Our expert team designs custom rooftop rainwater harvesting systems that collect, filter, store, and recharge rainwater safely. We help apartments, factories, offices, schools, hospitals, and commercial buildings reduce water dependency and support sustainable water management.
Whether you need rainwater harvesting for apartments or an industrial rainwater harvesting system, we deliver complete end-to-end solutions with high-quality installation and long-term performance.
Our rooftop rainwater harvesting systems are designed for efficient rainwater harvesting for commercial buildings, collecting rainwater from rooftops through durable gutters and pipelines. The system safely directs water to filtration units, storage tanks, or recharge pits.
Benefits include:
We provide rooftop rainwater harvesting solutions for:
Our filtration systems remove dirt, leaves, and suspended particles, making them ideal for rainwater harvesting for apartments.
We install:
These systems help improve groundwater levels and support long-term water availability. Harvested rainwater can be treated through advanced water treatment plants for various industrial and utility applications.
We design underground and overhead storage systems to collect harvested rainwater for reuse.
Stored rainwater works well for:
Rainwater harvesting for commercial buildings and apartments helps reduce freshwater consumption and supports sustainable water management. When combined with water recycling systems, it maximizes water savings. Industries can also explore our Effluent Treatment Plants (ETP) & ZLD Systems for efficient wastewater treatment and reuse.
A rain water harvesting system collects rainwater from a rooftop, filters it, and stores or recharges it for future use through five stages:
This five-stage design applies at any scale — from rainwater harvesting for apartments with limited terrace space to a large-scale industrial rainwater harvesting system spread across multiple rooftops and yards. The core components (gutters, conduits, filters, storage tanks, recharge pits) stay the same; only the sizing and pipe network change based on site conditions.
At ERAHBT, every rain water harvesting system we design follows this collect-store-recharge framework, customized to your rooftop area, rainfall pattern, and water demand.
Water scarcity continues to grow in cities and industrial areas. A professionally designed rain water harvesting system helps you manage water more efficiently. Rainwater harvesting captures rainwater before it flows into drains, storing or recharging it for future use. Want to estimate your site’s water-saving potential?

Rainwater harvesting captures rainwater before it flows into drains. The system stores or recharges water underground for future use.
Our team studies:
Based on these factors, we create the right rainwater harvesting solution for commercial buildings and residential properties. For expert insights on system planning and regulatory requirements, explore our Rainwater Harvesting for Commercial Buildings: Design and Compliance Guide.
Rainwater harvesting offers environmental and economic advantages by conserving water resources and reducing pressure on groundwater supplies.
A professionally installed rain water harvesting system offers long-term environmental and financial benefits.
Recharge pits and wells improve underground water levels and support aquifer sustainability.
Stored rainwater reduces dependence on municipal and tanker water supply.
The system controls runoff water and helps reduce flooding risks.
Rainwater becomes a reliable additional water source for daily non-drinking applications
Rainwater harvesting supports green building goals and sustainable development.
Our process includes:
We ensure every rain water harvesting system and industrial rainwater harvesting system delivers maximum performance, long-term efficiency, and compliance with applicable local water conservation regulations. For a complete water management solution, explore our Water Recycling Systems, Sewage Treatment Plants (STP), and Effluent Treatment Plants (ETP & ZLD Systems).
Looking for a trusted rain water harvesting system company for your apartment, commercial building, or industrial project? Our team delivers reliable, cost-effective, and sustainable water management solutions.
A rain water harvesting system collects rainwater from rooftops through gutters and pipelines. The water is filtered and then stored in tanks or directed to recharge pits, borewells, or underground aquifers for future use. This helps reduce freshwater consumption and supports sustainable water management.
Yes. Rooftop rainwater harvesting is an effective solution for homes and rainwater harvesting for apartments. It captures rainwater from the building roof, helping reduce water bills, improve groundwater levels, and provide an additional water source for non-potable applications.
Rainwater harvesting for commercial buildings helps reduce dependence on municipal water, lowers operating costs, supports sustainability goals, and assists in meeting local environmental regulations. It is ideal for offices, malls, hotels, hospitals, schools, and commercial complexes.
An industrial rainwater harvesting system enables factories and manufacturing units to capture and reuse rainwater for process water, cooling systems, landscaping, and groundwater recharge. It helps reduce freshwater consumption, supports ESG initiatives, and improves long-term water security.
The ideal rain water harvesting system depends on factors such as rooftop area, annual rainfall, water demand, soil conditions, and available space for storage or recharge. A professional site assessment ensures the system is designed for maximum water recovery and long-term performance.
Many municipalities and urban development authorities in Maharashtra encourage or mandate rain water harvesting systems for certain residential, commercial, and industrial developments as part of water conservation and sustainable building regulations. Requirements may vary based on local authority guidelines.
Government incentives and subsidy programs for rain water harvesting systems may be available through state departments, municipal corporations, or local authorities, depending on the location and project type. It is advisable to check the latest schemes applicable in your area.
ERA Hydro-Biotech designs and installs rain water harvesting systems for residential, commercial, and industrial projects. Our expertise in site surveys, customized system design, quality installation, and ongoing maintenance ensures long-term performance.
Yes. Combining a rain water harvesting system with water recycling solutions creates a comprehensive water management strategy. Rainwater can be used alongside treated wastewater for flushing, landscaping, cooling, and other non-potable applications, maximizing water conservation.
The amount of water collected through rooftop rainwater harvesting depends on the roof area, local rainfall, and system efficiency. Larger rooftops and higher rainfall typically result in greater water collection, making the system a valuable long-term investment for water conservation.
