G-M Services has a variety of services to offer. Please review the descriptions below and decide which one or which combination of services best fit your need. Feel free to contact us with any questions.

Well Performance Testing	A comprehensive evaluation of the well and well pumping equipment. The testing includes direct measurement of flows, water levels, discharge pressures, power consumption, sand production and vibration levels. The test normally includes measurement of all parameters at two (2) pump discharge pressures. These measurements are then used to calculate specific capacity, water horsepower, electrical input horsepower and overall efficiency of the pump/motor unit. The information is formatted in a report which includes water levels graph, pump performance curve and a brief evaluation of the condition of the equipment. This test can identify and quantify many problems, including issues within the well structure (holes in the casing/liner, separation in the casing/liner, restricted screen openings, excessive sand production) and pump related problems such as; worn bowl bushings, worn impellers, holes in the column piping, lower than optimal efficiencies and general poor performance of the pump. In addition, inspection and vibration analysis of the above ground pump and drive components can spot excessive shaft run-out, unbalance conditions in the motor and lubrication delivery problems.

Abbreviated Well Performance Testing	An abbreviated evaluation of the well and well pump. The test includes measurement of flow, water levels, discharge pressure and sand production at normal operating pressure only. This test can be utilized to regularly monitor a known problem. This test is also popular in the summer months when our customers are concerned about water levels and pump submergence.

Booster Pump Performance Testing	This test is similar to our well test, but for water distribution pumps.

Well Camera Surveys	A well camera survey is important to perform anytime you remove the pumping equipment from the well. Usually, a survey is conducted before and after any work is done to the well to identify problems and verify repairs. G-M Services' well camera can even be hung below the pump to determine where sand and other materials may be entering the well. Steve Kubala, G-M Services' camera operator, has been performing these surveys for over twenty years. G-M Services operates a color video camera capable of both forward and rotating side views. Color still photographs and up to three videos can be produced simultaneously and are available immediately after the survey.

Storage Tank Camera Surveys	Are you concerned about having to drain your ground storage tank to visually inspect the inside coating? Does sending divers into your drinking water make you nervous. G-M Services has an ideal solution to this problem, a remote controlled vehicle (ROV) mounted with a color camera. Steve Kubala is an experienced operator of this ROV and is capable of performing a very thorough inspection of the interior coating, including the roof. The ROV, which is dedicated to potable water systems, has been used to inspected the inside of elevated storage tanks and standpipes as well as smaller ground storage tanks. Perhaps the most important advantage of this survey is that you can leave your tank online before, during, and after the test...without wasting water or worrying about disinfection after the survey.

Flowmeter Repair and Calibration	When water accountability comes up short, you may have a flowmeter problem. The inner workings of a flowmeter can become worn and fail over time, resulting in inaccurate flow readings. G-M Services is experienced at repair and calibration of propeller style flowmeters as produced by manufacturers such as Sensus, Rockwell, Sparling and Water Specialties. We are also certified to complete meter testing affidavits reqired by the Harris-Galveston Coastal Subsidence District and the Fort Bend Subsidence District . If your meter is beyond repair, or it is not cost effective to repair your meter, G-M Services can find a suitable replacement for you.

Vibration Analysis	Through our association with Envibe our vibration analysis tools allow us to measure quantify even the smallest vibration in your pumping and distribution equipment. This services usually accompanies our full well performance test. It is recommended that vibration analysis be performed at least annually to ensure that your motors run smooth and efficiently. A report summary and spectrum of each measurement point are included in the final report.

Data Logger Sales and Rental	G-M Services is the local representative for Radcom® Technologies data loggers. These data loggers are capable of monitoring pressures, flows, levels, and many other types of input. Because they are battery powered, these data loggers continue to monitor your system in the most remote areas and in the toughest conditions. They are built to meet military specifications and are fully submersible. Radcom® data loggers are available with a comprehensive software suite for analysis and monitoring. Please visit the Radcom® website for more detailed information. G-M Services would be happy to sell or rent these data loggers to you depending on your needs.

Leak Detection	G-M Services has developed a system to determine when a water system's low flows are in line with expectations. As a result, minimum flow measurement can be compared to actual low flow conditions as measured during the test to determine if the system is experiencing excessive un-metered (leakage) usage. This test is usually run over the course of a week and is available any time of the year. Please contact us to schedule a test for you.
