Water Storage Bladder, 100 Gallon Heavy Duty Food-Grade Plastic Bag

Water Storage
FIXED VERIFIED STORAGE
82129393, 35 Gallon Blue Portable Stackable Water Storage Tank
A rigid tank is easier to label, protect, rotate, and integrate into a permanent household water plan than loose cases of bottles.
MODULAR CARRYABLE STORAGE
UPWOIGH 5 Gallon Camping Water Jug with Spigot, Military Green
Five gallons is heavy but still movable. Small modules let you isolate batches instead of risking one enormous reservoir.
Rainwater Collection
RAINWATER COLLECTION
WADEO Upgraded Rain Barrel Diverter Kit for 2x3 or 3x4 inch Downspouts
A roof can become a major catchment area, but collection hardware must be designed as a system rather than a bucket under a gutter.
ROOF DEBRIS CONTROL
Downspout Filter / Leaf Remover for 2x3 and 3x4 Downspouts
Leaves, insects, grit, and roof debris are easier to remove before they enter a barrel than after they begin decomposing inside it.
Wells & Groundwater Access
SHALLOW GROUNDWATER ACCESS
Durable Cast Iron Pitcher Pump Manual Suction Well Pump — 25 ft Maximum Lift
A private well that depends entirely on electric pumping can become useless during a long blackout.
SHALLOW-WELL HARDWARE
Stainless Steel Water Well Point Drive Kit, 1-1/4 in Well Screen, 36 in, 60 Mesh
In suitable soils and where local rules allow, a driven well point can provide access to shallow groundwater without a conventional deep-well rig.
MEASURE BEFORE YOU PUMP
100-300M Portable Water Level Meter Sensor Deep Well Water Level Gauge — 100 m
Choosing a pump without knowing the static water level is guessing.
Prefiltration
VISUAL SOURCE SCREENING
Copkim 7.87 Inch Plastic Secchi Disk Set
Clarity is not safety, but turbidity matters because suspended material loads filters and can interfere with some disinfection methods.
COARSE PREFILTRATION
25 Micron Food Grade Nylon Tea Filter Bags, 2.5 x 4.5 in
A cheap sacrificial prefilter can keep sand, grit, algae, and visible debris from reaching a more expensive treatment stage.
SEDIMENT CONTROL
Membrane Solutions 20 Micron Pleated 10 x 4.5 in Whole House Sediment Cartridge
Sediment stages are serviceable and replaceable. They keep larger particles out of finer treatment systems and plumbing.
Treatment & Backup
PURIFIER REDUNDANCY
LifeStraw Max Replacement Ultrafilter Set
A serious system needs consumable and failure-point planning. Owning a purifier without replacement media is a single point of failure.
PERSONAL / MOBILE FILTER
Sawyer Products SP210
A household system can stay home. Every person still needs a compact way to handle questionable water during evacuation or field movement.
CHEMICAL DISINFECTION BACKUP
Water Purification Tablets — 100 Count
Filters can clog, pumps can break, and fuel can run out. A lightweight chemical backup gives the system another independent barrier.
DISTILLATION
VEVOR Water Distiller, 4L / 1.1 Gallon, 750W, Glass Carafe
Distillation solves a different problem from a backpacking filter and forces the prepper to think about dissolved contamination as well as microbes.
Testing & Monitoring
pH SCREENING
Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit
pH is an operational parameter that can reveal unusual changes and affects corrosion and treatment behavior.
TDS / CONDUCTIVITY SCREENING
HM Digital TDS-EZ Water Quality TDS Tester
A sudden shift from your normal TDS baseline can tell you that the water changed even when it still looks clear.
DISINFECTION CONTROL
Industrial Test Systems SenSafe 481026 Free Chlorine Test Strips
Chemical disinfection should not be reduced to 'I added some chlorine.' Measurement turns an improvised act into a controlled process.
MULTI-PARAMETER SCREENING
17-in-1 Complete Water Test Kit — Drinking Water
One box can help a household screen several common parameters and decide what needs a more specific test.
ALTERNATIVE SCREENING KIT
17-in-1 Complete Water Test Kit — Alternate Listing
A second listing gives the buyer an alternative when price, availability, or included tests differ.
RADIOLOGICAL SENTINEL
GQ GMC-800 Geiger Counter / Dosimeter
Radiation is invisible to human senses. A detector can warn that the environment or an object deserves immediate caution.
Sampling, Transfer & Access
CLEAN SAMPLING
Nasco Whirl-Pak B01064WA Write-On Sample Bags, 58 mL — Box of 500
A test result is only as trustworthy as the sample. Dirty cups and reused jars can contaminate a sample before testing even begins.
CLEAN-SIDE TRANSFER
Camco TastePURE Premium RV Drinking Water Hose, 50 Ft, 21009
A clean batch can be recontaminated after treatment. Transfer equipment belongs to the safe-water system, not the garden shed.
UTILITY ACCESS TOOL
HAUTMEC 4 Way Sillcock Water Key Set — 2 Pack
Some commercial or utility spigots use keyed valves. Knowing that such fittings exist is useful for your own property or authorized emergency access.
