Odor changes
New or persistent sewage odors may indicate overload, poor pretreatment, biological imbalance, or maintenance failure.
WASTEWATER TREATMENT SYSTEM RWANDA
A practical commercial guide to DEWAT, odor control and maintenance.
Our first priority article explains how to assess septic-tank alternatives and decentralised wastewater treatment for Rwanda and East Africa.
RESPONSE TO THE NEW TIMES
Can decentralised sewer systems solve Kigali’s sanitation challenges?
ALUVIA responds with a building- and premises-level implementation pathway for Rwanda.
MYTH CHECK · HIGH-RISE WASTEWATER
Does Burj Khalifa really remove sewage by truck every night?
We fact-check the viral claim and explain the real technical lesson for commercial buildings and DEWAT systems.
FEATURED RESPONSE
From sanitation ambition to local treatment.
Our engineering response to the discussion on cell-level decentralisation in Kigali: how building- and neighbourhood-scale wastewater treatment can become phased, verifiable infrastructure.

WWTP PERFORMANCE
7 signs your wastewater treatment plant needs attention.
Persistent odors, cloudy or unusually colored outlet water, solids carryover, abnormal sludge, unstable flow, repeated alarms, or laboratory results outside the project objective all require investigation. A visual check is useful, but it cannot confirm compliance.
Outlet appearance
Cloudiness, solids, foam, or strong color can reveal separation or biological-treatment problems.
Data and testing
Review pH, EC, operating status, sampling records, and accredited laboratory results together.
RWANDA COMPLIANCE
Are you ready to demonstrate RS 110 compliance?
Compliance depends on the applicable discharge objective, representative sampling, recognized laboratory testing, correct operation, and traceable records. Online monitoring supports control but does not replace compliance testing.
Know the outlet
Confirm where the treated water goes and which requirements apply.
Sample correctly
Use a representative sampling point, timing, method, preservation, and chain of custody.
Act on results
Compare results with the applicable objective, document corrective actions, and retest as required.
WWT ESSENTIALS
From inlet to a verified treated outlet.
Wastewater from a building or premises requires appropriate upstream pretreatment. Where a commercial kitchen is present, a correctly sized and maintained grease separator is mandatory. The ECOFLOW pathway combines controlled inlet, transfer, decantation, MBBR with ALUVIAMEDIA-supported biofilm, active biological filtration, UV final treatment, and smart operational monitoring.
