I am currently in the process of constructing a new house and I am seeking assistance in designing a charged rainwater harvesting system from scratch. I believe that this forum is home to knowledgeable individuals who can provide valuable insights and expertise in this area.
To provide you with relevant information, I have attached building drawings that illustrate the size of the house, roof structure, and the positions of the downpipes.
In addition, I have an existing 140,000-litre water tank located approximately 10 meters away from the house on the southwest side.
The water tank is an above-ground Pioneer tank but due to the land topography it access point sits 500mm above slab height and 2.1m below gutter height, with water access available through the top of the tank, which is closest to the house.
The harvested water will be filtrated through Puretec system so that the house can be solely dependant on water captured and only flicking to scheme water when required to, in a return pipe to the house at veranda two
The roof gutters will be covered by a gutter guard system which will be at its smallest form of aperture 2mm to restrict debris but not water flow. The gutters are half round 105 gutters and lead to downpipes at this moment I am not sure of the downpipe size but might be 90mm.
I am not fully sure how the water will indeed rise up into the water tank so will need some assistance in this understanding also.
I would like the rainwater harvesting system to be designed with the following features:
- Purge valve: Incorporating a purge valve to allow for the removal of sediment and debris that may accumulate in the system over time.
- First flush system: Implementing a first flush system to divert and discard the initial runoff from the roof, which often contains contaminants and debris.
As I plan to undertake the installation myself, I am specifically seeking guidance on the following aspects:
- Pipe selection: Recommending the appropriate types of pipes to be used in the system, considering factors such as durability, compatibility with rainwater, and ease of installation.
- Pipe sizing: Determining the optimal pipe size based on the anticipated flow rate and distance between various components, including the downpipes, tank, and points of use within the house.
- Pipe positioning: Providing insights on the most efficient and practical positioning of the pipes, considering factors such as gravity flow, accessibility for maintenance, and aesthetic considerations.
We live in Perth WA.
I greatly appreciate any assistance, suggestions, or resources that you can provide to help me design an efficient and effective charged rainwater harvesting system. Please feel free to request any additional information or clarification if needed.
Thank you all in advance for your support and valuable contributions!
