Sewerage rain : the purpose and device options

Rainwater drainage: a variant of the first open (lazy)

1. easiest in terms of effort and financial cost way to get rid of your site from the storm drains.Please note that in your building drainage systems such rainwater scheme will not have any relationship.If the terrain allows, the livnevki can work effectively even on small slopes without special boxes, trays and other costly nonsense.Just derive drains in diverting ditches, and they, in turn, to the nearest ravine or creek.
2. option, of course, exaggerated, but the principle of action and rainwater drainage device for private homeownership describes completely.Under this scheme initially operate all such urban engineering networks, calculated according to SNIP 2.04.03-85, which still has not been canceled.The calculation of the estimated volumes of storm water, pollution and the quality of this document are invited to assess empirically.Please be assured that even without long-term and repetitive processing records self-recording rain gauges, see. SNIP p.2.12 rainwater drainage, determine what the rain in your region happened, you can.

Sewerage rain gated: luck is not all

not lucky in the sense that the area is flat as a pancake, and fills it permanently (climate such).It is necessary to invest in a solid pipe stormwater drainage system.So, first we think about the tubes and how to calculate their diameter.We think long, since intra-household rainwater drainage standardized size of 150 mm (in the absence of siltation).In practice, polypropylene pipe with a diameter of 10 cm is able to ensure the functioning of a rain drain system of a private house for 50 years, if not to break mechanically.

rules laying closed rainwater drainage:

• pipe inclination angle is close to the drainage collectors, ie,within 1 mm per linear meter;
• from freezing and deformation tube assembly must protect the pillow (a mixture of gravel and sand) with a thickness of 7-10 cm;
• filtering rainwater downpipe outlet in the sump is desirable but not required;On the one hand you protect your communications from large debris (leaves, insects, sparrows), with the arc - increased hydraulic resistance drain;
• drainage well livnevki must be available for regular inspection and cleaning, as well as the output collector output.

What not to do when mixed scheme

most frequent case, when really want to unite all into one holiday's sewer system and collectors to issue in collective net tears.Do not turn out as such work on drainage pipelines completely different principle, and connect the drain rainwater for household sanitation can afford only a brave man.

Rainwater drainage (livnevki) in a mixed version is a combination of the two previous cases:

• runoff does not have direct access to the drives, but just into the upper aquifers;explains, the snow melts, the land of leaves, the rain has passed, all dried up;
• gutters home bred in the pipeline, padded to the nearest collector (gutter, brook, river);
• plastic combination of open trenches with buried pipe on the non-pressure parts of the pin makes practical for the audit.

One problem, there is such a simple excretory duct, which is connected to rainwater drainage, septic tank close to home in the hope that clears everything as necessarily break out rain.Pressure autonomous sewerage opportunities for private homes are not limitless.Watch as sinks Italy or Hungary in the storm drains.Why do you need such a problem?
