As with all home improvement projects, there are a number of factors that can affect the total price you pay for installing a drainage system in your garden. Laying a land drain, or French drain is the easiest method of dealing with surplus water in your garden. Drainpipe discharge: The discharge end of your drainpipe can be connected to pop up yard drain emitter that sits flush to the lawn when no water is flowing.Drainpipe inlet: Position the inlet catch basin at the low spot of your soggy area. The grate will sit flush to the lawn for easy mowing. A soakaway is a big hole that is dug into the ground and filled with coarse materials such as stone or rubble. This system allows the water to easily filter down into the ground and soak away. Drainage pumps activate automatically when the water reaches a certain level (using a flotation device much like the one in the cistern of your toilet). A standard dirty water pump will shaft 160L of water per minute which is around 1.5 baths. If only bath taps could fill that fast!

In some parts of England, connecting a drainage system to sewers or storm drains is forbidden, so always make sure to consult your local authorities first to avoid a fine. It should also be noted that drainage work has to be done from late summer to early winter when the soil is usually dry. Simple ditches In terms of how deep the trench for a land drain should be, it should be deep enough to ensure the correct fall from each land drain to the soakaway, but you should also ensure that you have around 300mm to fill over the top of the pipe. This will allow for planting flowers, shrubs, turf and the similar. A sketch of standing water in the yard, will help you decide which of the following strategies is best for your situation. For example, if you simply have no way to drain water from a low spot to another location, your best option may be to build a rain garden or dry well.Drainage systems are typically installed near house foundations with only gravel covering the drain. Drains are placed in the basement, crawl space, or exterior of the home and are either deep or shallow, which drastically affects the cost.

The Geo Textile Fabric will also stop, or at least dissuade, any local roots seeking out a greater water source. A root system can clog or even break a land drain system quite easily. Geo Textile fabric is a polypropylene mat used to suppress weeds and control soil erosion while allowing the controlled passage of water and air.Hire a plumber to perform a drain camera inspection. A camera test provides a detailed evaluation of any drainage problems.

Standard homeowner’s insurance policies do not cover damage from flooding. Most policies only cover water damage from internal sources and not exterior groundwater. How Deep Should a drainage system be?For 80mm land drain the trench width would be 380mm (2 x 150mm + 80mm pipe) and height 630mm (100mm base + 80mm pipe + 300mm drainage layer + 150mm top soil). Because the pipes are perforated, water will get inside from every angle and not just from the lowest part of your garden. That way it will be more easily distributed. Important to remember: the holes need to point down. Otherwise, the water would need to fill the entire ditch before it has a chance to reach the holes. The photo is just an example to illustrate this type of drainage and should not be followed without initial preparations and research. A word of caution on this method, there are a number of things which can render this drainage solution ineffective. To make sure it functions properly and drains the area you will need to make sure the soakaway area can hold enough water and the french drains direct the water downhill.

It’s very likely that you will recognise a soggy garden when you see one. Some of the symptoms include multiple puddles caused by rain that have trouble draining, squelching sounds upon stepping on the soil, reed or similar plants growing in the lawn, and the presence of moss. 10 factors that can lead to poor drainageThe key to designing and installing a drainage system in a lawn is to remember that the water must be able to travel from the surface to the drain, which is installed under the lawn. Help your grass to recover from winter waterloggingand grow a more extensive and resilient root system by applying lawn feed in spring The size of your lawn (or the area you would like to be drained) affects the size of pipe you will need. Choosing the right size is a delicate balance; too small a diameter and the drainage problem won't be fixed; too large and grass won't have enough water to grow. Laying a smaller diameter in a herringbone layout is much more effective than just switching to a larger diameter.
