Maryland Well Yields

A well yield is a measurement of how much water, how fast and for how long your well can produce. Measured in gallons per minute, a well yield is one of the major indicators of your well’s performance. Well yield testing is required when you drill a new well or sell a property that has a well. In Maryland, a residential well has to produce a minimum yield of one gallon per minute in order to meet the well standards.

R & G Water Systems is a Maryland well yield expert that can perform an accurate well yield test according to the state regulations on any new or existing wells. We can also test the water quality and the flow rate to make sure your well is suitable to sustain your household’s water usage. For the purpose of property transfer, well yield test results are good for three years and water quality analysis is valid for 180 days in Maryland.  R & G Water Systems, Inc. provides expert well yield tests and consultation in Central Maryland including  Westminster, Columbia, Ellicott City, Carroll County, Howard County, and Baltimore County

What if My Well Yield is Not Sufficient?

Different types of wells may require different yields depending on the specific well construction and technologies. If the test results show that your water well doesn’t produce enough water or can’t sustain a consistent flow, you have a few options other than re-drilling. One of them is to add additional or intermediate storage that would satisfy the water demand during peak hours. The second option is to install a secondary well connected to your primary well, so that both of them yield at least 0.5 gallons per minute. You can also minimize household water use or invest in water-saving appliances to reduce the stress on your well. R & G Water Systems can help you figure out the best solution to your low-yield well.

What Our Customers Say...

  • This family-owned business was very responsive; they consulted over the phone and they recommended only replacing a faulty valve rather than selling me an entirely new sump pump unit that I didn’t need.

  • R & G was excellent. Came out on the weekend and did not charge any uprate. The work was great, the service was fantastic, and he was always available for follow-up calls and questions. Highly recommended.

  • R & G was great to work with – they responded quickly and we discussed various options over the phone throughout the weekend. They performed the work when they said they would for the price they quoted. Very satisfied.

  • Honesty goes a long way in my book. Rick was extremely helpful and took the time to explain the process. If I ever have a “real” problem this is the company I will call. Thanks so much!!
