Understanding Aquifer Protection Zones in Telangana
What is an Aquifer Zone?
An aquifer is an underground layer of water-bearing permeable rock, rock fractures, or unconsolidated materials from which groundwater can be extracted. In Telangana, the Deccan Plateau geology means most aquifers are found in fractured granite and basalt formations. Aquifer protection zones are designated areas that safeguard these vital water resources from contamination and over-exploitation, which is especially critical in a state that depends heavily on bore wells for drinking water and irrigation.
Telangana's Groundwater Landscape
Telangana sits on the Deccan Plateau, where the dominant rock types are granite, gneiss, and basalt. Unlike alluvial plains, groundwater here is stored in fractures and weathered zones within hard rock, making aquifer recharge slow and extraction unpredictable. Key groundwater concerns in Telangana include:
- Fluoride Contamination: Districts like Nalgonda, Medak, Rangareddy, and Mahabubnagar have fluoride levels exceeding safe limits (1.5 mg/L) in groundwater, causing dental and skeletal fluorosis.
- Musi River Contamination Zones: Areas along the Musi river downstream of Hyderabad (Ibrahimpatnam, Suryapet, parts of Nalgonda) have groundwater contaminated by industrial effluents and untreated sewage discharged into the river.
- Bore Well Depth Variations: In areas like Shamirpet, Medchal, and Kompally near Hyderabad, bore wells that yielded water at 100-150 feet a decade ago now require drilling to 500-800 feet due to over-extraction.
- Over-Exploited Mandals: The Central Ground Water Board (CGWB) has classified several mandals in Rangareddy, Medchal-Malkajgiri, and Sangareddy as "over-exploited" for groundwater usage.
- Granite Rock Aquifers: The fractured granite aquifers common across Telangana have limited storage capacity compared to alluvial aquifers, making them vulnerable to depletion during drought years.
Compliance and Approvals
If your property falls within an aquifer recharge area in Telangana:
- Building Permissions: All constructions must comply with HMDA/GHMC/DTCP regulations, and properties in aquifer zones may face additional environmental conditions
- Layout Approvals: New subdivisions and layouts under HMDA jurisdiction must include rainwater harvesting structures to aid aquifer recharge
- Bore Well Regulations: The Telangana Ground Water (Regulation of Drilling and Usage) Act requires permissions for new bore wells in notified areas
- Industrial Restrictions: Industries that discharge pollutants are restricted near aquifer recharge zones under TSPCB (Telangana State Pollution Control Board) norms
- Nala Conversion Land: Properties on Nala conversion land near water bodies may face additional restrictions to protect aquifer recharge pathways
- Environmental Impact: Large projects (above 20,000 sq.m. built-up area) require environmental clearance from SEIAA Telangana
Importance of Aquifer Protection
- Water Security: Hyderabad and its suburbs depend on bore wells for a significant portion of domestic water supply, especially in areas not yet connected to HMWSSB pipelines.
- Fluoride Prevention: Protecting aquifer recharge zones in Nalgonda, Medak, and Rangareddy helps dilute naturally occurring fluoride concentrations in groundwater.
- Drought Resilience: Telangana faces periodic droughts; healthy aquifers serve as a crucial backup when reservoirs like Osmansagar and Himayatsagar run low.
- Quality Assurance: Preventing contamination from the Musi river pollution, industrial zones, and agricultural runoff protects the drinking water of millions.
- Sustainable Development: With Hyderabad expanding rapidly into Shamirpet, Shankarpally, Chevella, and Maheshwaram, protecting aquifers ensures water availability for future developments.
Regulations in Aquifer Zones
Activities within aquifer protection zones in Telangana are subject to specific regulations:
- Industrial Activities: Strict controls under TSPCB on industries that may cause groundwater contamination. No red-category industries are permitted near aquifer recharge zones.
- Construction Projects: Building permits from HMDA/GHMC/DTCP may require rainwater harvesting and groundwater recharge pits as mandatory conditions.
- Agricultural Practices: Restrictions on use of pesticides and fertilizers in aquifer recharge areas, particularly in Medak and Rangareddy districts.
- Waste Management: Prohibition of waste disposal and sewage discharge that could contaminate the aquifer. GHMC mandates proper sewage treatment before disposal.
- Water Extraction: The Telangana Ground Water Act requires registration and permits for bore wells, with usage limits in over-exploited zones.

Development Regulations in Aquifer Zones
Properties within aquifer recharge areas in Telangana are subject to specific development restrictions to protect groundwater resources:
HMDA/GHMC Building Regulations in Sensitive Zones:
- Rainwater Harvesting: Mandatory for all plots above 200 sq.m. under HMDA jurisdiction. Structures must include percolation pits to aid aquifer recharge.
