Overview

Elevated Storage That Keeps Water Flowing

An Overhead Water Tank (OHT) is the final elevated storage point in any municipal water supply system — storing treated water at height to maintain adequate pressure throughout the distribution network, ensuring reliable supply to every household and institution it serves.

IngrOInfo has engineered a targeted offering of quality beyond expectation in OHT construction. Through collaborations with foremost talents in the field, the usage of the finest materials and cutting-edge construction technologies, and impeccable project execution — IngrOInfo delivers overhead tank structures that serve communities reliably for decades.

We undertake OHT construction for municipal corporations, urban local bodies, panchayats, gram panchayats, state water boards, and government housing schemes — executing structures from design through civil construction, staging, plumbing connections, testing, and handover.

OHT Construction & Rehabilitation

Over Head Water Tank (OHT) Construction

End-to-end construction of elevated water storage structures for municipal and government water supply schemes.

  • Site survey, soil investigation, and structural design as per IS codes
  • Foundation construction — isolated, combined, or raft as per soil conditions
  • RCC staging construction — columns, beams, bracings, and staircase
  • Tank structure construction — container, roof dome, and floor slab
  • Inlet, outlet, overflow, washout, and scour valve connections
  • Internal and external waterproofing treatment
  • Anti-corrosion painting and surface finishing
  • Hydraulic testing, commissioning, and handover documentation

OHT Repair, Rehabilitation & Capacity Expansion

Structural repair, waterproofing restoration, and capacity enhancement of existing overhead water tanks.

  • Structural condition assessment and load-bearing analysis of existing OHTs
  • Crack repair, spalling treatment, and concrete restoration
  • Re-waterproofing of tank interior and exterior surfaces
  • Staging column jacketing and structural strengthening
  • Replacement of inlet, outlet, and overflow valves and pipework
  • Anti-corrosion treatment and re-painting of steel components
  • Capacity enhancement by raising tank wall height where structurally feasible
  • Post-rehabilitation hydraulic testing and certification
Types of OHT Structures

OHT Configurations We Build

We design and construct overhead and ground-level water storage structures across all standard configurations used in Indian municipal water supply systems.

ELSR

Elevated Service Reservoir

Multi-column RCC staging with container at height. Most common OHT type for urban municipal supply — capacities from 50 KL to 5 ML and beyond.

GLSR

Ground Level Service Reservoir

RCC or brick masonry ground-level storage tanks fed by pumps. Used as balancing reservoirs in distribution systems and water treatment plant storage.

Intze Type

Intze Tank (Circular)

Traditional conical-bottom circular RCC tank on multi-column staging. Efficient structural form for large-capacity elevated storage in municipal systems.

Rectangular

Rectangular OHT

Rectangular RCC container on staging — used where construction space is constrained or where the tank serves a linear distribution zone.

Mini OHT

Mini Elevated Storage Tank

Smaller-capacity elevated tanks (5 KL to 50 KL) for rural habitations, gram panchayats, and last-mile supply under Jal Jeevan Mission.

Pressed Steel

Pressed Steel Sectional Tanks

Prefabricated pressed steel panel tanks on RCC or steel staging — rapidly deployable for emergency water supply or temporary storage requirements.

Key Features

Built for Decades of Reliable Service

Every OHT we construct is engineered for structural integrity, water quality protection, and long-term operational reliability — meeting all applicable IS codes and government scheme specifications.

IS Code Structural Design

All OHT structures are designed per IS:3370, IS:456, IS:875, and IS:1893 — accounting for seismic zone, wind loads, water pressure, and soil bearing capacity.

Waterproofing & Water Quality

Internal waterproofing treatment using approved materials — ensuring zero leakage and protecting water quality from contamination at the storage stage.

🏗️

Turnkey Project Execution

From site survey and structural design through foundation, staging, tank construction, plumbing connections, testing, and handover — all under a single contract.

Level Sensor & SCADA Integration

OHTs can be fitted with level sensors and integrated with SCADA systems for real-time water level monitoring and automated pump control from the control centre.

Scheme-Aligned Construction

OHT construction aligned with JJM, AMRUT 2.0, and Smart Cities Mission technical specifications — with documentation ready for government audit and scheme billing.

Hydraulic Testing & Certification

All tanks are hydraulic-load tested before commissioning — with water-tightness certification and structural safety clearance at handover.
