Information for plumbers and builders

The information on this page is for plumbers, kitchen fitters, builders, groundworkers, drainage contractors, house builders, and those working in the construction industry.  The construction industry has a really important role in preventing, identifying and addressing the polluting impacts from misconnections and other drainage.  Research has found plumbers cause up to 80% of above ground misconnections.  Kitchen and bathroom re-fits and other house alterations are also causes of misconnections. Some properties have even been misconnected when built.

Customers and property owners are becoming more aware and concerned about the environmental impact of their properties.  Our aim is to help professionals get the information they need to stop pollution, advise their customers and protect their reputation and business.  Please contact us via the enquiry form  if you have information to share.

It is an active, enjoyable and effective way of raising awareness of waste and water pollution, and helping make local environments cleaner and healthier places. It involves volunteers stenciling a Yellow Fish symbol beside drains as a reminder that any liquid waste entering these drains may go directly to the nearest stream or river, possibly causing pollution and killing wildlife. Read the yellow fish manual.
