Florida shallow well for lawn irrigation

[DMS]

Hi: I bought a home in the pinella's county area of Florida, it has town water and an existing well for lawn irrigation. The well has not been producing enough water. I'm not knowledgeable about wells, and am looking for advice on what to do. The previous owner said the well is 20 years old and has four points. He gave me an approximate location of the points, he's not sure how deep the points go. The well pump is about two years old. The lot size is approximately 10k feet, and there are seven zones of irrigation. The well pump seems to be set at 40 pounds of pressure. Some of the zones show 20 pounds of pressure when on, some other zones only show 10 pounds of pressure when on. I had a sprinkler/well guy over to take a look, he lives nearby. He thinks the low pressure is strictly because of low water output. He said he could go to the trouble of adding all new points, but said there was no guarantee on how long the new well would produce water, and recommended I either hook up the lawn irrigation system to town water, or look into having a deep well drilled. Both of those options are obviously very costly. It has been very dry lately, so it's possible that the water table will eventually come up a bit and maybe the irrigation system output will improve, but it's likely that a few of the zones still won't be producing enough water to properly operate the sprinkler heads.
Long story short, I'm thinking about either having all new points put in, or adding a couple points to the existing system if that's even possible, and wondered if anyone with experience could give me some input into the pros and cons of things. I might have another well person come by to take a look, it would be good to know exactly what I should be asking him. Thanks for any help

Yes, it has been fairly dry this winter In Florida and there is no magic to get a well working again.

Four points? Can't be very deep, maybe 20'. Other than a low water table, the points themselves could be clogged up. the only way to find them is start digging at the irrigation manifold or zone valve. What type of pump? Is it an irrigation pump or jet pump? There here are no pressure switches for an irrigation pump. Picture and model number could help. What size pump in HP? A 10k lot but how much of it is for turf? Once plants are established little water is needed but the turf does stress out especially if it's St. Augustine.

I would not waste money on new points since there is no way to know the depth and the water table. Seven zones tell me that it's a small pump. Irrigation pumps usually are 1, 1.5 or 2 HP. Pressure wise, zones with more heads will have lower pressure. I had a well installed in 1997 in Palm Beach Cointy. Up to 40 ft is shallow well but plenty of iron staining. My went down 83 feet and hit sulfur water. No iron stains and when it was on, it chased the kids away because of the stink. It was far cheaper than city water. At that time the well cost around $900. Pump about $150.

if you don't have the dollars for a new well, connecting to city water will be guaranteed that the system will work and not run out of water. However, a sprinkler guy probably will need to file a permit, changing things over to city water a backflow preventer will be needed. If you have a zone indexing valve, ditch it for a manifold. Indexing valves are hardly used anymore and replacement parts and new ones are harder to come by. A manifold takes a second to switch between zones where a zone indexing valve takes several minutes depending on the control you have.

With city water you'll need to watch that you don't over water because the water bill will be high. Here in Orange County, my monthly water bill is anywhere from $50-$70 per month and I'm on reclaimed water. If I do not irrigate the bill is around $55. Just the wife and I. I have a small yard, property is only 45x110 but about 1/3 of it is irrigated with four small zones.

If you get a well guy over, they usually are very knowledgeable of the water table in your area and what works best. Wells have become awfully expensive. you may already know that either on city water or your own well or lake, you're still restricted to the watering restrictions set by the water management district. Most are the same throughout the state.

WorthFlorida: Thanks for the reply, great info. Hooking up to town water is the easiest, but they get you for water coming in and water going out. My present monthly water bill is approx $50, but when you add the sewer charge it's over $100/month. Hooking up lawn irrigation to town water would double or triple that monthly bill. I'm not presently home but will post a couple pictures with more info when I get back.

Florida water is about the most expensive single item but with no state income tax and usually low property taxes, I'm not complaining. Switching over to city water it would be worth it to install a WiFi controller. I don't use automatic water every week but a few times usually during the winter since it's our dry season. Most of the raining season I'll rarely water. When the lawn starts to look stressed, I manually turn on a zone or do an entire irrigation program. Either away from home or on the patio, I can turn one the irrigation system. I have a Rain Bird Controller.

Sewer rates are capped at no more of a certain amount of water use. For Orange County Utilities it's 14,000 gallons. At $4.39/gallon plus the water itself at $1.81/gallon up to 10,000 gallons. Rate goes up per gallon over 10K.

You might have reclaimed water in your neighborhood. The crazy thing about it there is still water restrictions placed on reclaimed water. Makes no sense but then if it is enforced or not by the water district, not by the water utilities.

Florida's number one natural resource is water. There is some good information out there. https://floridadep.gov/water-policy/water-policy/content/water-management-districts

Have a well guy give you an estimate so you can make a decision if it's worth it than paying a higher monthly water bill.

Thanks for your info, very helpful. There's no reclaimed water in my area, not yet anyway. I'm in the Clearwater/Palm Harbor area, and plan on contacting local water department to try and get an idea on what my water bill might be with lawn irrigation tied into town water. We'll be doing the snowbird thing so the 'wifi controller' option sounds like a good idea if we go the town water route.

Attached couple pics of the well pump setup, it's a 'Pentair Sta-rite" model # SNE-L, 1 hp.

Would be easier to control the lawn watering needs if we lived here year round, but it is what it is. The 10k lot is all grass minus the imprint of a 1500 sf house/two car garage. The grass is St Augustine, recently had new sod installed in the backyard area, as well as all new bushes/ trees. But they're all mostly established as I've been watering them for two plus months.

If the town allowed the option of having two meters so I'd only be paying for water coming in and not paying for water going out then the decision would be easy.. as it appears the monthly sewer charge is even higher than the water charge.

Thanks for your replies,
