rainwater harvesting systems are made up of the rainwater storage tank, or rain harvesting tank, the rainwater harvesting system filter and the rainwater harvesting pump or rain harvesting delivery method .Rain harvesting products come from a wide variety of specialists rainwater harvesting system manufacturers combined harvesters specialise in both commercial and domestic harvesting of rainwater .In commercial rainwater harvesting systems the rainwater is stored in a larger GRP rain storage tank, the rain pump delivers the harvested rainwater to the required source .Rainwater harvesting information can be usually sourced from company brochures. Rain water collection can be in standard rain water collection tanks made from GRP or from HDPE .It is important that the rain water collection tank has smooth sides to inhibit algae growth . Most rainwater harvesting companies have ‘how to harvest rainwater’ training classes .The water storage or water storage tank underground or above ground water storage tank is usually for non potable water storage .Rain water is collected from the rainwater gutter and the fallen rainwater is filtered through a rainwater downpipe. Some rainwater filters are actually fitted to the rainwater downpipe and the filtered rainwater is collected in a plastic tank or water butt which is housed nearby. Some water butts are injection moulded and other water butts are blow moulded .This generally means that the waterbutt can be a lot lighter than standard water storage tanks .Some waterbutts have downpipe fitted diverters and filters other water butts have separate filter diverters . Underground rainwater storage tank, also known as underground storage tanks hold the rainwater but you should be mindful not to have an oversized rainwater harvesting tank as the rainwater stored has the potential to go off and smell. Combined harvesters ltd fit commercial rain harvesting systems and commercial rainwater harvesting filters .Suppliers are graf, kingspan, titan, polypipe and raincatcher .Water tanks come in all shapes and sizes but are mostly 2.5m wide, all water tanks are strengthened.

At geotextilemembranes.co.uk we pride ourselves in the ability to supply all woven geotextile membrane along with standard woven geotextiles and geomembranes .These geotextile membrane fabrics come in many weights and clients should be aware that a consideration for geotextile membranes porosity should be made .Terram geotextile membrane and geomembrane is a generic brand as is greenseal, firestone pond liner, epdm liner and epdm pond liner epdm liner is imported and also goes by the name of bitumen membrane, butyl box liner, butyl liner, butyl rubber, butyl pond liner and others.
Woven geotextile such as 606 is the ministry of transport rating and is used for horse manages, horse ménages as a stabilisation fabric before the geomembrane of heat treated fleece membrane is put in place. The non woven geotextile membrane such as terram 1000 or bona rtf membrane is the stabilisation upper layer that allows water to percolate through. Not a weed fabric or weed prevention membrane but a superior non woven geotextile membrane . A geomembrane comes from other suppliers such as rhino or gtex or geotex and has the ability to perform in similar manners. Geomembranes are seam welded to stop seepage in attenuation trenches or infiltration trenches. Purpous welded geotextiles will be classed as protective membranes around the infiltration or attenuation trench when designing a system for sur2 regulations bs8515:2009. Weedex and weed prevention fabrics are generally considered to be hydrophilic or fully porous fabrics. Wovehn membranes are less able to allow water to permeate through and some woven heat treated geotextile membranes allow very little water to permeate through the fleece membrane fabric.. Terram membranes are the industry recognised standard for all types of woven geotextile, woven geomembrane, non woven geotextile and geotex , terram 1000 being the most popular

A soakaway or soakaways drainage design is important for many reasons including; flood, flood defence, flood prevention, stormwater management, sustainable building, sustainable drainage, sustainable construction, Sustainable urban development, Urban hydrology, Wastewater management etc. Sustainable construction, sustainable design and sustainable housing are in the forefront of everyone's minds at the moment and is an important thing to consider when building or renovating any house or garden. Creating a more sustainable, eco friendly house will add to the selling potential. Flood defence, flood prevention and storm water management are certainly a paramount with the extreme flooding we are experiencing at the moment. The design of your rainwater drainage and land drainage is important, to create good flood prevention measures. A good flood prevention measure is a soakaway for rainwater and surface water run off. Construction of a drainage soakaway will require the digging of a drainage ditch. Digging this drainage ditch is not difficult and it the first step after the drainage design for waste water management has been decided. Drainage design will include a range of drainage products, drainage pipes, drainage crates and geotextile membrane being placed in the drainage ditch. You may also require a drainage sump. The drainage design may include permeable paving or rainwater drainage from the driveway. Stormwater management systems come in all shapes and sizes, they can be made to measure or buy as a complete pallet package. Soakaways are an easy stormwater management and prevention solution and a fantastic way of flood defence and waste water management, helping immeasurably towards the creation of sustainable living and sustainable design. Construction of driveway drainage or permeable paving may be helped by a local landscape gardener, who may also assist in digging any drainage ditches or drainage sumps and may be able to offer further advise on rainwater drainage, sewer design and Urban stormwater management. Combined harvesters can also offer the services of our own in house team for such things as drainage construction, installation for a soakaway or drainage solution, digging any drainage ditches and drainage sumps and the laying of permeable paving and driveway drainage. Soakaway flood prevention measures for subsurface drainage, in summary, are an easy drainage design evolving only a small number of drainage products and little constructions design knowledge. Combined harvesters supply a full range of drainage pipes and drainage products, including permeable paving for driveway drainage. We also can provide advise and assistance second to none during and after the drainage design and construction of your stormwater management solution. On request we can discuss with you your options regarding soakaways and information on why rainwater drainage is important for the development of sustainable design and sustainable living. We can offer advise on construction of a ditch, sizes required, construction of drainage sumps and any other information you might require about water flood prevention and Urban hydrology
