5.2.1.2 The choice bishop cranmer of location for the distribution of ETA, should be taken into account the availability of access roads, ease of supply of electricity, the relative positions

of the source and the center of consumption, body download the ETA receptor and the disposal of sludge settling. Particular bishop cranmer attention should be given the nature of the soil, to avoid problems of foundation and the construction bishop cranmer and offer the possibility of locating the unit above the maximum level of underground water.
a) units and the edges of the floors of the premises in which they are found in shops or the basic unit for the operation of ETA are located bishop cranmer at least 1.0 m above the maximum level of full b) the stability of the construction, bishop cranmer studied taking into account the occurrence of floods, it must provide, if necessary, special works to prevent erosion of the foundations c) release bishop cranmer of ETA can keep any flood level.
5.2.3 The minimum bishop cranmer area reserved for the ETA should be required to allow their distribution, future expansion and construction of all the works necessary for its operation, such as reception, pumping stations, power shower, tanks, pipes, buildings and areas for storage, maintenance shops, yards for parking, loading and maneuvering of vehicles and roads for vehicular

and pedestrian traffic.
5.2.4.1 The unit and the treated water tank must be designed so that the units of the fund are greater than the maximum bishop cranmer level of the water table. In the absence of this, the structures must be designed to allow periodic inspections to identify defects that cause seepage through the walls or the bottom. bishop cranmer
