Do wastewater treatment plants require drainage systems?
Poor sanitation has been linked to an increase in morbidity and mortality. Excreta and wastewater disposal are critical components of sanitation. Improper biodegradable waste disposal can spread diseases and pollute the environment.
Owners should plan for a drainage and sewage system to ensure safe sewage disposal and avoid water stagnation.
General drainage and wastewater treatment plant guidelines
• The drainage system should be closed, with no open drains on grounds
• All open drains should be properly covered
• Drainage system gradients should be conducive to maintain water flow
• All drains should be checked for blockages on a regular basis
• Regular cleaning (preferably once a week) of the drains is required, in accordance with the cleaning schedule
• The drainage and sewage system should be connected with the municipal sewage and drainage system
Connection to the Sewer Main
When reviewing drainage options for off-mains properties, the first step is to look for ways to connect to the main sewer, wherever possible.
If a gravity feed to the main sewer is not feasible, a pump station can be installed to allow for a connection. Again, a suitably qualified engineer should conduct an on-site survey, to determine whether either option is feasible.
If not, the owner will have to manage their wastewater on-site.
Options for Off-Mains Drainage
Septic tanks and sewage treatment plants are two of the most common off-mains drainage systems, but their operation and efficacy vary greatly.
1. Sewage Treatment Plants
STPs are extremely effective at managing wastewater, regardless of their location or underlying ground conditions.
A sewage treatment plant (STP) provides an environment in which aerobic bacteria can be cultured, and used to break down sewage. This is a highly effective and efficient process that removes up to 95% of pollutants from wastewater, before it is discharged.
"Packaged" sewage treatment systems are STPs that are supplemented with tertiary treatment, such as a packaged reed bed. With an efficiency rating of up to 98 percent, these are the current "gold standard" in off-mains drainage. They generate a clear, odourless effluent that is environmentally friendly and safe to discharge even in sensitive areas, such as a watercourse.
STPs, contrary to popular belief, should not be significantly more expensive than septic tanks, when installation and maintenance are considered.
Conclusion
It's encouraging to see that off-mains drainage legislation has become more stringent in countries, around the world in recent years. However, the decision in some markets to relax legislation and reporting requirements has alarmed, drainage management professionals.
Our main point is that off-mains drainage should always be professionally designed and specified. The architect/specifier, developer, installer, and property owner are all morally and legally obligated, to dispose of wastewater in a safe and considerate manner.
Any effort to reduce the administrative burden on property owners, should never be misconstrued as permission to act irresponsibly, and an owner's personal liability remains unaffected.
