RAIN WATER HARVESTING
SOLUTIONS
Harvest Nature. Live. Live Sustainably
Rainwater harvesting by Steel Castles is a smart, sustainable solution for container home owners who want to reduce their water bills, increase self-sufficiency, and support the environment. By collecting and storing rainwater from your roof, you can use this natural resource for irrigation, laundry, toilets, and even potable water with proper treatment. Our advanced rainwater harvesting systems are designed for easy installation and minimal maintenance—perfect for modern container living
HOW OUR 4-STEP
SELF-CLEANING RAIN WATER SYSTEM WORKS
-
1. Collection:
Rainwater is captured from your container home’s rooftop, using gutters and down pipes to direct water into the system.
-
2.Self-Cleaning Pre-Filter (3-in-1):
The rainwater first passes through a maintenance-free prefilter that removes leaves and debris, ensuring only clean water enters your tank. This filter uses proven basketless technology for continuous filtration and includes an aerator for improved waterquality12.
-
3. Aerator & Calming Inlet:
Filtered water flows into the storage tank via a stainless steel aerator and calming inlet. This process adds oxygen and reduces the velocity of incoming water, preventing sediment from stirring up inside the tank12. -
4. Floating Intake
When you use the stored water, it is drawn from just below the water surface—the cleanest layer—using a stainless steel floatingintakedevice12. -
5.Backwater Valve & Overflow Protection:
When the tank is full, excess rainwater is safely directed away through a backwater valve and vermin guard, protecting your home and the environment
