OVERVIEW

Engineering for Agricultural Water Security

HRP Infra provides comprehensive engineering services for dam structures, reservoir design, and irrigation scheme development. Our work covers both gravity-fed (flow) irrigation networks, which distribute water by natural slope through canal systems, and lift irrigation schemes, which pump water from rivers, reservoirs, or groundwater sources to higher-elevation command areas.

Our multi-disciplinary team manages every stage — from topographic survey and hydrological analysis through to structural design, canal network planning, tender documentation, and construction supervision — ensuring each scheme realises its full irrigation potential.

SCHEME TYPES

Flow Irrigation vs Lift Irrigation

Both types of irrigation schemes serve distinct topographic and hydrological conditions. HRP Infra designs and engineers both.

Flow (Gravity) Irrigation
Canal-based, gravity-fed water distribution

Water flows under gravity from a headworks structure (weir/barrage/dam) through a network of lined or unlined canals to the command area.

Design includes diversion weir or dam, main canal, branch canals, distributaries, minors, and field channels with proper cross-drainage works.

Canal lining design (CC, brick, HDPE) minimises seepage losses and improves conveyance efficiency for water-scarce areas.

Applicable where source elevation is above the command area — cost-effective as no energy input is required for water movement.

Lift Irrigation
Pump-driven water delivery to elevated commands

Water is pumped from a source (river, reservoir, or groundwater) to service reservoirs or distribution tanks located at higher elevations.

Design covers pump station layout, rising main selection, motor sizing, power supply infrastructure, and control systems for reliable operation.

Energy-efficient pump selection and solar-powered lift schemes are integrated where applicable to reduce operational costs and carbon footprint.

Essential for commands that cannot be served by gravity — enables irrigation of otherwise inaccessible plateau and upland agricultural areas.

WHAT WE OFFER

Our Engineering Services

Site Investigation & Feasibility

Topographic surveys, soil investigation, geo-hydrological studies, and catchment yield analysis to evaluate dam and irrigation scheme viability and optimal site selection.

Dam Design & DPR

Detailed dam design including earthen, masonry, and concrete gravity dam types — with stability analysis, seepage analysis, spillway design, and comprehensive DPR preparation.

Canal Network Design

Hydraulic design of main canals, branches, distributaries, and field channels including cross-drainage works (aqueducts, siphons, culverts) and regulation structures.

Pump Station Design

Design of pump stations for lift irrigation including hydraulic sizing, pump and motor selection, rising main design, manifold layouts, and electrical & control specifications.

Command Area Development

Field channel layout, land levelling recommendations, on-farm development works, and water allocation planning to maximise irrigated area and crop water use efficiency.

Dam Safety Assessment

Structural and hydrological safety review of existing dams per CWC Dam Safety Guidelines, including flood inundation studies, emergency action plans, and rehabilitation design.

DAM TYPES WE DESIGN

Structures Engineered for Every Site

Earthen Embankment Dams

Homogeneous and zoned earthfill dams with core, filter, and drainage design for smaller to medium reservoirs.

Masonry Dams

Stone or concrete masonry gravity dams suited to rocky foundations in medium-flow river settings.

Concrete Gravity Dams

RCC and PCC gravity dams for larger storage requirements with high stability and controlled permeability.

Diversion Weirs & Barrages

Run-of-river diversion structures to feed gravity canal systems without permanent reservoir impoundment.
