Hydrological Impact Assessments

Water is essential in our daily lives, and we all have a role to play to respect and understand our water sources so that we can manage them better. Hydrological data can help us to prepare and plan for extreme events by identifying where the risks are highest. Day to day hydrological data is used to manage our water resources in ways that suit our economic and environmental needs. Hydrological impact assessments are particularly useful to property planners and developers as they can alert them to any issues.

Letsolo Water and Environmental Services takes the time to thoroughly identify and establish watercourse locations that are suitable for the accurate measurement of water flow. We identify and delineate all surface water catchments in the affected area. We also determine the status of any surface water resources within the affected area in terms of water quality, in-stream flow, riparian habitat, and aquatic biota. In addition, we can identify sensitive downstream users of these water resources and determine the 1:100-year flood line of all watercourses within the affected areas. Letsolo Water and Environmental Services can also assess potential impacts of proposed developments on water resources, in line with legislation, and determine suitable mitigation measures towards sustainable and environmentally sensitive developments.

Process and Storm Water Management

The term “process water” refers to water used in industrial processes, manufacturing processes, and power generation applications, among others. Due to its ability to pollute the environment, Letsolo Water and Environmental Services works to ensure that any water in the process water system, as well as other contaminated water, is collected and contained in a process water circuit.

The process water circuit is isolated from the dirty stormwater system. Unless the stormwater is absorbed into the process water circuit by a controlled intake device as make up water, stormwater is collected in a stormwater dam. Letsolo Water and Environmental Services can design a site-specific storm water management plan for management of clean and dirty site catchments, such that dirty runoff is under control. Water is then collected, and excess process water is contained in a dedicated pollution control dam. This control dam is designed to have a spillage frequency of not more than once in 50%.

It is up to Letsolo Water and Environmental Services to ensure that the dam has a dedicated 0.8-meter freeboard that is above the dam’s full supply level. This ensures the long-term integrity of the dam unless otherwise specified in terms of Chapter 12 of the National Water Act 36 of 1998. It is also our responsibility to make sure that the dam is equipped with a suitably sized spillway to pass floods to the dirty area. Depending on the risk posed by the impounded contaminated water, we ensure the dam is equipped with a basin barrier properly engineered to protect the local water supply. To ensure optimal dam storage capacity, we provide the dam with suitable-sized, cleanable upslope silt traps.

As far as is practical, we ensure that water used in all mine processes is recycled and that any facilities, sump, pumping installation, pipes, and channels used for recycling water are designed and equipped adequately. This prevents spills, seepages, or releases of contaminated water. To keep the process water management infrastructure efficient, we make sure that any matter or obstruction is removed.

Lastly, we ensure that process water is not stored in underground workings, open-pit excavations, or mining voids.

Mine Residue and Stockpile Management

Letsolo Water and Environmental Services will maintain and operate any dam or any residue deposit or stockpile, as well as any other facilities containing hydraulically transported substances. This ensures that residue or other material will not result in their failure or impair their stability. We take great care to ensure that no substance which has the potential to contaminate water is used for the construction of any dam or other impoundment, or for any other purpose which is likely to cause pollution of a water resource.

Post-Closure Water Management Planning

Letsolo Water and Environmental Services presents a post-closure mine water balance. According to Regulation 10, we act to maximize the use of pollution prevention measures based on the assessment of the long-term impacts of closure management actions on water resources. We also define monitoring programs that should be implemented to collect data. This data will allow for scheduled future updates and improvements.

Hydropedology

Put simply, hydropedology is the study of water movement through the soil. The study of hydropedology involves soil morphology, soil water measurements, hydrological modelling, and conceptual hydrological response models to understand the movement of water through the soil. This information is then interpreted for the specific need, be it the extent of pollution, natural wetland functioning, town planning or catchment management. Letsolo Water and Environmental Services can assist with hydropedological assessments, a key requirement for water use license application where wetlands may be impacted. This study is a small-scale version of what is happening in soil science. Letsolo Water and Environmental Services is targeting farming communities to increase crop yield as well as mining entities to quantify the impact of mining on flow transport through the soil. Our vision is to create a site-specific analysis, not only for food production, but also for climate change, ecology, preservation of natural resources, forestry, and carbon sequestration.

Environmental Control Officer Services

Due to the introduction of activities in an undisturbed environment, there is need to monitor and mitigate impacts as soon as they occur. The services of an Environmental Control Officer (ECO) are essential to quickly identify impacts and immediately rectify, mitigate, or rehabilitate where possible. Letsolo Water and Environmental Services has ECO consulting services that are independent and environmentally professional to advise towards continuous improvement of site operations from construction, operation through rehabilitation stages of development. Our timely reporting of environmental aspects with suggested recommended action plans will assist developers in environmental compliance and environmentally friendly site operations. We can also assist in tracking resource use and production, by creating a site operation specific month to month dashboard for record keeping and easy annual assessments.
