1 Introduction 

St. James is located on the north western side of Jamaica and is bordered on the east by 

Trelawny, on the west by Hanover and on the south by the parishes of Westmoreland and 

St. Elizabeth; the Caribbean Sea forms the northern boundary of the parish. St. James has a 

diverse terrain, with lovely white sand beaches all along the northern coastline, fishing 

villages and small sandy coves hidden among the rocks; the northern border of the Cockpit 

Country lies to the centre of the parish. 

The principal towns are Montego Bay, Anchovy, Cambridge, Adelphi, and Greenwood. On 

the southern boundary of the parish is Accompong, a Maroon settlement. 

The tourism industry has played a major role in the economic activity of the parish. It has a 

deep water pier at Montego Freeport, located near Montego Bay, where cruise ships and 

other vessels dock daily. The major hotels are located along the coastline and the major 

activities for night life located on Gloucester Avenue. 

NWC now provides water to some 74% of the population in St. James, which is an 

improvement over that in 2001 when the level of coverage was 58%. 

The reliability of service to those who are served by NWC operated facilities is estimated to 

average 19 hours per day. The average utilization rate of the parish is 70%. 

A Water Supply Improvement Plan has been prepared for St. James and this is presented in 

this document. A substantial portion of the proposed works is aimed at addressing the 

unacceptable high 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 water supply coverage to 92% of the parish 

population by end 2015, reduction in NRW level to below 30% of production and service 

reliability to 24 hours per day. 

2 Existing Water Supply System 

2.1 Water Resource 

Surface Water 

Some 68% of the water abstracted in the parish is obtained from surface sources. 

The following are the main surface sources in the parish: 

Great River 


6 | P a g e

Niagra River 

Sevens River 

Reading Spring 

Endeavor, Bluehole, Worcester and Mafoota Springs 

Tangle River 

Vaughnsfield Spring 

Dantrout and Stonehenge Springs 

The Great River basin has a yearly reliable surface yield of 12,826 million gallons 

(58.3 million m 3 ) per year. 

Ground Water 

In St. James, 32% of the water is obtained from ground sources. It is estimated that 

about 61,380 million gallons (279,000,000 m 3 ) of water per year is available from the 

groundwater resources within the Great River and Montego River watershed for St. James. 

There are six (6) wells that provide water to the St. James water supply system, with 

a combined average output of 3.83 mgd. This accounts for 18.6 % of the total 

average water production for the parish. The major wells in the parish are : 

Caanan 

Catherine Mount 

Irwindale 

Porto Bello 

Fairfield 

Pitfour 

2.2 Water Supply Systems 

The combined reliable yield from the thirteen surface sources is 13.7 mgd. The 

output from these sources range from 10.6 mgd during the dry period and increases 

to 16.5 mgd during the wet period. 

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.

Total length of pipeline within the parish is 1,200 km with the varying material types from CI, AC, GI, 

PVC, ST and DI.

3 NON-REVENUE WATER LEVELS 

Set out in figure 3.1 is the annual water balance for St. James. 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 34.15 million cubic meters 

(7.59 billion gallons) of water per year to the water supply network in St. James. 

Physical losses amount to 21.03 million cubic meters 4.63 billion gallons (4.63 billion 

gallons) per year, which represents 61.6% of the amount produced. 

In St. James, it is estimated that NWC derives revenue from only 8.65 million cubic 

meters (1.9 billion gallons) of water per year, which is only 25.3% of the water 

produced. 

It would be noted that 4.02M cubic meters (884 million gallons) of water is 

attributed to unauthorized consumption (i.e. 11.8% of production). This is largely 

due to illegal connections to some of the transmission pipelines to obtain water in 

red areas. 

Figure 3.1 – Water Balance for St. James 


10 | P a g e

National Water Commission (NWC) produces some 6,411 million gallons per year of water 

in St. James through twenty (20) wells and six (6) surface source supplied water treatment 

plants. The average billed volume from 38,972 accounts is only 734,602 m 3 /month which 

translates to average non-revenue water (NRW) of 2,161,916m 3 /month i.e. 75% 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. 

4 Water Requirement 

General 

4.1 Parish Population 

In 2001 the population in St. James was 175,127, which was a 13.6% increase over the 

154,195 in 1991, representing an average annual growth rate of 1.4%. Based on this 

growth rate, the estimated population in the parish in 2010 is 198,901 persons. 


11 | P a g e

It is estimated that over 75% of the population in St. James now has access to piped 

water. It is planned to increase this to at least 90% over the next 5 years. 

