SECONDARY PACKAGED WASTE WATER TREATMENT SYSTEMS RECEIVING RAW WASTE WATER In recent years, many types of secondary packaged treatment systems have come on the Irish market. These may offer solutions for the treatment of domestic waste water, particularly in situations where septic tanks and percolation areas are inappropriate but the site has percolation values between 3 and 90. Such packaged waste water treatment systems treat raw waste water using bespoke media and mechanical parts to provide the conditions for secondary treatment. Such systems are required to meet the treatment standards of 20 : 30 : 20 (mg/l) for BOD5, suspended solids and ammonium nitrogen (NH4-N). They also reduce concentrations of microbial pathogens and provide partial nitrification. These systems must meet SR 66 and I.S. EN 12566 Part 3 standards. Confirmation of testing and compliance of performance with SR 66 should be checked. Where ground discharge is proposed, a secondary packaged waste water treatment system will require a polishing filter, low-pressure pipe distribution system or drip dispersal system, which will allow for further treatment of the waste water and will also convey the treated waste water to ground (see Chapter 10, especially Table 10.1, for infiltration/treatment area design). Although all systems tested to standard I.S. EN 12566 Part 3 are treated similarly in terms of use, level of treatment and functionality, each individual system should be checked to ensure that it matches the infiltration/treatment area design for a site. A typical layout for the treatment of waste water using any secondary packaged waste water treatment system that must meet these requirements is illustrated in Figure 9.1. Figure 9.1: Example of a typical packaged system and polishing filter system If the treated effluent is to be discharged to surface water, the required effluent quality will be dictated by the conditions of a water pollution discharge licence and tertiary treatment may be required. Many systems are available on the market, including the following generic treatment types: \biological/submerged aerated filters (BAFs/SAFs); \rotating biological contactors (RBCs); Manhole (change in direction) Dwelling Packaged Treatment System 7m (min) 10m (min) 10m (max) Soil/Sand Polishing Filter (gravity fed) Power Cable Distribution Box Manholes RECEIVED: 26/03/2026 RECEIVED: 26/03/2026 RECEIVED: 26/03/2026 RECEIVED: 26/03/2026 Geo logical Survey Irelan d © Tailte É ireann | Tailt e É ireann | G eologi cal Su rvey Ire land | Teagas c, EPA & GSI | Env ironmental Pro tec tion Ag ency | Thi s m ap a nd its d a ta m a y no t b e u se d o r r ep ro d uc ed fo r co mm er ci al pu rp o se s w ith o ut th e p ri or w ri tten p er mi ssi on o f C o p yri gh t h ol d ers .
