Do your mine water balances hold up under MR and DWS review?

We build the balance from stated inflows, outflows, and storage terms — rainfall, run-off, seepage, evaporation, process demand — with each term traced to a source (site data, regional records, or a documented assumption) so a Mine Residue or DWS reviewer can query any single number without unpicking the whole model.

Can you align TSF water management with GISTM as well as SANS?

Yes. Where a TSF falls under Global Industry Standard on Tailings Management commitments, we scope the water balance and flood-hazard components to support that reporting alongside the SANS design and safety requirements that already apply locally.

Do you handle pit dewatering, or only surface water?

Both. Pit inflow and dewatering studies — including sensitivity to rainfall variability and climate scenarios — sit alongside surface water balance and TSF work, since the two are rarely independent on an active mine.

What about flood hazard on the mining footprint itself — pits, dumps, TSFs, haul roads?

We assess flood hazard across the footprint as a single picture rather than site-by-site in isolation, since diversion berms, pollution control dams, and TSF freeboard all interact with the same design storms.

Can you support closure planning, not just an operating mine?

Yes. Post-closure flood and water balance behaviour — how the site responds once pumping and active management stop — is typically a distinct scenario from the operating case, and we scope it separately where closure planning requires it.

Do you work across multiple pits or TSFs on one operation?

Yes. Multi-facility operations are common — we apply a consistent methodology and design-event basis across pits, dumps, and TSFs on the same site so the results are comparable and a single reviewer can sign off the set.

Why mining operations work with us

A mine water balance carries consequences beyond the spreadsheet: under-estimate inflow to a TSF and you carry avoidable freeboard risk; over-estimate pit dewatering demand and you size pumping infrastructure the operation does not need. We build balances and flood assessments with each input term traced to a source — site monitoring data where it exists, regional records and a stated assumption where it does not — so a Mine Residue, DWS, or internal technical reviewer can verify the number rather than take it on faith.

Tailings-related work is scoped against SANS and, where GISTM commitments apply, against that standard’s water-management and flood-hazard expectations too. We treat the two as complementary requirements rather than picking one over the other.

How we work with mining operations

Typical engagements include:

Mine water balances. Full-site or facility-level water balances covering rainfall, run-off, seepage, evaporation, and process demand, scoped to support water-use licensing, MR reporting, or internal planning.
TSF water management and flood hazard. Water balance, freeboard, and flood-hazard assessment for tailings storage facilities, aligned to SANS and, where applicable, GISTM.
Pit dewatering and inflow studies. Pit inflow estimation and dewatering demand, including sensitivity to rainfall variability and climate scenarios, feeding pumping and storage design.

We are used to working across NEMA and National Water Act requirements alongside a mine’s own technical governance, and can scope work as a single facility study or a consistent methodology applied across a multi-pit, multi-TSF operation — including closure-stage scenarios where the operating case no longer applies.
