GlobiWell is a South Africa based groundwater consultancy, borehole and water engineering company, operating from Port Elizabeth, which provides a large variety of groundwater, borehole and geophysical services.
GlobiWell’s major service focus is on scientific borehole siting, borehole infrastructure design and borehole equipping.
A useful service which GlobiWell can provide to civil and construction engineers, is geophysical surveys for geotechnical investigations. GlobiWell have conducted many Vertical Electrical Soundings for geotechnical investigations on Wind Farms.
GLOBIWELL SERVICES:
Groundwater Feasibility Study
Geological maps and borehole databases are studied to identify the groundwater potential of the study area; often performed prior to field investigation.
Scientific Borehole Siting
Field geological mapping in collaboration with geophysical surveys is used to site boreholes by skilled hydrogeologists, geologists and geophysicists. GlobiWell’s team assign allot of effort and time into siting the best possible boreholes for their clients.
BOREHOLE DRILLING AND DRILLING SUPERVISION
GlobiWell has a few skilled and profesional drilling teams, with excellent equipment which they utilize for their groundwater projects. A on site hydrogeologist will design the borehole construction, manage drilling teams and capture scientific data about drilling targets. The hydrogeologist will support and advice clients on decisions.
BOREHOLE TEST PUMPING AND Borehole pump YIELD RECOMMENDATIONS
GlobiWell conducts test pumping of boreholes. The raw data obtained from test pumping is analysed to provide a sustainable pumping yield recommendation to the client.
Borehole Rehabilitation
Boreholes which suffer from decreased flow rates over time due to biofouling can be treated and cleaned by a chemical and physical approach.
Borehole Grouting and sealing of artesian flow
GlobiWell develops and implements a strategy of sealing artesian borehole or sealing off saline water strikes.
Managing Groundwater Pollution
Risk assessments of ground contaminations are conducted, which involve water sampling and chemical analysis to assess spatial extend of contamination and severity. GlobiWell aims to identify the source of pollution and propose methods of rehabilitation.
Geophysical Surveys for Geotechnical Investigations
Electrical Resistivity Tomography is the geophysical method used to study the properties of sub-surface properties of the soil and rock which is needed for geotechnical investigations prior to construction.
Borehole Infrastructure Designs and borehole equipping
At GlobiWell complete borehole infrastructure/reticulation schemes are designed for small households to large scale farming irrigation systems and municipal water supply. The GlobiWell engineers are highly skilled.
Groundwater Dewatering Schemes
Designing and implementing the processes of lowering groundwater by pumping to prevent the ingress of groundwater into excavations or tunnels. Dewatering is often used in the field of construction or mining.
Groundwater Monitoring
Aquifer properties such as borehole water levels are recorded over time and the results are graphed. Any change in groundwater levels can be identified. This is crucial for managing groundwater resources in a sustainable manner.
Groundwater Sampling, Water Quality Tests, and
water treatment
Water samples are collected and analysed for drinking water standards, agricultural standards, and operational standards. If water does not adhere to the desired quality, GlobiWell can design and install water treatment plants.
Borehole Registration and Licensing
GlobiWell can submit necessary motivations and studies to the Department of Water Affairs to license the client’s borehole.
Borehole Electrical conductivity Profiling and Down Hole Camera Logging
Borehole camera logging is used to assess borehole structural integrity and geology.
Artificial Aquifer Recharge Schemes
Developing methods of inducing groundwater recharge.
