BACKGROUND
* The Lusignan borehole was constructed in 1968 to a depth of 280m with borehole diameter of 100 mm made of everite casing with PVC screens.
* The borehole operates using an 80m3/hr @ 60 m head pump.
* The present service pressure in the area is poor, with less than 0.2m nearest to the well and diminishing to ground level at the 100 yds radius line.
* The borehole is not performing satisfactorily and its condition is such that failure is imminent.
* A camera inspection of the borehole was conducted on May 26, 2006, from which it was revealed that the casting has visible factures throughout the bore.
* An analysis indicated that the borehole has an effective remaining life of less than four months and as such needs to be replaced urgently.
* The replacement of the borehole will allow for an increase in service pressures as fewer losses will be accrued at the source due to its improved condition.
* The final result will be an increase in service levels through out the village.
* The new well will not only have the capacity to serve the existing community, including the market, but will also have the capacity to cater for a 20% increase in households.
* Guyana Water Incorporated’s system in each division is a continuous network of pipeline with control valves placed at strategic locations, this allows the entity to effectively maintain the system and make optimal use of the water resources. The existing network, therefore, is connected to adjacent systems. This system is in good shape and will not require upgrading.
New Developments
* This project will make it possible for the residents of the village of Lusignan to continue to get regular and adequate supplies of potable water for their daily use before the old well becomes non-functional.
* Improve the flow of water and provide an adequate supply of potable water which will encourage better sanitation and other oral health practices. The stress of having to fetch and cope with limited quantities of water will also be removed.
* The Lusignan well is located on the East Coast Demerara, Region #4.
* Approximately 2000 persons are expected to benefit from this well which will be done at an approximate cost of G$51M.
* This well is expected to be completed in 93 days by a Trinidadian based Contractor “Water and Oil Wells Services” and Consultants “CEMCO”.
* The new borehole for this well will be to a depth of 280 meters or 918 feet with well casings and stainless steel borehole screens.
* Further the system will incorporate submersible pumps with electrical control panels and discharge pipe assembly.
* A pump house and fencing will be constructed for the entire assembly.
* No maintenance will be needed for the first five years.
* During implementation of this project it is envisaged that approximately 360 persons will be employed.
Developmental Works Completed on East Coast Demerara
* In 2003, approximately 1800 persons benefited from the Installation of Pure Water Distribution Network (3 Km of PVC pipes ) and upgrading of well in Block “12” Non Pariel at an approximate cost of G$17M.
* In 2004, approximately 1800 persons benefited from the Construction of Roads, Drains and Structures (4 kilometers of roads with DBST finish, 8 kilometers of roadside drains and 2drainage culvert) Block “12” Non Pariel at an approximate cost of G$65M.
* Approximately 4000 persons benefited from the Construction of Roads, Drains and Structures (9.6 kilometers of main and secondary roads with DBST finish, earthen roadside drains and 37 culverts) Tract “A” Good Hope at an approximate cost of G$195M.
* Approximately 4000 persons benefited from the Installation of Pure Water Distribution Network (3 kilometers of PVC pipes and 18 fire hydrants) in Tract “A” Good Hope at an approximate cost of G$26M.
* Approximately 3000 persons benefited from the Construction of Roads, Drains and Structures(8 kilometers of main and secondary roads with DBST finish, earthen roadside drains and 28 culvert) Foulis at an approximate cost of G$195M.
* Approximately 3000 persons benefited from the Installation of Pure Water Distribution Network (473meters of PVC pipes and servicing of over 5.5 kilometers of existing PVC pipes) in Foulis at an approximate cost of G$32M.
Current Developmental Works on East Coast Demerara
* Approximately G$240M will be spent on the East Coast Transmission interlink, Lusignan and Mon Repos service connection upgrade, Plaisance and Good Hope service connection where approximately 30,000 persons are expected to benefit.
Future Developmental Works on East Coast Demerara
* Area “B” Lusignan approximately US$500,000 to be spent on developmental works.
* Section “EE” Non Pariel approximately US$720,000 to be spent on developmental works.
* Binkey Alley, Lusignan approximately US$150,000 to be spent on developmental works.
