Rainwater Harvesting (RWH) Services & Turnkey Solutions

Comprehensive Guide to Rainwater Harvesting (RWH) Services & Turnkey Solutions.

With rapid urbanization, declining groundwater levels, and increasing water demand, Rainwater Harvesting (RWH) has become a crucial step toward sustainable water management. Businesses, residential communities, industries, and institutions in India are now adopting advanced RWH systems not only to conserve water but also to comply with regulatory bodies like CGWA, KGWA, and IGBC certification criteria.

In this blog, we explore the complete range of Rainwater Harvesting services, including turnkey execution, borewell recharge, rooftop harvesting, geophysical surveys, filters, water audits, and more.

Rainwater Harvesting (RWH) Services

Rainwater Harvesting Execution Services & Turnkey Projects

Turnkey RWH solutions offer end-to-end services—from planning and design to installation and commissioning.

What’s covered in a turnkey RWH project?

* Site survey & feasibility study

* Detailed design & layout

* Excavation, civil works & recharge pit construction

* Supply & installation of filtration systems

* Borewell recharge or surface storage design

* System testing & handover

* Documentation & compliance support

Benefits:

* Hassle-free installation

* Optimized design for maximum water collection

* Long-term water security

* Supports environmental certifications

Borewell Recharging

Borewell recharge is one of the most effective methods to restore groundwater levels, especially in urban zones with deep declining aquifers.

BOREWELL RECHARGE

How borewell recharge works:

* Collected rainwater is channelled through multi-stage filtration

* Clean water is directed into recharge pits

* Water percolates slowly into existing borewells

* Groundwater levels increase naturally

Advantages:

✔ Rejuvenates dry or low-yield borewells

✔ Helps maintain sustainable water table levels

✔ Reduces dependency on tanker water

Rooftop Rainwater Harvesting

Rooftop surfaces are ideal for capturing pure, contamination-free rainwater.

Typical rooftop RWH components:

* Collection gutters

* First-flush systems

* Rainwater filters

* Storage tanks or recharge pits

* Overflow management

Benefits:

* Highest efficiency due to clean surface runoff

* Suitable for homes, apartments, schools, commercial buildings

* Reduces water bills significantly

Rainwater Filters & V-Wire Screens

Filtration is the backbone of any RWH system.

Rainwater filters include:

* SS mesh filters

* Multi-grade sand filters

* Modular filters

* Self-cleaning mechanisms

V-Wire Screens

V-wire (wedge wire) screens are used in recharge wells for:

* High flow efficiency

* Sand-free percolation

* Long-term durability

These components ensure clean, safe, and efficient recharge without clogging.

Geo-Physical Survey

A geophysical survey is essential before deciding recharge points or borewell drilling.

Survey Includes:

* Electrical resistivity test

* Subsurface water detection

* Aquifer mapping

* Soil & rock formation analysis

This scientific approach ensures:

* Accurate borewell placement

* Maximum recharge efficiency

* Better long-term results

Piezo Meter & DWLR Installation

### What is a Piezo Meter?

A device used to monitor groundwater levels.

### DWLR (Digital Water Level Recorder)

A smart monitoring system used to record:

* Water depth

* Seasonal fluctuations

* Recharge rate

* Aquifer response

These tools help industries, institutions, and communities maintain compliance with CGWA guidelines

IGBC Certifications (Water Credit Compliance)

Rainwater harvesting plays a major role in IGBC Green Building Certification categories:

* Water conservation

* Sustainable site management

* Stormwater management

* Groundwater recharge

Installing a compliant RWH system helps buildings earn water credits and move closer to green certification.

CGWA & KGWA Regulations Compliance

Groundwater extraction in India is regulated by:

### CGWA – Central Ground Water Authority

### KGWA – Karnataka Ground Water Authority

Most commercial and industrial establishments must:

* Install RWH systems

* Conduct water audits

* Submit groundwater usage data

* Install piezometers & DWLR

* Ensure zero runoff discharge

Proper RWH implementation ensures legal compliance and avoids penalties.

Water Station & Rain Gauge Systems

Modern RWH setups integrate monitoring instruments.

### Rain Gauge:

* Measures real-time rainfall

* Helps calculate recharge potential

### Water Stations:

* Track groundwater levels

* Monitor water quality

* Record extraction data

These solutions provide data-driven water management for industries and institutions.

Water Audit & Water Governance

A water audit helps you understand your total water usage, wastage points, and potential savings.

### Water Audit Includes:

* Assessment of borewell yield

* Water consumption mapping

* Leakage & loss detection

* RWH integration potential

* Wastewater reuse study

### Water Governance:

* Monitoring usage

* Ensuring compliance

* Implementing conservation measures

Water audits help reduce operational costs and support sustainable water practices.
