Installing a tank in a high water level area is not always easy, but it's possible with careful planning and appropriate design. Here are the general steps to
1 Make sure you have permission to install in your area, if we are talking about a sewage system you want to make sure you are not in a area with a protected water course.
2 Soil and Site Assessment: Conduct a thorough soil and site assessment to determine the water table depth, soil conditions, and the suitable location for the tank. A percolation test will help determine the soil's ability to absorb effluent.
3 Selecting the Right Type of Tank: Choose a septic tank designed for high water table areas. We can provide tanks that are shallow dig, for instance if it is a rain harvester a Graf Platin tank will have a very shallow profile or with a sewage system we can also provide shallow dig tanks.
4 Proper Backfilling: When the tank is in place, ensure proper backfilling with suitable material around the tank to provide stability and prevent settling.
5 Effluent Disposal System: Design an appropriate effluent disposal system, such as a drain field or leach field. This system should be designed to handle the expected effluent load and should take into account the high water table. In some cases, a mound system might be required. This involves building an elevated drain field (mound) above the natural ground level to create better drainage and reduce contact with the high water table.
6 Regular Maintenance: After installation, perform regular maintenance, including periodic inspection and emptying of the tank, to ensure its proper functioning and longevity.
7 Consider Professional Help: Given the complexities involved in installing a septic system in high water table areas, it is recommended to work with a professional engineer or a septic system expert who has experience in such installations, give us a call and we can arrange for a consultation.
