BurMAN 

Beheira Water & Sanitary Drainage Company. (BWADC) in co-operation with Amsterdam Water Supply (AWS) and Netherlands Management Co-operation Program is considered to be one of the pioneering companies in Egypt & Arab World in the field of applying a new technology to remove Iron and Manganese from underground water with high quality and little costs.. Currently, BWADC experience in the field of removing iron & manganese from underground water is transferred to El Gharby and El Monofya Water Companies.

About Burman:

Burman is a simple system with little costs to decrease the high level of Iron & manganese in ground water wells. The costs of this system never exceed 10% of the traditional ways of removing iron and manganese. It has been to name this method with BURMAN the abbreviation of (Beheira Underground Removal of Manganese) • المياه الجوفية مصدر دائم وآمن لمياه الشرب.

Problems Related to Iron & Manganese Existence in Drinking Water:

• Water distribution networks clogging.
• Additional sedimentations resulted from water chlorination.
• Stains in clothes during its wash.
• Change in water taste.
• Some times water is colored with organic substances.

Burman Phases:

• Abstraction (Well No. 1)
• Aeration.
• Infiltration. (Well No.2)
• Abstraction. (Well No.2)

Burman Advantages:

• Reduce  Iron & Manganese high concentration in water.
• There is no need to add chemical substances.
• It is possible to treat two wells by one aerator.
• It is easy to re-operate the well being stopped unlike the traditional methods.
• No direct sludge or sediments
• Construction costs are  Low.
• There is no need to large areas for construction.
• It is easy to re-operate the well after short stop periods.
 

Burman Disadvantages:

• Interrupted Production.
• Needs large number of wells.
• Needs direct supervision and control.
•  Wells clogging.

Co-operation with International and Local Directions:

• Local co-operation represented in (RIGWA).
• International co-operation represented in Netherlands Management Co-operation Program (NMCP) and Amsterdam Water Supply (AWS).

Co-operation Results:

• Provide save ground water with high quality.
• Establish a comprehensive database which includes the technical and hydrological data for each well.
• Follow the modern standards in wells design and execution.
• Increase boreholes radius and gravel back size around screens to improve water quality.
• Use centralizers around wells casing and screens to guarantee its centralization and proper distribution of the gravel pack around the screen.
• Protect wells heads through making a concrete block around the head.
• Put 1 inch screen pipes beside the screen and casing to be used as observation wells to determine clogging place.
• There is no need for sand trap to avoid bacteria growth and well water pollution.
• Use clay or betonies (backfilling) instead of grouting to isolate the well from the surrounding area.