Demand Centres/Demand Zones 

The enumeration districts (EDs) that were used in the 2001 population census was used 

to establish priority areas that will be targeted to be provided with water supply. EDs 

with population densities in excess of 150 persons per square kilometres were grouped 

to form demand centres (DCs)/demand zones.

As far as possible, each demand zone is linked to a water supply system. It is related to 

a water distribution system that now serves it or has the potential to serve by it.

4.2 Current Water Requirement 2010 

Information on the water supply situation in the parish at 2010 is summarized in 

table 4.2 below. The average daily water production in the parish is 17.6 mgd 

compared to the base water demand (domestic, commercial, etc) which now 

averages 10.5 mgd and the technical losses (leaks, tank overflows, etc). There is an 

estimated overall supply shortfall of 4.4 mgd in the parish.

It is seen that without addressing the supply deficiencies in the parish, the situation will 

deteriorate significantly, with the overall water supply shortfall in the parish increasing tp 

6.4 mgd as the water demand increases.

4.4 Water Requirement in 2015 and 2030 - Technical losses Reduced to 30% and 

Plant Rehab Undertaken 

Set out below is the anticipated water supply situation in the parish in 2015 if an aggressive 

programme of works is implemented to : 

• reduce the level of NRW from the current level of 65% to 30% at most; and 

• major rehabilaition of the facilities at the water treatment plants, particularly the 

Great River Treatment Plant. 

The works to reduce technical losses include the replacement of aged and leaking pipelines 

as well as establishing an adequate pressure management system throughout the water 

supply network. 

The production capacities of some of the water treatment plants in the parish have been 

reduced as a result of factors, including the poor state of their raw water intake and 

conveyance system as well as that of the water treatment facilities. The rehabilitation of 

water treatment facilities will be done to increase uptime and thereby maximize water 

production.

It is expected that the improvement work will result in an overall water supply surplus in 

the parish. The water supply in systems such as Mafoota and Worcester will be augmented 

by water from adjoining supply systems which have sufficient water. 

It is also planned increase the export of water to Hanover, using the surplus water that is 

generated. 

The situation in 2030 is presented below and shows an overall supply surplus of 4.7 mgd in 

the demand zones in the parish. Where supply deficits exist, it is planned to import water 

from adjoining systems where there is sufficient water.

5.3 Detailed Audit of Water Supply System 

A detailed audit of the water supply system in the parish will be among the first 

key steps that will be undertaken to improve the water supply in St. James. 

This audit 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. Steps to reduce 

commercial losses such as identifying and removing illegal connections, will be 

informed by this audit 

The information will also 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. James. 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” 

Some of the benefits that are expected to be derived include 

o 

Improved network infrastructure 

o DMAs, pressure zones, SCADA etc. 

o Improved network data quality (GIS) 

o Improved asset management planning 

o High quality and continuous water supply service 

o Hydraulic network model 

o Extension of Service areas 

o Operational Improvements and Energy savings 

o Utility staff development 

• Specialist technical and managerial know-how 

• New technology and the know-how to use it efficiently

6 Water Supply Projects 

6.1 Cambridge Demand Zone (SJ-1) 

6.1.1 System Description 

The Cambridge Demand Zone is supplied with 1.3 mgd of water by the Cambridge Water 

Treatment Plant. This plant obtains water from the Seven Rivers and Cambridge Spring. 

6.1.2 Service Area 

Some of the communities included in this Demand Zone are Bickersteth, Seven Rivers, 

Richmond Hill, Shortwood, Retrieve, Cambridge, Ducketts, Grange, Bethel Town, Argyle 

Mountain, Greenwich, Lambs River, and Fern. 

6.1.3 Water Requirement 

The current population in this demand zone is estimated to be 4,880 persons and this is 

expected to increase to 5,838 persons by 2030. There is a current supply surplus of 0.1 mgd 

and this is expected to decrease to 0.06 mgd in 2030 if no improvement work is done. An 

aggressive programme to reduce the level of technical losses to 30% and rehabilitation of the 

plant to increase its uptime by 2015 will provide a surplus of some 0.7mgd; this surplus is 

expected to remain at this level through to 2030. 

Providing a surplus from the Cambridge Water Supply System would then make water 

available to augment the supply for the Dan Trout Water Supply Demand Zone or the 

Roaring River Demand Zone. 

6.1.4 Addressing the Supply Deficiencies 

Sections of the water distribution system are subjected to excessively high pressures while 

other sections experience very low pressures. The high pressures lead to frequent breaks and 

leaks on the water distribution system. It is planned establish pressure zones for this system 

which would facilitate significantly improved pressure management. 

