    Surface flow is formed by rain and melt waters as well as the water after street irrigation and cleaning. Herewith the rain and melt water sediments in cities form over 2 mm flow because there are large size waterproof coatings (yard, street carriageways coatings, house roofing).


    This method is based on SNiP 2.04.03-85

    Surface flow is formed by rain and melt waters as well as the water after street irrigation and cleaning. Herewith the rain and melt water sediments in cities form over 2 mm flow because there are large size waterproof coatings (yard, street carriageways coatings, house roofing).

    Hydraulic design of drainage system should be performed separately for each plot and area, such designs should best be carried out by the drainage and sewage system design specialists. Gidrolica® surface drainage systems are intended for water collection and expulsion from paving surfaces as well as of building and structure basements. Our company specialists can give You the recommendations on selection of Gidrolica® drainage systems.

    Let’s consider one of the simplified design variants. In order to make a proper choice of drainage gutter it is necessary to calculate the amount of precipitations falling on the nominal area. Q l/s water flow from the area is calculated as follows:

    Q = q20 × F × ϕ

    where:
    q20 – precipitation rate (l/sec) per Ha (Ha = 10 000 2);
    F – nominal area of flow in m2;
    ϕ – coating surface saturation coefficient;

    Example:
    It is necessary to select Gidrolica® drainage gutter
    Type of coating (ϕ): asphalt – 0,95 (see Surface flow coefficient table).
    Precipitation rate (q20) –Moscow region – 80 (l/sec) per Ha (see Precipitation rate table).

    • Area – F = 20×30/10000 = 0,06 (Ha)
    • Load class according to EN1433 – C250

    Rainfall

    Region q20
    Moscow 80
    Krasnodar 100
    Nizhniy Novgorod 90
    Samara 70
    Soratovv 70
    Volgograd 60
    Rostov-on-Don 90
    Sankt-Petersburg 60
    Kazan 80

    Flow surface coefficient

    Surface type Coefficient ϕ
    Roofing 1
    Asphalt concrete pavement 0,95
    Cement concrete pavement 0,85
    Macadam 0,25 — 0,6
    Gravel pavement 0,15 — 0,3
    Grass area depending on soil 0,05 — 0,35

    By putting the data we have into the formula, we can obtain the precipitation amount in this region which should be collected.

    Q = 80 × 0,06 × 0,95 = 4,56 (l/sec)

    According to the value obtained, Q (flow capacity) we select the drainage gutter according to the catalogue, in accordance with the load class. In our case gutters DN 100, cl. С250 (see General characteristics of gutters) suit.

    General characteristics of gutters

    Art. Load class Name DN, мм Length, mm L Width, mm C Height, mm H Вес, kg Проходное сечение, см2 Channel throughput capability, l/sec
    Slope 0,5%
    801 A, B, C Drainage channel LV-10.14,5.12 — plastic DN 100 1000 145 120 1,4 93,3 5,12
    406 A, B, C Drainage channel LV-10.16.18,2 — concrete DN 100 1000 160 182 36 136 5,2
    903 A, B, C Drainage channel LV-10.14.13 — poly-concrete DN 100 1000 140 125 14 92,1 5,01
    700 A, B, C Drainage channel LV-10.14.13 — poly-sand DN 100 1000 140 130 12,8 102 5,69


    For the effective water outflow to sewage systems it is necessary to take into account the flow capacity of pipes (see Flow capacity of pipes at different slopes, l/sec).

    Type of basement for pipes should be set depending on the bearing capacity of soils and loads (see SNiP 2.04.03-85)

    Flow capacity of pipes at different slopes, l/sec

    pipe diameter, mm Slope
    0,05 0,1 0,15 0,2 0,3 0,5 1
    110 4,37 6,19 7,58 8,75 10,71 13,83 19,56
    160 9,72 13,8 16,84 19,44 23,81 30,74 43,5
    200 16,92 24,0 29,39 33,94 41,57 53,66 75,9
