Reject Water Storage Tank

• Zero Water Waste Solution: Collects 100% of reject water discharged from domestic RO purifiers, converting drain waste into a useful utility resource.

• Multi-Purpose Household Reuse: Safely stores reject water for cleaning utensils, mopping floors, washing cars, flushing toilets, and watering garden plants.

• Compact Next-to-RO Mount: Wall-mountable and compact design installs directly beside or below your existing RO water purifier without taking up extra space.

• Food-Grade & Leak-Proof: Built with durable, heavy-duty food-grade polymer housing featuring an automated overflow drain and leak-proof tap fittings.

Product Overview

Domestic Reverse Osmosis (RO) purifiers are essential for safe drinking water, but they typically discharge 2 to 3 liters of reject water for every single liter of purified water generated. Allowing hundreds of liters of clean, usable water to flow directly down the drain daily is both environmentally wasteful and economically impractical. While RO reject water contains a higher concentration of total dissolved solids (TDS) making it unsuitable for drinking or cooking, it remains completely clean and ideal for various non-potable household cleaning and gardening applications.

Our RO Waste Water Storage Tank is engineered specifically to capture and store this reject water right at the source. Designed to be installed adjacent to or directly beneath your domestic RO purifier, this storage container connects seamlessly to the purifier’s drain pipe. The collected water can be easily retrieved via a convenient built-in outlet tap, making it effortless to fill buckets or watering cans.

Manufactured from high-density, food-grade, non-corrosive plastic, the storage tank protects stored water from dust, insects, and atmospheric impurities. It features an integrated overflow protection port that safely redirects excess water into the standard sink drain once full. By recycling RO reject water for mopping floors, scrubbing kitchen utensils, cleaning vehicles, and nurturing household garden plants, this simple yet effective addition reduces your household's municipal water demand while supporting eco-friendly water conservation practices.

Do’s and Don’ts Advisory

Do’s

1. Use Exclusively for Non-Potable Tasks: Always reserve stored reject water for cleaning, mopping, washing utensils, and gardening.

2. Clean Tank Periodically: Drain and rinse the interior of the storage tank once every 15–20 days to remove settled mineral sediments.

3. Keep Overflow Line Clear: Ensure the top overflow tube is directed into a nearby sink or drain line to prevent accidental overflow on kitchen counters.

Don’ts

1. NEVER Use for Drinking or Cooking: Do not consume, cook, or boil this water for drinking, as it contains concentrated TDS and dissolved minerals.

2. Don't Water Delicate Hydroponics: Avoid using high-TDS reject water on sensitive indoor hydroponic plants or delicate succulents that require low-mineral water.

3. Don't Block the Overflow Outlet: Never cap or bend the overflow pipe, as backpressure can impair your RO purifier's membrane performance.

Installation Advisory & Instructions

• Positioning: Mount the storage tank on a solid wall directly adjacent to or slightly below your domestic RO water purifier for easy tubing routing.

• Connecting the Pipe: Disconnect the existing RO reject/waste water pipe from your kitchen sink drain and insert it securely into the tank’s top inlet fitting.

• Overflow Line Setup: Connect a secondary 1/4-inch tube from the tank’s top overflow port directly to your sink drain to handle excess discharge automatically.
