The present invention is a new process for preserving the water of an aquatic body as a supplying source for different human activities such as recreation and amusement, food and ornamentation, by the development of a aquatic space formed by a Open water Lake, a Spa Lake, and a Water Depuration Lake that preserves the water mass by biotransformation and mineralization that allow reducing the concentration of carbon, nitrogen and phosphorous, generating clean and transparent water without the use of large amounts of chemicals and complex filtrate systems.

A prefabricated former for an underground pump station comprises: a floor former; a plurality of vertical support elements; a side wall secured to and surrounding the plurality of vertical support elements, the side wall having an inner layer and an outer layer defining a cavity therebetween, and an opening at an upper end of the side wall in communication with the cavity for receiving concrete, the side wall extending both above and below the floor former for defining a space above the floor former and a space below the floor former, and an opening being provided between the cavity and the space below the floor former enabling concrete to flow through the cavity and into the space below the floor former; when set, the concrete forming a unitary wall and base.

A system and a method of aerating well water using an aeration system comprising a well water drop pipe approximately vertically positioned having a bottom end in a well below the pumping level of the well water. Attached to the bottom end of the pipe is a submersible water pump, and a limited check valve is fluidly attached above the water pump. A flow restrictor is fluidly attached above the limited check valve to limit the flow of water up the pipe, and above the flow restrictor or the check valve is fluidly attached a bleeder to allow air to flow into the pipe when negative pressure is in the pipe. Above the bleeder is fluidly attached at least one check valve to prevent flow of water back to the bleeder.

A water diverting device is used for fitting inside a porous surrounding wall of a vertical drainage pipe which is deeply inserted into the soil for collecting water from the ground level. The water diverting device includes a tubular wall having at least one slit, and a base wall having at least one drainage port. The drainage port is located at a higher level than a lower slit edge of the slit so as to have a lower level of water accumulated for passing through the slit and an upper open end segment of the porous surrounding wall, thereby soaking the soil near the ground level.
