OVERVIEW

Engineered for Reliable Water Access

HRP Infra provides full-cycle engineering services for water supply and drainage infrastructure — covering feasibility studies, hydraulic modelling, detailed design, tender documentation, and construction supervision. Our solutions are calibrated to serve both rapidly expanding urban centres and underserved rural populations.

We design pressurised distribution networks, gravity mains, overhead tanks, sumps, and drainage channels that comply with CPHEEO and BIS standards while remaining operationally efficient over decades of service life.

  • Feasibility Studies & DPR Preparation
  • Hydraulic Network Analysis (WaterGEMS / EPANET)
  • Pipeline Design (Distribution & Transmission Mains)
  • Overhead Tanks, ESRs & Ground Service Reservoirs
  • Storm Drainage & Surface Water Management
  • Construction Supervision & Project Management

WHAT WE OFFER

Our Key Service Areas

From source to tap and from rooftop to outfall, our engineering covers every node of the water and drainage cycle.

Transmission Main Design

Engineering of large-diameter trunk mains from source works to service reservoirs, including alignment optimisation, surge analysis, and material selection for GI, DI, HDPE, and MS pipes.

Distribution Network Design

Zone-based distribution systems with looped and branched configurations, pressure management zones, and demand-based nodal flow allocations for equitable service delivery.

Storage Infrastructure

Structural and hydraulic design of overhead service reservoirs (ESR/GSR), sump tanks, and balancing tanks with capacity optimisation based on population projections.

Storm Drainage Systems

Design of open drains, box culverts, storm sewers, and catch basin networks using hydrological analysis (rational method / SCS-CN) to handle peak runoff events safely.

GIS-Based Network Mapping

Asset inventory and digital network mapping using GIS and aerial survey data, enabling precise infrastructure records and informed asset management decisions.

Construction Supervision

On-site engineering supervision, quality assurance, and project progress monitoring to ensure construction is completed on schedule, within budget, and to specification.

WHY CHOOSE HRP INFRA

The HRP Advantage

Multi-Discipline Expertise

Our team combines civil, structural, mechanical, and GIS disciplines under one roof, ensuring technically coherent designs without coordination gaps.

Software-Driven Design

We use industry-standard tools including WaterGEMS, EPANET, AutoCAD Civil 3D, and GIS platforms to produce precise, simulation-validated designs.

Sustainability Focus

We integrate NRW reduction strategies, energy-efficient pumping, and climate-resilient design standards to improve long-term operational performance.

Standards Compliance

All designs adhere to CPHEEO manuals, BIS codes, and state-specific guidelines, ensuring regulatory acceptance and financing eligibility.
