Yes, we offer a lifetime of care and service for your equipment after the initial design and installation. Please see our service packages or speak to a member of our team to find the right care package for your system and requirements.

I missed my service. What do I do?

Give us a call on 01706 813733, and we’ll get your service booked in as soon as possible.

Do I need planning permission for a septic tank or sewage treatment plant?

Yes, you need to secure planning permission and building regulations approval for all septic tank and sewage treatment plant installations. For more information, please contact your local council.

Do I need to be in when you come to install or service my sewage treatment solution?

No, as long as we can access the equipment, you don’t need to be there when we attend site. However, if you have any questions about your sewage system, it’s always best to be on-site to speak to our experienced engineers.

Does my septic tank or sewage treatment plant need to be emptied?

When we come to service your equipment, we’ll advise whether it needs emptying or arrange to drain it when we attend site. Most modern small domestic systems only need to be emptied once a year. Large domestic and commercial systems usually require more frequent emptying. Please call us if unsure.

Are sewage treatment plants noisy?

No. As long as your sewage treatment plant is installed correctly, it should operate virtually silently.

Do sewage treatment plants and septic tanks smell bad?

No. Providing it’s been installed correctly, in line with Environment Agency standards, your sewage treatment plant will be odour-free. If you detect an odour, your system probably needs maintenance or repair work. If this occurs, please contact us to arrange a site visit so we can resolve the issue.

Can I build a deck over my treatment tank?

Yes, as long as it’s small and light enough for the engineer to remove it for a service, or for you to remove it before we attend site for a service.

Can rainwater enter my treatment plant?

No, sewage systems and septic tanks must not accept any rainwater, as this would increase the flow rate and affect performance.

Is my septic tank/sewage treatment plant full?

We will advise on our service report if the tank is full. If it is, we can arrange to have it emptied, or you can arrange this yourself.

What happens when my pump is out of warranty?

Our engineers carry a full range of pumps and can usually replace these at the service visit. If the part required is out of warranty, we will ask first before replacing any parts.

Do sewage treatment plants and septic tanks use chemicals?

No, all filtration is natural and chemical-free, making them environmentally friendly and kinder to wildlife and plants.

I have roots growing, can they be removed?

Yes, the service engineer can usually remove roots during a site visit.
