RO Waste Water Storage Tank

by

Reverse Osmosis (RO) systems are essential for providing clean drinking water, but they generate significant wastewater. An RO waste water storage tank offers a practical solution to manage this byproduct effectively. Instead of letting wastewater go down the drain, storing it in a dedicated tank allows you to repurpose it for household chores, gardening, or other non-potable uses. This guide explores how to choose, install, and maintain an RO waste water storage tank while maximizing water conservation.

What is an RO Waste Water Storage Tank?

An RO waste water storage tank is a container designed to collect and store the rejected water from your RO system. Typically, RO systems produce 3-4 liters of wastewater for every liter of purified water. This tank helps you:

  • Reduce water wastage by repurposing wastewater.

  • Lower utility bills by reusing water for cleaning or irrigation.

  • Minimize environmental impact by preventing unnecessary drainage.

Benefits of Using an RO Waste Water Storage Tank

1. Water Conservation

Storing RO wastewater prevents it from being wasted. A single household can save 200-300 liters/month by reusing this water.

2. Cost Savings

Reusing stored water for mopping, car washing, or gardening reduces dependency on municipal supply, cutting water bills.

3. Eco-Friendly Solution

Repurposing wastewater aligns with sustainable living goals and reduces strain on local water resources.

4. Easy Integration

Most RO waste water storage tanks are compact and can be installed under sinks or outdoors without hassle.

How to Choose the Right RO Waste Water Storage Tank

1. Tank Capacity

  • Small households (1-3 members): 20-30 liters.

  • Larger families (4+ members): 50-100 liters.

2. Material

  • Plastic (PVC): Lightweight, affordable, and corrosion-resistant.

  • Stainless Steel: Durable and ideal for outdoor use.

3. Compatibility

Ensure the tank fits your RO system’s outlet size and pressure requirements.

4. Brand & Warranty

Opt for reputed brands like Kent, Aquaguard, or Livpure for reliability and after-sales support.

Installing an RO Waste Water Storage Tank: Step-by-Step

1. Position the Tank

Place the tank near your RO system, preferably under the sink or in a utility area.

2. Connect to the RO Outlet

Attach the tank’s inlet pipe to the RO system’s wastewater outlet using a PVC connector.

3. Add a Pump (Optional)

For overhead tanks or long-distance water transfer, install a small pump to boost pressure.

4. Test for Leaks

Run the RO system and check connections for leaks. Tighten fittings if needed.

Maintenance Tips for RO Waste Water Storage Tanks

1. Regular Cleaning

  • Drain and scrub the tank monthly to prevent algae or sludge buildup.

  • Use a mix of vinegar and water for natural cleaning.

2. Inspect for Damage

Check cracks, leaks, or UV degradation (for outdoor tanks) every 3-6 months.

3. Replace Filters

If your tank has a pre-filter, replace it annually to maintain water flow.

4. Monitor Water Quality

Avoid using wastewater with high TDS (>1,500 ppm) for plants, as it may harm soil.

Creative Ways to Reuse RO Waste Water

1. Household Cleaning

  • Mopping floors.

  • Washing utensils or cars.

2. Gardening

  • Water plants (if TDS is low).

  • Clean garden tools.

3. Toilet Flushing

Redirect stored water to flush toilets, reducing freshwater use.

4. Construction Use

Mix wastewater with cement for small DIY projects.
