Enhance Your Solus Decor Dome Water Feature with an Eco-Friendly Rainwater Collection System

Rainwater harvesting is an environmentally friendly and efficient way to make the most of natural resources. At Solus Decor, we recommend integrating this system with your Solus Decor Water Feature to enhance both its functionality and sustainability. Here’s a step-by-step guide to help you build a rainwater collection system for your garden.

Understanding the Basics

Before you begin, it’s important to understand the primary components of a rainwater collection system:

Catchment Area:
Typically, this is your roof, where rainwater is collected.

Gutters and Downspouts:
These channel the water from the roof to a collection point.

Filtration System:
Ensures the collected water is free from debris and contaminants.

Storage Tank:
Where the filtered water is stored.

Distribution System:
Channels water from the storage tank to your water feature.

Selecting the Right Components

Catchment Area and Gutters
Ensure your roof is suitable for rainwater harvesting. The surface should be clean and free from pollutants. Install gutters and downspouts made from non-toxic materials to channel the water effectively.

Filtration System
Choose a reliable filtration system. Basic options include leaf guards and mesh screens, but for cleaner water, consider a first flush diverter, which discards the initial runoff that may contain contaminants.

Storage Tank
Your storage tank can range from simple barrels to larger, more sophisticated tanks. Ensure the tank is food-grade and UV-resistant. Calculate the required tank size based on your local rainfall data and the roof area.

Distribution System
A pump might be necessary to move water from the storage tank to the water feature. Ensure the pump is compatible with the water feature’s requirements.

Installation Steps

Step 1: Prepare the Site Choose a location for your storage tank that is stable and near the downspouts. If your water feature is far from the tank, consider trenching for underground pipes.

Step 2: Install Gutters and Downspouts Install gutters along the edges of your roof, leading to downspouts. Ensure they are securely fastened and sloped correctly for efficient water flow.

Step 3: Set Up the Filtration System Attach the leaf guards or mesh screens to the gutters. Install the first flush diverter on the downspout to ensure cleaner water enters the tank.

Step 4: Install the Storage Tank Place the tank on a level surface. Connect the downspout to the tank’s inlet. Ensure there is an overflow outlet to handle excess water during heavy rains.

Step 5: Connect the Pump and Distribution System Install the pump, such as the Tuthill FHRP32V, as per the manufacturer’s instructions. Connect it to the tank and the water feature using suitable piping. If necessary, install a pressure regulator to maintain a consistent water flow.

Self-Contained System Benefits

One of the standout features of Solus Decor water feature are their self-contained design. This means the water feature does not require a continuous connection to a mains water supply. The system recirculates the water it uses, making it ideal for integration with a rainwater harvesting system. Here are some benefits:

  • Water Conservation: By using harvested rainwater, you reduce your dependency on the municipal water supply.
  • Eco-Friendly: Harvesting rainwater reduces stormwater runoff and erosion, contributing positively to the environment.
  • Cost-Effective: Once set up, the rainwater collection system minimizes water bills and maintenance costs associated with water supply.

Encouraging people to use a rainwater collection system instead of relying on a water supply ensures sustainability. It promotes an eco-friendly approach by reducing water consumption and the overall carbon footprint.

Maintenance Tips

Regular maintenance is crucial to ensure the longevity and efficiency of your rainwater collection system.

  • Inspect and Clean Gutters and Downspouts: Check for clogs and remove debris regularly.
  • Monitor the Filtration System: Clean or replace filters as needed.
  • Check the Storage Tank: Inspect for leaks and clean the tank periodically.
  • Maintain the Pump: Follow the manufacturer’s maintenance schedule for the pump.

Enhancing Efficiency

To maximize the efficiency of your rainwater collection system, consider the following tips:

  • Rainwater Harvesting Calculator: Use online tools to estimate potential water collection based on your roof size and local rainfall data.
  • Water Usage Planning: Plan how much water your Solus Decor Water Feature requires and adjust your storage and usage accordingly. For example, the 36″ Dome Water Feature will require approximately 15-30 litres of water.
  • Advanced Filtration: If you plan to use the water for purposes beyond your  water feature, such as gardening, consider additional filtration like carbon filters or UV sterilizers.
