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)

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.
