On our families farm we pull water from lakes and creeks, use to be the main
supply but now only as a backup to a deep well.

We installed a 2hp volume pump (or maybe called low flow) at the source. 2
inch line for about 200 ft with about a 20 ft rize. Power was supplied from
a nearby barn with big enough underground wire to match the current draw for
240V to keep voltage drop minimal.

We also had a 1/12 pump same type at the end of the 200 ft run as a boost
pump at the edge of the gardens (about three acres), not a pressure type
pump.
We could run about six of the older brass rainbird sprinkers and get enough
coverage, about a 30 foot throw of water. If we turned on the second pump
pressure increased dramatically and could run 12 to 16 sprinklers easy.

We did not have any major filters, sprinkers used would just pass any debri
that was not caught by the screens, the foot valves had course screens but
we also added a finer screen mesh around the foot valves that could be
easily removed and cleaned when needed.
If using sprays or gear driven sprinkers, do like I had to and use a
swinning pool sand filter that can be back washed. The bigest problem with
any surface water source can be alge, can be a big pain clogging up filters
and some types are not good for plants. Make sure the water source is fairly
clean.

2 inch pipe was used for the long run for minimal friction and high flow at
low pressures. this setup works great for us. and the deep well also having
a 3hp pump and 2 inch line has the pressure we need without boost now (can
pump 75gal per minute and not go dry), was an old community water system
near us, now the county supplies water so we got the well to use.

We also had a thrird smaller pump on a nearby creek to pump addtional water
into the lake (small 2 acre pond) when we had to pump a lot out of the lake.
We dug into the edge of the creek, installed concrete 3 foot diameter sewers
down about 10 feet. with holes and screen to allow water in provided a
reservior to pump water out of easliy, had a 1 hp pump and a 1-1/2 inch line
up to the lake.

Maybe overkill for what you need but hope give you some ideas.

There is a lot of information on the internet on how to design irrigation
systems. several formulas on sizing pumps and pipe sizes for the amount of
flow, pressure and rize needed, etc.

Hi all,

Can anyone recommend what I need to do this?

The middle of the yard is about 150 feet from the creek with about a 15
foot rise. I want to run about 4 or 5 sprinklers at once. I would like
to run a hose from the creek to the pump (or does the pump have to be
near/in the creek?)

I'm sure I will need a filter for this as well, but I would like to
have a pump that would tolerate some amount of trash.

By the way, I do intend to check with the County before pulling water
from the creek for irrigation.

Thanks,
Budman
