Water System Improvement Project

Project Overview This project aims to enhance the City of Greenwood's water infrastructure for reliable, safe drinking water supply. Total Project Cost: $4.2 Million. Grant Funding: $3.1 Million. City of Greenwood Contribution: $1.1 Million.

Key Components

Water Reservoir: An above-ground, rebar-reinforced concrete reservoir is proposed, with alternatives considered for cost-effectiveness. Size and capacity will be finalized during detailed design.
Leak Detection: Using conventional technology with listening devices attached to valves or hydrants to detect leaks in pressurized pipes. Technicians pinpoint locations by comparing sounds from multiple points. This is being applied across the entire Greenwood water system to identify and repair in-ground leaks.
Treatment Building: Proposed alongside or above the new reservoir to house treatment systems. Includes:
- Disinfection treatment to comply with Interior Health Authority (IHA) standards, likely using sodium hypochlorite (liquid chlorine) with storage tanks, dosing pumps, pipework, and a transfer pump. Alternatives exist, but this is the most cost-effective option at a dosing rate of 2 parts per million.
Pump Station: A two-pump (alternating) system inside the treatment building to distribute treated water through the city's network.
Alterations to Existing Wells:
- Wells #4 and #5 assessed for adequate surface annular seals and casing heights; existing pumps replaced.
- Cost analysis for repair vs. replacement of Well #4. If replacement is beneficial, install proposed Well #6.
- Connect Well #6 to the treatment building; make Wells #5 and #6 primary, decommission Wells #1, #2, and #4 (or keep #4 as backup).
SCADA System: Review and replace existing system. New system to include mobile alarm notifications, potential mobile adjustments, and integration with wastewater treatment plant and sewer lift stations. Specifications during detailed design.
Decommissioning of Existing Reservoir: The current reservoir will be decommissioned.
Addition of Backflow Preventer Valve: Installed at the boundary between Greenwood and Anaconda water systems to prevent contamination.

Project Benefits Improved water quality, reduced leaks and waste, enhanced system reliability, and compliance with health standards, benefiting all residents with safer drinking water and lower long-term costs.

Timeline Detailed design phase ongoing; implementation to follow based on funding and assessments. Updates will be posted here.
