Let's Stop The Block - At Work

If you run a business there are many simple steps that you can take to help reduce the cost and mess of blocked drains. It is important that you encourage staff and customers to play their part too:

In your toilets:


Display our posters and leaflets:
You can download our Stop The Block posters using the links below, or email letsstoptheblock@dwrcymru.com now for your free poster kit.

  • Provide small bags and a clean, convenient bin in your toilet together with nappy disposal facilities to make it easier for your customers to dispose of sanitary products and wipes, which should not be flushed.

In your kitchen:


Don’t pour cooking oil, fat or food waste down the sink:
You should only pour away water from washing cooking utensils and cleaning.

  • Train your staff:
    It is important that your staff understand why it is important not to let food waste, fat, oil and grease go down the kitchen sink. Ensure they have read our leaflets – download using the links below or email letsstoptheblock@dwrcymru.com now for your free poster kit.
  • Display our posters and stickers:
    Position posters in key locations around kitchen areas as a reminder to staff.
  • Prepare items before washing them:
    Scrape off all food residues and wipe pans and plates with paper towel before washing them.
  • Use strainers in your sinks:
    Strainers will prevent food waste from going down the drain.
  • Do not use food waste macerators:
    Macerated food waste and the fats contained in it can lead to the formation of blockages.
  • Store waste oil:
    Collect used cooking oil in air-tight containers in a secure area. The waste oil will need to be collected and removed by a licensed waste carrier.
  • Consider the installation of a grease interceptor or enzyme dosing system:
    It is important that your business is doing everything to control discharges of fats, oils and grease to the sewer network. In most cases catering establishments will need to install a grease interceptor or dosing system to achieve this. Read our leaflets for further advice.

Thank you for your support.
