Draft St. Catherine WS PPLan – October 12 2011

1.0 Introduction St. Catherine is located in the south-eastern section of Jamaica. Its western boundary is with the parish of Clarendon. The eastern boundary follows part of the Ferry River as well as borders with St. Mary and St. Andrew. The northern boundary is with St. Ann and St. Mary. The Caribbean Sea borders St. Catherine to the south. National Water Commission (NWC) produces over 1 billion gallons of water per month in St. Catherine through thirty – four (34) wells and five (5) surface sources. The average billed volume is only 300 million gallons per month which translates to an average non-revenue water (NRW) of 700 million gallons per month i.e. 70% of production. This unacceptable level of NRW has had an adverse impact on the level of service provided to the people of the parish and on its financial performance and that of NWC. NWC now provides water to some 90% of the population in St. Catherine. However, the reliability of service to those who are served by NWC is estimated to average 16 hours per day. A Water Supply Improvement plan has been prepared for the parish and is presented in this document. The WSIP for the parish will involve an expenditure of $5,290,917,230.40 over the next twenty years in carrying out a number of water supply rehabilitation and upgrading works. A substantial portion of the proposed works is aimed at addressing the unacceptable level of NRW through the replacement of major sections of the aged and undersized water supply infrastructure and improvement in water supply pressure management. It is planned to increase service reliability to 90% to the parish population by end 2030.

2.0 Existing Water Supply System

2.1 Water Resource Surface Water Some 7% of the water abstracted in the parish is obtained from surface sources. The following are the main surface sources in the parish: Rio Cobre Rio Pedro Mango Gully Indian River Rio Doro

Fresh to brackish water may be sourced from: Fresh River Salt Island Lagoon Salt Island Creek Colburns Gully

Ground Water Karstified limestone and alluvial aquifers may be tapped into for groundwater. The areas identified as most appropriate for groundwater exploration is in central and northern sections of the parish.

2.2 Water Supply Systems An extensive network of some 34 production wells as well as treatment plants supply the St. Catherine region with potable water. The supply systems and their sources are as follows:

• Spanish Town and its immediate environs are supplied with drinking water from a system consisting of some ten (10) production wells and a water treatment plant. The supply sources have a combined estimated average daily output of 11.7 mig; • Portmore is fed on average 5.1 migd of potable water from some 13 production wells;

Draft St. Catherine WS PPLan – October 12 2011

• The Linstead/ Ewarton/ Bog Walk water supply system consists of six (6) wells which supplies the region with an estimated daily average of 6.7 mig of potable water. The system may be supplemented with water from the Bybrook No. 3 Well which primarily supplies the Rio Cobre System; • The Old Harbour water supply system is supplied from three (3) well sources. These four production wells have an estimated daily output of 2.5 MIG. • The Rio Cobre system, originally designed to produce 13.5 MIG of potable water on a daily basis has the following raw water supply sources: o Tulloch Spring o Bybrook Well 1, 2 & 4 o Eastern Headwork’s Well H, W & G The Rio Cobre Water Supply System supplies sections of Kingston and St. Andrew, Spanish Town as well as Portmore with potable water. The Kingston Metropolitan Area (KMA) Water Supply Project was undertaken jointly by the JBIC and GOJ aimed at improving all the existing water systems in the Greater Spanish Town, South East St. Catherine and ultimately increasing the production capacity in the parish. The water supply network throughout the parish is aged and undersized, contributing to unacceptable level of service there. Information on the water supply network is summarized in table 2.1 below.

