Mastering Borehole Pump Sizing: Calculating Requirements for Optimal Performance with Nakiso Borehole Drilling

Nakiso Borehole Drilling is committed to providing efficient and reliable water solutions, and one crucial aspect of this endeavor is properly sizing borehole pumps. 

A well-sized pump ensures optimal performance, maximizes water extraction, and minimizes operational costs. In this article, we'll delve into the intricacies of borehole pump sizing, highlighting the methods and considerations necessary for achieving peak performance in your borehole system.

Understanding Borehole Pump Sizing

Borehole pump sizing is the process of selecting a pump with the appropriate capacity to meet the water demand of a particular application. At Nakiso Borehole Drilling, we understand that each borehole system is unique, with varying depths, yields, and usage requirements

Therefore, accurately sizing the pump is essential to ensure efficient water extraction and long-term reliability.

Factors to Consider

  1. Water Demand: The first step in borehole pump sizing is determining the water demand of your application. Whether it's for agricultural irrigation, industrial processes, or domestic use, understanding the daily and peak water requirements is crucial for selecting the right pump size.
  2. Borehole Yield: The yield of the borehole, measured in liters per second or gallons per minute, provides valuable information about its water production capacity. It's essential to assess the borehole yield accurately to avoid overloading or underutilizing the pump.
  3. Depth and Static Head: The depth of the borehole and the static head, which is the vertical distance between the water level in the borehole and the discharge point, significantly influence pump selection. Deeper boreholes and higher static heads require pumps with greater lifting capacities.
  4. Friction Losses: Friction losses occur as water flows through the borehole casing, pipes, and fittings. Properly calculating friction losses ensures that the selected pump can overcome resistance and deliver water at the required flow rate.

Calculating Pump Requirements

  1. Flow Rate: Based on the water demand of your application, determine the required flow rate. Consider factors such as the number of users, irrigation area, and peak usage scenarios. Select a pump that can deliver the necessary flow rate to meet these requirements.
  2. Total Dynamic Head (TDH): TDH accounts for both the static head and the dynamic head, which includes friction losses and additional head requirements. Calculate TDH using the formula: TDH = Static Head + Dynamic Head. Accurately calculating TDH ensures that the pump can lift water to the desired discharge point effectively.
  3. Selecting the Pump: Once you have determined the required flow rate and TDH, consult Nakiso Borehole Drilling's team of experts to select a pump model that matches these specifications. Consider factors such as pump efficiency, reliability, and compatibility with the borehole system.

Proper sizing of borehole pumps is essential for maximizing water extraction performance and ensuring the long-term reliability of borehole systems. By considering factors such as water demand, borehole yield, depth, static head, and friction losses, you can accurately calculate the requirements for selecting the right pump size.

Fact 1: Know Your Borehole Casings

The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)

This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.

Fact 2: Borehole Drilling Depth

The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).

Fact 3: There Is No 100% Guarantee

It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.

Fact 4: Siting Is Important
Fact 5: Know The Risks
