A sanitary sewer collection system transports sewage from homes and businesses within the City of Tallahassee Urban Service Area. This collection system is supported by over 100 pumping stations using approximately 150 miles of force main. These pipes that carry sewage are completely separate from the system that carries stormwater.
The Sewage Sludge Directive has been evaluated several times under EU proposals to build a circular economy through the reduction and reuse of wastes. [98] [99] In 2014, a European Commission evaluation of the Sewage Sludge Directive suggested it was appropriate for its goals, and did not need revision.
Public Law 100-688 terminated the dumping of sewage sludge and waste from industrial companies (commencing with the 270th day after November 18, 1988) under certain conditions. [11] After December 31, 1991, it was prohibited to dump any type of sewage sludge and industrial waste.
Mesophilic anaerobic digestion (MAD) is also a common method for treating sludge produced at sewage treatment plants. The sludge is fed into large tanks and held for a minimum of 12 days to allow the digestion process to perform the four stages necessary to digest the sludge. These are hydrolysis, acidogenesis, acetogenesis, and methanogenesis.
EPA created an Intra-Agency Sludge Task Force to aid in developing comprehensive sludge regulations that are designed to do the following: (1) Conduct a multimedia examination of sewage sludge management, focusing on sewage sludge generated by POTWs; and (2) develop a cohesive Agency policy on sewage sludge management, designed to guide the ...
Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste. It is a bacterial process occurring ...

In facultative ponds, sludge removal may be necessary only in intervals around 15 to 25 years. In maturation ponds, sludge accumulation is very low. [6] Sludge removal, also called desludging, may be done in two basic ways: (i) interrupting the operation of the pond for desludging or (ii) keeping the pond in operation while desludging. [6]
