What kind of wells are there

The well that you choose will determine the water quality and quantity that you receive. It will also affect the maintenance process that you will require. Dug wells are shallow and they are not the best option for your drinking water. This type of well poses the highest risk of contamination of the water supply due to poor protection from surface water.

A dug well usually consists of a large diameter hole that is usually over 2 feet wide, and it can be constructed by hand or using excavation equipment. The large-diameter wells are usually constructed using corrugated galvanized steel or prefabricated concrete tile. Older wells are often constructed of stone, brick, or wood cribbing and they are very susceptible to surface-water seepage.

Bored wells are constructed using a boring machine and they usually have an average depth of about 15 m or 50 ft. The wells that are usually about 2 feet in diameter are constructed using an earth auger and concrete is the most common material used. With much better options available, dug wells are not recommended. In light of construction processes, bored wells can extend much deeper under the water table than hand-dug versions. Both bored and dug wells have a large diameter, exposing a lot of water to the aquifer.

These well types can obtain water from less-permeable materials like silt, clay, and fine sand. Due to their shallow nature and lack of continuous grouting and casing, these well types are subject to contamination from surface sources, giving them a disadvantage. If you have an existing well water system that needs updating, replacement, or service, we can help.

If you are building a brand-new home, we can assist with selecting and building the perfect new well system. The following is an overview of these three important well types: 1. Drilled Wells Drilled wells are the most common well water systems CT uses. Driven Wells Driven wells are the simplest and most basic well pump CT residents use. Geologic Survey, Groundwater Wells Below are descriptions of the basic components found in a private water well.

The Water Systems Council had a more detailed well component diagram and other well-owner education materials. Well component descriptions adapted from the National Ground Water Association Proper well location and construction are key to the safety of your well water. The well should be located so rainwater flows away from it. If this water pools near your well, it can seep into it and potentially cause health problems. Appropriate well construction depends on local geologic and groundwater conditions.
