A water provisioning device for use with an irrigation channel for providing water into an irrigation pipe. The water provisioning device comprises a primary reservoir adapted to maintain water up to a predetermined level and comprising a primary outlet adapted for being brought in fluid communication with the irrigation pipe. The system further comprises at least one primary inlet tube in the form of a siphon tube with a proximal end manually insertable into said channel for drawing water therefrom and a distal end adapted for the initiation of suction within the tube and for the disposition in said reservoir at least after the suction has been initiated, to supply said water thereto.

A process for conversion of organic wastes into biofertilizers such as soil conditioning agents of fertilizer grade, culture grade and soil grade is provided. Also provided is a process for conversion of organic wastes into material for converting waste water into reusable water. The invention provides methods for conversion of organic solid wastes to biofertilizers and reusable water in the presence of a geophagus earthworm Pheretima elongata culure to produce a variety of valuable soil conditioning products and reusable water.

The apparatus is a small flow wastewater treatment system. The system uses a recirculating packed media filter for the initial treatment of effluent from a device such as a septic tank. The incoming wastewater is furnished to the recirculating packed media filter intermittently to permit air into the filter for maintaining high levels of oxygen for bacteria action. The recirculating packed media filter is followed by a subsurface flow constructed wetland. The wastewater entering the apparatus of the invention is divided into two parts so that 5 to 25 percent of the incoming flow bypasses the recirculating packed media filter and goes directly into the subsurface flow constructed wetland to encourage bacteria action that converts nitrates into gaseous nitrogen.

A polluted water treatment system 10 operated to reduce impurities in sewerage polluted water to an acceptable level for dumping. The system includes a horizontal subsurface filter (HSF) 12 having an inlet zone 18 through which the inflow of polluted water is permitted to pass, a treatment zone 20 which permits the polluted water to undergo treatment by removal of at least some of the impurities of the polluted water and an outlet zone 22 from which the treated polluted water flows from the HSF 12. The impurities may include, for example, organic materials (BOD and COD) and oxidization processes within the HSF may reduce the quantity of the nitrites that are dumped from the outflow zone 22. The outlet zone 22 also includes a collection well 28 having a pump 30 located therein to recycle the treated effluent back to either the inlet zone 18 of the HSF 12 or to a secondary vertical filter 40. A level switch 26 located in the inlet zone 18 of the HSF 12 controls the level of water in the inlet zone to a set level 15 by regulating the amount of recycle water returned to the HSF 12 or indirectly via the vertical filter 40. The vertical filter 40 may be used to pre-treat any polluted water before it enters the HSF 12 and furthermore, it may also be used to remove phosphates from the polluted water.
