Damp cellar

[DonkeyApple]

Our cellar is an old coal bunker that as the property was extended was converted into a modest cellar near the centre of the house. It has a porcelain floor and limestone walls. It doesn’t flood but is too damp due to groundwater naturally seeping through the walls. It’s enough moisture to ensure wood goes mouldy.

A good sized dehumidifier keeps it under control but extracts 7 litres of water a day which is a pain to empty. As the cellar is ‘landlocked’ I’ve not thought of a suitable means to automatically drain the dehumidifier tank as running a pipe seems the only logical conclusion.

When people run sump pumps in wet cellars is the default solution to tap into the soil pipe to dispose of the water?

The dehumidifier needs a constant fall for the drain off and what I was going to do was run the drain into a boiler condensate pump which can then pump the water upwards and out to where ever I needed. Something like this below

Yup, a pump system will be needed, I was more wondering where the water is usually disposed of, whether I to a soil pipe or general drainage etc. With the cellar being somewhat landlocked it’s going to be quite difficult to route piping to any domestic drains.

It's plain clean water so you can run it to any drainage you like, or even collect it like you would rainwater.

If you're removing seven litres of water a day, you'll be using a fair amount of electricity to do it. Have you thought about getting it fibreglass lined (or similar)?

I did consider tanking it but it’s not a huge space and tanking would remove a noticeable % of area. It’s also lovely Cotswold stone and tanking would be a last resort.

I have pondered painting it with that special tanking paint as there isn’t an issue of standing water just damp so that may work.
