Summary:The development and characteristics of advanced integrated wastewater ponding systems (AIWPS), which are modified sewage lagoon systems with at lest 4 lagoons in series, are described. The first lagoon is a deep advanced facultative lagoon in which sedimentation and methane fermentation take place in specially designed pits at the bottom of the lagoon. This is followed by a secondary facultative lagoon or, preferably, a high-rate lagoon with paddle-wheel mixing, by an algal settling pond and by a maturation pond with a retention period of 10-20 d. Diagrams of such a system and of the proposed advanced facultative lagoon are included and results obtained in the operation of such systems in California are summarized.
