Guyana Water Incorporated

Inter - American Development Bank

The Government of Guyana clearly recognises the links between water, sanitation and poverty, and with the support from institutions such as the IADB and The World Bank; embarked on a reform programme to improve water sanitation services across Guyana as part of the national Poverty Reduction Strategy.

Inter-American Development Bank (IDB)


The Inter-American Development Bank (IDB) funded Georgetown Water Supply and Sewerage Programme II is a continuation of the Remedial Maintenance Project that was funded by the IDB in a loan contract signed in 1996. The current loan contract was signed on June 14, 2000, and the implementing agency at that time was the Georgetown Sewerage and Water Commissioners (GS&WC). The latter was merged with the Guyana Water Authority (GUYWA) on May 30, 2002, to form the Guyana Water Inc. (GWI). GWI is now entrusted with the responsibility for implementing the loan.

The Programme was intended to be financed with a loan totaling US$30 million, of which 90% is contributed by the IDB and the remaining 10% is contributed by the Government of Guyana. The Programme was scheduled for implementation over a 5-year period that commenced in March 2005.

As a consequence of the IDB Debt Relief Initiative, the Government of Guyana has benefited from a debt write-off of US$356.4 million. As part of this debt relief package, the GOG and the Bank have agreed to a cancellation of US$35 million from the active portfolio targeting problem loans and loan components related to project activities that can be carried out with reduced or alternative financing. The GOG and the Bank agreed to the cancellation of the total amount from eight (8) different operations. This included cancellation of US12.239 million from the Georgetown Water Supply and Sewerage Programme II. As a result of this cancellation, the GOG and the Bank agreed to restructure the project in order to adapt it to the new context while maintaining its original objective. The revised Programme II will now total $16.4 million of which $14.76 will be contributed by the IDB and $1.64 million by the Government of Guyana. The revised Programme II is scheduled to be completed in 2010.


Construction of the Iron Removal Plant at Central Ruimveldt and Sophia

These two installations are already equipped with wells, storage tanks and booster pump stations. The work to be undertaken will include pumping the water from the existing wells to aeration towers where the water comes into contact with the oxygen in the air. The water then flows by gravity to oxidation tanks where the iron precipitate is removed. Any iron remaining in the water is removed as the water passes through the filters. From the filters, the water goes into the existing storage tank. The water is disinfected with chlorine as it is pumped into the distribution system. These two systems will no longer use gas chlorination systems which are considered to be un-safe. New sodium hypochlorite generators will be utilized which will produce liquid chlorine from table salt.
Work on the iron removal treatment plants is expected to commence in March, 2008, and will be completed in April, 2009. The project will provide improved quality of water to residents served by these systems.

Construction of a Sewage Receiving Facility at Tucville

This project is made up of two components. The first comprises a sewer line to link the proposed sewage receiving facility at Tucville to the existing sewage ring main at Brickdam & Winter Place. This component was completed in 2007.

The work to be done in the second component consists of converting the existing sewage treatment plant at Tucville into a receiving station where sewage (solid waste) from the septic tanks will be deposited and then pumped through the recently completed sewer line to the existing sewage ring main. Work on this facility commenced in December, 2007, and is expected to be completed in June, 2008. This project will result in improved disposal of waste from septic tanks while still providing disposal of liquid waste from the homes of residents living in the Tucville area.

Refurbishment of the Shelter Belt Water treatment Plant

This project is also made up of two components. The first comprises the procurement of equipment and materials for the rehabilitation works at the treatment plant. The equipment includes a new standby power generator; a new sodium hypochlorite generator to produce liquid chlorine to replace the existing gas chlorination equipment; new filter media for all ten filters; new raw water pumps for the raw water pump station; new flocculators for the sedimentation tanks (to aid in the settlement of colour particles in the water); new dosing pumps for chemical treatment (lime and alum); and improvements in the electrical system. These items were all delivered in 2007.

The second component comprises a civil works contract to install the materials and equipment procured above and also includes ancillary works at the treatment plant such as repairs to the filter cells, repairs to the electrical system, clearing of the compound, etc. Work on this contract commenced in December 2007 and is scheduled to be completed in June 2008. This project will result in improved quality of water to residents of Georgetown served by this plant.

Rehabilitation of sewage pumping stations and street sewers

Twelve (12) of the existing twenty four sewage pump stations will be completely rehabilitated which will include replacement of sewer pumps and structural improvements to the pump stations. The remaining twelve pump stations will be rehabilitated under a project to be funded by the Government of Guyana. The sewage pump stations are in a deplorable state presently since only about one third of the pumps are in operation. The most common problems are damaged seals and motor failures. These problems have resulted in overflowing manholes and yard sewers with raw sewage being spilled into the streets and yards of residents. The proposed project will provide mechanisms for the elimination of the grit and solids in the system which will result in more efficient operation of the entire sewerage system and which will reduce maintenance significantly. Added to this, provision will be made for minor structural changes in the pump station buildings to provide for easier servicing of the pumps. This project is expected to commence in March 2008 and to be completed by the end of 2009.

A significant amount of the grit that enters the sewerage system comes from old and damaged yard sewer pipes which were originally constructed of clay material. Because of the brittle nature, inflexible jointing, and also the age of these pipes which were installed in 1929; these cracked or broken yard sewers allow a large amount of grit to enter the sewerage system. They also allow, during the wet weather, copious amounts of infiltration and inflow. The old C.I. street sewers are also suspected to be in a poor condition and approximately 16 kilometers need to be replaced. When the pump stations are not operating, a large amount of solid waste, sand and silt which enter the yard sewers tend to settle out in the street sewers, resulting in clogged sewers. This project, which is to be funded by the Government of Guyana, will provide for the replacement of about 60% of the street sewers. Work on this project is expected to commence later in the year.

Construction of the Agricola Trunk Main

This project is approximately 90% completed. The work was carried out under the East Bank Demerara roads project but could not be completed because the roads contractor experienced cash flow and other problems. The work to be done this year will include the construction of trench and road crossings, completion of gaps in the main and pressure testing. This main will provide security of service since it will link the Ruimveldt water system to those at Agricola and Eccles so that in the event of any problems at any of these systems, water can be pumped from either end to assist in providing a supply of water. This project is expected to be completed by July 2008.

Rehabilitation of Zones W2, W4 and W14

Rehabilitation works on the water distribution systems in Zone W2 (South Ruimveldt Gardens, Tucville, East & North East LaPenitence, East & West Ruimveldt), Zone W4 (Roxanne Burnham Gardens, Shirley Field Ridley Square, East & West Ruimveldt) and Zone W14 (Lamaha Gardens, Prashad Nagar, Campbellville) were essentially completed in 2007. This project included the installation of new transmission and distribution mains and water meters. Work is presently in progress to identify and permanently disconnect the old distribution mains from the system. This work is scheduled to be completed in April, 2008. This project will result in reduced water losses and wastage, and improved water pressure to residents in these areas.
