CGWA Guidelines

By Vishal Borewell Drilling Service
The Central Ground Water Authority (CGWA) under the Ministry of Jal Shakti has issued comprehensive guidelines for regulating groundwater extraction and promoting sustainable practices like rainwater harvesting and piezometer installation. Here's a breakdown tailored to your interests in borewell services and community education:
---

🛠️ CGWA Guidelines Overview

1. Piezometer Installation
- Mandatory for industries and infrastructure projects extracting groundwater.
- Must be installed to monitor groundwater levels and quality.
- Data from piezometers should be recorded monthly and submitted to CGWA.
- Specifications include:
  - Minimum depth: same as the borewell.
  - Proper casing and locking to prevent contamination.
  - GPS-tagged location and unique identification.

2. Borewell Regulation
- No Objection Certificate (NOC) is required from CGWA before drilling or using borewells in notified areas.
- Borewell construction must follow approved technical standards.
- Illegal or unregistered borewells are subject to sealing and penalties.
- Water meters and flow meters must be installed to monitor usage.

3. Rainwater Harvesting
- Mandatory for all buildings (residential, commercial, industrial) above a certain plot size.
- Rooftop rainwater harvesting systems should be designed to:
  - Recharge groundwater through percolation pits or recharge wells.
  - Prevent runoff and water wastage.
- CGWA provides standard designs and manuals for implementation.
- Annual maintenance and desilting of recharge structures is required.

Borewell drilling is a common practice used to access groundwater for various purposes such as irrigation, industrial use, and domestic water supply. The process involves drilling a hole into the ground to reach an aquifer and extracting water through a pump. The cost of borewell drilling can vary based on several factors, including the type of soil, depth of the borewell, equipment used, and location. One important aspect to consider when determining the cost of borewell drilling is the per feet rate charged by drilling contractors. Per-Feet Rate for Borewell Drilling: The per-feet rate for borewell drilling can vary significantly depending on various factors. On average, the per-feet rate for borewell drilling in India ranges from ₹100 to ₹300 per foot. However, this rate can be higher or lower based on the following factors: 1. Type of Soil: The hardness and composition of the soil can impact the drilling rate. Hard rock formations require specialized equipment and more labor, which...

Explore the challenges you may encounter with a borewell and master the strategies for addressing them with our detailed guide on borewell issues and their solutions. Borewells serve as a crucial water source for numerous households, farms, and businesses. By utilizing borewell drilling methods, they access subterranean water sources, offering a consistent supply of water. However, borewells can face various issues that hinder their efficiency and water output. In our detailed guide, we'll delve into the typical problems borewells may face and propose effective solutions to ensure a continuous water supply. Understanding Borewells What Is a Borewell? A borewell is a deep, narrow shaft bored into the earth to reach underground water supplies. It generally includes a casing pipe to prevent the well's collapse and a submersible pump to draw water upwards. The depth of a borewell varies based on its geographic location and the required water quantity. The Role of Borewe...
