How to install Sewage Treatment plant?
Step 1: Evaluate the regulations
When you consider all of the legal issues, installing an off-mains drainage system might be a scary concept. Everything from the sort of tank that is appropriate for a property or an industry to where it may be put, where it can discharge to, and what kind of ground conditions are allowed, is governed by laws and regulations.
Step 2: Inspection of the area
Before you can consider purchasing a sewage treatment plant area and constructing a sewage treatment plant, you must first assess the installation area to determine the sort of system required.
Do you require any form of permit for purchasing the land?
A permit would also be required if the new discharge will be in or near:
1: Within 200 meters of an aquatic local nature reserve;
2: Within 50 meters of a chalk river or aquatic local wildlife site.
Step 3: Establish the infrastructure
Your site survey results will all have an influence on the design of your system. Now is the time to start looking for a sewage treatment plant that meets your requirements.
Calculations that are required:
1: Choosing the appropriate tank size for your needs;
2: Determining the drainage field's size.
How can you calculate the size of a sewage treatment plant?
Most sewage treatment facilities are classified according to the population they can serve; you could believe it's as simple as matching the category to the number of people lined in the property.
Step 4: Configuration of the tank
This is where we restate our advice that sewage treatment system installation should always be performed by a professionally trained and competent expert. Stages in the construction of a sewage treatment facility include:
1: Analysing the tank for damage
Make careful to full check on tanks when it is received, because most manufacturers will not accept claims for damage after the tank is fitted.
2: Double-check that your invert depths are accurate
During the site survey and design stages of your project, you should have evaluated the depth of your incoming pipes and bought a tank with the necessary invert levels.
3: Locating the tank
Check your chosen installation site against the installation manual's requirements, as they may prescribe additional conditions and minimum distances particular to their tank.
4: Dig the hole
Check that it is large enough to accommodate the tank and any necessary backfill, then build the appropriate sort of base (typically concrete) for the tank to sit on.
5: Think about drainage falls
This should have been part of your planning from the start, but it's always worth double-checking, especially with a gravity system. These are typically 1 in 60/70 between the house and tank, with a maximum of 1 in 200 for a drainage field.
6: Place the tank
Carefully lower the tank into the hole, using the recommended lifting system, while checking that the inlet and outlet orientation is correct and ensuring the tank is level.
7: Use the proper backfill
The most typical recommendations are concrete, gravel, or sand, but read the instruction manual to see what the manufacturer recommends and follow their methods for adding backfill to the site.
8: Connect the inlet and outlet
Assuming that everything has gone according to plan thus far, connecting the pipe work should be quite simple. It is worth mentioning, however, that some manufacturers recommend installing inspection chambers before and after the treatment plant to provide for simpler maintenance access in the event that difficulties occur in the future.
9: Connect the electrical wires
Leave any electrical work to a professional unless you are a certified electrician.
10: Use the proper cover and frame
Assuming you gave the necessary site data to the sewage treatment plant supplier/manufacturer, the most appropriate cover and frame should already be delivered.
11: Take ventilation into account
This is sometimes forgotten, but it is critical to ensure that your system is properly ventilated to avoid odour concerns on the job site. Ideally, there should be a vent on the treatment plant as well as venting at the ends of the percolation trenches if you have a drainage field.
Step 5: Execution
A sewage treatment plant's biological treatment process is largely self-regulating and does not require specialized skills to run. However, it is critical to understand how it works and that there are certain limitations to using it as compared to a standard mains sewer connection.
Step 6: Maintenance
You should have prepared for future maintenance demands before establishing your sewage treatment facility.
