Essex Rivers Hub

There are many field drains entering the Mardyke in the Arable area in South Ockendon and beyond. These drains allow water to flow off the fields so they don't become water logged, however this water carries silt, phosphate and some pesticides into the river that can cause a variety of problems to the water environment. 

 Silt can causes blockages in some instances and also inpacts on fish and invertebrate populations by smothering fish fry and and invertrbates with live in the river bed. Phosphates can causes increased growth of aquatic plants which causes them to grow out of crontrol reducing oxygen within the water. 

in order to reduce these impacts we aim to work with landowners to examine whether improvements can be made to current methods used for ditch management and field drainage and suggest plausible alternatives where they exist.