- Setback Requirements: Properties near water bodies (lakes, nalas, tanks) must maintain buffer zones as per GO Ms. No. 111 (FTL + 30m buffer for lakes).
- Sewage Treatment: Apartments and commercial complexes above 2,000 sq.m. must have STPs to prevent groundwater contamination.
- Bore Well Spacing: Minimum distance of 200 meters between bore wells in notified areas to prevent aquifer depletion.
Land Classification Restrictions:
| Parameter | Abadi Land (Settlement) | Agricultural / Nala Conversion Land |
|---|---|---|
| Building Permissions | Standard HMDA/GHMC norms apply | Requires Nala conversion + aquifer clearance |
| Bore Well Permits | Registration required in notified zones | Restricted; irrigation bore wells need CGWA approval |
| Industrial Use | Green/Orange category with TSPCB NOC | Not permitted in recharge zones |
| Rainwater Harvesting | Mandatory above 200 sq.m. | Mandatory for all constructions |

Frequently Asked Questions
An aquifer zone in Telangana is an underground geological formation — typically fractured granite, gneiss, or basalt in the Deccan Plateau — that stores and transmits groundwater. The Central Ground Water Board (CGWB) maps these zones across all 33 Telangana districts to regulate bore well drilling and protect groundwater resources from over-exploitation.
The CGWB classifies each mandal into four categories based on the stage of groundwater extraction: Safe (below 70%), Semi-Critical (70–90%), Critical (90–100%), and Over-Exploited (above 100%). In Telangana, over 40% of mandals in Greater Hyderabad's periphery fall under the Over-Exploited or Critical categories, meaning groundwater is being extracted faster than natural recharge.
Yes. Under the Telangana Ground Water (Regulation of Drilling and Usage) Act, bore well drilling in notified Over-Exploited and Critical mandals requires prior permission from the Telangana State Ground Water Authority. Drilling without permission in notified areas can attract penalties. Even in Safe mandals, bore well registration is mandatory.
Several mandals around Hyderabad are classified as Over-Exploited by the CGWB, including Medchal, Shamirpet, Ghatkesar, Keesara, and Uppal in Medchal-Malkajgiri district, as well as Shamsabad, Maheshwaram, and Ibrahimpatnam in Rangareddy district. Bore wells in these areas often need to be drilled to 500–800 feet depth due to declining water tables.
Properties in aquifer recharge zones under HMDA jurisdiction face additional conditions during building approval. Rainwater harvesting structures are mandatory for plots above 200 sq.m., sewage treatment plants are required for large apartments, and new bore wells must maintain a minimum 200-metre spacing. Industrial projects near recharge zones need TSPCB NOC and may be restricted to green-category industries only.
The Telangana Ground Water (Regulation of Drilling and Usage) Act empowers the state government to regulate and control the extraction of groundwater. It establishes the Telangana State Ground Water Authority, which notifies over-exploited and critical areas, mandates registration of all bore wells, and issues or denies drilling permits. Violations can lead to fines and sealing of bore wells.
Yes. HMDA and GHMC mandate rainwater harvesting for all residential plots above 200 sq.m. and all commercial buildings. In aquifer recharge zones, the requirement is stricter — percolation pits and recharge wells are mandatory for all constructions regardless of size. GHMC can deny building completion certificates if rainwater harvesting structures are not installed.
This tool uses aquifer zone boundaries mapped from CGWB and Telangana State Ground Water Department data. While it provides a reliable indication of whether a location falls within an aquifer protection zone, it should be used for preliminary assessment only. For official purposes such as building permissions or bore well permits, consult the CGWB Southern Region office or the Telangana Ground Water Department directly.
Telangana has two primary aquifer types: fractured hard-rock aquifers (granite and gneiss) covering most of the state, and basaltic aquifers (Deccan Traps) found in the northern districts like Adilabad, Nizamabad, and Karimnagar. The hard-rock aquifers have limited storage capacity and depend on fracture networks for water yield, while basaltic aquifers store water in vesicular zones between lava flows.
Groundwater quality in Telangana varies significantly by district. Nalgonda is notorious for fluoride contamination (up to 20 mg/L in some villages), while areas downstream of Hyderabad along the Musi river face heavy metal and nitrate contamination from industrial effluents. Karimnagar and Jagtial have iron-rich groundwater. Mahabubnagar and parts of Rangareddy also show elevated fluoride. The TSPCB and State Ground Water Department conduct periodic quality monitoring across all districts.
