Irritech was appointed by Silverlands Namibia to supply and install a bulk water transfer of 3.5km to get water from the Orange River to a booster station. A total elevation gain of 101m from the river to the highest grape block was overcome to push 3000 cubic meters an hour. Two giant barges were used to pump from the orange to the River booster station, the barges compensate for the large variation in water levels experienced on the lower parts of the orange. From the River Booster the water runs 3.5 km in three separate pipes, a 500mm, 450mm and 400mm running parallel to each other, to the in-field booster station. The in-field booster station the pumps filtered water to the grape and date blocks separately.
Seventy-three hectares of table grapes were irrigated using micro sprinklers, running laterals along the vineyard tensioning wires and hanging the sprinkler with a dropper to irrigate only the root area.
Fifty-three hectares of Medjool Dates was irrigated using adjustable arc nozzles, to keep the water away from the center of the tree while young as the center is susceptible to rotting if it gets moisture on it. Medjool dates require around 700 liters of water per day at full size.

Please be advised that after a lengthy consultative process, Ross O'Donoghue has decided to leave Irritech at the end of June this year.

His contribution to Irritech’s business during the past eleven years has been noteworthy, and he will be sorely missed by all his colleagues and clients.

He has undertaken to continue to work closely with all of our clients during this period, and will be sharing his experience, wisdom and knowledge with the Zambian team, including Jarrod Van Der Merwe who is our recent Design and Development appointment to the Zambian office, prior to his departure.

Ross’s knowledge and customer relationships will be missed, but we have a competent team who will continue to look after all your technical, sales or operational requirements in Edu Boettiger, Andre Van Wyk and Penny Van Vreden.

We also have a competent Administrative, Stores and Spares sales team to further assist you with any related matters.

Despite the recent staff changes in our Zambian office, we remain committed to serve the interests of our Zambian clients in any way possible and would ask that you please contact them for any assistance.

We look forward to your continued support, and lastly whilst perhaps premature, please join me in wishing Ross all the best in his future endeavours.

Irritech has recently assisted a student of UJ in her honours project, by sponsoring a Netafim Dripkit. These dripkits are ideal for projects such as the Emasimini one, in that they are inexpensive efficient and don't require a power source. A huge benefit is their simplicity, allowing any one to set up an irrigation scheme for themselves.

Read below what Slindile has to say about her project:

Emasimini is a change project that has been implemented by Slindile Ngubo, a University of Johannesburg Honours in Strategic Communication student. Emasimini was inspired by an assignment for an ‘Applied Strategic Communication’ module. The applied strategic Communication module required us to plan and execute a project called the change project. In terms of the project, we were tasked to create a sustainable change within ourselves, our family and community with regards to sustainability. We were tasked to have a look at the UN’s 17 sustainable goals, choose one that resonates, unpack the goal, research projects and engagements that pertain to the goal and figure out a way to change and influence others in this regard. Emasimini was established by Slindile, after the project was announced and she thought back at the time, when someone asked her ‘What don’t you care about”, at that moment she answered: “I don’t care about Farming”. With the aim of creating change within herself, and being inspird by her grandparents who were very passionate about farming, Slindile created Emasimini. In IsiZulu Emasimini is a communal garden where local farmers meet and work while sharing stories. The Emasimini Campaign falls under ‘Goal 2: Zero hunger: "End hunger, achieve food security and improved nutrition, and promote sustainable agriculture" under UN’s 17 sustainable goals. Goal 2 states that by 2030 we should end hunger and all forms of malnutrition. This would be accomplished by doubling agricultural productivity and incomes of small-scale food producers (especially women and indigenous peoples), by ensuring sustainable food production systems, and by progressively improving land and soil quality. Agriculture is the largest source of income for poor rural households. For the project, Slindile decided to partner with a group of three farmers (Ziphilise Co-op) from the rural area of Ekhobongwaneni in Pietermaritzburg KwaZulu-Natal. The purpose of this project is to double the agricultural productivity which may possibly double the incomes of these farmers, while also helping them tackle any issues that prohibit them from using their communal garden to its full capacity, and creating awareness of the project so that it can grow and venture into more rural communities in the Pietermaritzburg area.
Objectives and Evaluation of Emasimini for Ziphilise Garde:
Objective 1:
To introduce a water irrigation system that is sustainable.
A water tank was installed in the garden. A water vehicle is to fill the tank every week to keep it full. A drip kit irrigation system was installed to make watering of plants easier.

Objective 2:
To double the agricultural productivity of the Ziphilise Garden.
120 seedlings were planted, and 6,12kgs worth of seeds are still to be planted.
Objective 3:
To raise awareness of the Emasimini Campaign by at least 10%
