Thanks Arimeh for your reply its awesome,

Could you do a little rinse and wring of the wee nappies then pop them into the pail to reduce the intensity of the amonia?

Dh and I have talked about installing another large tank to help feed the well but it will be a big and expensive job 5K-8K for the size tank we want then we'll need a plumber put gutters on the top shed and we'll have to dig quite a trench to run the water to where the well is. Am going to look into grants and rebates but its tough because we live on a farm so its a bit different then if I was in the city with town supplies.

It is something we need to do anyway as I never want to have to pump dam water into the house well like MIL did - it stinks.
