Abstract (en)
[origin: EP0861947A1] A vacuum sewage handling assembly particularly for boats and recreational vehicles or caravans has a minimum of components because the conventional vacuum and holding tanks have been combined into a single substantially unreinforced, non-cylindrical, all plastic tank (25). The tank (25) has a contoured, convoluted, discontinuous surface (e. g. formed by grooves, channels, and other discontinuities 37, 44, 137, 87) so that it has no continuous flat surface area of more than about 200 square centimeters The combined vacuum and holding tank may mount a vacuum pump (53, 153), and optionally mounts a sewage discharge pump (59). The tank preferably has a generally parallelepiped configuration, and an interior volume of between about 45-65 liters, has a maximum vacuum level of about 26 cm of mercury, and is connected to other conventional portions (10, 11) of a vehicle toilet system, including outlets (19, 22) penetrating the exterior (18) of the vehicle. <IMAGE>
