Water supply

[pappuller]

We are aiming to upgrade our mains supply in the near future, currently have an old black 20mm supply coupled with a borehole which copes with demand at the moment.
We are on a shared supply with a neighbour on moderate usage(turkeys )
We are planning on putting in 2 32mm supplies as our main is only 75mm and our provider will not allow anything bigger.
My question is what are peoples thoughts on how much volume we will lose over the 250m from the main to the farm ?
We currently manage approx 12 l/m with our present main.

One helpful piece of information to know would be the pressure at the main. This will have quite an effect on the flow rate.

Get a pressure reading off your water supplier.
32mm will be a big difference compared to your old 20mm supply.

You are dairy can't you drill a borehole would possibly pay very quickly.

What’s stopping you getting the 32mm supply from main to meter from the supplier then running 40 or 50mm through your own land? A small section of 32 won’t create such a restriction as quarter of a kilometre

Borehole been in for 3 yrs but doesn't produce full requirement

Does that create more volume ?

The only information we have had is that we have 12 l/min at our meter

Pressure drop is easy to figure out. You just need the pipe size, and flow rate, pipe type helps keep it accurate, steel will be rougher than plastic. Determining the pressure at the main shouldn't be too difficult. If you can measure the pressure with no flow, then that's what you have to work with, the static head from the main being higher or lower will be the same with the new service. I'd guess turkeys go to sleep and there's not much flow at some point in the night when you could get an accurate no or low flow pressure reading.

What about a big tank filling from the borehole 24/7 Then use a pump set out of that to provide a pressurised supply round you pipes
Might be cheaper than 2 x 250m 32mm supplies with the resultant water bill

Get another one drilled pronto, we only use mains for houses and parlour circulation wash, no treatment mither that way.

Anywhere you can install a reservoir that fills in time of lower use such as at night?

In the situation you describe there would be hardly any loss through 32mm, especially as you only have 12 l/min to start with.

We have this already but we physically need more water as the business is expanding and the borehole is at capacity

We have a very flat usage curve, dairy cows milked by robots

Thank you, United utilities are either unable or unwilling to give us an estimate of how much water we can expect at the meter point

Have had a borehole for 3 yrs

 

[Kevtherev]

Any natural springs on farm?

Several farms around here are running two or three and different heights, all pumped to the same header tank and using the same filtration system. Looking at £3-4k to drill

Tbf its something we looked at but we are on sand and its very hit and miss