The proposed works will include establishing DMAs, managing pressure, flows, levels in 

water tanks, rehabilitation and redesign of Treatment Plant and Intake works. More 

information on these are presented below. 


27 | P a g e


28 | P a g e

Water Treatment Plant Rehabilitation and Expansion of Water Stoargae Capcity 

The estimated average uptime of the Cambridge Water Treatment plant is 66%. During 

periods of rain the raw water pipline from the intake to the Cambridge Water Treatment 

Plant gets blocked by debris, thereby reducing raw flows to the plant which in turn reduces 

its output. It is planned to provide improved protective works at the intake and to install an 

appropriate system to ensure that the raw water pipline is kept clear at all times. This would 

include a system to occassional flush the raw water pipline. 

It is planned to increase the water storage capacity at Ducketts to enable arrangements to 

made to reduce cost of electricity at the Cambridge Treatment Plant (e.g. off-peak pumping) 

Water Supply Enhancement 

It is planned to complete the Fern Water Supply, by laying 0.8km of 50mm distribution pipe. 

This supply will be extended to serve some areas that are now being supplied by the 

Endeavour Water Supply System and thereby reducing the demand on that system where 

there is water supply deficit. 

General Non-Revenue Water Reduction NRW 

Steps will be taken to reduce the level of NRW on the system. This includes technical amd 

commercial losses. The works will include : 

• Creation of new flow/pressure zones and installation of gate valves, check valves, 

flow control valves, pressure sustaining valves, control mate, air valves throughout 

distribution. 

• Detailed micro DMA investigation (technical/commercial). 

• Reconfiguring of sections of the water distribution network. 

• House to house service connection investigation, replacement, repairing leaks on 

service connection and Consumer to Customer conversion. 

• Reactivation and installation of a new telemetry system for flow, level, pressure and 

water quality and to create an electronic library including flow, level and pressure 

data collected in the past years. 

• Metering and Geo referencing of all customers. Macro and micro metering, sizing, 

maintenance and replacement. 

• Use of information from a detailed anlaysis of the customer information system 

(CIS). 

• Updating hydraulic model to further simulate the distribution. 


29 | P a g e

• Installation of SCADA (Supervisory control and data acquisition) system to monitor 

Flow, pressure, water quality and level in real time 

Rehabilitation and Reinforcement of Small, Medium and Large Diameter Pipe 

Network 

In a further effort to reduce the level of technical losses on the water supply system, sections 

of the water supply network have been identified for replacement. These will include 

• Replacement of 12.2 km of Pipe 10’’ AC to 250mm From Cambridge Treatment Plant 

to Bethel Town 

• Network upgrade at Bickersteth, where almost 2 km of 4” pipe must be extended to 

Richmond Hill. 

• Network upgrade at Bickersteth playing field to Montpellier main road, where 

almost 2.2 km of 4”. 

• Replacement of 2 km of Pipe 1’’ GI to 50mm From Bickersteth square to Camp road. 

• Replacement of 0.4 km of Pipe 1’’ GI to 50mm From Bickersteth square to Johnson 

Common. 

• Replacement of 2 km of Pipe 2’’ GI to 50mm PVC from Bickersteth square to 

Plantation Heights. 

• Network upgrade at Bickersteth playing field to Copper Wood, where almost 2 km 

of 50mm. 

Low Income farming Settlement Environmental Improvement 

• Low Income settlement water supply and billing improvement. 

• Reduction Water consumed or wasted at low income settlements to reduce the high 

NRW ratio 

• Improve service by giving one connection per property with meter. 

• Removal of illegal connections to NWC supply network and the conversion of illegal 

users to active customers

6.2 Great River Demand Zone (SJ-2) 


The Great River Demand Zone is supplied with water from the Great River Water 

Treatment Plant. This plant obtains water from the Great River and was designed to treat 15 

mgd of water. Due to the state of major components of this plant such as the intake works, 

the raw water pipeline, the sedimentation and filtration systems, the uptime of the plant 

now averages about 68%. 


The Great River Demand Zone includes Montego Bay, Freeport, Reading Heights, Spring 

Gardens, Unity Hall, Guava Walk, Moy Hall, Flint River, Salt Spring, Brandon Hill, 

Rosemount, Felicity, Glendevon, Sun Valley Road, Catherine Mount, Mount Salem, Albion, 

part of Down Town MoBay, Salt Spring, Flower Hill, Cornwall Courts, Rose Heights, 

Rosemount Gardens, Bottom Rd, Norwood Housing Scheme, Norwood Capture Land, 

Anchovy, Rock Pleasant, Comfort Hall, Childermas, Lethe, Meggie Top, Flower Hill, New 

Town, Hopewell, Sandy Bay, Lucea, Tambrind Hill, Round Hill Hotel, Fiesta Hotel, Kew, 

Cliffton, Dolphin Head, Dias, Water Cress, Wood Lands, McQuarie, Sea View, Look Out, 

Bamboo, Catherine Hall, and Westgreen. 


