Services
Sewage Treatment Plants
We design and install advanced sewage treatment plants that convert wastewater into environmentally safe effluent. Our systems comply with current legislation, reducing pollution risks while ensuring long-term reliability. Ideal for properties without mains drainage, these plants require minimal maintenance and are tailored to property size and usage.
Septic Tanks
Our septic tanks provide efficient on-site wastewater storage for rural properties. We supply and install durable, low-maintenance tanks made from robust materials. Regular servicing ensures optimal performance, preventing leaks and environmental contamination while adhering to local authority requirements.
Cesspools
Cesspools offer sealed containment solutions for properties where discharge to drainage fields isn't feasible. We install compliant units with sufficient capacity for seasonal or high-occupancy sites. Regular emptying by licensed operators ensures legal compliance and prevents overflow risks.
Soakaways
We construct soakaways to disperse treated effluent safely into the ground. Our designs consider soil permeability and site conditions, ensuring effective drainage without groundwater pollution. Properly sized soakaways extend system lifespan and maintain environmental standards.
Installation Service
Our expert team handles complete system installations, from excavation to commissioning. We coordinate with local authorities and utility providers, ensuring minimal disruption. Projects include pipe routing, electrical connections for treatment plants, and site restoration to pre-work conditions.
