I am designing an irrigation system using etot and veg type.
I have subscribed to a weather providing service which supplies me with rain totals and the etotot for my location. I amusing to formula to calcualte how much water the grass needs
Etot X veg type(kc) = water needed in inches for the day
I have the value of .1521 for my etot for a given day
it is grass so the kc is .62
this should give me the value less other factors of the water needed in inches that day.
i get an answer of .9 based on what i know for this area i would need twice that. am i doing something wrong

Hello, I would like to ask about the hydraulices of closed irrigation canals and the possible cross sections and how to choose the best cross sec.
I’ve got a plot at the Community Garden, about a 10 minute drive from my house. Towards mid-summer, the well at the Community Garden runs dry. I’d like to collect rain water from my roof, and transport it to the Community Gardens.
Most of the rain barrels I’ve seen hold ~40+ gallons, which means 330+ of weight…a pretty heavy load to lift into the back of my mini-van. The good news is that if I can get a rain barrel or similar device into the minivan, I won’t need to take it out. My plot is a little down hill from the access road, so my plan had been to keep the rain barrel in the minivan and water the garden directly from there.
Are there smaller, connectable units available that would do the trick? Any thoughts on how to get water into the minivan?

we have a small vegatable garden at the kids house…watering gets confusing with us checking on it and the kids wanting to help take care of it. I have heard that about 2″ a week is all it needs, is that correct? (tomatoes, squash, and peppers) bought a rain gauge but not sure if it registers exactly what they are all getting. Currently watering 1/2 hr each morning, too much or too little?? Thanks~!!
Sounds like too much to me. You can tell when your vegetable garden isn’t getting enough water, because the leaves will start to wilt a little bit when it gets too dry. I don’t know where you are located, but here in Dallas, I’ve only watered my tomatoes once or twice since I planted them a couple of weeks before Easter.
When you get into the hot summer, you might need to water your garden daily. It’s going to depend on the temperature, what kind of soil you have, etc.
Here’s a good general guide to watering from Texas A&M University.
The heads on some of my pop-up sprinklers are turning every time the system comes on. I’ll pull it up and realign the shaft so it’s spraying in the right direction again but a couple of days later it’s watering my neighbors car. Is there a fix or am I buying some new heads? Thanks, Eric
Sounds like a lot of good info available here.
I currently have a 1.5 HP. pump drawing canal water with a 5′ lift and pushing uphill about 3′. The canal is being treated for underwater grass every two weeks by the HOA. When they treat, the water cannot be used for three days.
To circumvent the problem during out-of-town trips, I was thinking of moving the 1.5 HP pump to the well head. I have no idea of the well depth, only that the suction pipe is 3/4 PVC. My plan was to tee off of the 3/4 well pipe with the 1.5 HP pump and leave the ¾ HP ‘house” pump in place.
One watering station has 20 heads, the others fewer, and has always had adequate flow and pressure. Moving the pump would add about 80′ to the sprinkler valves.