The 2010 population of this demand zone is estimated to be 103,304 persons and this is 

expected to increase to 123,578 persons by 2030. There is a current supply deficit of 3.3 mgd, 

largely due to the low uptime of the facility. If the supply conditions remain the same, this 

deficit will increase to 4.7 mgd in 2030. 


Treatment Plant and Intake Works Rehabilitation 

The state of the intake works and the over 2 kilometer raw water pipeline to the Great River 

Water Treatment Plant is in urgent need of improvement to reduce disruptions in the flows 

to the Great River Water Treatment Plant. Issues faced include the high deposition rate of 

calcium carbonate inside the raw water pipeline and the frequent blockage of the intake, 


33 | P a g e

especially during rainy periods. The average output from the plant is 10.2 mgd compared to 

its design capacity of 15 mgd. The reliable yield of the Great River is over 80 mgd. 

The proposed works include : 

• Redesign and rehabilitation of the raw water intake and raw water pipeline 

• Rehabilitation of Great River Treatment Plant to restore treatment capacity to its 

design level. production capacity 

• Supply of Spare parts and materials to sustain production efficiency capacity and 

Preventative maintenance 

Steps will be taken to re-activate the Catherine Mount No. 1 and Belfield Wells which have 

a combined output of 4.2 mgd to augment the supply to this demand zone. 

Rehabilitation and expansion of Water Storage Tanks 

It is planned to carry out the following water storage tank rehabilaition/expansion 

• Rehabilitation of the Appleton Hall water storage tank and expanding its capacity 

from 1 million gallons to 2 million gallons storage capacity 

• Expansion of Terminal Reservoir from 3 million gallons to 6 million gallons 

• Replacement storage tank at McQuarie (50,000 gallons) 

Water level senors will be installed and linked to the proposed SCADA. 

Rehabilitation and Reinforcement of Small, Medium and Large Diameter Pipe Network 

DMAs have been established in some sections of the water supply system that serves this 

demand zone. It is planned to establish additional ones and have them linked to the 

SCADA which is to be set up. 

It is estimated that the level of technical losses on the system is some 65% of production. 

Sections of the water supply network are to be replaced to reduce losses. Sections on the 

distribution network experience excessively high pressures as a result of the the nonexistence 

of pressure zones in some sections of the water supply network, causing frequent 

main breaks. It is planned to rationalize pressure zones on the Great River Water Supply 

System. 

It is planned to carry out pipeline replace replacement/upgrading works across the parish. 

The major ones that have been idebtified are indicated below. 

• Replacement of Pipe 12’’ CI From Appleton Reservoir to Flankers (5.73 km) 

• (Down Town Montego Bay): Replace 0.025 km of ½” GI, 0.39 km of 1” GI, 1.3 km of

6.3 Appleton Spring Demand Zone (SJ-4) 


The Appleton Spring Demand Zone is provided with water from the Appleton Spring 

facility. Water is pumped from the spring into the water supply system. The designed 

capacity of this system was designed to treat 0.32 mgd of water. However, due to the poor 

state of major components of this facility such as the pumping station, leaks at the intake 

and the raw water pipeline, the uptime of the plant now averages about 69%. 


The Appleton Spring Demand Zone includes communities such as Sudburry, Rock Road, 

Latium, Over River, Hurlock, Appleton Spring, Orange, Siga, and Moore Park. 


The 2010 population in this demand zone is 3,200 persons and this is expected to increase to 

3,828 persons by 2030. There is a current supply deficit of 67,000 gallons per day, largely 

due to the low uptime of the facility. If the supply conditions remain the same, this deficit 

will increase to 95,000 in 2030. 


Pumping Station and Intake Works Rehabilitation 

The state of the pumping station and intake works is in urgent need of improvement. 

Carrying out the required improvement works will enable an increase in the average uptime 

of this facility. During rainy periods, the intake is often affected by single phasing, which in 

turn causes a disruption in the flow to the plant and reduction in the output from the plant. 

The average output from the plant is now about 0.2 mgd compared to its design capacity of 

0.32 mgd. The reliable yield of the Appleton Spring is over 1 mgd. Deficit in demand by 2030 

will be met by extension of 4.8km of 150mm from Caanan system which has a surplus.

