This will show the proposed location of the system and the design of the percolation area in detail. It will also note the presence of rock or a high water table, in which case a rock -breaker or water -pump can be organised in advance. It is important to observe the EPA Separation Guidelines as shown below. See table 1. These show the minimum distance the system and percolation area may be from the house etc. FEATURE MINIMUM SEPARATION (m) Oakstown BAF Sewage treatment System Recommendations Oakstown BAF Sewage treatment System Irrigation Area Dwelling served 7111 10131 Adjacent dwelling 7111 10131 Wall 3111 3 Road 4(1) 4 Site boundary 3111 3 Portable water source 10 30 - 10012) Watercourse 10 10 Ensure that there is a solid unimpeded access for the Oakstown truck back to the hole. Clear any build up of clay from around the hole to allow the truck to reverse to within one metre of the hole, 0 In very wet conditions, it is best to leave the last few bucketfuls to be dug when the truck arrives. If the ground is rocky, it is advisable to dig the hole ahead of time to minimise delays on -site. 0 Ensure there are no power lines or other hazards above the excavation site. 0 Ensure that there is solid ground for the stabilising "jacks" to stand on. Do not dig trenches where a jack will need to stand. © We recommend an inspection chamber (AJ) be fitted just before the BAF Unit for maintenance. Digging Instructions j Oakstown BAF 6PE Wastewater Treatment System 1. Dig a hole 3200mm long [10'6"] by 2400mm wide [8ft] 2. Allow 1500mm from the bottom of the invert to the base of the hole 3. A bed of screenings will help to ensure a level surface for the tank 3200mm y.______________________________________._____--____)- 2780mm ® OW' Oakstown OAF 6PE + 11omm — E , �' OI Obi E NI a ' 32mm Inlet From S Hydrodaro Dwelling to percolation 110mm area Piping , I k--- Oakstown, Trim Telephone: 046 - 943 - 1389 E-mail: info@orelllyoakstown.com Co.

If in doubt, we can hold off on commissioning the system until the landscaping is finished and fit extra risers if required. Our driver will leave sufficient 7 -Core Cable to reach the house. Our technician will commission the system by installing the air blower, water pump and electronic controls and wiring them at the system. He will leave the "internal panel" for connection by your electrician to the mains with the most senior person on site. If there is nobody on site, it will be left inside the "Green Box" on the system itself. Percolation_ J O It is important to refer to the relevant Site Characterisation Report for size and design of the percolation area. The following diagram is only a simple outline. o� 25 - 40mm Screening Distribution N Box 32m Hydrodare 8 Trench Inlet From N Fall of 1:200 in Percolation Pipe Dwelling 110mm I 4m ..J......

Sample Percolation Area Only (NOT TO SCALE) Maintenance Please call O'Reilly Oakstown when moving in or when the system has been connected. Our technician will carry out a site visit to ensure the system has been wired, switched on and the risers are above the surrounding topsoil. A technician will visit the site to carry out a full service towards the end of the first year. eAF 6PE WTS :: 01/17 Oakstown, Trim Telephone: 046 - 943 - 1389 E-mail:info@oreiiiyoakstown.com Co.
