JH Consulting Engineers & Associates

About Our Partners

JH Consulting Engineers was established in 1996 by Johannes Viljoen after leaving the former KaNgwane Government as Head Engineer:  Water Provision.

We are an agricultural and Water Engineering consultancy specializing in irrigation and handling projects on a turnkey basis. This means to be involved in design, supply of material and installation of equipment.

Agricultural Engineers help feed the world by combining scientific and Engineering knowledge to find unique solutions that make our natural resources more usable while conserving and replenishing them and protecting our environment.

Irrigation System Design

By virtue of our education, training and experience, we are uniquely qualified to design the equipment, systems, and methods that continue the technological advancement in food and agribusiness.

Our focus is placed on all needs of the modern day farmers in South Africa due to the need for poverty alleviation and the role agriculture can play in this regard.  Emphasis is also placed on the needs of small-scale farmers.  The development of small-scale farmer projects are thus addressed within the Sustainable Rural Livelihoods projects.  In these projects all the necessary disciplines are integrated in specific projects to enhance meaningful and sustainable development.  An important aspect of our program is human capacity building.

  • FARM DEVELOPMENT

Design, supply and construction of infrastructure at farms , that includes bulk water supply, earth wall dams, irrigation and pump stations.  Consultation between farmer, Engineer, Economist and production Manager to determine what are the best possibilities for the Farmer as well as the Farm.

    •  POVERTY ALLEVIATION

    Design  of  vegetable gardens for communities.  We have developed and designed a unique concept in Broiler houses, specifically with the minimum cost  in mind.

    • WATER RETICULATION

    Systems to provide water to rural areas and stands.  The design, specifications, tender documents, appointment of contractors and quality control for the development of reinforced concrete reservoirs and pipelines for water provision to households.

      • RURAL PORTABLE WATER

      The design of water harvesting methods, slow sand filters, roughing filters, water purification systems, concrete reservoirs and reticulation.

        •  CIVIL WORKS

        Includes design and construction of concrete beams and slabs, design of category  1 and 2 dams, concrete bridges and waterways, pump stations and bulk water systems.

          •  IRRIGATION AND WATERWORKS

          We specialized in the  design and installation of pump houses, overhead sprinklers, drip and micro irrigation in the whole region of Southern Africa, Namibia, Swaziland and Mozambique.

          We specialized in the  design and installation of pump houses, overhead sprinklers, drip and micro irrigation in the whole region of Southern Africa, Namibia, Swaziland and Mozambique.

          We used the latest technology to optimize and analyze existing Irrigation systems. We survey the irrigation system, determine the exact pumps flow and pressures, alter the irrigation system for the most efficient  way to irrigate and therefore unable the farmer to supply  water the most effective way,  to the point of use. We also determine the water use of the crop, alter the discharge flow of the outlet nozzles, redesign the whole irrigation system and optimize the electricity use.
