Trenching next to a weeping willow

[Canal Navvy]

I was trying to think of one that was compliant for direct discharge to a water course that didn't need a power supply

As I understand it you are contracting to someone who is having to update their system due to it discharging to a watercourse and have an easement over their neighbours land. In my experience domestic sewage treatment plants need a power supply to operate the aeration system. Selecting a system with a pumped discharge would make it easy to install the pipe run without undue disturbance and without any joints or risk of future blockage. 

 

 

 

I'm not contracting, I'm the head gardener of a property of which the large property next-door (non residential) has been discharging into a very old soakaway under my clients garden, this has become blocked, after a lot of meetings with various people the only really viable option is to take the discharge into a nearby watercourse. Its just getting past the willows that was my concern.

Gotcha 🙂

 

If you and your client are happy with the willows as they are then there is absolutely no reason to cause them any harm. 

 

A few years ago I installed a Tricel treatment plant that serves four holiday apartments that has a pumped outlet through a 63mm MDPE pipe. It would not be that challenging to mole under the trees and cause so little disturbance that by the end of summer they'd be no sign of any works. In your position I'd be resisting trenching as a non damaging alternative is reasonably practible.

 

Hope it all goes well 🙂

Few and far between, in fact, I service very few that are gravity discharge.
