Designing a Water Transmission Main for a New Residential Development in Thermal California

What is the diameter of the pipeline needed to service the new residential development in Thermal, California? To determine the diameter of the water transmission main for the new residential development in Thermal, California, we need to consider the maximum velocity criteria and the unit headloss criteria as specified by the Western Municipal Water District (WMWD). However, without access to the specific design criteria provided by WMWD on the Blackboard, it is not possible to provide an accurate diameter size. The design criteria may include factors such as desired maximum velocity, allowable headloss, and system requirements.

Factors Influencing Pipeline Diameter Selection

Maximum Velocity Criteria: Sizing the pipeline to meet the maximum velocity criteria is crucial to ensure efficient water flow without excessive turbulence or pressure losses. The selected pipe diameter should facilitate the flow of water within the prescribed velocity limits set by WMWD.

Unit Headloss Criteria: Another important consideration in determining the pipeline diameter is to meet the unit headloss criteria using the Hazen-Williams equation, which takes into account factors such as pipe material, length, diameter, and flow rate. The goal is to minimize headloss while maintaining adequate water pressure throughout the system.

Without specific details on the District's performance criteria for the MD+FF scenario, it is challenging to provide an exact pipeline diameter. It is recommended to refer to the guidelines provided by WMWD for the optimum size that meets the performance standards for the new residential development in Thermal, California.