6.4 Mafoota Demand Zone (SJ-5) 


The Mafoota system obtains water from a Spring and was designed to treat 0.33 mgd of 

water. Due to the state of major components of this system such as leaks, lack of storage and 

yield, the uptime of the system now averages about 64%. 


The Mafoota Demand Zone includes communities such as Mafoota, Roehampton, Rocky 

Hill,Wales Pond, Lawson, Comfort Hall and Windsor Castle. 


The current population in this demand zone is estimated to be 5,654 persons and this is 

expected to increase to 6,763 persons by 2030. There is a current supply deficit of 0.18 mgd, 

largely due to leaks and yield. If the supply conditions remain the same, there will still be a 

deficit of 0.22mgd in 2030. 



The state of the distribution is in urgent need of improvement to reduce the impact on 

downtime. During rainy periods, the Spring is often affected by low yield resulting in major 

disruption in flow to the communities and reduction in the output from the plant. The 

average output from the Mafoota is 0.2 mgd compared to its design capacity of 0.3mgd. The 

reliable yield of the Mafoota is unknown. Deficit in demand by 2030 will be enhanced by 

Great River.

Non-Revenue Water Reduction (NRW) Activities 

It is planned to establish DMAs within the water supply system as one of the first set of 

steps to develop a comprehensive NRW reduction programme. This will include the 

replacement of sections of the water supply network to reduce the level of technical losses. 

The replacement of the old and leaking 4 inch diameter CI pipe along Mafoota main road 

has been identified as priority and will be undertaken early in the programme. 

Sections on the water distribution network are subjected to high pressures as a result of the 

the non-existence of pressure zones in some sections of the water supply network, causing 

frequent main breaks. The Mafoota Water Supply System will be sectionalized into pressure 

zones to reduce these occurrences and facilitate improved pressure and distribution 

management. 


NWC will take steps to regularize supplies in the informal settlements, where a number 

residents are obtaining water illegally. thereby reduce the commercial losses. This activity 

will involve streamling the water supply network and removing the “spaghetti” water 

supply network that exist there. NWC will target thaose who have illegally connected to its 

supply network and convert these water users to NWC customers.

6.5 Reading Demand Zone (SJ-6) 


The Reading Demand Zone is supplied with water from the Reading Springs, which has a 

licensed abstraction rate of 1.03 mgd of water. Water is harnessed and pumped into the 

water supply network. The average uptime of this facility is estimated to be 87%. 


The Reading Spring Demand Zone includes communities such as Spring Gardens, Moy 

Hall, Bouge Hill, Bogue Heights, Bogue Village, Bogue Industrial, Ramble Hill and Reading. 


The 2010 population in this demand zone is estimated to be 9,232 persons and this is 

expected to increase to 11,044 persons by 2030. There is a current supply deficit of about 

0.10 mgd, largely due to pumping downtime, inadequate water storage capacity and 

leaks. If the supply conditions remain the same, there will still be a deficit of 0.1mgd in 

2030. 



During rainy periods, the Reading Spring is often affected by low voltage, resulting in 

disruption in pumping and supply to the communities served by this system. The average 

output from the Reading spring is 0.87 mgd compared to its design capacity of 1.03mgd. 

The reliable yield of the Porto Bello is unknown. 

One of the measures to address the water supply deficit will be the rehabilitation and 

upgrading of intake that harnesses water from the spring to increase the water production 

to 2.2 mgd. The pumping station will aslo be refurbished to fully utilize the additional 

water from the upgraded springs and to improve the efficiency of the pumping equipment 

to reduce electricity usage. 

Reduction in Technical Losses 

Sections of the water supply network are to be replaced to reduce losses It is planned to 

rationalize the existing pressure zones in the Reading Water Supply System to better accord 

with the current and expected supply requirements. 


50 | P a g e

Rehabilitation and expansion of Reservoir 

The water storage capacity of the Bogue Hill water tanks will be expanded by constructing a 

new tank. This will be part of the measures to improve supply management and operational 

efficiency. 


The NWC customers in Moy Hall are affected by an inadequate level of service and this will 

be addressed by a project that will involve (i) replacing the pipeline to the area from the 

Great River/Reading trunk main; constructing a booster station to boost the supply to a new 

tank. 


It is planned to carry out pipeline replace replacement/upgrading works to reduce technical 

losses and improve service levels. The major activities that have been identified for 

immediate action are presented below/ 

• Complete the installation of 1 km of the 12 inch diameter DI pipe between Spring 

Gardens and Reading, in order to provide an improved to Coral Spring 

• Extension of 4km of 100mm from Bogue Village 150mm tee along Ramble Hill main 

road and transfer all existing customers from the high pressure pumping main to this
