Upper Ringwood Zone Water System
Zone Water System Upgrade
Ringwood, NJ
The Borough of Ringwood needed to upgrade the Upper Ringwood Zone Water System. The Upper Ringwood Zone is located at the far end of the Ringwood system and depends upon supply from wells and a Passaic Valley Water Commission connection situated in the southern lower pressure zone.
The Upper Ringwood Zone provides storage in the zone and boosts the chlorine residual by sodium hypochlorite injection where water enters the zone. As a consequence of the rugged mountainous terrain, the supply to the zone is from a higher pressure gradient zone. Water flows through an aerial pipe section over a tributary to the Wanaque Reservoir and then to a pressure reducing valve chamber. Due to age and the high pressures upstream of the pressure reducing valve it was determined that new facilities with modern control and data acquisition was appropriate for a water system upgrade.
Work performed under this contract included communications studies to coordinate the transfer of information for control of operations in the zone, environmental permits from the New Jersey Highlands Council, and design documents for a Safety Panel Control Building. The building was designed to contain chemical mixing facilities, chemical feed pumps, chlorine residual continuous sampler and a SCADA PAK system for local control and monitoring. Radio equipment was provided to monitor tank levels. A chemical injection chamber located near the building was rehabilitated to include a closed loop flow modulating valve, a new flow meter, a high capacity pressure reducing/sustaining valve and control signals for the SCADA PAK system. The aerial pipeline was insulated, heat tape traced and fitted with temperature sensors with radio transmitters.
We incorporated a topographic map for the Municipal Building into a base map for the preparation of a Site Plan of Improvements. A radio study was also performed to establish antenna heights and directional orientation of radio equipment for communications between the proposed Safety Panel Control Building site, the aerial pipeline and the Upper Ringwood 500,000 gallon water storage tank. We submitted an application to the New Jersey Highlands Council for a waiver from planning requirements on the basis of existing water utility replacement exemption.
Construction documents were prepared by H2M for use by Ringwood to solicit bids for the construction of the project and bid phase assistance to procure the services of a qualified water system contractor. We also provided contract administration, construction observation, and commissioning consultation during the project startup and during the two year maintenance period
