The irrigation system is designed for wastewater irrigation on small slopes, ensuring the protection of water resources and the environment from pollution.

Surface irrigation on small slopes is carried out mainly on deep running furrows, which are filled with water to 2/3 of their depth and through the bottom and soaked part of the slopes moisten the soil. This kind of soil moisture is insufficient for crops continuous sowing (cereals, perennial and annual herbs, etc), especially when their root system is not developed. For this reason, a culture of continuous sowing irrigated by flooding on stripes.

Known irrigation system from watering down the slope for wastewater treatment, including pipelines wastewater and clean water, mechanical treatment of wastewater, pond drive, the slope of a plot of the natural biological treatment irrigation blocks, educated longitudinal ridges passable for cellcolonies hollows also passable for agricultural machinery profile [1].

However, long experience watering of crops continuous sowing the overlap of the bands in the irrigated areas having a slope less than 0,007 showed that the irrigation norm in these conditions increases dramatically and reaches up to 2000 m3/ha and more, which leads to a significant loss of scarce irrigation water as well as soil salinization and waterlogging of irrigated lands [2].

The purpose of the invention: reducing irrigation rates in 2...3 times when watering crops continuous planting in the irrigated areas with slopes less than 0,007; providing a more uniform wetting of the root system narrow-row crops especially in the early stages of their development; savings of scarce irrigation water, which is achieved by applying flooded irrigation furrows.

The solution of this problem is the fact that irrigation system with wastewater irrigation on small slopes constructed irrigation tiers natural biological purification formed permanent sprinklers [3] reinforced irrigation tubes and flowing flooded irrigation furrows [4]. Irrigation tube diameter 0,04 0,06...m are installed in the dam fill every of 0.6...0.9 m depending on the slope surface irrigation tier. Flowing flooded irrigation furrows DL,25 m, depth from 0.10 to 0.12 m wide row spacing of 0.60 m, and in the irrigated plot with gradients i0,004 flow irrigation furrows made by the bottom width of from 0.23 to 0.25 m, width at the top from 0.33 to 0.35 m, a depth of from 0.09 to 0.11 m wide row spacing of 0.90 m, to ensure excess horizon irrigation jet over the crest of a furrow in the range of 0.02 to 0.03 m

In Fig.1 shows an irrigation system with wastewater irrigation on small slopes, Fig.2 - section a-a in Fig.1; Fig.3 - section b-B in Fig.1; Fig.4 is a longitudinal section of the sprinkler with its hydraulic parameters.

Irrigation system with wastewater irrigation on small slopes includes the lead pipe wastewater 1, the mechanical construction of wastewater treatment 2, the supply line of the pure water 3, two-pond-drive 4 diluted wastewater district distribution channel 5, reinforced outlets, sprinkler 6, reinforced irrigation tubes 16, irrigation tier 7, flooded irrigation furrows 8, column 9, enclosing the roller 10, the backing pad 11, enclosing the roller 12 to the accumulation of storm water flowing from the surface irrigation system. On the backup site has an automated pump is istemi is the Nagorno ditch 15 to protect the system from storm water, flowing from the above catchment area.

The system works as follows.

Waste water inlet pipe 1 goes into the construction of the mechanical treatment 2 and later in two-pond-drive 4, where with the help of the inlet pipe 3 is diluted with clean water at a ratio of 1:3. Diluted waste water district distribution channel 5 through the outlet serves to fill 6 and then through the irrigation tube 16 in flooded irrigation furrows 8, cut into irrigation tier 7.

For irrigation of agricultural crops continuous planting on irrigated tier 7 with slopes in the range from 0.004 to 0.007 flow irrigation furrows made by the bottom width of from 0.13 to 0.15 m, width at the top from 0.23 to 0.25 m depth from 0.10 to 0.12 m wide row spacing of 0.60 m, and in the irrigated plot with gradients i0,004 flow irrigation furrows made by the bottom width of from 0.23 to 0.25 m, width at the top from 0.33 to 0.35 m, a depth of from 0.09 to 0.11 m wide row spacing of 0.90 m, to ensure excess horizon irrigation jet over the crest of a furrow in the range of 0.02 to 0.03 m

When making a request adopted the following conventions:

Qb- irrigation consumption produced in the irrigation furrow, >/(m)

where bB. cf- the average width of the grooves (in the plane problem), m;

bitem Cis the calculated width of the front irrigation streams (inter-row spacing), m;

Hbthe depth of irrigation water jets in the groove defined by the graph of the limit values of specific consumption [5], which is developed according to the results of many years of experience crop is irrigated continuous planting, m;

tb- the desired depth of irrigation furrows, m;

lp. I- the length of the furrow (irrigation tier), m;

Vb- speed jet irrigation in the groove defined by the formula

Vb=qb/Nbm/s,

Z - exceeds horizon irrigation jet over the crest of irrigation furrows, defined by the formula

Z=Nb-tbm

m - irrigation depth, m3/ha;

i is the slope of irrigated land.

Calculations show that reducing irrigation rates is due to the increase in specific consumption and, accordingly, the hydraulic gradient and flow velocity jet irrigation in flooded irrigation furrow. So, for example, on irrigated land with slopes in the range from 0.004 to 0.007 in irrigated flow Qb=0,002 m3/s produced in the furrow with a bottom width of from 0.13 to 0.15 m, width at the top from 0.23 to 0.25 m depth from 0.10 to 0.12 m, the specific consumption of Borri watering of the bands) to Vb=0,072 m/s, and irrigation rate would reduce to m=463 m3/ha, versus m=926 m3/ha under irrigation by flooding on stripes, i.e. 2 times. And in the irrigated plot with gradients i0,004 when irrigation flow rate Qb=0,002 m3/s produced in the furrow with a bottom width of from 0.23 to 0.25 m, width at the top from 0.33 to 0.35 m, a depth of from 0.09 to 0.11 m, the specific consumption of the furrow is qb=0,0067 m3(m), stream velocity V=0,053 m/s and irrigating, when it is reduced to m=418 m3/ha, versus m=1181 m3/ha under irrigation by flooding on stripes.

The use of this system allows to reduce irrigation norm in 2...3 times when watering crops continuous planting in the irrigated areas with slopes less than 0,007, resulting wastewater is localized within the active layer of the soil and subsequently spent only on evaporation and transpiration cultivated plants; to provide a more uniform wetting of the root system narrow-row crops, especially in the initial stage of their development; to conserve scarce irrigation water; to improve the environmental safety of the environment.
