Just some of the accomplishments that GWA has completed since the Consolidated Commission on Utilities (CCU) was created.

Established Apprenticeship program for Water & Wastewater trades.

Established Public/Private partnership for Wastewater system by contracting Veolia.

Completed 60% of the AMR project replacing and upgrading all water meters.

Improved been chronically low water pressure in Barrigada with GWA crews worked from March to July of 2007.

Santa Rita Spring Transmission Line, a $1.5M project to construct a transmission line from the Santa Rita Booster Station to the Santa Rita storage tank and to upgrade the booster station was completed in the summer of 2007. The completed work allows GWA to better manage water levels in the storage tank in order to consistently provide better water pressures to the area.

Agat/Santa Rita Route 5 Transmission Line, a $1.5M project to install a transmission line from Cross Island Road by the Fena Treatment Plant to the Santa Rita Booster Station and Storage Tank. The completed project will provide a back-up water supply for Agat and Santa Rita and allows GWA to reduce its dependency on Navy water purchases. A construction contract is in place and active construction is expected to commence in February 2008.

Hagatna Treatment Plant Rehabilitation, a $10.5M project to complete a comprehensive rehabilitation of the Hagatna Wastewater Treatment Plant, was completed in January 2007. The plant is now in compliance with discharge permits for the first time in over 20 years.

Agana Main Lift Station Upgrade, this $500K pump station project is an extension of the Hagatna Treatment Plant renovation project. The project will conduct structural and electrical improvements and repair grit removal equipment that is important for the continued performance of the treatment plant itself. A contract is in place for the work and active construction will begin upon arrival of pumping equipment necessary to back-up the pump station during construction activities. Work will be completed in summer 2008.

Wastewater Treatment Plant Ocean Outfall, a $17M project to install new ocean outfalls for the Hagatna and Northern Wastewater Treatment plants, that when completed projects will discharge treated wastewater further out and deeper into the ocean while promoting mixing with ocean water. The completed outfalls will prevent treated wastewater from washing back toward the beach. Construction work is underway with both projects are expected to be completed by summer 2008. The Hagatna wastewater treatment plant outfall is 270 FT and the Northern Wastewater Treatment Plant outfall is 140 FT.

Tank Inspection ($500K of 2005 bonds), a project to complete a comprehensive inspection of all water storage tanks and identify needed repairs. A solicitation will be let by June 2008 with a target completion date of December 2008.

Mangilao Tank Replacement, a $1.25M FEMA funded project to replace a water storage reservoir damaged in a previous typhoon, is under contract. Demolition activities for this begin in early March with construction of the new tank to follow within two months.

Laboratory Renovation ($200K of 2005 bond funds), is to complete a design for a renovation and expansion of the GWA main laboratory. The laboratory processes water and wastewater samples to insurance compliance with SDWA and CWA regulations. Future projects will provide for the construction of the lab. A design solicitation which will be let in spring 2008.

Baza Gardens WWTP Facility Plan, a $500K project funded by the 2005 bond to complete a facility plan for the Talofofo Wastewater Treatment Plantd to be replaced with a new facility. The facility plan is a pre-design document that will determine the critical parameters including: location, size and capacity, treatment technologies, treated wastewater disposal options, and design and construction cost estimates. The facility plan will provide a roadmap for the detailed design work to follow. The facility plan is scheduled for completion in March 2008. A request for construction funding will be part of a future bond issuance.

Old Agat Wastewater Collection System, $4.18M EPA SDWA, will replace parts of the collection system in old Agat. The completed project will correct problems in the system that result in collection of storm water and groundwater in the sewer system. It will eliminate wastewater overflows caused by excess storm water entering the system and improve the performance of the Agat Wastewater Treatment plant. The design has been completed and a construction solicitation was let in 2007. Bid prices were significantly higher than anticipated and were rejected. The GWA engineering staff is revising the construction package and will re-solicit in the spring of 2008. Construction is expected to take 12-18 months once a contract is awarded.

Upgrade of Groundwater Chlorination System: This is a $3.5M project that will be jointly funded by USEPA and 2005 bonds. This project will renovate water well stations with an emphasis on chlorination systems and controls. The installation of primary equipment has been completed by GWA. A construction contract has been executed to complete the remainder of the work over the summer of 2008.

Well Electrical Protection: $1M of 2005 bonds. This is an ongoing effort to improve the electrical controls at water well sites around the island. The work to date has been completed by a joint GWA/GPA task force. The result has been less frequent pump and motor failure providing more consistent and reliable water supply. An additional contract to install variable frequency drives at critical wells will be awarded in February. The drives will provide additional electrical protections and will provide better control over pumping rates for management of the aquifer.

Ugum Treatment Plant Rehabilitation: This is a $8.5M project that will renovate the Ugum Treatment plant to add capacity and improve the reliability of the treatment process during the rainy season. The refurbishment will include the conversion of existing conventional surface water plant to a micro-filtration system; replacement of electrical control systems; replacement of finished water pumps; installation of SCADA equipment; and the refurbishment of the backwash waste handling system. A design build project has been awarded and design work is progressing. Construction will take place in 2008.

Sinajana Transmission Line: This is a $7.7M transmission line project. It will construct approximately 24,800-feet of 8, 12, and 24-inch water transmission line between the Chaot and Agana Heights water storage tanks, the connection of 7 existing A-series wells to the transmission line, and chlorination equipment at each of the two storage tanks. The new pipeline will be dedicated transmission line to the storage tanks. The project is being let in 2 phases. The first phase in under construction and will be completed in March. The second phase will be let in the spring of 2008 with a scheduled completion date in early 2009.
