Wastewater treatment is not an option; it is a legal and environmental responsibility. Tx‑H2O guarantees you full compliance at every stage of your project.
In all the West African countries where we operate, regulations require that wastewater be treated properly before being discharged into the ground or the sewer system. Failure to comply with these standards can result in fines, but more importantly, it poses real health risks to your community.
Tx-H2O works closely with the relevant authorities—including ONAS in Senegal—to ensure that every installation, from residential to community-based, fully complies with the applicable legal framework.

Standards generally require a minimum distance of 10 to 35 meters between a wastewater treatment system and a well or water source, depending on the country and soil type. Thanks to the high performance of the BNQ 3680-910-certified System O)), we can often safely reduce these setback distances, with the approval of the authorities.
Our engineers can perform a free assessment of your existing system. We check for leaks, verify compliance with regulatory clearances, assess effluent quality, and ensure compliance with the original permit. If compliance adjustments are needed, we’ll recommend the most suitable and cost-effective solutions.
The risks are both health-related and legal. From a health perspective: contamination of the groundwater and the spread of waterborne diseases in your neighborhood. From a legal perspective: administrative fines, formal notices requiring you to bring the situation into compliance at your own expense, or even criminal prosecution in the event of proven pollution—not to mention your civil liability in the event of damage to your neighbors’ property.
Yes. The System O)) holds the internationally recognized Canadian BNQ 3680-910 certification, and Tx-H2O works in partnership with ONAS to have each installation validated. Several of our projects in Senegal have been carried out with the direct support of ONAS, notably the community project in Tivaouane.