3.0 NON-REVENUE WATER LEVELS Set out in figure 3.1 is the annual water balance for St. Catherine. This was derived from the water balances that were prepared for each of the water supply systems in the parish. The water balances are based on flow measurements that were conducted at sections of the water supply network and examinations of customer and records. NWC water production facilities provide approximately 54.26 M cubic meters of water per year to the water supply network in St. Catherine i.e. 11,937.2 M gallons per year. Physical losses amount to 29.5 M cubic meters (6,490M gallons) per year. This represents 54% of the amount produced. Revenue water in the parish is only 10MGD which is only 32% of the water produced. It should be noted that over 22,000 accounts attributes to unauthorized consumption. This is largely due to illegal connections to some of the cross country transmission pipelines to obtain water for irrigation. Figure 3.1 – Water Balance for St. Catherine

5.0 Water Supply Improvement Plans

Introduction It is planned to undertake a number of water supply improvement works in St. Catherine to address supply deficiencies and to improve overall operational efficiencies. The planned works will focus on reducing the high level of technical losses (estimated to be in excess of 54% of production), largely due to the aged water supply infrastructure; strengthening the transfer capacities of critical water transmission mains, to enable transfer of water within and between water supply systems and facilitating supply flexibility between water supply systems; and water supply extensions to areas that are not now been served. A comprehensive audit of the water supply systems in parish will be undertaken early stages in order to identify optimal steps that should be taken to deliver early gains in the reduction of NRW. This will include establishing district metered areas (DMAs) and setting up monitoring systems.

6.0 Addressing the Supply Deficiencies Set Up and Detailed Audit of the St. Catherine Water Supply System The level of NRW in the parish is unacceptably high. As shown in the sections above, the overall NRW is 68% of production. It is planned to carry out a programme of activities to target areas to reduce overall NRW in the parish. A detailed audit of the water supply system will be undertaken as well as a comprehensive survey of users – legal and illegal. In order to proceed with the audit of the network and to obtain reliable and accurate information on users and consumption, the following activities is required to be implemented within the Parish during the Audit Phase:

Draft St. Catherine WS PPLan – October 12 2011

Technical Area: • Network survey to define and locate pipes (material and size) & fittings (valves, PRV, fire hydrants) to draw up the network inventory. Then all the information gathered on site will be transferred in Geographic Information System (GIS) following the NWC specifications. • Investigation of all the NWC facilities (production facilities, reservoirs and pumping stations). All defects and anomalies detected and remedial works for repairs and/or upgrading have must be clearly stated for every facility. • Flow & pressure measurements as well as level measurement of reservoirs at production facilities, on the trunk mains and various off-takes. • Leak detection campaign on the entire network and mapping of leaks detected to further decide for pipe section replacement. • Establishment and set-up of network models complying with the network operation and measurements carried out. • Network partition into District Metering Area (DMA) to monitor flows and NRW control with definition of equipment (valves and bulk meters) to be installed. • Setting-up of pressure management program including evaluation of existing pressure zones and Pressure Reducing Valves (PRV) and definition new pressure areas with location for new equipment.

Commercial Area: • “Door to Door” Consumer survey audits to ascertain specific elements of the water supply among the residential & commercial users: to locate the NWC users (mapping under GIS), to check the status and condition of water meters installed on site, to gather other relevant information regarding the supply and to find out illegal connections. • CS analysis to check the reliability and accuracy of the NWC database, to analyze trends of consumption and users and to establish the initial billable consumption. • Consumption profiles measuring campaign to analyze the apparent losses engendered by the customer metering policies and thereof to optimize the invoicing /revenues of NWC by defining new metering policies for domestic and commercial users. • Specific investigation on site to check the discrepancies between the CS database and the field, mainly for the temporary and permanent disconnected accounts as well as for the accounts with zero/low consumption.

Cost of Audit The total cost to undertake the proposed set up and audit of the St. Catherine water supply system is $92M. A breakdown is provided in the table below.

Expected Benefits The detailed audit of the St. Catherine Water Supply system will provide information that will be used to help in defining detailed NRW reduction intervention activities. The results of the audit will be used to target the most critical sections of the parish water supply system that require attention and assist in scheduling of the required works. The information will be used to populate the asset database for the parish which will form a critical part of the asset management system (AMS) that will be established for St. Catherine. A fully functional AMS will be a valuable operational tool that can be used to sustain the benefits that will be derived from the various projects and activities that are set out in this document.
