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.

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.

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. The biological treatment process includes chemical addition for phosphorus removal to meet permit regulated discharge limits.

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.

DESCRIPTION OF TREATMENT PLANT AND FLOW PATTERN

1. Collection System

The wastewater collection system for this facility is delivered by gravity to four pumping stations which serve the main Housing and Industrial Area, Supply Building Area, Operations Building Area, and the Receiving Building Area, respectively. The wastewater generated at the pumping stations is then delivered to the WWTP.

2. Secondary Treatment During normal operation, the raw wastewater enters the treatment plant at the mechanical bar screen where large solids are removed from the waste. From there, the wastewater is split and flows by gravity to two 81,600 gallon equalization tanks. These tanks maintain a constant rate of flow through the advanced wastewater treatment (tertiary) portion of the plant. The equalization tank pumps send the flow to a splitter box where the wastewater is evenly divided and flows by gravity to three aeration tanks that are provided with mechanical aerators. The effluent then flows to dual clarifiers where the sludge settles to the bottom. The activated sludge is returned to the aeration tanks or wasted to the aerobic digesters.

3. Chemical Treatment The clarified wastewater flows by gravity from the clarifiers to the chemical equalization tanks where aeration provides a blending of the contents and prevents deposition of solids in the basin. A constant rate of flow from the tank provides improved chemical feed control and process reliability through the tertiary (settling, filtration) phase of the plant. A magnetic flow meter is provided on the discharge from the equalization tank to indicate rate of flow.

Soda ash and alum equipment provides for pH adjustment and flocculation, respectively to remove dissolved phosphorus through sludge waste. After passing through the flash mixers and flocculation tanks, the chemically treated wastewater enters the advanced (tertiary) treatment portion of the process.

4. Advanced Treatment From the flocculation tanks, the wastewater flows into the chemical settling tanks where any remaining organic matter settles. The wastewater then overflows into a trough that delivers the wastewater to two dual media filters.

The treated effluent from the filters enters the clearwell where it is pumped to another flow splitter box. A magnetic flow meter on the discharge of the clearwell provides flow rate information. Surface wash and backwash pumps are also provided for backwashing the filters when they become clogged. From the splitter box, the effluent flows through the ultraviolet disinfection unit where exposure to ultraviolet radiation disinfects the wastewater. Post aeration tanks add oxygen before the effluent enters the receiving stream, a branch of the Northwest River.

5. Sludge Handling The extended aeration treatment process results in reduced quantities of sludge to be wasted. Any wasted sludge from the sludge return pump station as well as accumulations from the flocculation and chemical settling tanks are diverted to the aerobic digesters. Following sufficient time for digestion, the sludge is delivered to the sludge dewatering building for pressing and subsequent hauling to a sanitary landfill for disposal. In the event that the filter press is down for maintenance or repair, sludge may be diverted to the drying beds for eventual removal to the landfill.

Weight of dried sludge removed annually:

2015: 50.56 tons 2016: 70.58 tons 2017: 76.36 tons 2018: 64.58 tons

6. SCADA PLC System All of the facilities are automatically controlled by a Wonderware based Supervisory Control and Data Acquisition (SCADA) system consisting of a personal computer (PC) interconnected to a Programmable Logic Controller (PLC). The SCADA system and the PLC initiate operation of pumps, record and totalize flows, control chemical feed rates and initiate backwash of the filter as well as signal alarms and control the main process equipment of the wastewater treatment system. The SCADA system is the "heart" of the wastewater system operation.
