11 Typical Low-Pressure Sewers

12 Benefits of Low Pressure Sewers Cost significantly less than gravity sewers 30-60% Lower cost of construction 30-50% Lower cost of ownership Faster installation +/- 5 times Less impact to residents and infrastructure (can be directionally drilled) Eliminates inflow and illegal sump pumps and area drains Does not promote groundwater displacement Reduce or eliminate sewer line flushing maintenance

13 Typical Grinder Pump and Sewer Lateral Installation Typical Grinder Pump Lateral kit including shut-off and check valve Alarm Panel 1 Hp Motor, Single Phase, 120 / 240 V Sewer main Grinder pump Standard pump chamber is 8 deep can be deeper if there is existing basement services Alarm panel mounted on the side of the house Power supplied from existing home power supply Typical Pump Alarm Panel

14 Grinder Pump Installations

15 Finished Grinder Pump Installations

16 Who pays for what? Project will pay approximately $10,000 per house for: $8,200 - Furnish and install grinder pump, including electric supply $700 - Furnish and install lateral kit (FM to pump) $1,100 - Furnish and install 20-ft of gravity lateral from pump, including trap, vent and cleanout Grinder pump installation includes full site restoration to pre-construction conditions

17 What about the electric supply? If you have room in your existing breaker box, the project will install new breaker(s) in the panel and conduit and wiring to the Pump Alarm Panel. If you have no room or load capacity in your existing breaker box or have fuses, the project will install a new Main Service panel next to the electric meter. New panel will provide power supply to existing panel and Pump Alarm Panel.

18 Typical Homeowner Costs One-Time Sewer Connection Cost 4 PVC Building Sewer, length will vary Estimated cost per foot ~ $35 to $45/ LF 10 feet = $ feet = $900 Internal piping modifications may be necessary. Approximately $600 to decommission septic system per DOH requirements Permanently disconnect tank from building Pump out tank and fill with stone or flowable fill Cost Saving Opportunities Homeowner dig/backfill trench Homeowner complete surface restoration Multiple neighbors contract with single contractor for economy of scale savings

19 How much will it cost to operate my grinder pump? Approximately $2.50 a month (~$30/year) for an average single family household (125 gpd) Grinder pump electrical cost will be included in monthly electric bill Grinder pumps in perspective:

20 Where will my grinder pump go? Preliminary design will include every house to be assessed by engineer to identify: Location of septic system Location and type of existing power supply/meter Basement type Any basement service Type of property Individual grinder pumps Alarm panel/pump visible from street Alarm/shutoff adjacent to grinder pump As close as feasible to existing bldg. sewer and house

21 What happens during power outages? Water Consumption During Power Failures Gallons Usage Appliance Normal *Emergency Automatic Clothes Washer 15 0 Water Closet Bathtub 30 0 Dishwasher 15 0 Kitchen Sink Shower Stall 45 0 Lavatory TOTAL Natural Forced Water Conservation Available storage in grinder pump (minimum 70 gallons) Manufacturer study 70 gallon grinder pumps have adequate storage for an average family for 97% of the national power outages Outlet for generator (6kW minimum) for extended power outages Town District will have a portable generator

22 What about ownership and maintenance? Pump and control panel will be owned and maintained by the Sewer District No. 3 Town will need easements from each property owner: Temporary easement for installation of grinder pumps Permanent easement for grinder pump maintenance and repair Routine pump maintenance between 8 to 10 years

23 How will I know if there s a problem? Fully functional alarm panels Easy Troubleshooting UL-listed NEMA 4X watertight, non-corrosion FRP enclosure Generator Receptacle Protection Package Low water cut out High pressure cut out Brown out cut out Call the Town in the event of an Alarm!
