As follow up, please note, I mis-spoke about the direction of all Valves; the Water Spec requires Open counter-clockwise/Left (Closes Right) Yes, all ductile iron pipe shall be Class 52. Required brass wedges at every joint Each residential unit will be required to have its own meter pit per Ledyard’s WPCA new policy 8.14. Units with slabs and with basements will have the meter in the pit, outside of the house You indicated that the services will be domestic only (no sprinkler lines to the units) For this reason, no back flow device will be required The 1” meter pit spec is attached for reference. Spec #8 Meter horns are not permitted GU will provide meter spacers GU will provide a Water Service letter with estimate once the Final Site Plans are approved We do encourage early communication with GU Meter Crew (860) 446-4077 GU will review Submittals GU will perform the tap at the main in the road, contractor is responsible for permits, trench box, exposing the main, traffic controls, etc. EG Homes (not the Ledyard WPCA) will remain the long-term owner of the water infrastructure once it is installed (it will be considered private/customer-owned water main & hydrants). Please see the Spec #5, attached, for sewer and drain crossings – for areas where the required 10’ horizontal separation of water and sewer is not possible; Options include sleeving the water line, replacing sewer lines with water class pipe or surrounding the line entirely with Flowable Fill. Generally, deepening the sewer mains could also be considered to achieve the vertical clearance (18” height) For the sewer laterals – sleeving the adjacent water services or using water class pipe for the laterals are options to consider When sewer is above the water, advise replace sewer pipe with water-class pipe (Blue Brute) , and 18” of vertical clearance required As an alternative, we allow Flow-able Fill to surround the line. When water is above the sewer/drain, there is a minimum required 18 inches of vertical clearance. With the current routing of the sewer mains and water services, There are significant numbers of crossings Mueller Super Centurion 200 model A-423 hydrants meet the Water Spec Operating nuts shall turn counterclockwise to open the hydrant Required Color: Sherwin Williams Industrial Safety Yellow, B54Y37 Hydrant nozzle cap chains to be removed when being placed into service Please let me know what other questions you have, Thank you, Kate Kate Blacker Project Management | Technical Aide Water & Wastewater
