The Project consisted of the following:

NSTP Location

• Construction of two 24.4m diameter settling tanks

• Construction of a Sodium Hypochlorite Building to housing 4 fiberglass tanks as storage for Sodium Hypochlorite solution, used in the treatment of the effluent in lieu of chlorine dosing, which is adverse to the environment

• Expansion of the holding pond

• Modification of the existing Metering Stations, for which bypasses were made to divert the flow temporarily, until new construction was completed

• Network of piping including RTR piping ranging from 4” to 40” diameter

AWTP Location

• Construction of one settling tank of 22.4m diameter

• Construction of a Sodium Hypochlorite building to house the fiberglass tanks as storage for the Sodium Hypochlorite solution used in the further treatment of the secondary effluent coming from NSTP

• Construction of a new irrigation pump station inclusive of civil, electrical, instrumentation, and piping works that houses two 250 HP irrigation pumps

• Construction of one 1.5 Million gallon steel storage tank inclusive of all related piping works

• Construction of a concrete structure housing 24 Continuous Backwash Filter modules to filter the incoming water

• Network of RTR piping ranging from 4” to 36” diameter

Basic Features

• The Project was completed on schedule, in 18 months

• 11,000m of underground C.S. pipe were cement lined internally; FBE coated externally and laid within the community area under difficult conditions such as rocky soil and existing utilities obstructions etc.

• 4,000m of RTR piping were laid within the community area while preserving Safety, Security and ensuring full noise abatement

• U.S. – European sourced equipment were all procured by MAC including but not limited to:
• 35 pumps ranging from 20 HP to 250 HP
• Drive units including structural steel assembly for 3 new settling tanks
• 24 filter modules inclusive of all pertinent piping connections to the Continuous Backwash Filter
• Architectural features such as Aluminum Domes, Handrails, Aluminum pyramids and Aluminum covers
• All instrumentation system including pressure indicators, transmitters, gauges, and flow meters
• A Programmable Logic Controller (PLC) System that is the control center of the project and through which the overall activities are controlled in Auto mode through a series of preset commands
• Numerous tie-ins requiring planning of manpower/material resourcing to ensure that all tie-ins were done during the time frame agreed upon with minimum disturbance to the community
