the primary screening chamber 64 (1/11) limited above by the cover of the tank 3 (1/11) has the sides made of a concave part of the tank 25 (1/11) with at its upper edge an inlet pipe for raw water 26 (1/11) collected from the Upper Flow Point (PSE) 26 (1/11) provided with a valve 1 (1/11) from which a pipe leaves deferens 69 (1/11) connected to the inlet tank of relay 76 (1/11) provided with a valve 70 (1/11) which ensures the pretreatment during maintenance of the main tank 25 (1/11 ) is covered inside a filter basket 27 (1/11) housed in a fixed grid 2 (1/11) then partitioned by a screening grid 48 (1/11) with medium mesh 56 (11/11 ) provided with collection baskets for objects and debris 67 (1/11) through which the raw pre-screening water filters is limited below by the settling chamber 28 (1/11).

- The secondary screening chamber 65 (1/11) is limited above by the cover of tank 3 (1/11), with 4 sides 2 to 2 parallel, 2 of which are made of 2 straight and slightly concave parts of the tank 25 (1/11) joined at their internal edges by 2 screening grids, one primary 48 (1/11) and the other secondary 49 (1/11) with fine mesh 58 (11/11) fitted with collection baskets objects and debris 68 (1/11) is limited below by the settling chamber 28 (1/11).

- The prefiltration chamber 66 (1/11), capped by the cover of tank 3 (1/11) is limited at the entrance by a secondary screening grid 49 (1/11) with fine mesh 58 (11 / 11) closed at its two edges by a concave portion of tank 25 (1/11) fitted with two pre-treated and pre-filtered raw water outlet channels, one of which is the main one below covered with a pre-filtration basket 30 (1/11 ) housed in a fixed grid 29 (1/11) which is extended to the outside by an evacuation pipe 32 (1/11) fitted with a valve 31 (1/11) to the main filtration tank 19 ( 1/11) from which starts before, a vas deferens 72 (1/11) provided with a valve 71 (1/11) linked to the relay tank 76 (1/11).

A secondary path above covered with a pre-filtration basket 5 (1/11) housed in a fixed grid 4 (1/11) which is extended to the outside by an evacuation pipe 7 (1/11) fitted with '' a valve 6 (1/11) to the secondary filtration tank 11 (1/11) from which starts before, a deferent pipe 74 (1/11) fitted with a valve 73 (1/11) linked to the relay tank 76 (1/11). Is limited below by the settling chamber 28 (1/11).

The inverted cone-shaped settling chamber 28 (1/11) is limited above by the primary screening chamber 64 (1/11), the secondary screening chamber 65 (1/11) and the pre-filtration chamber 66 ( 1/11) it concentrates and digests pollution. The digested sludge is evacuated below through a discharge pipe 22 (1/11) fitted with a valve 24 (1/11).

If the raw water inlet valve 1 (1/11) in the main tank 25 (1/11) is closed, the relay tank 76 (1/11) is activated by opening the drain valve. relay 70 (1/11) which allows first to empty the main tank 25 (1/11) up to the level of the settling chamber 28 (1/11) then from there to drain below 24 (1/11 ) and then clean all its accessories.

Once the drain valve 24 (1/11) is open, its contents are collected in a bucket 61 (11/11) and poured onto the multifunction table 62 (11/11) covered with a fine mesh grid 58 (11 / 11) the contents are drained and dried, the recovered cloudy water is re-admitted into the device for purification.

Likewise, the pre-filtration baskets (5, 30) (I / II), pre-screening 27 (1/11) and the screening grids (67, 68 ...) (I / II) are emptied of their contained on the multifunction table 62 (11/11) which is drained, dried and sorted, the baskets and the screening screens are then cleaned and repositioned in the main tank 25 (1/11) immediately after its inlet valve 70 (1 / 11) is reopened, conversely that of relay tank 76 (1/11) is closed.

The invention consists of a construction adjoining the wastewater production site from the upper point of raw wastewater inlet 26 (1/11) to the lower point of flow (PIE) (44, 45, 46, 47) (I / Π) it is oriented in the direction of (PIE) following 3 descending levels representative of the 3 main parts of the construction including:

Two intake tanks, one main 25 (1/11) and one relay 76 (1/11),

The filtration (11, 19, 16) (I / II) and storage (36, 38) (I / II) tanks, The evacuation circuits [(10, 47), (12, 46), (35 , 44), (39, 45)] (I / II).

