Considerations in the Hydraulic Design of Pipelines
The report summarises the findings of pipe reviews which were conducted during the research project
and highlights the following actions which should be considered during the hydraulic design of
pipelines :
• Review and incorporate available recorded hydraulic performance data of pipelines in the region in the design of new infrastructure;
• Include the secondary energy loss associated with the dimensional details of the couplings in the calculation of the energy loss in the pipeline;
• Use the proposed BRM (biofilm resistance model) to calculate a representative roughness for biofouled pipelines;
• Implement the proposed procedure to determine the remaining useful life of pipelines to be able to prioritize the upgrading or replacement of system components; and
• Provide monitoring points for the initial, continuous or intermittent hydraulic assessment of the pipeline.

Pipe Inspection Manual
The New Zealand Pipe Inspection Manual 3rd Edition has been prepared in order to provide:
• An overview of the tasks that can be completed using Closed Circuit Television (CCTV) and how these activities can be used to manage wastewater and stormwater assets.
• A standardised set of codes for recording observations noted during CCTV inspections.
• An outline of good practice procedures for carrying out CCTV inspections and for processing and analysing the information collected.
• Standard Technical Specifications and Model Conditions of Contract for use when engaging CCTV contractors.

Hydraulic Study For The New Cairo Raw Water Pipeline
phase is expected to be completed by the end of 2011. The system consists of one raw water intake pump station (IPS), three booster pump stations (BPS 2, 3, and 4), and multiple parallel 2200-millimeter (mm) and 2600-mm diameter pipelines that run approximately 30 kilometers (km) from the Nile River to the newly constructed New Cairo Potable Water Treatment Plant (WTP). Construction will be completed in eight pump installation phases, with design flows ranging from 6 cubic meters per second (m3/sec) at Phase 1 to an ultimate flow of 48 m3 Because the pumping capacity required for Phases 5-8 is to be supplied by a parallel system of pump stations and pipelines that mirror Phases 1-4 (with identical hydraulics and capacities), the following report is based on analysis of Phases 1-4 only. The ultimate flow rate for Phase 4 is 24 m /sec at Phase 8.
