Public money should not buy Grade A for brine.
Municipal departments often specify a higher grade than the job needs. Brine, stormwater, dust suppression and hydrant flushing genuinely do not care about a stained wall, and the difference across a fleet is real budget that could be a pump, a trailer or more totes.
The short answer
Grade C reconditioned for de-icing brine, stormwater, dust suppression, hydrant flushing and street tree watering. Grade B where the public handles the unit. Documented food grade or rebottled for emergency drinking water — opaque-wrapped, dated and rotated on a schedule. Ask for documentation and check current regulations.
Applications
What public works actually runs.
| Application | Grade | Size | Gross weight, full, approx. | Notes |
|---|---|---|---|---|
| De-icing brine (about 23% NaCl) | Reconditioned C | 275 / 330 gal | 2,820 lb / 3,370 lb | Recirculate or agitate; undissolved salt settles |
| Emergency drinking water | Documented food grade / rebottled | 275 gal | 2,430 lb | Opaque wrap, date, rotate on schedule |
| Hydrant flushing & testing | Reconditioned C | 275 gal | 2,430 lb | Fit an inlet screen — hydrant water carries grit |
| Dust suppression | Reconditioned C | 275 / 330 gal | 2,430 lb / 2,900 lb | Skid-mount with a pump and a spray bar |
| Street tree & median watering | Reconditioned B or C | 275 gal | 2,430 lb | Gravity feed and a wand; wrap against algae |
| Stormwater sampling & holding | Reconditioned C | Small format / 275 gal | Varies by size | Small format is easier for sampling crews |
| Sewer jetting water | Reconditioned C | 330 gal | 2,900 lb | More water per trip; check truck capacity |
| Herbicide for ROW maintenance | Dedicated unit | 220 gal | Varies by product | Permanently dedicated. Never rotates back. |
| Pool / facility chemical storage | Reconditioned A | 275 gal | Varies | Check oxidiser compatibility and venting |
Brine, done properly
De-icing brine is a high-volume municipal tote application in cold-winter regions, and it has two failure modes worth planning around.
Concentration drifts
Road brine is usually made close to 23.3% salt, the concentration with the lowest freezing point (about −6°F). Brine made weaker freezes sooner; brine made stronger can drop salt as it cools, and undissolved salt settles in a still tank. Either way you end up applying something other than what you think. Check concentration with a hydrometer or salinity meter and recirculate before use.
Grit in the valve
Brine made on site carries undissolved solids. Those find the valve seat and keep it from closing fully, which you discover as a slow leak across a yard in January. Fit a screen at the fill point and keep spare seats on hand.
Emergency water stock
Municipal emergency water stockpiles are one of the few places worth spending up. Rebottled units remove the prior-contents argument entirely, which matters when the stock is deployed in a situation where nobody has time to check documentation. Ask the supplier for the documentation in advance, keep it with the plan, and check current regulations.
Wrap them opaque, stencil the fill date on the cage, and rotate on a defined schedule. Water keeps far better in a dark, cool, sealed food-grade container than in a translucent tote in a sunny bay.
Procurement notes
Several things about municipal purchasing make this category different. These are the things buyers typically ask partner suppliers for.
- Written quotes that survive a committee. Ask for grade definitions, unit pricing and freight broken out, in a form you can attach to a requisition.
- Grade definitions in writing. Grade names are not standardised, so ask each supplier for its written A/B/C criteria and reference them in the specification rather than relying on adjectives.
- Repurchase of empties. Ask whether the supplier will buy back usable units at end of service, so the department is not left with a disposal cost.
- Split deliveries. Yard space is usually the constraint. Ask whether delivery can be staged against a schedule.
- Everything in writing. A written request through our quote form suits a procurement file better than a conversation anyone would have to summarise later.
What grade criteria usually cover, and how to write them into a spec.

