 Re: Not on mains drainage?
Ours is a poso negro which is about 16m deep and doesn't need emptying ... rock filters everything through ... ewwww ...
In your case, I can see why it could be the same. Any poso negro could drain through the barranco rock. But I've also heard of proper septic tanks which need emptying. Don't know how to find out which would be the case though. |
