NEMA standards have tightened. We supply equipment that passes.
Failing inspection halts production. Donor-funded projects gate on compliance. We supply the tanks, instruments, and analyzers that pass NEMA discharge standards under EMCA CAP 387. The parameters table is on this page; no other Kenya supplier publishes it.
ETP is the one industry where compliance is the brief.
The other industries buy infrastructure because they're growing. ETP buyers buy infrastructure because they have to. The trigger is almost always external: a NEMA inspection that flagged a parameter, a discharge deadline, a donor project that gates on compliance, or a new effluent standard from a sector-specific regulation.
Speed matters more than anywhere else on the catalogue. So does the answer to one question: will this equipment pass the next inspection? Everything on this page is designed to make that answer yes.
Maximum permissible levels per EMCA CAP 387.
Designed for the operator preparing for a NEMA inspection. First column: parameter. Second: limit for direct environmental discharge. Third: limit for discharge into a public sewer. The two limit sets are different; the right one depends on your discharge route.
| Parameter | Environment | Public sewer | Unit / notes |
|---|---|---|---|
| Biochemical Oxygen Demand (BOD₅) | 30 | 500 | mg/L, 5-day, 20°c |
| Chemical Oxygen Demand (COD) | 50 | 1000 | mg/L |
| Total Suspended Solids (TSS) | 30 | 250 | mg/L |
| pH | 6.5 to 8.5 | 6.0 to 9.0 | |
| Total Nitrogen (TN) | 10 | 20 | mg/L |
| Total Phosphorus (TP) | 2 | 10 | mg/L |
| Ammonia Nitrogen (NH₃-N) | 10 | 20 | mg/L |
| Oil and grease | Nil | 10 | mg/L |
| Conductivity | 1500 | 3000 | µS/cm |
| Temperature | ≤ ambient + 3 | ≤ 40 | °C, above receiving water |

What sits between your effluent and the discharge point.
We supply equipment inside the ETP scope. For full-plant design, we work alongside ETP designers; for retrofits and equipment swaps, we work directly with the plant.
- 01
Equalization & primary
Bolted zinc-alum equalization tank, epoxy-lined primary clarifier feeds.
- 02
Aeration & biological
Stainless aeration headers, dissolved oxygen instrumentation, sludge return loops.
- 03
Secondary clarification
Epoxy-lined secondary clarifier, level transmitters for sludge blanket monitoring.
- 04
Tertiary & polishing
Stainless polishing tanks, multi-parameter analyzer for compliance reporting.
- 05
Discharge & monitoring
Electromagnetic flow meter on the discharge line, continuous logging for NEMA reporting.
For plants under continuous monitoring obligations, every analyzer we install can stream parameter data 24/7.
Live pH, conductivity, DO, turbidity, and flow rate, with alarm logs you can hand to the regulator on demand. Hosted by us, or pushed into your existing systems. Safaricom NB- IoT for low-bandwidth sites.
