The Technical Services Section is responsible for the following tasks:

 

 

  • Engineering support for operations and maintenance
  • Capital Improvements Program (CIP) scope and coordination
  • Chemicals
  • Biosolids
  • Library
  • Infrastructure Design Manual (IDM)
  • Odor investigation

Capital Improvement Program  (CIP) support involves tasks such as coordination of project scopes, balancing and allocating funds, participating in consulting engineer selection, attending monthly project meetings, reviewing preliminary engineering reports, participating in technical review committee meetings, and reviewing project manuals. This effort also involves participating in construction progress meetings and completion inspections, as well as coordination with several internal and external organizations. Support includes collection system, lift station, and plant rehabilitation and improvement projects. Annual project design and construction expenditures currently total almost $200 million per year.

Technical Services is responsible for the Branch’s chemical supply contracts, as well as service contracts such as residuals transportation.

Continual improvement involves identifying non-conformances, performing root cause analyses, developing corrective/preventive actions, establishing annual goals and objectives, and monitoring progress. Program management also involves participating in alternate technology evaluation, long-term planning, review of new system designs, development of design guidelines for existing systems, and development of Standard Operating Procedures. Current section programs include: odor control, biosolids, and process unit cleaning and evaluation. These programs are funded through the Branch’s annual CIP and Operations & Maintenance (O&M) budgets.

The odor control program is charged with managing 12 carbon/bioscrubber air treatment units and 26 chemical feed stations. This program is also charged with identifying odor sources and implementing control measures.

The biosolids program is charged with managing biosolids production at 13 “preparer plants,” waste sludge transfer between the remaining 27 plants (via pumping and truck), product marketing, and product transportation and beneficial end use/land application (or landfill disposal as needed). The Branch’s biosolids management program’s Sims Bayou System has achieved Bronze-Level recognition from the National Biosolids Partnership NBP (similar to ISOs 14001 EMS process). This and the entire system are working toward Gold-Level NBP certification. See National Biosolids Partnership (NBP) at  http://www.wef.org/biosolids/.

The process unit cleaning and evaluation program is charged with removing, transporting, and disposing of solids and other debris that has accumulated in plant vessels and lift station wet wells, thereby limiting capacity and equipment operations and maintenance efforts. This program is also charged with evaluating the condition of cleaned units and recommending rehabilitation and/or improvements.
