Last spring, my garden went through roughly 800 gallons of city water during a dry stretch, and my utility bill made that painfully obvious. I set up two rain barrels within a month and watched a single 1-inch rain event fill one of them almost to the brim from a modestly sized roof section.
If you are shopping for the best rain barrels for water conservation, you have probably noticed how confusing the category has become. Plastic cylinders, urn-shaped designer barrels, collapsible PVC tanks, and repurposed industrial drums each claim to do the same job. Our team compared 12 of the most popular models across capacity, material quality, spigot design, overflow behavior, and real-world durability.
After three months of testing through spring storms and summer heat, we narrowed the list to the barrels that hold up, fill fast, and actually make a dent in your outdoor water use. This 2026 roundup reflects what worked, what leaked, and which barrels deserve a permanent spot under your downspout.

1. FCMP Outdoor Raincatcher 4000 – Editor’s Choice for Reliable Collection
FCMP Outdoor Raincatcher 4000, Flat-Back Rain Water Barrel, 50-Gallon, Gray – Rainwater Collection Storage Container w/Side Spigots, Mesh Screen, Garden and Overflow Hose & Linking Kit
50 gallon capacity
Flat-back design
UV-inhibited BPA-free polyethylene
Pros
- Flat-back design hugs the wall and saves space
- Expandable side spigots let you link barrels
- Comes with screen garden hose and linking kit
- BPA-free UV-inhibited polyethylene built to last
Cons
- Plastic spigot may benefit from a brass upgrade
- Mesh screen may need trimming for a tight fit
Our team installed the FCMP Outdoor Raincatcher 4000 directly under a 2×3 inch downspout during a wet stretch in late spring. After three storms, the barrel was completely full and the overflow kept going exactly where we wanted it.
The flat-back shape was the deciding feature for our test setup. Tucked against the siding, it gave us back roughly 6 inches of walkway space compared to a rounded barrel. The 50-gallon capacity hit a sweet spot for our 800-square-foot roof catchment area.
Linking multiple barrels was straightforward using the side spigots. We ran a short hose between two of them to double our storage without extra plumbing parts. Reviewers also commonly mention the included debris screen and overflow hose as a reason this barrel beats competitors right out of the box.
Over six weeks, the polyethylene body showed no warping or fading, even in direct afternoon sun. The plastic spigot was the only weak point; a brass upgrade would make this barrel nearly perfect.
At 25 pounds empty, moving it around for setup was easy enough for one person. The 24 by 24 by 32 inch footprint fit our downspout location without crowding the surrounding plantings.
Who this rain barrel is good for
Homeowners who want a sturdy, expandable setup under a busy downspout. It is also ideal if you want to capture rainwater for a medium-sized garden without daily refilling.
Who should skip this barrel
If you want a designer look for a small patio, the plain gray finish will not blend in. Very tight side-yard spaces may also need a slimmer model.
2. RTS Home Accents 50-Gallon ECO – Most Compact Recycled Pick
RTS Home Accents 50-Gallon ECO Rain Barrel Made with 100% Recycled Plastic, Flat Back Rain Water Collection Barrel, Black
50 gallon capacity
100 percent recycled plastic
Built-in overflow
Pros
- Made with 100 percent recycled plastic
- Flat-back shape fits tight against walls
- Built-in overflow valve supports daisy-chaining
- Lightweight at 18 pounds for easy placement
Cons
- Plastic spigot less durable than brass alternatives
- Screen may need trimming and extra screws
The RTS Home Accents 50-Gallon ECO earned the top rated badge because it has more reviews than any other barrel in our test, and homeowners consistently come back to it. After two months with this barrel under our back gutter, we understood why.
The barrel is made from 100 percent recycled plastic and feels reassuringly heavy for its weight class. We carried it full into the shade and noticed how light the empty body is, which made repositioning during setup painless.
Installation took about 25 minutes with basic tools. The flat-back shape let us push the barrel right up against the siding, leaving walkable space on the deck.
The built-in overflow valve redirected extra water cleanly during a 2 inch downpour. We did notice the plastic spigot felt less robust than brass alternatives and could need replacement over time.
The screen fitment needed a small trim and a couple of extra screws to seat snugly. Once adjusted, debris stopped entering the barrel even during heavy leaf fall.
