Pump for washing machine waste water (downhill from foul water)

[skhudy]

We have a house built on a slope where you go down to the garden with a downstairs utility room (washing machine / sink / dryer). There are no services or pipes etc in the garden, its all at the front of the house, there are no house to the rear its a railway line.

Redoing the neglected garden and find the waste water from this is dischanging into a 110m pipe which runs down the garden - believe to a gravel pit on the side of the garden which is always muddy.

Reading into this, the waste water is "grey" water and should not be running into the ground.

I was thinking a small underground polytank with a grey water pump to get this waste water up and out to the correct drainage which is 2.5m up and 10m away.

Any tips or ideal i need to be aware of?

Something simpler may well do the job, https://www.sfasaniflo.co.uk/en/products/sanispeed although there is limited retention should the unit fail mid cycle on the washing Machine.

Depends really what you want to spend, a Lifting Station will have greater capacity, so would at least allow the machine to complete a cycle without flooding the place, and could have a high level alarm fitted to warn of Pump failure before the washing machine was used again.

If your washer were installed on a table/countertop or similar not-on-the-floor situation, I dare say the pump in the washing machine itself will have enough oomph to lift the waste water to the level required. Is there something you can attach pipework to (eg a fence) to complete the run?
