The station of waste water purification to Al-Bireh City

The municipality carried out many vital projects in the city but the most important one is the purification station of waste water because of its importance for the city and the surrounding areas, and the need for such a station.
The station is an example of the technical development which appears in the network of sewerage, and the sewerage network is considered the most integrated and up to date project in Palestine.
The station was implemented through the sewerage network by the engineering department I the municipality with Palestinian hands and purely Palestinian effort and modern techniques. The project aims to serve the citizens, so it is their responsibility to cooperate in maintaining it and keep paying the fees that assure the continuity of the project.
After 29 months of construction the first flow of water flown to the purification station in the city on 15 May 2000, the population the station serves is 50000. the sewerage network was first started in 1958, 60% of the contaminations are connected to the network. The waste water arrives to the station by two pipelines.
The waste water comes from : houses, stores and factories. The house waste water looks like clouds, grey with yellow coloring, contains organic substances and dangerous materials, these organic substances are sulfuric protein and carbohydrates, that gives a very bad smell, this water consists of 2/3 organic substances and 1/3 non-organic substances.

The treatment of waste water go into two stages: physical purification and biological purification, in addition to purification by ultraviolet rays. Non-organic substances are not purified biologically and can cause damage to the network, so to prevent that first treatment is used: two nets with cylindrical chains orbit with a board that has teeth 15mm width which get rid of the large waste by an automatic hock, then the waste reaches to the solid waste place, then it is ventilated, the big parts of sand etc.. must be get rid of.
The project is an example to the out world and is the first in Palestine, it cost 35 DM.
Operating the station costs a lot of money because it needs workers, maintenance and transportation, and this should be covered by the fees, these fees should encourage people to use water economically, for example, rain water should be used in cleaning and washing up in addition to irrigation.