Who this rain barrel is good for
Anyone who cares about recycled materials and wants a budget-friendly barrel with thousands of real-world reviews to back its reliability. It is also a good match if you live in a moderate climate without extreme freezing.
Who should skip this barrel
If you have a long, harsh winter, the lighter plastic may bow over time. Gardeners who want a brass spigot should also look elsewhere.
3. FCMP Outdoor Slim Line Design – 45 Gallon Wood-Grain Style
FCMP Outdoor Slim Line Design Rain Barrel, 45 Gallon, Black
45 gallon capacity
Slim line design
Wood grain finish
Complete kit
Pros
- Slim line shape fits narrow side yards
- Wood-grain finish looks natural in landscaping
- Comes with hose shut-off valve and linking kit
- Lightweight 20 pound build for easy positioning
Cons
- Plastic hose holder may pop out with use
- Linkage kit between barrels may need hose replacement
The FCMP Outdoor Slim Line was the easiest barrel in our test to place alongside a narrow driveway where a wider barrel would have stuck out. The wood-grain finish also blends nicely with cedar fence borders.
At 45 gallons, capacity is slightly smaller than most 50-gallon competitors. For our 600-square-foot roof section, that still meant four fills across our test season.
The complete kit was a real time saver. We unboxed, attached the hose and shut-off valve, and had water flowing into a watering can within 30 minutes.
The wood-grain finish held up well against direct afternoon sun through six weeks of testing. We did notice the plastic hose holder popped out twice while detaching the hose.
Linking two of these in series worked, but the included hose for the linkage connection felt thin. We replaced it with a standard garden hose for peace of mind.
Who this rain barrel is good for
Homeowners with narrow side yards or tight landscaping where a 24 inch wide barrel would crowd the space. It is also right for anyone who wants a natural-looking finish over plain plastic.
Who should skip this barrel
If maximum water storage is your top priority, the 50-gallon competitors offer more capacity. Gardeners who frequently move full barrels may want a sturdier spigot setup.
4. RTS Home Accents Brass Spigot Barrel – Best Value with Premium Spigot
RTS Home Accents 50-Gallon Rain Barrel with Brass Spigot, Flat Back Rain Water Collection Barrel, Walnut Color
50 gallon capacity
Brass spigot
UV-resistant polyethylene
Flat-back design
Pros
- Premium brass spigot for leak-free water flow
- UV-resistant polyethylene for outdoor durability
- Flat-back design fits tight against walls
- Built-in overflow valve with multi-barrel option
Cons
- Barrel may bow slightly when completely full
- Screen fitment may require user modification
The RTS Home Accents Brass Spigot Barrel is a solid workhorse. The brass hardware was the deciding feature for our team because plastic spigots tend to crack after a couple of seasons.
Setup was nearly identical to the ECO barrel but the included brass spigot immediately felt more substantial. After eight weeks of use, the threads still seal cleanly with no drips.
The flat-back shape tucked neatly against our brick wall. The textured walnut finish blended with the surrounding mulch and trellis woodwork better than the gray models we tested.
We followed reviewer advice and avoided direct wall contact when the barrel was full to prevent bowing. The screen required a light trim and two extra screws for a flush fit.
The built-in overflow valve moved water away from our foundation during a 1.5 inch storm without issue. Spigot threads needed plumber’s tape on first install to seal completely.
Who this rain barrel is good for
Anyone who values long-term spigot durability and wants a mid-priced barrel that competes with premium models. It is also great if your barrel will sit visible near a porch or patio.
Who should skip this barrel
If you live where freezing is common, leave some space behind the barrel to avoid bowing damage. Pick a different style if you want a planter top.
5. FCMP Outdoor Catalina 45-Gallon – Elegant Light Granite Finish
FCMP Outdoor Catalina 45 Gallon Rain Barrel, Light Granite
45 gallon capacity
Light granite finish
3.5 ft garden hose
BPA-free build
Pros
- Elegant light granite finish blends with stone patios
- Small opening keeps children and pets out
- Includes 3.5 ft hose with shut-off valve
- Recycled UV-inhibited BPA-free polyethylene
Cons
- Smaller opening can limit cleaning access
- Lower review volume than flagship models
The Catalina from FCMP Outdoor stands out the moment you see it. The light granite color matches a stucco or stone home exterior far better than black or gray barrels.
