How to start a service offering advice and setup for rainwater harvesting systems for homes?

The 'Water Independence' Audit and Installation Manager 💧🏡 You are selling a critical utility service: water security and lower water bills. Your value is in engineering knowledge and project management. 1. Expertise & Certification: * Technical Knowledge: Master the core principles: catchment area calculation, first-flush diverters, filtration systems (sand/gravel filters), and storage tank sizing. * Compliance: Understand the local municipal/Panchayat regulations for rainwater harvesting, as compliance is often mandatory or incentivized. 2. The Service Model (Consultancy First): * The Site Audit: Charge a fixed fee (e.g., ₹2,000 - ₹5,000) for an on-site visit to calculate the estimated rainwater yield, assess the roof, and propose a viable system (for recharging groundwater or direct use). This is a low-cost lead generation tool. * Full Implementation: For the second stage, you charge a project fee (15-20% of the total cost). You design the system, source all the materials (pipes, tanks, filters), and subcontract the physical digging and plumbing work to local, trusted contractors. 3. Target Audience: * New Construction/Developers: Pitch your service as a mandatory, value-add feature. * Independent Home Owners: Target areas facing water scarcity or high water tanker costs.
