HWE offers a wide variety of services in water, sanitation and environmental engineering and science from the needs identification stage to the elaboration of tender documents, supervision of works and technical assistance. Also, HWE offers services in capacity building through providing training and awareness programmes.

HWE concentrates in its work on the urban areas of Palestine and therefore it has implemented a number of projects with the main Palestinian municipalities such as Nablus, Tulkarem, Ramallah, Salfit, Jericho and many others. The Palestinian rural sector is also important and therefore HWE coordinates activities to serve all the rural areas to have water supply and safe sanitation services.
