In cooperation with Technical Engineering Consulting Company-TECC, Lotti, as leader of the JV Lotti/VIA & AI Engineering S.r.I , has been awarded the following service contracts with the Palestinian Water Authority-PWA on December 22nd 2015, in the framework of the Project Implementation Consultant (PIC) for the Associated Works to Gaza Desalination Plant – WB (IDA) Financing:

  • Design, Tender Documents and Assistance during Tendering of water supply and distribution system in Gaza strip, for a duration of 18 months, and
  • Construction Supervision of the above mentioned works, for a duration of 36 months.

The specific objectives of this project are:

  • To blend the desalinated water with groundwater by construction of storage and blending reservoirs in such way that the resulting overall water quality in all of Gaza complies with WHO and Palestinian drinking water standards.
  • To design and construct a transmission system i.e. the north – south carrier and the necessary distribution system with sufficient hydraulic capacity to transport this water to the end consumers, ensuring a quality service level.
  • To put operation and maintenance of the new system on a sustainable track, by determining the costs of operation and maintenance in order to estimate a transparent subsidy regime for the initial years of operation.
  • Provide technical assistance to the CMWU and Municipal Water Departments in technical and commercial operation of their existing and the newly constructed facilities.
  • To develop a NRW reduction plan and an Energy management plan.
  • To coordinate with CMWU’s separate efforts reduce non-revenue water
  • To coordinate with CMWU’s separate efforts to quantify the socio-economic impacts of utility bills on Gaza households.
  • To plan the power supply system needed to operate it’s the Associated Works based on the feasible alternative to be investigated.

The main Project features are the following:

  • Population of Gaza strip: 1.7 million inhabitants.
  • Water supplied for domestic use in Gaza Strip: 88,466 MCM in 2014.
  • Project area: 365 square kilometers.
  • Construction of about 37 Kilometers of water distribution system.
  • Replacement of about 21 kilometers of old and undersized water pipes.
  • Construction of North South Carrier consisting of about 40.7 Kilometers of pipeline with diameter ranging from 200mm up to 1200 mm.
  • Construction of North loop consisting of about 16.2 Kilometers of pipeline with diameter ranging from 200 mm up to 1000 mm.
  • Construction of Middle loop consisting of about 11 Kilometers of pipeline with diameter ranging from 200mm up to 600 mm.
  • Construction of South loop consisting of about 25.2 Kilometers of pipeline with diameter ranging from 200mm up to 800 mm.
  • Construction of about 12 pumping stations.
  • Construction of 5 main booster stations along the carrier.
  • Construction of blending water tanks for a total capacity of about 200,000 m³.
