1.0 GENERAL INFORMATION

1.1 Purpose

The Anchorage Water and Wastewater Utility (AWWU) is soliciting proposals from

qualified firms to render professional services for an updated Facility Plan for the

Girdwood Wastewater Treatment Facility (GWWTF). The anticipated period of

performance is six months from Notice to Proceed.

1.2 Background

The GWWTF is a tertiary (three-stage) wastewater treatment facility that operates under

secondary treatment standards set forth in the National Pollutant Discharge Elimination

System (NPDES) permit. The NPDES permit limits the loading of total suspended solids

(TSS), biochemical oxygen demand (BOD), and fecal coliforms to the Glacier Creek

outfall.

The facility receives wastewater from the Girdwood Community and incorporates grit

removal, fine screening, activated sludge, secondary clarification, mixed media filtration,

and chlorine disinfection. The Girdwood wastewater influent is unique in that it is low

temperature, dilute, low strength, and is believed to contain large amounts of poor-

settling glacial silt. The flows are also highly variable due to high levels of inflow and

infiltration (I/I) and the transient/recreational nature of the community.

The existing facility was originally constructed in 1978 with a design capacity of 0.85

million gallons per day (mgd) and a peak hourly capacity of 2.0 mgd. The NPDES permit

currently limits the capacity to 0.68 mgd. The facility underwent a major upgrade in 1997-

1998 that included a new administration area, removal of the original biotowers, and

modifications to the solids thickening process. Other minor upgrades have been

conducted including a 2004 upgrade to the influent pump station. AWWU has conducted

two membrane bioreactor (MBR) pilot studies but has concerns regarding the use of this

technology in this location.

The focus of this project will be to complete an updated Facility Plan to outline a set of

recommended improvements for AWWU to include in its Capital Improvement Plan (CIP).

These recommendations will focus on maintaining plant functionality, improving

efficiencies, and accommodating anticipated increased future demands. Key

components to be addressed in the Facility Plan work effort are:

• Evaluate treatment capacity options and process options in which to meet a

future permit, flows, and loadings.

• Evaluate options for short-term improvements.

• Evaluate options based on assumed limitations of the new Alaska Pollutant

Discharge Elimination System (APDES) permit, which may include a lower

ammonia standard.
