First, contact your water wholesaler. They can advise you about known problems on the network, like burst pipes, leaks, or planned repairs, and how long it’s likely to take to sort them out. They may deliver extra water, especially for vulnerable sites like hospitals.
Wholesalers are responsible for ensuring clean water is supplied to your site and wastewater is taken away. They usually publish information about bursts, leaks, and repair work on their websites.
A burst pipe or leak could prevent water from reaching your taps. Some leaks are underground so may not be obvious. To check for leaks, follow this simple leak test.
If you think you have a leak and your wholesaler says there aren’t any water supply issues on their network, you’ll need to call a plumber to get it fixed as soon as possible. An approved list of plumbers in your area is here
It’s worth planning in advance, so you know where you could get an alternative supply of water for your business in an emergency.
If your wholesaler can’t deliver alternative water to your site and you need water to protect your business, contact Water Direct on 03453 451 725, an emergency water supplier. Please note that you’ll need to pay for their service.
Report any burst water mains or pipes and leaks as soon as possible to your water wholesaler. Many allow you to do this on their website, but emergencies should always be reported on their emergency phone line.
Wholesalers sometimes issue leakage allowances, and we can help with this. To claim, send the following information to email@example.com:
Who repaired the leak (e.g. plumber, yourself)
The date of the repair
A plumber’s report or invoice and any other evidence, such as photos
A meter reading taken directly after the repair
A meter reading taken at least 14 days later
If you’re unsure whether you can apply for a leakage allowance, call our friendly Customer Service team on 0330 6600 137 or email firstname.lastname@example.org – they’re happy to help!
If you’ve had a burst pipe on the private pipework supplying your site, we’ll consider making an allowance against your sewerage charges for the water lost. Please supply the same information as above to check whether you’re eligible.
Ask your wholesaler whether there are any bursts, leaks or repair work on their network that could be affecting your site (some publish this on their websites and social media channels). These are common causes of pressure changes.
Check for plumbing issues on your site, like a partially closed stop-tap burst pipe or leak. Some leaks are underground so may not be obvious. To check for leaks, follow this simple leak test.
If you think you have a leak and the wholesaler says there aren’t any water supply issues on their network, you’ll need to call a plumber to get it fixed as soon as possible. An approved list of plumbers in your area is here.
If you don’t discover any causes, report the low pressure to your wholesaler, who can then investigate.
If you are experiencing flooding from drains or sewers, contact your wholesaler right away on their emergency number.
Sewer flooding is the worst way that our customers can be failed by the water industry. One of the impacts of climate change that’s already happening in the UK is increasingly intense but sporadic periods of rain, leading to flooding from rivers and sewers.
Sewer flooding can also be caused by blockages in sewers, causing wastewater to flow out onto roads, into water courses/landscape or into buildings etc. Both cause disruption and often high clean-up costs, as well as negatively impacting the environment by, for example, damaging the biodiversity of streams.
If your business has been affected by sewer flooding, wholesalers have compensation schemes which you can apply for. It’s also important to check that your insurance covers such incidents. Such issues should not reoccur, but ask your wholesaler about any mitigation measures they can put in place or recommend to protect your business from any future sewer flooding.
Our customers’ actions – both at work and at home - influence how likely it is that their communities will experience flooding, and how severely they will be impacted. Actions which can have a negative impact include:
Incorrectly disposing of waste like oils and fats, chemicals and wipes into drains and sewers causes slow draining or blocked sewer pipes, which lead to bad smells and flooding.
Large changes in how much water people use (because this then becomes wastewater) can overwhelm sewers.
Poor maintenance of wastewater pipes can cause blockages or flooding.
Businesses can reduce the amount of rainwater entering sewers from outdoor surfaces on their sites like roofs and car parks by capturing their own rain or giving rainwater somewhere to go other than down the drain.
You can do this by installing water butts to collect rainwater for watering plants, landscaping in wild wetland areas or ponds, and breaking up tarmac and concrete areas with flower beds and tree pits. These sustainable drainage systems can divert or temporarily store rainwater to slow down its progress into sewers.
Installing rainwater harvesting and water recycling systems can divert rainwater or recycle used water for non-drinking uses like flushing toilets and washing clothes.
Drinking water in England and Wales is of a very high quality, but you may occasionally become aware of a different taste or smell. This could be due to:
the use of chlorine to maintain good hygiene in the pipe network
seasonal water quality effects creating a musty smell or earthy taste
a change in where your water comes from or how it is treated
your plumbing, which for various reasons can cause a range of tastes including metallic, salt, rubbery or earthy tastes.
If you experience this, check whether your neighbours are having similar problems. Also try to record when the problem started. For advice about taste and smell please see the leaflet on the Drinking Water Inspectorate (DWI) website here.
Only use cold water from the kitchen tap for drinking or cooking because other rooms are usually served from a storage tank in the roof and use other pipes, so are not as fresh or as safe as water directly from the mains.
If you suddenly notice a particularly bad or strong smell or taste, contact your water wholesaler immediately on their emergency number listed above.
Your water wholesaler can help you find out whether there’s anything wrong with your site’s plumbing. They can carry out an inspection and test samples of your water. You could also get advice from a qualified plumber.
If your drinking water comes from a tank, you will need to contact the water treatment company or management company which serves your site.
