[summary of the invention]

Goal of the invention: in order to respond national policy, the conserve water resource, the present invention considers the regeneration of the assorted drainings of high-quality such as having a bath, do washing, wash one's face and rinse one's mouth, thereby reaches the purpose of conserve water resource.

Technical scheme: the original building drainage pipe is that each layer washing machine sewer pipe, wash basin sewer pipe, water for bathing sewer pipe pass floor, inserts in the main drain road (10).Native system is set up a gutter (1) in whole washroom, building, and each layer washing machine sewer pipe, wash basin sewer pipe, water for bathing sewer pipe pass floor, inserts wherein, uses for flush toilet.This washroom, whole building water-saving system comprises gutter (1), tank inlet pipe (2), energy-saving toilet water tank, cistern water-discharging pipe (3), valve (4), threeway (6).Valve when using this system (4) is in closed condition.Establish dividing plate in the middle of the water tank, the left side keeps the water purification water inlet, is the tap water storage tank.Foul water tank is half side on the right side, keeps common water tank original device.Establish overflow pipe (5) in the foul water tank, when the water surface reached the outfall height, water entered down one deck by gutter (3).When the water surface reached the overfall gap height, water entered toilet by overflow pipe (5), imported main drain road (10).

Water supply volume is calculated: the automatic washing machine 120L/ cycle; Bathing water: 0.15 ton/time of winter, 0.08 ton/time of summer; The toilet water supply volume accounts for the total consumption about 35% of family.The three-person household water consumption per month is about 10 tons-14 tons.(above data from network and ASSOCIATE STATISTICS mechanism).

It is example with the three-person household: washing machine water consumption per month: 6 times=0.72 ton of 0.12 ton/cycle *.

The water consumption per month of having a bath: winter: 4 times=1.8 tons of 0.15 ton of/time * 3 people *

Summer: 30 times=7.2 tons of 0.08 ton of/time * 3 people *

Consider spring, autumn factor, weighted average: (1.8+7.2)/the 2=4.5 ton

The water consumption per month of estimating to wash one's face and rinse one's mouth is about 0.5 ton.

The water tank moon, inflow was: 4.5 tons+ton=5 tons O.5.

The water tank water consumption per month is: the 10*0.35=3.5 ton, the 14*0.35=4.9 ton is average: 4.2 tons

Be that output 60%-80% calculates according to water supply volume: 5*0.8=4 meets the requirements.

Checking computations: be 3 tons with the kitchen water consumption per month, add up to: the 5+4.2+3=12.2 ton between the 10-14 ton, tallies with the actual situation.

In sum, native system can utilize the draining of mixing of high-qualitys such as washing machine water, bathing water, the water of washing one's face and rinsing one's mouth fully, can save about 4.2 tons in tap water, accounts for total water amount about 1/3rd.

Beneficial effect:

Cost: PVC gutter (from the top layer user to bottom of the building), two of threeways, two of flexible pipes, one on valve, change one in old toilet water tank.

Benefit: 4.2 tons of the every monthly average water savings of each household account for total water amount 1/3rd.
