have heard lots of good things about dripworks, did you email them for their design assistance? this is probably a VERY busy time for them, so be patient

I use DripWorks products religiously. Their catalog is online. Getting a design started early is the key to getting personalized help from them.

If you have no luck with a response soon, I recommend you get their KROW starter system and build on that(KROW is the part number of the entire system). It is modestly priced and will get you started. It is also easy to understand and adaptable to many applications.

Once you get the gist of the system, you can build on it. Take some time this fall to sketch out your needs and DripWorks will customize a system tailored to fit your needs and resources.

I am waiting for a dripworks order right now. I used t-tape last year and liked it alot. The trouble is, I was only putting tape along main and secondaries. Now I think that water evenly across the whole patch is the way to go. I priced the expansion to my t-tap system (for 3000 square feet, less than half yours) and it was about 700-800. Because the total length of t-tape was a couple thousand feet, I needed 6 zones, which meant a fairly pricey timer. In the end, even though I really liked it, I am going with overhead (for a total cost of 100-200). I know there are possible issues with overhead, but I talked to a bunch of heavy hitters and many have always used overhead, so it can't be that bad. Water in the morning and do weekly sprays with milk.

Their web site is great.
Checkout info under farm or commercial uses.
They have a fill in the blank for some of the planning.
They also have a few diagrams.
Was with the NHGPGA last night very informative talk/demo
from Trevor Brookdale Farm, Hollis, on T-Tape drip system.
Really sounds good that you get even flow w/low pressure.

On line they listed 750' 15mil 12"on Center $80 per roll
4,100' 15mil 12"oc $225 per roll

I've got pretty low pressure down at my patch, and they list flow rates at 8 PSI. WOW!!

On-line Price less than $160 total to include: 750' roll, filter, pressure regulator, and a variety of fittings and shutoffs, I'm hoping to cover 6 plants working perpendicular to the Main, in 4-5 (shutoff) zones.
I'm also going to have overhead sprinklers 3 loc.

The amount of time I spent hand watering last year, this would be better than a 2yr old Big, Heaping Steaming Pile of
lobster manicotti.

Also thanks to George Hamilton who spoke, at the Demers Garden Center,Manchester, on soil sample testing and has been tracking area growers for a while out of UNH.

Some thoughts...

I can't figure out how you would do it for $160. I am using the prices from last fall because I am too lazy to look up the new ones, but they won't be far off.

If you only have 8 psi to work with, the longest run you can do is 280' at .45 gpm and 550 at .22 gpm, but .22 gpm is nothing. Lets assume your plot (40x30) has tape from one end to another every foot, you would need a total of 1200 feet.

Given 6 plants, go with 200' per plant. At the fastest rate (.45 gpm) you could go up to 280 feet which works...one zone per plant. Or, since 250 gallons is too much for 1 plant in a day, likely, go with the slower flow (.22gpm and get 550'...2 zones and empty the whole tank on the 2 plants). Of course, amount of water needed is dependent on the wetness of the soil, but we need to make some assumptions to figure this out. At .22 gpm, it would take 18.9 hours to use that water up.....

At .45 gpm, it would still take 9.2 hours...so there is a speed issue here. Reasonably you would want to water for no more than an hour or two (even 2 hours is long I would say) so that means that the drip tape would have to put out 2 gpm.

Lets assume 9 hours is reasonable and you will go with 3 zones, 2 plants per. I don't know how far your supply tap is, but for $12 I assume you need a '100 roll of 1/2 mainline. If you run separate lines from the timer for each zone you don't need shutoffs (the timer valves will handle this) otherwise, you need shutoffs and you also need to manually switch them so when the timer cycles to another zone, so the right valve is open and you don't rewater the same area.

100 ft of 1/2" mainline tubing - 12100    12.00
3 inline shutoffs - ELV12    1.95 ea        11.70
3 hose end connectors - ELFH 1.05 ea     3.15
2 750 T-Tape - T1508H7 74.00 ea     148.00

1 additional valve - TORV     15.50 ea 15.50

1 Miracle Punch - PUM 14.95 ea        14.95

That's $370 plus shipping and tax. So lets say $400.
