessing opportunities for measures such as smart metering, grey water recycling and rainwater harvesting.
Yes. A desktop water and effluent audit can use information such as historical water and effluent costs, site size and location, water-use activities and the number of people using the site to identify potential savings. An on-site audit can then provide a more detailed assessment by identifying equipment, behaviours or processes that may be contributing to unnecessary water use or effluent discharge.
Businesses may be able to reduce trade effluent charges by lowering the amount of wastewater they discharge, reducing the strength of the effluent or improving processes so less contamination enters the wastewater stream. Water reuse, recycling and better process control can also help. An effluent review can identify where changes are likely to produce meaningful savings.
Effluent charges cover the cost of collecting, treating and disposing of wastewater produced by a business. For trade effluent, charges can vary according to the volume and strength of the wastewater being discharged. Reviewing how much effluent a site produces and what it contains can identify opportunities to reduce these charges.
Trade effluent charges are generally based on both the volume of wastewater discharged and how difficult it is to treat. Factors such as chemical oxygen demand and suspended solids can influence the cost. Sewerage companies commonly use the Mogden formula to calculate charges, meaning that reducing the volume or strength of effluent can potentially reduce a business’s costs.
Trade effluent is wastewater produced as part of a business, manufacturing or industrial process that is discharged into the public sewer. It can contain substances such as chemicals, oils, fats, suspended solids or organic material and is treated differently from ordinary domestic sewage. Businesses that discharge trade effluent normally need consent from their sewerage provider.
Water efficiency can be assessed by comparing the amount of water consumed against an appropriate measure of business activity, such as employees, visitors, production output, floor area or operating hours. Historical consumption and benchmark data from similar businesses can also help identify unusually high usage and areas where improvements may be possible.
Improving water efficiency can reduce operating costs, lower wastewater and effluent charges and help businesses meet environmental and sustainability targets. It can also make sites more resilient to rising water costs and periods of water scarcity. Understanding where water is being used is an important first step in identifying opportunities to reduce unnecessary consumption.
Businesses can lower water costs by identifying leaks and unnecessary consumption, improving water efficiency, checking that charges accurately reflect site usage and reducing the volume of water discharged as wastewater. Opportunities may also include smart metering, process improvements, water recycling and rainwater harvesting. A water and effluent review can help identify which measures are likely to deliver the greatest savings for a particular site.
A water audit reviews how, where and how much water a business uses to identify opportunities to reduce consumption, waste and costs. It can involve analysing historical water and effluent bills, meter data, site information and operational water use. A desktop audit can provide an initial assessment using existing data, while an on-site audit allows equipment, processes and water-use behaviours to be investigated in more detail.
