I still cant see the need for wet pipes, going to ground level, then across and back up.
Even if the tank is 50 metres from house, IF needed, pipe can stay at 2 metres or whatever above ground.
If some one needed to 'disguise' the plumbing, grow some passion fruit on 6 " dog wire,
raspberries, peas, beans, grapes or even climbing roses. No end to what can be grown.
Back to growing up, unlike now where every opening has stainless steel mozzie proof wire,
no one had anything, the water was drinkable, and nobody got sick.
Never had a "wet area' on my tank. Never heard of one 'till here. The thought of what is festering
in those 'wet areas' is scary.Used a grey water diverter, open 'all the time' on my tank,
so all dirt and leaves dumped into a pipe and on the ground. After seeing a good flow,
go out in the rain and close it, so that water from 3 down pipes, flowed into tank.
Never heard of a wet area, fast flowing water will NOT deposit sediment, and it sounds
like everyone is over complicating catching a bit of rain water.
The diverter when open runs water in from the R.H.S. (or left) and dumps out the bottom.
Twist the centre piece 90 degrees, and water flows from left to right, through some more pipe,
then a 90 degree, (or whatever), elbow, depending on the tank, and into the tank.
Simplest way on earth to dump "sedimented or leafed up water" water.
Hardest part, you will get wet, for as long as it takes to get to your diverter.
It can be near the house, and tank could be 100 metres away,
so takes about 3 seconds to get to it, close it once only.
When it stops raining, open until the next rain. Cost, $30, and you can't forget to flush
you dirty, contaminated stagnant wet area. If not at home when rain starts,
may miss out on catching a little bit of water, but much better than risking "dirty"
water being caught.
