Leachate 300

Space saving, easy to install and lightweight – specifically designed for use in rural areas – with a capacity of 300 litres.

Every wastewater treatment system (both primary and secondary) requires a land application area to discharge the treated effluent. GRAF has developed a strong and durable arch trench drain (also refered to as leach drain) to achive this via absorption principle in the most sustaibable and efficient way.

• Ergnomically Designed & Engineered with ease of use in mind, a single module only weights 11kg.
• Once installed, the finished level can be used by heavy duty vehicles
• The infiltration tunnel can be loaded permanently up to 59 kN/sqm and thus is also suitable for lorry-bearing
• 5 years warranty
