Water supply in small communities - Lenntech

Small communities often find it difficult to obtain the capital to construct improved water supplies. Usually the central or provincial government organize and finance multi-communities programs and the fund may be partly revolving, using repayments or earlier loans. The communities candidates for a loan or a grant, or a combination of both, are asked to submit a pre-proposal to the program. Communities are not homogeneous entities, they often consist in the middle classes and the poor, marginalized groups. …See more on lenntech.comsp.info HigH pressure water jetting in tHe oil and gas industrycleaning of tanks is the WOMA® TankMaster.
