Residential development in coastal areas — specific challenges along the coast
Popenguine is a coastal town in the Thiès region, known for its vacation homes and beach. Installing an on-site sewage system there presents specific challenges: the proximity of the water table, the sandy coastal soil, and stricter requirements for marine environmental protection.
Tx-H2O has deployed a System O)) tailored to these conditions, ensuring effective treatment of domestic wastewater while protecting the coastal ecosystem.
Sandy soil and the water table: a custom-designed system
The coastal soils in Popenguine are highly permeable and have a water table close to the surface—two factors that require a high-quality impermeable geomembrane and precise sizing of the sand filter.
Installation steps
Permeability analysis, groundwater level measurement, and soil sampling for filter sand certification.
Excavation suitable for sandy soil, installation of a high-strength waterproof geomembrane.
Installation of the biological reactor, filling with tested filter sand, and connection to the residence's plumbing system.
Effluent quality testing, leak testing, commissioning, and issuance of compliance documents.
