How would you design this system?

    Hi all,

    I operate a car wash and I want to get these two pieces of landscaping irrigated. The small island has 3 young pampas grass plants. We may plant ornamental grasses around it but for right now, these are the only plants going inside it.

    The second island is around our garbage bin and right next to our pay stations.

    I would like this designed to where we have the least amount of overspray as possible. I would also like to stick to Rain Bird products. We have a regular customer that comes in that said Rain Bird is the way to go but he wants $75 to design the layout. While I don't think this is excessive by any means, I would much rather get a couple of opinions on here.

    Please be specific with how you would design this (PVC, hookups, model numbers). I don't want anything fancy like timers or anything electric. I have never designed an irrigation system but I'm sure I could with the right guidance. I have just purchased an irrigation book published by Lowe's so I will be reading up on it.

    BTW - I don't need to be bashed so keep it to yourself. I just want some good information. I've been browsing this forum and there is a bunch of good information floating around. I've also seen a bunch of immature bashing which is not what I'm here for :nono:

    I can get you any additional information you need such as measurements and more pictures. I will test my GPH tomorrow.

    Ok, I measured exactly 5 gallons in a 5 gal bucket and marked it. It took about 38 seconds to fill. So is my GPM around 8? 300/38 = 7.89

    Do you think this would be enough pressure to handle these two small areas? I will run one island at a time.

    That's plenty for Netafim; pressure is not a problem. I believe all Netafim is pressure-compensating these days. A filter downstream
    of your backflow preventer is suggested; make sure you provide enough room to service the filter.

    Throw the guy a quick $75 and have him include a parts list for ya. His price is more then resonable.

    The source is city water, not reclaim. Had a problem with sulfur smell and corrosion in our pipes so we ditched the reclaim water idea for now. Here is our faucet. If you look closely, you will see the pampas grass island in the red box that I marked. Sorry I couldn't get a good picture of both because of the lighting but you get the idea. I would like to hook up the water hose to the main sprinkler inlet. Am I missing something here? Valve? Then have a separate hose hookup at each island and let them run at different times. This is possible right? I don't really want to hook them both up to where both islands are irrigated at once.

    All ideas welcome.

    Just trying to get this irrigated because we've been hand watering. Spending too much labor $$$ plus it looks good to customers.
