I was interested in your reply.
Here in the Cook Islands we are going through the problems of supposedly nitrates etc leeching through to our lagoons.
The main problem we have is outdated standards and lack of of enforcement.
I have seached around a bit on the net on the septic subject but have not come up anywhere with let us say the “latest” standard.
Eg single, double, 3 chamber are the recommended standards. Standard to have effluent filters on the outlet.
Sizing and plans?
The “powers to be” say let’s put in three chambers tanks.
But they take a 1000 gallon tank and split it into 3!
I would be intersted in comments as well as sites showing plans and standards for sizing according to loadings.
Look forward to replies
