About us

Northern Stock Water specialises in water development and irrigation products for farms, cattle stations and mines.

Elsam Plastics is our Australian Standards-certified brand of metric (from 25mm to 110mm) and rural polyethylene pipe (PE/poly pipe) products. We continuously audit our poly pipe products to ensure they meet the highest criteria.

Based in Katherine NT, we supply and service clients throughout the Northern Territory, Queensland and the Kimberley region in Western Australia.

Company background

Northern Stock Water was the first company in the Northern Territory to produce concrete cattle troughs. In order to supply a complete product range to our customers, we then started selling the parts needed to fit the troughs, such as poly and steel fittings, PE compression fittings and float valves.

To meet a market demand for locally produced polyethylene pipes, we imported a PE pipe manufacturing machine from Germany and started producing quality poly pipes in our NT factory. Over the past few years alone, we have manufactured thousands of kilometres of poly pipe for customers across the Northern Territory, the Kimberley and Queensland.

While initially most of our clients were large cattle farms, our current client base includes agriculture and horticulture businesses as well as the mining industry.

Our product range now runs in the thousands, which means you should be able to find any water supply and irrigation product, part and accessory you need to set up a complete irrigation system on your farming or mining land. The most recent addition to our product line is a steel liner water tank, produced by us.

Our staff & expertise

With increasing numbers of clients to please and orders to fill, Northern Stock Water is an ever-growing business. We currently employ 20+ dedicated staff, including 4 highly qualified Production Engineers who each have at least 10 years’ experience in the industry. The team is led by company owner Adrian Brown, who started the company after years of hands-on experience in developing water systems on cattle stations.

With our in-depth engineering knowledge of water flow, combined with our satellite mapping services, we can design a water system that is the most effective for your particular piece of land – whatever the size and topography.

Proper installation is key to having an efficient water system. If poly pipes aren’t installed deeply enough in the ground, they’re at risk from bush fires. We have our own bulldozer and all the skills, knowledge and parts needed to ensure your PE pipes are properly fitted so your water system will give you long-lasting performance.

For a full range of quality pipes, tanks and fittings for your farm or mine and engineering services you can rely on, Northern Stock Water and Elsam Plastics can meet your every need.


As a successful and growing business, Northern Stock Water regularly has employment opportunities available for a range of positions.

New positions available will be posted on this page. However, if you are interested in working for us and no jobs are currently advertised, please feel free to contact us with a general enquiry.
