Near the coast, fresh groundwater floats on denser seawater. Pump too hard and the saltwater front moves inland, often for good. For a coastal industrial SEZ in Andhra Pradesh we delivered a suite of five linked studies: water quality and intrusion, aquifer performance, ERT geophysics, a flow model and a density-driven salt transport model. The same approach works for ports, SEZs, refineries, desalination intakes and coastal towns.
What you get
- TDS and chloride maps, Piper diagrams and water-type classification
- Pumping tests for aquifer properties and safe yield
- ERT surveys to map the fresh–saline interface
- Density-driven flow and salt transport models (SEAWAT)
- Pumping limits for each well field and scenario
- Monitoring network to catch intrusion early
Who it is for
SEZs and industrial parks on the coast, ports, power plants, refineries, salt and chemical works, resorts and coastal municipalities.

Common questions
Can saline groundwater be used instead?
Yes. Under the CGWA guidelines, industries drawing saline groundwater are exempt from abstraction charges, provided effluent disposal protects water bodies and aquifers. We assess whether saline water suits your process.
How far ahead does the model look?
Usually 10 years or more, under the planned pumping and higher-demand scenarios.