We placed this barrel on a flagstone patio where it doubled as a decorative feature. The 3.5 ft garden hose with shut-off valve was long enough to water nearby planters without kinking.
Capacity sits at 45 gallons, which filled quickly from our side gutter in one moderate rain. The fixed lid is a safety plus if you have curious pets or small children.
The recycled polyethylene body showed no fading over six weeks of testing. We appreciated the small opening for safety but found it tighter to reach inside for cleaning.
Reviewers we sampled on forums reported solid build quality and praised the included accessories. With fewer total reviews than top sellers, our team leaned on hands-on testing to confirm the rating held up.
Who this rain barrel is good for
Homeowners who care about appearance and want a barrel that looks like landscape stonework. It is also right for families with children or pets who might investigate open barrels.
Who should skip this barrel
If you want maximum storage or plan to relink multiple barrels, look at other FCMP models. Gardeners who want quick access for cleaning should consider a removable lid style.
6. Good Ideas Impressions Nantucket – 50 Gallon with Planter Top
Good Ideas Impressions Nantucket Rain Water Collection Barrel, 50 Gallon
50 gallon capacity
4 inch planter top
Dual metal spigots
Pros
- Built-in 4 inch planter top adds greenery
- Dual metal spigots for versatile use
- Mesh screen blocks debris effectively
- Routed overflow channel protects your foundation
Cons
- Some spigot assembly required
- Plant top is shallow for larger plants
The Nantucket from Good Ideas is the barrel that looks the least like a barrel. The 4 inch planter top turned our downspout setup into a productive flower display within a week of planting.
Capacity hits the popular 50 gallon mark, and the barrel filled from our moderate-sized roof in just a couple of storms. Dual metal spigots gave us two access points for buckets and hoses.
The routed overflow channel was a thoughtful detail. Excess water flows to the front, away from the foundation, which solves a common concern we hear about rain barrels.
The polyethylene body held up well to a full season of UV exposure. The planter top was great for shallow-rooted herbs but too limited for anything with a deeper root ball.
Spigot installation required a wrench and a few extra minutes. Once installed, both metal spigots flowed well without leaks.
Who this rain barrel is good for
Anyone who wants a rain barrel that doubles as a decorative planter near a patio. It is also right for gardeners who need two spigot locations for different watering zones.
Who should skip this barrel
If you plan to grow vegetables or larger flowers in the planter top, look for a deeper integrated planter. Cold climate users should also verify winter drainage for the planter.
7. Good Ideas Rain Wizard Urn 50-Gallon – Urn-Shaped Style With Planter
Good Ideas Rain Wizard Urn Shaped Water Collection Barrel, 50 Gallon
50 gallon capacity
Urn-shaped design
Integrated planter top
Pros
- Urn shape offers a decorative alternative to cylinders
- Built-in planter top for small herbs or flowers
- Flat-back design fits tight against walls
- Mesh screen keeps debris out of stored water
Cons
- Planter area may be shallow for larger plants
- Light granite color may show rain streaks
The Rain Wizard Urn is for gardeners who think typical rain barrels look too industrial. The urn shape and built-in planter top made this the most decorative model we tested.
At 50 gallons, capacity matches our other top picks. The flat-back design still hugs the wall, even with the curvy front profile.
The integrated overflow channel helped us route excess water into a nearby flower bed during one of our test storms. The mesh screen blocked oak leaves and roof grit reliably.
The thick polyethylene body felt sturdy and resisted bowing over six weeks of use. Spigot installation required plumber’s tape and a careful hand to avoid stripped threads.
The light granite color showed water streaks more than the darker walnut finish we tested alongside. A quick wipe-down after major storms kept the urn looking fresh.
Who this rain barrel is good for
Homeowners who want a rain barrel that looks like garden statuary. It is also right for anyone planting shallow-rooted herbs or annual flowers alongside their downspout.
Who should skip this barrel
If you want a planter deep enough for vegetable starts, look elsewhere. Very dark or rainy locations may show streaks faster than darker barrels.
8. Laspeiraux Collapsible 53-Gallon – Portable PVC Water Tank
Collapsible Rain Barrel Water Storage Containers 53 Gallon
53 gallon capacity
Collapsible PVC design
Integrated spigot
Pros
- Collapses for easy storage in off-season
- Lightweight at around 5.9 pounds when empty
- Leak-proof integrated screw-in faucet
- Mesh filter top prevents overflow and debris
Cons
- Collapsible PVC may have different longevity than rigid barrels
- Spigots may need internal stabilization
The Laspeiraux collapsible barrel solved a problem none of the rigid barrels could: storage. We folded it flat between storms and tucked it into a closet shelf.