Application rates vary by agency, storm and road. These example rates show the arithmetic; use your own agency's guidance.
| Application | Example rate | One 275 treats | One 330 treats |
|---|---|---|---|
| Anti-icing, pre-treatment | 40 gal / lane mile | 6.9 lane miles | 8.3 lane miles |
| Anti-icing, heavy | 60 gal / lane mile | 4.6 lane miles | 5.5 lane miles |
| Pre-wetting salt at the spinner | 8 gal / ton | 34 tons | 41 tons |
| Sidewalk and plaza | 25 gal / 1,000 sq ft | 11,000 sq ft | 13,200 sq ft |
| Bridge deck | 50 gal / lane mile | 5.5 lane miles | 6.6 lane miles |
Emergency water
Specifying an emergency water stockpile.
One of the few places worth spending up. Deployment is not a moment for anybody to be checking documentation, so settle it at purchase.
| Requirement | What buyers typically ask for | Why |
|---|---|---|
| Container | Rebottled, with the bottle manufacturer's food-contact documentation | Removes the prior-contents question |
| Gasket | New EPDM throughout | Food-contact surface; never reuse |
| Cap | Solid with a tamper-evident seal | Shows at a glance whether a unit has been opened |
| Wrap | Opaque UV sleeve | Algae need very little light; HDPE is translucent |
| Marking | Fill date stencilled on the cage | Rotation happens if the date is visible |
| Storage | Indoors, cool, dark | Water keeps better dark, cool and sealed |
| Rotation | A defined schedule in the plan | Set it in the plan, not in somebody's memory |
| Dispensing | Dedicated food-grade hose, stored with the unit | A hose off a truck defeats the whole exercise |
| Documentation | Held with the emergency plan | Nobody will find it in a filing cabinet during an incident |
Procurement
Writing a specification that gets you the right containers.
Municipal purchasing has constraints that make this category awkward. These are the clauses that produce a comparable set of bids.
| Clause | Write | Rather than | Why |
|---|---|---|---|
| Grade | Reference written grade criteria | "Good condition" | Grade is not standardised; adjectives are unbiddable |
| Condition | State the application and let bidders propose | Specify Grade A by default | Brine does not need Grade A |
| Freight | Quoted as a separate line | Delivered price only | You cannot compare a buried number |
| Hardware | New valve seat and cap gasket on every unit | Silent | Not every supplier replaces these |
| Testing | Leak test on every unit | Silent | The difference between washed and tested |
| Documentation | Prior-contents record where it exists | "Clean" with no detail | Cleaned by whom, against what |
| Photographs | Of the actual lot, before payment | Silent | Eliminates a common dispute |
| Warranty | Bidder states what is covered, in writing | Silent | Otherwise replacement is at your cost |
| Delivery | Split release against a schedule | One delivery | Yard space is usually the real constraint |
| Repurchase | Bidder states any buyback of empties | Disposal at your cost | Turns a disposal line into a residual |

Municipal questions
Can we store emergency drinking water in used IBC totes?
Only in documented food-grade or rebottled units, and they should be opaque-wrapped, dated and rotated on a schedule. A tote that held an unknown industrial product is not an emergency drinking-water container regardless of how well it was washed. Buyers in this sector typically ask partner suppliers for rebottled units, because a new bottle removes the prior-contents question. Ask for the bottle manufacturer's food-contact documentation and check current state drinking-water regulations.
Are totes good for de-icing brine?
Very, and it is one of the most common municipal uses. Sodium chloride road brine at around 23% is about SG 1.17, so a full 275 comes in at roughly 2,820 lb gross. Brine is compatible with HDPE and EPDM. Grade C reconditioned is usually adequate — brine does not care what the wall looks like — and the difference adds up across a fleet.
What grade should a public works department buy?
Grade C for brine, stormwater, dust suppression, hydrant flushing and street tree watering. Grade B where the unit is customer-facing or will be handled by the public. Documented food grade or rebottled for anything people drink. Buying Grade A across a municipal fleet is a common and expensive habit that nothing in the application justifies.
Do totes work for street tree and median watering?
Very well, and they are common kit for urban forestry crews. A 275 on a flatbed with a gravity feed and a wand handles a run of street trees efficiently — check the truck's payload first. Wrap the tank, since algae grow quickly in a clear tote in summer sun, and fit a screen at the fill point because hydrant water carries grit.
