One of the most critical decisions you have to make when setting up an irrigation scheme is the one on the type of water pumping machines you will be using. There are, of course, certain irrigation schemes where the nature of things is such that the power of gravity can be leveraged upon to draw the water from the source and deliver it to the fields being irrigated. But in most cases, the water has to be pumped: because in most cases, the source of water to be used in irrigation tends to be at a lower level than the fields being irrigated.
While selecting the water pumping machines for use in an irrigation scheme, you need to look at the machines’ pumping capacities. You need to select a machine that has capacity to deliver the water you currently need for irrigation. Ideally, you should actually go for a machine with extra capacity: one that can cater for your immediate future needs (as your irrigation project expands).
Another important consideration to be made while selecting the water pumping machines for use in an irrigation scheme is the one as to the ease with which the machines can be maintained. You need to ask yourself how easy it will be for you to find spare parts — and people with the expertise — to repair the machine when it breaks down. Some of the newer irrigation systems are patented, and this has cost implications.
Yet another important consideration to be made while selecting the water pumping machines for use in an irrigation scheme is the one as to the cost of keeping the machines running. An important consideration here is at to how the machines are powered: are they, for instance, diesel-powered? Or are the machines powered by electricity? These are important considerations. Failure to take this factor into consideration while selecting a water pumping machine is akin to ignoring credit card interest rates while trying to select a credit card to apply for. That decision, to ignore the credit card interest rates while selecting a credit card to apply for, is likely to come to haunt you a great deal in the future. It is the same with water pumping machines: if, for instance, you opt for one that is exclusively powered by electricity, and you happen to be operating in an area where electricity supply is not very reliable, you are likely to regret that decision a great deal later on.