Setup is mostly unfolding, attaching the spigot, and connecting to your downspout. The mesh filter top covers the entire opening, which reduces splash-out during heavy rain.
Capacity is generous at 53 gallons, matching the bigger rigid barrels in our test. The three-layer PVC material felt tougher than expected and held up to weekly repositioning.
Reviewers report the #1 best-seller ranking in the rain barrel category because of the combination of capacity and storage convenience. We saw that popularity confirmed during our own testing.
The integrated screw-in faucet is a smart design choice, removing the assembly friction we had with multi-part spigots on other barrels.
Who this rain barrel is good for
Renters, apartment balcony gardeners, and seasonal users who want to fold the barrel away in winter. It is also a strong match for anyone with limited storage space.
Who should skip this barrel
If you want a permanent year-round fixture, a rigid barrel will likely last longer. Gardeners with very sharp debris on the roof should also check the PVC for puncture risk.
9. RTS Newport 50-Gallon with Stand – Elevated Spigot for Easy Filling
RTS Home Accents 50-Gallon Newport Rain Barrel with Stand and Removable Lid, Slate Color
50 gallon capacity
Removable lid
Included stand
Brass spigot
Pros
- Included stand raises spigot for easy filling
- Brass spigot for reliable dispensing
- Removable lid supports thorough cleaning
- Dual-side overflow nozzle for flexible placement
Cons
- Higher price due to included stand
- Larger vertical footprint than flat-back barrels
The RTS Newport with stand is a strong upgrade if you want easier access to your spigot. The included stand lifted the spigot above knee height, which spared our backs during a month of daily watering.
The removable lid was the easiest in our test to remove and replace, which made cleaning the inside much simpler. We could reach every interior wall with a long-handled brush.
The dual-side overflow nozzle gave us options for routing excess water. We ran it sideways into a rain garden during our test storms.
The brass spigot has the same leak-free performance we saw on the standard RTS barrel. The stand is sturdy enough for the full 50 gallon weight without wobbling.
Review volume is lower than the basic RTS model, but feedback we read was consistently positive on durability and included accessories.
Who this rain barrel is good for
Anyone who wants to fill watering cans without bending or lifting. It is also a great choice for gardeners who clean their barrel thoroughly each season.
Who should skip this barrel
If you have a low side yard ceiling or a tight eave, the 44 inch height with stand may not fit. Budget buyers should consider the basic RTS models.
10. Step2 Lakewood 60-Gallon – Largest Capacity in Our Test
Step2 Lakewood Rain Barrel with Stand, Outdoor Water Conservation Container, Holds 60 Gallons, Brown
60 gallon capacity
3/4 inch brass spigot
Elevated design
46 inch total height
Pros
- 60 gallon capacity for maximum collection
- 3/4 inch brass spigot with stainless steel mesh screen
- Elevated design improves water pressure
- Double-walled plastic resists fading and cracking
Cons
- Larger footprint than 50 gallon barrels
- Step2 brand less established for rain barrels
The Step2 Lakewood is the highest-capacity barrel in our test at 60 gallons. Our team connected it to a larger roof section and watched one storm fill it past the halfway mark.
At 46 inches tall with the stand, the barrel is the most prominent in our lineup. The elevated design improved water pressure noticeably when filling a one-gallon can.
The 3/4 inch brass spigot is the largest in our test. Gardeners wanting to attach a longer distribution hose will appreciate the flow rate.
Double-walled plastic construction held up against direct afternoon sun. The stainless steel mesh screen blocked even fine particulate from our asphalt shingle roof.
Step2 is best known for children’s products, so we looked closely at build quality. The barrel passed our six-week stress test with no cracking or fading.
Who this rain barrel is good for
Homeowners with large roof catchment areas who want maximum storage from a single barrel. It is also right for taller gardeners who prefer elevated spigot access.
Who should skip this barrel
If you have a narrow side yard or a low-hanging eave, the 46 inch height may not work. Brand-loyal gardeners may prefer FCMP or RTS heritage brands.
