Imagine a world where access to clean water is a luxury. Unfortunately, that’s the reality for over 703 million people globally. For homeowners blessed with a private well, a well water storage tank becomes an essential tool for ensuring a consistent and reliable supply of clean water for their homes. (1)

Well water storage tanks act as reservoirs, storing well water and delivering it to your household plumbing system when needed. A properly installed tank not only guarantees a steady water flow rate but also protects your well pump from unnecessary cycling, extending its lifespan and saving you money on repairs down the line.

Ready to take control of your well water supply? This guide will walk you through everything you need to know about the best way to install a storage tank system. Continue reading to learn more.

Assess Your Well and Water Needs

Assess Your Well and Water NeedsAn assessment is a crucial first step. Before selecting a tank, consider these two essential factors: your well’s capacity and your household’s water usage. Finding this sweet spot guarantees your tank isn’t perpetually refilling or running dry, keeping your water pressure consistent and your well pump healthy.

An assessment will also allow you to address any issues before commencing with the tank installation. For instance, if you find that your well’s capacity is low, you can optimize water production by using high-tech well water harvesting systems from reliable manufacturers like EPP Well Solutions.

Determining Your Well Capacity

Several methods can help you determine your well’s production capacity:

Well recovery rate

This refers to how quickly your well replenishes water after pumping. If you have well documentation, it might include the well’s recovery rate in gallons per minute (GPM). The ideal recovery rate differs depending on your location. If you’re from New Hampshire, the minimum water supply capacity for households is at least 600 GPM within two hours once per day. (2)

Static water level

This is the depth to the water table within your well when the pump isn’t producing water pressure. A drop in static water level could signal a limited water source. You can measure the static water level yourself using a weighted rope and tape measure. However, static water level alone doesn’t equal well capacity.

Pumping Test

Wondering how you can accurately determine your well’s capacity? A pump test is the answer. It involves pumping water at a constant rate for a set time. A qualified well driller then monitors the water level in the well. The data allows them to accurately assess your well’s yield. This test is just optional, though.

Calculating Your Household’s Water Usage

Equally important is understanding your household’s daily water usage. Check out some water consumption estimation methods below.

Review water bills

Do you have access to past water bills? Analyze your average daily water usage based on the billing period.

Online water use calculators

Several online resources offer water use calculators. Use them to estimate your daily water consumption.

Why is it important to know your well’s capacity and your household’s water usage? That’s because it’ll guide you towards the ideal water storage options. If your chosen storage tank is too large, it might constantly cycle on and off trying to refill from a well that can’t keep up. This can lead to inefficiencies and potentially shorten the lifespan of your well pump.

On the other hand, what happens if a storage tank is too small and you have high demand? It won’t be able to provide enough water between well pump cycles. This can lead to pressure fluctuations and potentially even running out of water during peak usage times.

The sweet spot lies in selecting water storage options that allow your well to comfortably replenish the storage tank during off-peak hours. This ensures a consistent water flow throughout your home without putting undue stress on your well system.

Choosing the Right Water Storage Tank

Let’s explore the world of water tanks next! Selecting the right tank hinges on two main aspects. First is the type of tank itself. Next are the features that best suit your needs. Here are your options and the factors to consider when making a choice:
