Water System Mapping, Assessment, and Master Planning


The Water Distribution System Plan, (WDSP, the plan), is a comprehensive study of a system’s water source, storage, treatment, and delivery systems. The purpose of a  WDSP is to provide the system with a guide for operating, maintaining, and constructing its water distribution system into the future. The WDSP is not just an exhaustive map which is developed based on information currently available. It is an over all master plan which incorporates a hydraulic analysis with a detailed study of all the sub-systems that support the water system from the source point or points through treatment and storage, to delivery to the customer service representative answering the phone for the utility or municipality.  Ideally, a WDSP are updated every year or two or whenever a large addition, subtraction or maintenance project is completed .

Think Tank Green uses Hydraulic Distribution System modeling software to determine the hydraulic treatment and delivery capacity  from the source point all the way to any customers tap within the system. In this way, it can identify deficiencies in treatment and delivery and help in estimating and ranking capital needs. If necessary, we can even evaluate staffing and administrative operations and include recommendations in the master plan. The preparation of a master plan and associated hydraulic analysis  is critical in understanding the current system and planning for the future.

The purpose of a Water System Master Plan is to:

  • Document water system upgrades, including significant changes in water supply completed prior to any existing Master Plan
  • Estimate future water requirements including potential water system expansion areas
  • Identify deficiencies and recommend water facility improvements that correct deficiencies and provide for growth
  • Update the system’s capital improvement program if one exists (CIP)
  • Help evaluate the system’s existing water rates and system development charges (SDCs)
