Hi guys,
Our well cost Eur5K, this included the drilling, the lining and the submersible pump. We also had to get a water-purification system which cost Eur2.1K.
As for "sewage system" we used the Bord na Mona Puraflo, this cost Eur5K and, as per usual, Bord na Mona just delivered the thing, had to hire a digger man to install it, (digger-men charge extortionate rates where I live!), and create the percolation area.
ALERT.
