The invention relates to a housing 1 for a micro-irrigation emitter which freely expels unfiltered turbid fluids containing suspended particulate matter, for the irrigation of plants. The housing comprises a thin-walled invert dished shape having a bottommost outer rim (2 figure 2) which rests upon the ground surface. Inboard from the rim the surface is solid and rises gently towards middle portion (4 figure 2) which rises up sharply to form a perforated domed surface within which an emitter 16 is secured. The invert shape ensures that the emitter is physically protected from above and that fluids drain out from below in their entirety. The ventilated portion 7 facilitates the free passage of air, water and water vapour. The combination of the outer solid surface and an internal impervious curtain wall 11 creates at least one air pocket (12 figure 2) to provide a degree of buoyancy for the housing. An irrigation supply hose 15 passes through the housing wall and is connected to the emitter and acts as a flexible tether or mooring enabling the housing to float on any accumulated slurry. A later embodiment relates to a method of employing said housing.
