The GRIP Limpopo documentation Wiki hosts all kinds of documentation related to groundwater and the purpose is to empower groundwater users by making relevant information available in a central repository!

Project Reports

The Mwamitwa, Glen Alpine and middle Lethaba dam projects are significant projects that contributed to the creation of the GRIP project or benefited from it. More details and reports available in this section.

Standard Specifications

This section contains a whole lot of standard specifications that can be used when designing lockable manholes for submersible pumps or upgrading a tank stand.

Status reports on groundwater Levels & Trends

Data and information on total rainfall, percentage of normal, percentage of long-term mean, shorter and long-term groundwater level trends are presented and discussed in this section. Groundwater level data is collected on a monthly basis, interpreted and reported on.

Satellite Images

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument onboard Terra, the flagship satellite of NASA's Earth Observing System (EOS) launched in December 1999. ASTER is a cooperative effort between NASA, Japan's Ministry of Economy, Trade and Industry (METI), and Japan Space Systems (J-spacesystems). ASTER data is used to create detailed maps of land surface temperature, reflectance, and elevation. The coordinated system of EOS satellites, including Terra, is a major component of NASA's Science Mission Directorate and the Earth Science Division. The goal of NASA Earth Science is to develop a scientific understanding of the Earth as an integrated system, its response to change, and to better predict variability and trends in climate, weather, and natural hazards.

The GRIP Team has been utilising this technology extensively to get satellite images of the Limpopo Province and these are available in this section of the documentation.

Water Quality Standards

Technical and managerial skills are essential in any institution if high performance and compliance are the expected outputs. With the right skill sets in place many infrastructural and resource challenges can be mitigated if not completely overcome. The inverse also holds true. The best water treatment plants and the biggest budgets cannot be made to comply without the right technical and managerial skills.

This Key Performance Area aims to measure compliance to the regulation Classification of Water Services Works and Registration of Process Controllers (currently draft, to be gazetted). It places a renewed focus on the Operational and Maintenance skills requirements with the ultimate goal of ensuring that adequately skilled staff is employed to take charge of process control, plant maintenance and management.

Information related to water quality standards are available in this section.

GRIP Processes

Over the years the GRIP project has been active, an extensive Data flow and quality control process has been devised to make sure that accurate groundwater data reaches the public. Diagrams available in this section.

Interpreted Maps

The data collected in the GRIP project are interpreted periodically to produce maps showing Abstraction Yield, depths, Nitrate concentration, TDS level and much more on maps. Some of these maps can be viewed in this section.

Field forms

The GRIP team has been using stvanderdised field forms to collect data in the field. These are available in this section.

Drilling guideline

When a request for a water supply project is received the following route is strongly recommended to achieve the required, most cost effective and most beneficial results. Read more here under this section.
