Southwest Missouri City

Project Overview

Alliance Water Resources’ contract with this southwest Missouri city began in February 2011. Alliance was immediately tasked with identifying and eliminating the causes of the distinctive sulfur odor at the water treatment plant, identifying and eliminating the cause of hard water scaling, and instituting record keeping to satisfy state and federal regulations.

The City contracted with Alliance for the operations and management of its water and wastewater treatment system. Alliance was charged with operating, repairing and providing preventive maintenance for the City’s water and wastewater treatment plants, including sewer collection and water distribution, reading meters and providing capital improvement planning, technical services and annual state-mandated consumer confidence reports.

The city council brought Alliance on, in part, because of extensive experience operating reverse osmosis water facilities similar to the City’s.

During the negotiation process, the City’s public works employees were unsettled by the prospect of losing their jobs if a contract operator were hired. Once the management contract was in place, Alliance immediately hired and trained the 13 former public works employees who applied to work for the company.

Challenges

System Description
Services Performed
Challenges
  • The City’s water treatment plant lacked maintenance and its water and wastewater system employees lacked adequate training
  • City officials believed that inferior water quality, including taste, smell and scaling was preventing it from attracting new business to the area; business owners complained about the high cost of repairing equipment damaged by substandard grade water
  • The City was in the final stages of a three-year wastewater treatment plant upgrade scheduled for completion in 2011
  • Wastewater pipes throughout the City were in poor condition, and there was a serious inflow and infiltration problem into the sewer collection system
  • The city council was challenged during a down economy with budgeting for future upgrades to its infrastructure to satisfy impending MoDNR and EPA regulations changes
  • City officials were pressing for robust, accurate and regular written reports on the condition of its facilities
Achievements
  • Alliance has determined that some of the City’s ingoing and outgoing water flow meters at the water treatment plant are broken
  • Employees are in the process of cleaning, repairing and replacing spray nozzles in the water treatment odor control system and performing sulfide tests to determine where the plant’s odor is originating
  • Alliance is working with the contractor building the City’s new wastewater treatment plant to ensure its timely completion
  • The staff has implemented a system to regularly gather and record data to satisfy reporting regulations
  • Employees are inspecting equipment to determine needed repairs
  • Employee training to meet OSHA requirements is underway
  • Five large flow meters were replaced at WTP
  • Alliance formed a water quality study group to gain insight on corrosion/scaling in distribution system
  • A five-year capitol improvement plan has been established
  • There has been a 100% odor removal and Alliance has repaired primary and secondary odor scrubbers
  • Alliance implemented a routine water tower inspection every five years
