Trade effluent is wastewater that
businesses discharge to the public sewer.
It usually requires consent as
it can impact the environment, our sewage treatment processes and
can only be given by us for discharges in our region.
From 3 April 2017 traders will need to consult their water and sewerage
retailer to start this process as we will no longer provide services
to traders and other non-household customers under Open Water.
Trade effluent does not include
domestic discharges, such as toilet flushing or hand washing. It does include
wastewater from any trade activity such as commercial laundries, food
preparation, manufacturing, metal plating, etc.
Some businesses don't require trade effluent consent. These include:
To find out if your business needs one, contact your water and sewerage retailer.
All other trade effluent discharges require consent. It is illegal to discharge trade effluent to sewer without consent.
From 3 April 2017 you will need to consult your water and sewerage retailer to begin a consent application.
From 3 April 2017 you will need to speak to your water and sewerage retailer to start a consent application. You will need to complete form G/02 available from your retailer. Please note that your retailer may set an application fee.
We are required by law to determine the consent within two months. Sometimes it can take longer - especially if we need to build new infrastructure or treatment processes.
If you're thinking of a new or substantial change in the strength or volume of your discharge,
or your water and sewerage retailer as soon as possible.
Most water and sewerage retailers will apply a consent application charge. When your consent is issued, you'll need to pay treatment charges based on the volume and strength of your discharge. Find out more about our
Businesses that discharge sewage to the public sewer may need a trade effluent consent. This is because the discharge can impact the environment, our sewage treatment processes and infrastructure. The consent may include:
It will also specify the sampling point, discharge to sewer location and anything else that's relevant to the discharge. From 3 April 2017 you will need to consult your water and sewerage retailer to initiate a consent application using form G/02 available from the retailer's website.
Contact your water and sewerage retailer soon as possible if there's a significant change (e.g. more than 10%) in the strength, composition or volume of your discharge. A change could impact the environment, our sewage treatment process or infrastructure.
If this change is an emergency, call us immediately on 0345 600 4 600 (24 hours).
If you're building a factory please contact our
developer services team
for a new connection to the public sewer. You will also need to submit to your water and sewerage retailer a completed trade effluent application form G/02 available from the retailer's website.
It may take some time to check we have sufficient capacity so contact us as soon as possible. There is no charge for this consultation.
Regarding trade effluent consent for portable toilets:
If you run a mobile business that provides services including bin washing, vehicle valeting, central heating drainage, steam cleaning etc. then you need to apply for trade effluent consent. Wastewater should never be disposed to a highway drain or surface water gulley.
Any continuous operation will require trade effluent consent from your water and sewerage retailer and you should send them a completed G/02 form which they can provide you with.
Temporary or one-off discharges (less than six months) will require authorisation by us so you should complete the
application for a temporary discharge
on our website and submit it to us.
Water and sewerage retailers will be essential for all trade effluent customers from 1 April 2017. Wessex Water will charge retailers for trade effluent discharges to foul sewers then bills to traders will be compiled and sent by your retailer.
From 3 April 2017, consent applications (form G/02) and general enquiries (form G/01) must be submitted to Wessex Water via retailers.
Your water and sewerage retailer will deal with all enquiries relating to:
Contact us immediately on 0345 600 4 600 (24 hours) in the event of a chemical spill, treatment plant malfunction or other emergency (such as a fire) at your premises. This requirement is part of your trade effluent consent conditions. We will notify your water and sewerage retailer as soon as possible if you do contact us for this reason.
Any other query should be submitted to your retailer on form G/01 which will be available through the retailer.
