How deep is a reed bed?
A new reedbed should aim to provide around 25-30% open pools, 40-50% wet reed, 15-25% dryer reed and 5% scrub. Wet reed should be within 30m of a pool, or ditch connected to a pool, and have a water depth of up to 1m but a minimum spring water depth of 20-40 cm.
How many reeds do I need for a reed bed?
Typical sizes of reed beds are 1m2/pe, so they are more suitable for small, rural works. It is advised to plant 4 reeds/m2 . The most popular reed used is the common reed ( Phragmites australis) although other suitable varieties exist.
Do reed beds smell?
Reed beds do not smell — the water is continuously flowing and being cleaned by having the ammonia removed, so no smell.
Do reed beds work?
They are highly effective when properly designed and can be used in combination with ponds and wetlands to produce near river quality water. Vertical flow reed-beds are more effective at nitrifying effluents, converting ammonia into nitrates and nitrites, than most package sewage treatment plants.
Do reeds need a lot of water?
At the stage of reed rapid growth (at the end of June and begin of July to the end of August), reeds require more water to support growth, so surface water depth could be increased up to 15cm. During this period, precipitation in this region is abundant, so water may be discharged to maintain reed growth.
How do you maintain a reed bed?

Artificially constructed reed beds can be used to accumulate suspended particles and associated heavy metals or to treat small quantities of partially treated sewage effluent .’
How much does it cost to create a reedbed?

What is a horizontal flow reed bed unit?
MTM can undertake the installation of horizontal flow reed bed units that are designed to act as a final tertiary treatment of effluent from a domestic sewage treatment plant. These units are sometimes required where the Environment Agency require an additional treatment level to that already produced by a treatment plant.
What is the purpose of the reedbed project?
It will help create new areas of reedbed priority habitat on land that is currently of low wildlife value. If successful it will generate open reed-dominated vegetation on waterlogged ground, interspersed with open water features along ditch lines and pond areas sustained all year round.
