City of Pasco
Butterfield Water Treatment Plant High Service Pump Evaluation
February 2021
Background
The City of Pasco's (City) Butterfield Water Treatment Plant (WTP) uses five high service pumps to
pump treated water into the City's potable water distribution system. High Service Pump No. 1 has
been damaged beyond repair, and an evaluation by Layne of Washington, Inc., (Layne) revealed
significant damage to the impeller believed to be a result of considerable cavitation occurring in the
pump. The cavitation is believed to have been occurring as a result of Pump No. 1 operating at
conditions with significant net positive suction head requirements (NPSHR). Layne has proposed a
new High Service Pump No. 1 impeller with reduced NPSHR that will reduce or eliminate cavitation.
The City has requested RH2 Engineering, Inc., (RH2) to evaluate the old and proposed Pump No. 1
curves and operating conditions to confirm that the proposed Pump No. 1 will operate at favorable
conditions with reduced NPSHR.
Task 1— High Service Pump No. 1 Evaluation
Objective: Evaluate the old Pump No. 1 operating conditions and compare these operating
conditions to the proposed Pump No. 1 curves. Document the ability of the proposed Pump No. 1
to provide flows comparable to the old Pump No. 1 and the NPSHR of the proposed Pump No. 1 at
the anticipated operating conditions.
Approach:
1.1 Review and chart the pump curves of the existing five (5) Butterfield WTP high service pumps.
1.2 Evaluate City -provided pump staging information and identify the Pump No. 1 operating point
for common pump combinations.
1.3 Chart the proposed Pump No. 1 pump, efficiency, and NPSHR curves, and superimpose the
operating points identified in subtask 1.2 for the proposed pump.
1.4 Identify benefits and deficiencies of the proposed Pump No. 1 operating points.
1.5 Document the findings of subtasks 1.1 through 1.4 in a technical memorandum. Provide a draft
technical memorandum to the City for review, and finalize the technical memorandum
following receipt of City comments.
Assumptions:
• RH2 will rely upon the accuracy and completeness of any information, data, and materials
generated or produced by the City or others in relation to this Scope of Work.
