Onion Shape & Spherical Septic Tanks
Onion shaped spherical septic tanks are an ideal wastewater management tool in areas where there is no hard rock or high water table. This allows for greater excavation to position the septic tank with its increased height. Onion shaped septic tanks are easy to install and maintain. They are made up of two or more chambers in which raw sewage is treated through anaerobic digestion.
The effluent is then allowed to escape into a percolation pit in the ground, where the soil completes the treatment process. Solid sludge that remains in the primary settlement chamber is then removed from time to time and sent to a treatment facility. This prevents it from clogging the soak pit and preventing the bio digestion of waste.
Onion shaped septic tanks can further be fitted with an optional tank filter to reduce suspended waste in the effluent. This prevents odours and improves the quality of the effluent, prolonging the life of the percolation pit.
MP Tank Suppliers are top suppliers of high quality Glass Reinforced Plastic septic tanks. These are ideal for use in both domestic and commercial applications. GRP septic tanks are made from glass and 100% virgin resin with no chalk fillers. This is the perfect material for constructing a tough, long lasting and maintenance free septic tank.
