Service & Repair of Water Wells
Since more than 97% of our freshwater is underground and less than 3% exists on the earth’s surface in lakes, streams and reservoirs, it is easy to see how abundant groundwater is compared to surface water and how important it is to protect this valuable resource.
Drilled wells can protect the generally greater purity of underground water more easily and more securely than dug wells do. Merrill Water Systems is proud to have been both a provider and protector of our vast groundwater resources for many years and we look forward to continuing in this important role for years to come.

Service & Repair of Water Well Pumping Systems
Our service crews are expert in all phases of installation and repair for residential, commercial and municipal pump systems. You can rely on Merrill Drilling & Pump Service for prompt, courteous attention to your water system needs – for regularly scheduled installations or “no water” emergencies.
We have featured top-of-the-line products such as Grundfos pumps and Amtrol tanks and we can supply and name brand to meet your specific requirements.
Once a well is drilled, the next crucial step is to “size” the pump system for the water needs of the project. This means ensuring that the entire system is calculated to deliver the optimum amount of water at the best pressure possible.
A typical pump system for a single family home includes a submersible pump installed in the well with a drop pipe, motor cable, and torque arrestors; well cap, pitless adapter, water line, UF cable and assorted fittings from the well to the house; and a hydropneumatic pressure tank with controls (pressure gauge, pressure switch, check valve, pressure relief valve, and boiler drain) set up in the basement and connected to the well.
Some water systems are designed to store water during times of low demand (such as night time). This stored water can be used later to supply water during peak demand (laundry, lawn watering). We can plan a water system based on your needs and water source.
In contrast to a domestic well, irrigation wells must be able to produce water at steady high rates for extended periods of time. Irrigation systems must be carefully designed to minimize pumping costs and to prevent excessive drawdown of the well.
