DEFINITIONS AND ACRONYMS

Definitions Equipment, Collateral Encompasses built-in and large substantially affixed equipment/property that is normally acquired and installed as part of a facility project.

Equipment, Installed Encompasses building-type equipment, built-in equipment, and large, substantially affixed equipment/property, and is normally acquired and installed as part of a facility project. Installed equipment is normally required to make a facility useful and operable.

Removing such equipment would impair the usefulness, safety, or environment of the facility or the facility restoration work required after its removal, is substantial.

Equipment, Personal Property

Personal property equipment includes all equipment other than collateral equipment.

Such equipment, when acquired and used in a facility or a test apparatus, can be severed and removed aster erection or installation without substantial loss of value or damage thereto or to the premises where installed.

Facilities Life Cycle A facilities life cycle is divided into four stages, requirements (planning and design), acquisition (construction and acceptance), stewardship (operations, maintenance and repair), and disposal.

Facilities Maintenance Management

The planning, prioritizing, organizing, controlling, reporting, evaluating, and adjusting of facilities maintenance operations to support the CNO/NAVFAC facilities policy and objectives and satisfy customers’ facility needs. Defined by the International Facility Management Association as “the practice of coordinating the physical workplace with the people and work of the organization.”

Integrated Maintenance Plan

IMP is a recurring state-of-the-art, reliability-centered inspection, testing, maintenance and repair program that determines best practices for managing the functions and consequences of failures of facilities equipment and system components. IMP encompasses accepted commercial practices, including reactive, preventive, predictive and proactive maintenance, into one optimal program. The IMP approach gives the Contractor full responsibility to maintain systems and equipment and perform repairs whenever necessary to ensure equipment and systems are operational and remain in a constant state of readiness.

Life-Cycle Costs A form of economic analysis that considers the total cost of owning, operating, and maintaining a building or system over its useful life.

Repair Repair is the restoration of facilities or equipment to such a condition that it may be effectively utilized for its designated purposes by overhaul, reconstruction, or replacement of constituent parts or materials which have deteriorated by action of the elements or usage, and which have not been corrected through maintenance. This term also applies to replacement of the entire unit or system if beyond economical repair. The intent of repair is to have the equipment at normal working condition.

Replacement Replacement, as a distinct work element, is confined to a program of planned replacement of a facility or its components. It may be further limited to major components such as air conditioning compressors, furnaces or hot water heaters. Replacement is performed when the equipment has reached the end of its useful life; when it no longer can perform due to degradation of its internal components and repair is no longer cost effective. Included under the replacement would be the major rebuilding of any component, since rebuilding also restores performance.

Restoration Restoration of real property to such a condition that it can be used for its intended purpose. Includes repair or replacement work to restore facilities damaged by inadequate sustainment, excessive age, natural disaster, fire, accident or other causes.

DEFINITIONS AND ACRONYMS

Sustainment Maintenance and repair activities necessary to keep a typical inventory of facilities in “normal working condition”. Sustainment includes regularly scheduled maintenance as well as cyclical major repairs or replacement of components that occur periodically over the expected service life of the facilities.

SCADA A version of telemetry commonly used in wide-area industrial applications, such as electrical power generation and distribution and water distribution, which includes supervisory control of remote stations as well as data acquisition from those stations over a bidirectional communications link.

WASTEWATER TREATMENT PLANT AND COLLECTION SYSTEM DESCRIPTION AND INVENTORY

Treatment Process

NSA Northwest Annex Wastewater Treatment Plant (WWTP) is an advanced treatment plant utilizing the extended aeration modification of the activated sludge process followed by flocculation, settling, and dual filter media filtration. NSA Northwest Annex wastewater treatment is a biological process and chemical use (polymer) is limited to the sludge hydraulic press only; however, it is expected that new upcoming requirements (July 2014) will mandate the use of a chemical injector (to be implemented within four years of new requirements) at the WWTP mixer/chemical setting tanks to allow the removal of phosphorus. In July 2019, NSA Northwest implemented a Sodium Aluminate and Soda Ash process.

WWTP effluent flows through an ultraviolet disinfection unit and is post-aerated prior to being discharged into the receiving stream. WWTP facilities are automatically controlled by a PLC/SCADA system consisting of an interconnected personal computer (PC). WWTP and system process breakdown is as follows: collection system, secondary and advanced treatment, and sludge handling. The WWTP is designed to remove 97 percent of raw BOD5 and suspended solids based on plant influent concentrations of 240 milligrams per liter. The WWTP is capable of handling a daily flow of 300,000 gallons per day with a peak hydraulic flow rate of 750,000 gallons per day and experiences a current average flow rate of 125,000 gallons per day. The facility has no more capacity for future growth.

Wastewater Treatment Plant

The WWTP is located within a chain link fenced compound and includes the main PLC/SCADA equipment, sewage holding, filtration and treatment equipment in Bldg 240, laboratory equipment in Bldg 439, sludge hydraulic press equipment in Bldg 392, two emergency holding ponds with a capacity of 3.38 million gallons at a depth of 4feet, with liners replaced in 1991, and associated treatment process pumps, valves, and piping.

Wastewater Collection System

The Wastewater Collection System includes 18 packaged type lift stations and pumps, 3 main enclosed type lift stations and pumps, gravity flow sewage piping, and force main sewage piping, and associated alarms.

Refer to the Wastewater Treatment Plant O&M Manual/Operation for additional data detailing the treatment facility.
