Environmental Regulations
Depending on your location, there may be stringent regulations governing septic systems to protect the environment. Be sure to consult local guidelines and work with licensed professionals to ensure compliance and avoid costly mistakes.
System Suitability
Leach drain systems come in various types, such as conventional septic tanks, advanced treatment units (ATUs), and drip distribution systems. Consider the specific characteristics of each system and match them to your site constraints and soil conditions. For instance, ATUs are ideal for small lots or properties near water bodies, while drip distribution systems are suitable for uneven terrain.
Maintenance and Cost
Different leach drain systems have varying maintenance requirements and upfront costs. Plastic leach drain systems are generally more cost-effective than concrete alternatives due to lower manufacturing and transportation costs. They are also lightweight and easy to install, reducing labour expenses. However, plastic systems may be more susceptible to crushing during installation or root penetration over time, leading to potential blockages.
In summary, choosing the right plastic leach drain system involves carefully considering soil type, water table levels, environmental regulations, system suitability, and maintenance and cost implications. By selecting the most appropriate system for your specific circumstances, you can ensure effective wastewater treatment and disposal while also complying with local regulations.

Preparing the installation site
Before installing plastic leach drains, it is important to carefully prepare the installation site. Here are the steps you need to follow:
Firstly, determine the size and scope of the project. This includes deciding on the required length, width, and depth of the leach drain system. Consider the amount of liquid waste that needs to be disposed of and the type of soil around the installation site. These factors will influence the design and layout of the leach drains. It is important to plan the installation carefully to ensure compliance with regulations and to obtain any necessary permits or approvals.
Next, clear and level the installation site. Remove any debris, vegetation, or obstacles that may interfere with the installation. Use appropriate tools and equipment to grade and compact the soil, ensuring a stable base for the leach drains. Ensure the site is easily accessible for delivery of materials and equipment. This includes creating a clear pathway for vehicles or machinery that will be used during the installation process.
Then, mark out the installation area. Use stakes and string to outline the perimeter of the leach drain system. Ensure that the markings are accurate and align with your design plans. Take measurements and double-check all dimensions to ensure they meet the requirements of your specific leach drain system.
After that, excavate the site. Dig trenches according to the specifications of your leach drain system. Follow the manufacturer's instructions for depth, width, and spacing between trenches. Ensure that the trenches are straight and level, using appropriate tools such as a transit level or laser level for accuracy.
Finally, prepare the trenches. Before placing the leach drains into the trenches, it is important to line them with a geotextile fabric or filter wrap. This will prevent soil or sand from migrating into the drains and maintain the system's efficiency. Ensure that the fabric or wrap is securely in place and covers the entire trench area.

Assembling the leach drain components
The Drainwell Plastic Septic Leach Drain, for example, offers flexibility in terms of pipe connections. It features a 90mm and a 150mm cut-out guide, accommodating pipes up to 225mm OD PVC. This makes it suitable for both new builds and existing homes.
When assembling the components, follow the manufacturer's instructions carefully. Most leach drain systems are designed for easy installation, with lightweight materials and panels that clip together by hand. The Drainwell system, for instance, features panels that clip together easily.
Additionally, consider the design factors that govern leach drains, such as the size of the drain, the amount of liquid waste to be disposed of, the type of surrounding soil, and the construction method. These factors will influence the assembly process and the final configuration of your leach drain system.
For added protection, you can wrap the modules in a geo-cloth filter wrap to prevent sand from filling the leach drain. Once installed, water the sand into the plastic matrix lid, which will protect the tank beneath.

Connecting the leach drain to the septic tank
Before connecting the leach drain, it is essential to understand the function of the septic system. The septic tank is where solid waste settles, and the treatment area, or leach field, is responsible for disposing of liquid waste effluent. After the waste is broken down by bacteria in the septic tank, the effluent moves to the leach lines, where it drains into the ground.
Now, for connecting the leach drain to the septic tank, follow these steps:
- Planning: Ensure that you comply with local regulations and have the necessary approvals. Determine the ideal location for the septic tank and leach field, considering the required distances from buildings, wells, streams, and property lines.
- Excavation: Dig a hole for the septic tank, at least 2 feet deep. Drill a hole through the wall or go under the footing if necessary. Remember, the flow should go downhill towards the leach field.
- Piping Installation: Install the pipes that will connect the septic tank to the leach field. Use a 4" Sch. 40 pipe for the initial section, ensuring it is level as it goes through the wall or footing. Then, slope it towards the septic tank at about an 1/8" per foot pitch. Adaptors and different pipes may be needed for the rest of the piping.
- Leach Drain Connection: Connect the leach drain to the outlet pipe of the septic tank. Ensure that the perforated pipe is laid dead level, with the printed line facing up. All sections of the perforated pipe should be glued together, and the end of each leach line should be capped.
- Effluent Distribution: The effluent will flow from the septic tank into the leach pipes. It will then trickle out of the holes in the pipes and percolate downward through gravel and sand before reaching the soil. Ensure that the liquid percolates at the correct rate to avoid flooding or backing up the system.
Remember to refer to local guidelines and regulations throughout the installation process, and don't hesitate to consult professionals if you have any doubts or concerns.

Testing and maintaining the leach drain system
Testing and maintaining a leach drain system is crucial to ensure proper functioning and longevity. Here are some detailed instructions for testing and maintaining your plastic leach drain system:
Testing the Leach Drain System:
- Perc Test: Before installing a leach drain, it is essential to conduct a percolation (perc) test to evaluate the soil's absorption rate. Different soil types have varying drainage capabilities, with sandy soils draining faster than clay soils.
- Load Test: To test the drainage capacity of the leach field, run about 150 gallons of water into the tank in a short period and observe if the water drains properly or backs up. If the field is blocked by roots or clogged, it may require a new leach field.
- Tile Probe: Insert a tile probe into the gravel to check for water saturation. If the gravel is full, you may feel suction when pulling the probe out, and there could be water pressure in the trench, leading to effluent surfacing.
- Visual Inspection: Look for signs of collapse or damage, such as a massive hole in the absorption area, which indicates a potential issue with the drain field.
Maintaining the Leach Drain System:
- Regular Inspections: Get your septic system and leach field inspected regularly by a professional. It is recommended to have your leach lines and sewage system pumped every few years to remove scum and maintain proper functioning.
- Avoid Blockages: Do not flush grease, harmful chemicals, non-biodegradable products, or toys (if children are around) down the drains. Practice water conservation to reduce the risk of overloading the system.
- No Heavy Objects: Refrain from placing heavy objects, such as storage sheds or above-ground pools, over the leach field. Driving over the leach field should also be avoided.
- Annual Check-ups: Get your septic system checked annually by a qualified professional, and ensure the septic tank is pumped every 3 years to prevent build-up and maintain efficiency.
By following these testing and maintenance guidelines, you can ensure the proper functioning and longevity of your plastic leach drain system, protecting your investment and maintaining a healthy wastewater disposal system.
