Subject: Water level in a concrete tank

I want to make more use of my tank water. My big concrete tank ie no tapping, is about twice head height so a ladder job and lifting a heavy inspection port to look inside which I am not about to do.

So suggestions requested for ways to check water levels without using ladders.

Tie a string to something that floats, throw the thing up into the tank’s opening, feed the string til you no longer feel the weight of the thing. Measuring the amount of string, do the appropriate maths.

That’s a good one. The inspection port is usually closed and the hole where the water goes in is pipe sized and has a pipe over it, just a small gap so not a throw in job but something could be rigged.

transparent pipe’s alright, need only be plumbed in at bottom

or float with something poking out the top indicating water height. Float with a bit of string over top with couple little pulleys, then hang it down, mark level on outside of tank’d do it, though be marked backwards, still probably easiest

and there are various electronic options I suppose.

It is possible to rig a pulley onto the float and have a rope attached that has a permanently attached weight on the outside of the tank. The lower the weight outside, the fuller the tank.

The suggestion of a sight glass is not silly, although glass is. Mount a clear tube (eg pvc hose) inboard of the outlet tap that goes to the top of the tank. A coloured float on the top of the water can give a clear indication of height.

I have one that looks like this. Not sure if it’s the same brand. Costs $18.90.

https://www.bunnings.com.au/rain-harvesting-water-tank-level-indicator_p4760065

Consists basically of a dial gauge, a float, and a string connecting the two.

this. It is what we use. thick fishing line or similar. large diameter pulley, mines homemade. sinker on the outside, float on the inside. reverse reading.

if you want to tell the amount of water in it from a distance, a broomstick with a weight on 1 end, a foam bouy float about 1 foot along it so it floats standing vertically and a fluoro/high vis flag on the top, can see it from a good distance and know the water volume from the height of the flag above the tank.

sight glasses/pipes are great, but anything clear always ends up full of algae

The float is the best idea. Cracks will also tell you. Salt encrusting may also help.

The hole in the top is only a poofteenth larger than the pipe that goes into it. I guess it was done that way deliberately to keep things out.

Where the water leaves the tank at the bottom. Fit a T section and a tap onto it, to which you can attach a piece of garden hose, To test open the gate value to the hose, then lift the hose until the water stops coming out, which will be the tank water level. Turn off tap and repeat when necessary.

From my perspective that is not so easy. Getting a bit of clear pipe that will remain straight over its entire length, putting it over the hole whilst allowing the pipe in and securing it so it remains upright against winds. We had a damaging storm cell here just the other day. V replacing one small elbow bend with a t bend and dropping into it a length of dowl with a float which I can see from the ground. So far that one works best for me.

It wouldn’t be much more than the light getting in now and less than the meshed plastic tank allows so should be ok. It is also cold water.

Well you could always hold the end of the pipe at the top of the tank, then slowly lower it until water comes out, which will indicate the tank’s water level.

That has advantages as well, no need to muck around on top of the tank to set it up and I only need periodic chicks no need to monitor constantly which the dowl method would allow.

Has this tank been cleaned in the time you have been there? We haven’t done it for a couple of years, but there is a bloke around this district that cleans them with something rather like a pool vacuum. The sludge goes onto the grass for us, good nutrients. And the cleaner can tell you where you are at.

I can tell where I am at but it is a ladder job and a pain, it would be full now, recent rain has it overflowing. I want to use sprinklers this year so more important to keep a handle on what the water is doing. This tank has only been used for house stuff and is usually overflows with any decent rain so the level never drops much. That is what I meant by saying I wanted to use more of the water this year.

Has this tank been cleaned in the time you have been there? We haven’t done it for a couple of years, but there is a bloke around this district that cleans them with something rather like a pool vacuum. The sludge goes onto the grass for us, good nutrients. And the cleaner can tell you where you are at.

I can tell where I am at but it is a ladder job and a pain, it would be full now, recent rain has it overflowing. I want to use sprinklers this year so more important to keep a handle on what the water is doing. This tank has only been used for house stuff and is usually overflows with any decent rain so the level never drops much. That is what I meant by saying I wanted to use more of the water this year.

What are the dimensions of this tank?

Probably 11 or so feet high and about the same across the middle.

So that’d be about 30 000 L, gee.

I want to make more use of my tank water. My big concrete tank ie no tapping, is about twice head height so a ladder job and lifting a heavy inspection port to look inside which I am not about to do.

So suggestions requested for ways to check water levels without using ladders.


I have a slightly more complex system on my 4000 l head tank.
Glass flagon in the tank acting as a float, heavy fishing line attached to float & exiting the tank. Attached line to weight approx equal to weight of flagon via a pulley. Second line attached to weight & over pulley. This line goes to the other side of the tank goes over a smooth bolt & on to an old CD.
The CD then shows the real water height not the inverse.

I have had a look at the tank and a bit of a think and decided that the hose method will be the best. I have to get a plumber in to relocate the pump and some pipes and put in a tap so I can use the domestic water supply to also run sprinklers and will get him then to replace an existing tap with a threaded tap so I can put on a hose fitting.

Cheers all.

fit a plastic tube along the side of the tank so you can see the water level.

allowing too much light on the tube means algae will grow and you’ll not see the water level
