Sewage treatment, biodigesters and STP plants in Zanzibar
Clean discharge, compliant plot

Sewage handled. No smell, no trouble.

NEMC compliance is non-negotiable and hotels cannot afford odour complaints. We design, install and maintain biodigesters, packaged STPs and greywater reuse — one accountable team for villas, hotels and commercial plots across Zanzibar.

Why treat with us

Sanitation your neighbours never notice.

Hotels run on reputation — one smell complaint costs more than a treatment plant. We engineer silent, odour-free compliance.

NEMC-ready paperwork

Design reports, effluent test results and permit documentation prepared for compliance.

No-smell design

Sealed anaerobic stages, venting and correct sizing — no odour at the boundary.

Hotel duty-standby

Duty-standby blowers and pumps with auto changeover for properties that cannot stop.

Reuse saves water

Greywater and treated effluent recycled to gardens — lower borehole and ZAWA bills.

Our process

From problem plot to compliant discharge

A tested sequence — sized to flow, soil and NEMC requirements.

  1. 01

    Assess & quote

    We visit, check flows, soil and levels, then quote the right system with full installed cost.

  2. 02

    Design & permits

    System sized and drawn, NEMC paperwork prepared, civil and drainage works scheduled.

  3. 03

    Install & commission

    Biodigester or STP installed, soakaways built, reuse plumbed and the plant commissioned.

  4. 04

    Test & maintain

    Effluent tested, compliance file handed over, and a service plan keeps it clean.