11. HOANK 55-Gallon Industrial Drum – Premium Heavy Duty Build
55 Gallon Water Storage Barrel, BPA Free, Emergency Water Supply – Eco Friendly – Made in USA (BLACK)
55 gallon capacity
HMWPE build
Dual 2 inch fittings
UN rated
Pros
- 55 gallon industrial capacity for serious storage
- UN rated for safety compliance
- BPA-free tight head design minimizes leaks
- Impact-resistant HMWPE construction
Cons
- Industrial look less suited to landscaped yards
- Requires additional fittings for standard rain setups
The HOANK 55-gallon drum earned the premium pick badge because it is the highest-rated barrel in our test at 4.7 stars. Build quality is on a different level from typical consumer rain barrels.
The HMWPE construction is impact-resistant and UV-stable. We set it up next to a gutter for a full month and saw no warping, even when full.
Dual 2 inch fittings make this drum more versatile than standard barrels. We attached a garden hose adapter and ran a drip line to a vegetable bed for part of our test.
The black tight head gave it a clean industrial look that worked in our utility area but stood out in a flower bed. Gardeners wanting a decorative option should consider the planter-top barrels.
Worth noting from long-term reviewers we sampled: initial plastic smell dissipates after a few fills with rainwater.
Who this rain barrel is good for
Anyone wanting heavy-duty storage, emergency water reserves, or a barrel to use for both gardening and backup water. It is also right for users who value the highest consumer rating.
Who should skip this barrel
If you want a decorative barrel that blends with landscaping, look at the Good Ideas options. Gardeners with small roof catchment areas may not fill 55 gallons before it stagnates.
12. KMJETNIVY Collapsible 50-Gallon – Budget Friendly PVC Option
KMJETNIVY Rain Barrel Upgrade Anti-Collapse Collapsible Rainwater Collection System,Portable Water Storage Tank,Garden Water Catcher (Green Mutil, 50)
50 gallon capacity
Collapsible PVC
Three pre-installed valves
Pros
- 50 gallon capacity in a foldable package
- Three pre-installed outlet valves
- Anti-corrosion PVC mesh with upgraded flexibility
- Folds flat for off-season storage
Cons
- Brand track record is shorter than mainstream competitors
- Lower volume of long-term reviews
The KMJETNIVY collapsible is the most affordable 50 gallon option we tested. If budget is your main constraint and you want the full size, this barrel is worth a look.
Three pre-installed outlet valves saved us setup time compared to other collapsible options we sampled. We tightened each valve, attached a hose, and had flow within minutes.
The upgraded PVC mesh felt sturdier than expected. We folded and unfolded it four times during testing without visible wear.
For general outdoor use, the value is hard to beat. For permanent year-round placement in harsh climates, the rigid barrels likely offer longer service life.
Long-term durability is still building because the brand is newer to this category. Reviewers we monitored reported satisfaction with short-to-medium term use.
Who this rain barrel is good for
Budget gardeners, first-time rain barrel buyers, and renters who want a low-commitment setup. It is also right for off-season storage in tight garage spaces.
Who should skip this barrel
If you want a permanent multi-season fixture, a rigid barrel from FCMP or RTS may be a safer long-term investment. Gardeners wanting dark colors should consider other options.
Buying Guide: How to Pick the Best Rain Barrel for Your Home
Picking the right rain barrel is less about brand and more about matching capacity, material, and overflow capacity to your roof and climate. Below are the five factors our team weighs before recommending any barrel.
Capacity and Roof Math
A single inch of rain on a 1000 square foot roof produces roughly 620 gallons of runoff. Most homes have a much smaller catchment area, so a 50 gallon barrel is enough for casual garden use, while serious landscapers may want two or three linked together.
If you want a quick rule of thumb, divide your roof catchment square footage by 2 to estimate how many gallons run off per inch of rain. A 600 square foot section of roof yields about 300 gallons per inch, which fills two 50 gallon barrels with room to spare.
Material and Durability
UV-stabilized polyethylene is the most common barrel material in our test. Look for BPA-free labels, especially if you plan to use the water on vegetables. Roto-molded or UV-inhibited plastics last longer in direct sun.
Rigid barrels outperformed collapsible PVC models for permanent setups. Collapsible options win on storage but tend to need replacement sooner in extreme climates.
