According to an article in Waterworld Magazine, “Septage receiving systems provide municipalities a means to manage the wastes being generated within their jurisdictions. This provides protection for their own systems as well as the environment. With systems provided, waste can be tracked from the original generator and allow only permit-approved materials to be dumped."
Septage Receiving Equipment
Plants are equipped with various types of septage reviving equipment. At the very least the plant will have a valve and controller as well as a screening device.
Other plants with more involved systems may have things such as a solids conditioning grinder, flow measurement device, ph meters and more.
Some plants are finding that a grinder combined with a special control system is a better method for keeping track of hauler loads.
Many plants are installing data collection control systems. In order to comply with EPA requirements the sources and volumes of septage needs to be recorded. Some plants are able to keep accurate records by giving their haulers a magnetic card.
While a magnetic card is designed to identify the hauler, there are inherent limitations and disadvantages to using magnetic cards and there are many better alternatives.
Once the hauler’s identity is confirmed, the hauler’s load can then be released, measured and analyzed.
The totalized gallons discharged as well as the date and time will be recorded. The entire transaction is recorded in a database for billing purposes, analysis and accountability purposes.
One of the concerns involved with septage receiving is addressing weather issues. Efforts need to be made to insure the system being utilized does not freeze during cold weather.
It is important to have weather-proofing that is able to maintain all lines and tanks above freezing.
In places where heat is a concern, controllers can be put in a protected area so they are not in direct contact with the sun.