From the upper flow point (PSE) is positioned a main manifold 26 (1/111) which channels the wastewater coming from all internal sources of the site to the main inlet tank 25 (1/11) or from relay 76 (1/11), responsible for their physical and chemical pre-treatment before their admission to the filtration lines (7, 32) (I / II)

Fifteen valves [(1, 70), (73, 6, 71, 31), (20, 41), (9, 13, 43, 23, 24), (78, 80)] (I / II) control the water circulation of the device:

- The inlet valves (1, 70) (I / II),

- The filtration valves (73, 6, 71, 31) (I / II),

- Storage valves (20, 41) (I / II)

- The evacuation valves (9, 13, 43, 23, 24) (I / II) and

The service valves (78, 80) (I / II).

The inlet valves (1, 70) (I / II) act in 2 stages of opening and closing. While the open side ensures water purification, the closed side allows maintenance of either relay 76 (1/11) or main 25 (1/11) tank.

The filtration valves [(73, 6), (71,31)] (I / II) act in pairs of positive or negative sign. While the positive side (73, 6) (I / II) is open ensuring filtration with tank 11 (1/11), the negative side (71,31) (I / II) is closed allowing maintenance of the tanks (16, 19) (I / II).

Each filtration line has a number of tanks proportional to the difference in level between (PSE) and (PIE) the lower it is, the fewer tanks there are, the larger it is, the greater the filtration capacity and the possible number. of tanks.

For a zero or sufficiently low Δ (ΡΕ), the (PIE) is far from the concession and the device is deeply buried in the ground. A possible adaptation is to raise the (PSE) by an elevation from the floor level of the showers and the laundry room.

For a sufficiently large Δ (ΡΕ), the device is at ground level or partially buried. It has an increasing number of tanks with a (PIE) often close.

The filtered water is received in 2 tanks:

The filtered water tank 36 (1/11) and

The filtered disinfected water tank 38 (1/11)

These tanks are made to keep a large quantity of water that they make available thanks to their service tap (78, 80) (I / II) they have an overflow evacuation route (35, 39) (I / II) which continues until (PIE) (44, 45) (I / II).

The last tank of each filtration line (11, 16) (I / II) has an overflow outlet (10, 12) (I / II) which extends to (PIE) (46, 47) (I / II).

The overflow water from the filtration lines (7, 31) (I / II) comes directly from chamber 3 of the inlet tank 66 (1/11) they are fully pretreated but not filtered their flow at the level of the (PIE) constitutes an indicator of the operating state of the filters, their level of performance and / or the state of variability of the initial flows.

The four overflow lines also called evacuation circuits [(10, 47), (12, 46), (35, 44), (39, 45)] (I / II) are each equipped at the outlet with 'a protective filter (82, 83, 84, 85) (I / II) which prevents impurities in the ambient air and crawling or flying animals from entering the device. They are also each equipped with an overflow reader (86, 87, 89, 90) (I / II) which indicates at any time thanks to the bipolar dial 98 (1/11) the internal operating level of the device and the consequent measures to be taken for its regulation.

Drainage conduits often buried in the ground can be observed, protected and analyzed through 2 manholes, including an Internal Operation Control Manhole (RCFI) 88 (1/11) and a Drainage Products Evaluation Manhole (REPE) ) 77 (1/11) which marks the lower limit of the construction.

The (RCFI) 88 (1/11) lets show at the bottom 4 evacuation pipes [(10, 47), (12, 46), (35, 44), (39, 45)] (I / II) surmounted each of a removable device positioned inside the pipe and serving for instant reading of the overflow flow level thanks to its float 94 (1/11) and its bipolar dial 98 (1/11).

The (PIE) is located above the neighboring natural point of flow made up of a gully, a collective drain, a pond, a lake or a stream and is characterized as a zero point of flow (PZE).

The positioning of the (PIE) in relation to the (PZE) is essential; it ensures a continuous flow of overflow thus making it possible to measure the operating state of the system at all times.

The alternating movements of air and water in the vessels and ducts of the device form what we call alveolar respiration (AR). If there is no overflow in a tank it ensures a natural flow of air in the circuit called integral alveolar respiration (RAI) this respiration also exists during the overflow flow but in a partial way it is so called partial alveolar respiration (PAR).

The (RAP) and the (RAI) constitute 2 essential parameters of the functionality of the device:

-The (RAP) on the filtration lines signals either a malfunction of the filtration tanks or an excess raw water intake flow which leads to a (RAI) on the storage lines.

The (RAI) on the filtration lines signals optimum operation of the filtration tanks which leads to a (RAP) on the storage lines.

The multifunctional table 62 (11/11) with multiple bases and interchangeable grids allows all of the cleaning operations of the tanks and their contents to be carried out in an ecological manner.

The objects, materials and faecal sludge collected are drained, dried, sorted and recycled there the sands are washed, calibrated then reintroduced into the tanks using a bucket 61 (11/11), a shovel 60 ( 11/11) and a raclette 59 (11/11).
