Concrete Batch Plant Water Supply: Tank Selection and Installation Guide
Concrete Batch Plant Water Supply
Concrete batch plants consume large volumes of water — 25 to 40 gallons per cubic yard of concrete produced. A mid-size plant producing 200 yards per day needs 5,000-8,000 gallons of process water daily, plus washout water for trucks, equipment, and the plant itself. Reliable water storage is critical because any interruption in water supply shuts down the entire plant.
Why Tank Selection Matters for Concrete Batch Plant Water Supply
Not every polyethylene tank works for every application. The wrong tank can mean chemical incompatibility, premature failure, regulatory violations, or simply wasted money on features you don't need. This guide walks you through the specific requirements for concrete batch plant water supply and matches you with the right tank from our catalog.
Key Requirements
- Volume — Size for at least one full day of production plus washout reserves. 10,000-gallon minimum for most operations.
- Fill Rate — The tank refill rate must exceed the plant's peak consumption rate. Size your supply line accordingly.
- Water Quality — Process water for concrete must meet ASTM C1602 requirements. Reclaimed wash water can be used within limits.
- Accessibility — Water must be available on demand. Connect tanks to the plant water system with adequate pump capacity.

Installation Considerations for Concrete Batch Plant Water Supply
Redundancy
A single tank is a single point of failure. Install at least two tanks with independent supply lines so one can be cleaned or repaired while the other maintains production. Cross-connect the tanks so either can supply the plant.
Wash Water Recycling
Concrete washout water is highly alkaline (pH 12+) and contains suspended solids. Settling it in a dedicated tank and recycling the clean water back to the process reduces water consumption by 50% or more. The settling tank needs regular cleanout as solids accumulate.
Sizing Your Tank
Tank sizing for concrete batch plant water supply depends on your usage rate, refill frequency, and peak demand. The general formula is:
Required Capacity = Daily Usage × Days Between Refills × 1.2 Safety Factor
The 1.2 safety factor accounts for peak usage days, delivery delays, and the fact that you should never run a tank completely dry (the sediment at the bottom can clog fittings and pumps). If your application has seasonal peaks, size for peak demand rather than average demand.
Maintenance Specific to Concrete Batch Plant Water Supply
Standard polyethylene tank maintenance applies: quarterly visual inspection, fitting checks, foundation verification, and vent maintenance. For concrete batch plant water supply specifically, pay extra attention to:
- Chemical compatibility: If you change chemicals or suppliers, verify the new formulation is compatible with polyethylene and within the tank's specific gravity rating before adding it to the tank.
- Residue buildup: Some liquids leave residue on tank walls over time. Annual interior inspection and cleaning prevents buildup from affecting liquid quality or reducing effective capacity.
- Fitting condition: Applications with frequent connect/disconnect cycles wear fittings faster. Replace threaded fittings at the first sign of thread damage — a cross-threaded or stripped fitting is a leak waiting to happen.
- Secondary containment: If required by your local regulations, inspect containment berms, dikes, or trays during each tank inspection. Secondary containment only works if it's intact.
Frequently Asked Questions
What size tank do I need for concrete batch plant water supply?
Start with your daily usage rate and multiply by the number of days between refills, then add 20% for safety margin. For example, if you use 50 gallons per day and refill weekly, you need: 50 × 7 × 1.2 = 420 gallons minimum. Round up to the next standard size — in this case, 500 gallons.
Do I need a chemical-rated tank or a water-only tank?
If you are storing anything other than clean water, choose a chemical-rated tank (SG 1.5 or higher). The thicker walls and higher material rating provide safety margin for chemical exposure, and you won't need to replace the tank if you switch liquids later. Water-only tanks save money but limit your future options.
What permits do I need?
Permit requirements depend on your location, the tank size, and what you are storing. Water storage typically requires no permits below 5,000 gallons. Chemical storage often requires permits, secondary containment, and fire marshal review. Agricultural exemptions may apply for farm chemical storage. Always check with your local building department and fire authority before installation.
Can I install the tank myself?
For tanks under 500 gallons, DIY installation is straightforward if you follow proper site preparation and plumbing practices. For larger tanks, we recommend professional installation — the weight involved creates safety risks, and improper placement can void the warranty. Either way, a proper foundation is non-negotiable.
How do I handle delivery and placement?
Small tanks (under 200 gallons) ship via UPS/FedEx ground. Mid-size tanks (200-1000 gallons) ship LTL on a pallet — you'll need a forklift or request liftgate delivery. Large tanks (1000+ gallons) ship via flatbed and require equipment for unloading. Call us to coordinate delivery logistics for your specific site conditions.
