Info

No start-up can begin without the Department representative on site. 18. Public Notification Advisory signs must designate the nature of the reuse and must be posted in areas where reuse is practiced. Advisory signs shall be posted at entrances to golf courses including the first and tenth tees and entrances to residential neighborhoods where reclaimed water is used for landscape irrigation. These Advisory signs must include the text: “Do not drink” in English and “No beber” in Spanish together with the equivalent standard international symbol. Advisory signs shall be posted adjacent to lakes/ponds or other decorative water features used to store reclaimed water. These Advisory signs must include the text: “Do not drink”, “Do not swim”, and “No beber”, “No nadar” in English and Spanish, respectively, together with the equivalent standard international symbols. There are no specific size requirements for advisory signs, nor are there any requirements on the number of signs to be provided at sites using reclaimed water. The use of purple as a prominent color on advisory signs and written notices is recommended. However, all signs should be clearly legible, and enough signs shall be posted to ensure reasonable notice to the public. Further reference to the requirements of advisory signs may be found in Department Rule 62-610.468, F.A.C. Also, Reference the Department’s Standard Details. 19.

1. General Section VIII Pressurized Reuse Connection Controls It is the intent of this specification to provide Martin County a means to control and monitor the delivery of reuse water to each connection point of the distribution system. The pressurized reuse system shall be constructed where the County determines that a pressurized system is needed. The controls, which are normally located at the delivery point of each development, will consist of the following components: (see details) a) A Reuse Control Panel (RCP), including a programmable Motorola MOSCAD-ACE controller, Motorola trunked radio (model number to be provided by DCR) and flow indicator/interface to receive pulse signals from a flow transmitter. b) A 85-264 VAC power supply (15 amp minimum) to power RCP and control valve. c) A flow sensor device that transmits a signal to a pulse output transmitter. d) A master valve with maximum flow/pressure reducing and 120 AC volt solenoids. e) A flow transmitter that sends pulse signals to a flow indicator/interface in the RCP. f) Surge protection with three rods spaced eight feet in a triangular grid as detailed. 2. Reuse Control Panel (RCP) and SCADA The control panel shall combine electro-mechanical controls and a programmable microprocessor based Remote Telemetry Unit (RTU) controller to be capable of fully automatic or manual operation. The controls shall be housed in a 16-gauge seamless NEMA 3R/12 stainless steel enclosure with drip shield and padlockable 3 point latch. Enclosure shall be mounted on the power pedestal. The control panel shall operate on 117 VAC and be capable of actuating up to two 120 VAC 7VA solenoid valves per station, plus a master valve relay. The RTU controller output shall be protected against severe electrical surge using isolation relays and/or surge protection devices. The RCP shall be capable of manual operation and can be programmed to run daily or weekly programs. Programs shall allow for a measured quantity of reuse water delivery during specified time intervals up to 24 hours. A high flow rate alarm shall override the running program and stop reuse water delivery until a reset command has been entered through the SCADA system. Program schedules and set points shall be entered through 62
