2.1 Initial Assessment and Feasibility Study: Laying the Groundwork

The foundational step for any successful rainwater harvesting project is a thorough initial assessment and feasibility study. This phase determines the viability and optimal design parameters for your site.

Analyzing Rainfall Patterns in Canberra: Access historical rainfall data for Canberra, including average annual rainfall, monthly distribution, and intensity. Understanding these patterns is critical for accurately sizing collection areas and storage tanks, ensuring sufficient supply even during drier periods. Consider projected climate change impacts on future rainfall variability.
Determining Roof Area and Suitable Collection Surfaces: Conduct a precise survey of all potential collection surfaces, primarily roof areas. Evaluate roof materials for suitability (e.g., asphalt shingles, metal, tiles – some materials can leach contaminants). Identify any potential sources of pollution (e.g., overhanging trees, industrial emissions) that might impact water quality. Account for gutters, downpipes, and their current condition and capacity.
Evaluating Water Demand for Various Uses: Accurately quantify your project’s water requirements. Categorize usage into non-potable (e.g., irrigation, toilet flushing, laundry, car washing, industrial processes) and potentially potable uses (if advanced treatment is considered). Estimate daily, weekly, and peak demand volumes. For commercial projects, this involves detailed operational analysis; for residential, it considers occupant numbers and lifestyle.
Checking Local Regulations, Permits, and Building Codes: This is a critical legal and compliance step. Research specific ACT Government regulations regarding rainwater harvesting systems. This includes building codes (e.g., plumbing standards AS/NZS 3500), health guidelines (especially if considering potable use), stormwater management requirements, and any planning permits necessary for tank installation or system integration. Compliance is non-negotiable for project approval and longevity.
Site Topography and Geology: Understand the land’s contours, soil type, and existing drainage. This informs optimal tank placement (above or below ground), pump requirements, and overflow management strategies. Steep slopes might facilitate gravity feed, while certain soil types might impact foundation requirements for heavy tanks.
Economic Viability Assessment: Beyond calculating reduced water bills, a comprehensive feasibility study should include a detailed cost-benefit analysis, estimating initial capital expenditure, operational costs, maintenance, and potential savings. Calculate the payback period, net present value (NPV), and internal rate of return (IRR) to present a robust financial case for investment.

Gutters and Downpipes: Proper sizing of gutters and downpipes is paramount to efficiently capture and convey water from collection surfaces to the storage tank, especially during intense Canberra downpours. Adequate pitch and securing methods prevent blockages and structural issues. Incorporate leaf guards or gutter mesh to prevent debris entry.
First Flush Diverters: These essential devices automatically divert the initial contaminated runoff (which contains accumulated dust, leaves, bird droppings, and other pollutants from the roof surface) away from the storage tank. This significantly improves the quality of stored water, reducing the load on subsequent filtration. There are various types, from simple manual ball valves to automated systems.
Storage Tanks: This is a major decision point.
- Types: Choose between above-ground tanks (polyethylene, steel, fiberglass) or underground tanks (concrete, polyethylene). Each has aesthetic, space, and cost implications.
- Sizing: Tank capacity is crucial. It must be optimized to balance rainfall availability, projected demand, and drought periods. Oversizing can be costly, while undersizing can lead to water shortages. Expert hydrological calculations are necessary here.
- Placement and Integration: Consider structural support, foundation requirements, accessibility for maintenance, and aesthetic integration into the landscape or building design. For underground tanks, excavation and civil engineering considerations are significant.
Filtration and Treatment Systems: The level of filtration and treatment depends entirely on the intended use of the harvested water.
- Pre-tank Filtration: Basket filters, screens, and vortex filters installed before the tank remove larger debris.
- Post-tank Filtration: For non-potable uses, sediment filters (e.g., 20-5 micron) are common.
- Advanced Treatment (for Potable Use): If rainwater is intended for drinking, cooking, or bathing, it must undergo rigorous treatment. This typically includes finer sediment filtration, activated carbon filtration (for taste and odour), and UV sterilization to kill bacteria and viruses. Regular water quality testing is mandatory for potable systems to ensure compliance with Australian Drinking Water Guidelines.
Pumps and Distribution Network:
- Pump Selection: Choose appropriate pump types (submersible, surface-mounted, pressure-activated) based on tank location, desired pressure, and flow rates. Energy efficiency is a key consideration.
- Plumbing Network: Design a dedicated, separate plumbing network for harvested rainwater (often using purple pipes in Australia to signify non-potable water) to avoid cross-contamination with the mains supply. Incorporate appropriate backflow prevention devices.
