Middle Trinity Groundwater Conservation District

Wednesday June 16, 2010 Registration officially begins in Coryell County. The registration office is located at 207 Lutterloh, Gatesville, TX. Our office space is in the old Gatesville hospital building. We would like to extend our gratitude to Bosque County for providing us with this registration office. Office ours are Monday, Wednesday and Friday from 9-4. Only existing wells may be registered at this office. All new wells (drilled after June 15, 2010) must be mailed to the home office with the appropriate registration fees. ($25 for registration and $200 security deposit for permitted wells. Security deposits are returned upon completion of the well and receipt by the District of the well completion log.) No monies will be excepted at the Coryell office. If you have any quesitons please call Sharon or Joe @ 254-965-6705.

Tips for completing well registration

Latitude and Longitude (GPS) Coordinates - Coordinates may be found one of several ways;

1. You may use the GPS system of your vehicle if it is possible for you to drive up beside your well.

2. Many cell phones now have GPS capabilities and may be used to find the coordinates of your well.

3. If you have access to a computer you may use any GPS location web sites to locate your property and click on the site of your well to obtain the coordinates. One such site is itouchmap.com. This website is simple to use and is one of the most accurate that we have found. Once on the web page, enter the address of the property that the well is located on. A satellite image of the property will appear and you may use the cursor to pinpoint the well location. The GPS readings will post below. The GPS format preferred by the District is degrees – minutes- seconds (ex 98.04.53)

4. If you cannot locate the GPS coordinates with any of the means listed above then you may contact a local well driller and they can take the readings for you. Most drillers will charge a small fee for this. However, it may be beneficial to have them take your readings because they are also able to help you determine other well information you may need such as casing size, discharge pipe size, depth, gallons per minute and the horsepower of the pump being used.

Well information

1. GPM-Gallons per minute may be estimated by using a gallon bucket and filling that bucket as many times as possible in one minute. This is easiest done at an outside tap but may be done in the bath tub if necessary.

2. Casing /Discharge pipe size -A normal household well will usually have a 4 inch casing with a 1 to 1 & 1/2 inch discharge pipe. If the well pumps over 17 gallons per minute the casing and discharge pipe may be larger.

3. Well Depth - If the depth of the well is not known you will probably need to have a well driller take that reading for you, unless you have a neighbor that has a well drilled near yours and they know the depth of their well. Then you would have a close estimate of the depth of your own well.

4. Pump Size - Most household wells that produce 17 gallons per minute our less will have a 1 to 2 horsepower pump installed. Anything greater than 17 gallons per minute would be higher. You may often find the size of the pump located somewhere on the well housing.
