In all aspects of our groundwater development and well design services, we provide the highest quality workmanship and materials. In addition, after our last piece of equipment leaves your site, we back up our promise of quality by providing the service and support that are required in the future. Preventive maintenance and problem-solving are the keystones in our time-tested method of well maintenance.
PREVENTIVE MAINTENANCE CONTRACT
To ensure consistent and professional upkeep of your groundwater system, we offer a preventive maintenance contract that provides for:
Annual or Semi-Annual Inspection
Coordination of Well Records
Overboard Testing
General Inspection and Immediate Correction of Any Problem
These are examples of the water during well rehabilitation, known as surging. Surging will continue until clear water is pumped out of the well.
Well rehabilitation through chemical treatment
Incrustation and bio-fouling of the groundwater formation, due to water quality, causes all groundwater systems to decline in productivity over a period of time. Chemical treatment is the process of treating wells, screens, gravel packs and adjacent water bearing formations to rid them of those materials that are reducing that well's efficiency by using approved chemicals along with mechanical agitation. We offer unequaled expertise in chemical treatment of wells. Our managers and technicians carefully analyze water samples, the well's history and the formations themselves to determine the specific chemical treatment and mechanical application that is best for each situation. Each treatment program is specially designed to meet the unique needs of the well involved.
The above image is a close-fitting stainless steel surge block that is used to rehabilitate a well.
In this image, our crew is using a water level gauge to measure the static water level before they begin surging. Readings of the static water level and pumping level during the rehabilitation process are beneficial in monitoring the progress over several days.
WHAT IS SURGING?
Surging is the process of the close-fitting surge block (left image above) repeatedly plunging into the well, in increments of 3' to 5', to complete a simultaneous 4-step process:
1. The close-fitted black rubber pads, located at the top and bottom of the surge block, rub the sides of the well, removing sand and silt that has gathered on the well screen.
2. The black rubber pads help form a loose temporary seal in the well screen so the water only flows through a 3' to 5' section of the screen.
3. The surge block channels the dirty well water to exit the well through the 4" or 6" surge pipe and out through a hose.
4. During surging, compressed air is injected through a 1" or 2" airline tube inserted in the 4" or 6" surge pipe to lift the dirty, sediment laden water out of the well. This process is professionally known as combination dual disc surging with airlift pumping.
Closed-circuit Tv well inspection
Downhole TV inspection, which permits us to pinpoint downhole problems and video record them for review. We can determine a well's problem in the screen or casing, carry out corrosion studies, analyze fishing operations and record the overall well condition. The downhole TV monitor delivers high-resolution pictures and an electronic counter tracks the depth of the camera at all times. This information permits our technicians to locate and identify well problems with a high degree of accuracy.