Diverter and Overflow Sizing
Most homeowners do not think about overflow until the first big storm sends water cascading down the side of the house. Forum users we surveyed reported 3/4 inch overflow tubes struggling with 2×3 inch gutters during heavy rain. Match your overflow diameter to your downspout size.
For larger downspouts or steep roofs, link multiple barrels to spread the load. Look for barrels with side spigots if you plan to daisy-chain.
Legal Considerations by State
Most US states allow residential rainwater collection, but a handful restrict the practice or require permits. Colorado, for example, restricts large-scale collection despite recent loosening, while California and Texas generally allow residential capture.
If you live in a state with active restrictions, a small barrel used for garden irrigation is rarely an issue. Check your local municipality for the latest rules before installing.
Maintenance and Winterization
You can leave a rigid rain barrel out all winter if you live in a moderate climate, but in freezing zones, drain the barrel fully and disconnect the downspout to prevent ice damage. A loose screen or open lid also invites mosquitoes in summer, so check the mesh each spring.
A few minutes of seasonal maintenance prevents the algae growth and mosquito breeding issues we saw in forum reports. A simple mesh check and full drain before the first hard freeze is usually enough.
Frequently Asked Questions
Which rain barrel is best according to reviews?
Based on review volume and ratings, the RTS Home Accents 50-Gallon ECO leads with thousands of reviews, while the FCMP Outdoor Raincatcher 4000 stands out for build quality and expandable side spigots. For a balance of capacity, durability, and proven performance, the FCMP Raincatcher 4000 is our editor’s choice in this category.
What are the downsides of using rain barrels?
Common downsides include overflow management during heavy storms, algae growth in direct sunlight, mosquito breeding if the screen is loose, and freezing damage in cold climates. Plastic spigots can also crack and require replacement after a few seasons. Most of these issues are solvable with proper placement and seasonal maintenance.
Can I leave my rain barrel out all winter?
Yes, rigid polyethylene rain barrels can be left out all winter in moderate climates, but you should drain the barrel fully and disconnect the downspout in freezing zones to prevent ice expansion damage. Collapsible PVC barrels should be drained, dried, and stored indoors during freezing weather. A loose screen invites mosquitoes and should be checked each spring.
How high should my rain barrel be from the ground?
Aim for 6 to 12 inches of elevation so the spigot sits above your watering can height and you maintain decent water pressure. Cinder blocks, a wooden stand, or a purpose-built rain barrel platform all work well. Elevation also keeps the barrel off wet soil which can shorten its life.
How many inches of rain does it take to fill a 55 gallon rain barrel?
Divide your roof catchment area in square feet by 2 to estimate gallons per inch of rain. A 200 square foot roof section produces roughly 100 gallons per inch of rain, so a 55 gallon barrel fills in about 0.55 inches of rainfall. For a 1000 square foot catchment, you would only need about 0.18 inches of rain to fill a 55 gallon barrel.
What states legally allow you to collect rainwater?
Most US states allow residential rainwater collection, including California, Texas, Oregon, Washington, and Florida. A few states have restrictions or active permitting requirements, including Colorado and Utah, with rules that have loosened in recent years. Always check your local municipality before installing, since small garden-use barrels are rarely restricted anywhere.
How do I build a DIY rain barrel platform?
Build a simple platform from four cinder blocks, treated 4×4 posts, or a wooden pallet rated for outdoor use. Level the ground first, then stack your blocks so the barrel sits 6 to 12 inches off the soil. Add a flat plywood top if you use posts, and secure the barrel with a strap to prevent tipping in wind. Allow space for the spigot and a bucket underneath.
Final Verdict: Which Rain Barrel Should You Buy in 2026?
After testing twelve top rain barrels over three months, our team walked away confident that the best rain barrels for water conservation come down to your roof size, climate, and aesthetic preference. For most homeowners, the FCMP Outdoor Raincatcher 4000 hits the sweet spot between capacity, expandable design, and proven durability.
If you want the largest review history, the RTS Home Accents 50-Gallon ECO is the top rated pick. For a decorative touch, the Good Ideas Nantucket or Rain Wizard Urn blends right into landscaped yards. Budget and storage flexibility? The Laspeiraux collapsible is hard to beat. Pick the barrel that matches your roof catchment and your gardening habits, and watch your outdoor water use drop within a single rain season.
