2. Purchase low pressure pumping unit and appurtenances (Assessed areas – low pressure pumping unit price included in assessment) 3. Arrange for pick up of low pressure pumping unit and appurtenances (at District)

Contractor to conduct Continuity test on pumps upon pickup. 4. Arrange for MANDATORY preconstruction meeting at site with:

District Inspector (Call Rick Philbrick to setup 561-262-3456) Contractor Property Manager or Homeowner Electrician Plumber

5. Inspection schedule must be followed (listed in chronological oder): A. Wetwell Inspection

Plumbness/Level Anti-floatation Concrete Rim elevation to be 2”-3” above finished grade

P a g e | 2

B. Electrical Inspection

After electrical appurtenances are installed and approved by Municipality or County, District to be notified for inspection (24 hour notice required).

Contractor/homeowner not to energize control panel until all inspections have been completed and approved and, only with District inspector on site.

C. Pump Startup Test

Continuity test Draw down test Pressure test on 1.25” effluent line

D. Plumbing Inspection

Plumbing may be moved from septic tank to wet well upon a passing pump startup and must be inspected by District staff.

E Septic Tank Abandonment and Fill

LOW PRESSURE SEWER SYSTEM

GENERAL OPERATING INSTRUCTIONS

GENERAL INFORMATION Your home is equipped with a wastewater disposal system known as a low pressure grinder pump system. The key element of the system is the self contained grinder pump unit. The fiberglass tank, which houses the pump, collects all the effluent from your house which previously discharged to a septic tank. The solid materials are then ground to a small size suitable for pumping as a slurry with the effluent water. The grinder pump generates sufficient pressure to pump this slurry from your home through a low pressure force main to the nearest existing sanitary collection system. There are shut off and check valves that isolate your pumping unit from the low pressure force main in the street right-of-way. These valves are located in boxes at your front property line and at the pumping unit. You should be familiar with their location and operation in the event on site repairs are necessary. Additionally, you should make a location sketch of the small PVC force main between the pumping unit and the street right-of-way line. Keep this sketch in a safe place for future reference. The District can assist you in locating these valves. Listed below are typical instructions that are being recommended to users of a grinder pump low pressure system:

1. The following items should not be introduced into any house sewer, either directly or through a garbage disposal unit:

a. Glass b. Metal c. Cloth (socks, rags, etc.) d. Plastic Objects (toys, utensils, etc.) e. Diapers, Diaper Wipes, Sanitary Napkins or Tampons f. Fats, Oils and Grease (FOG)

g. Bones and other grease laden products

2. Grease - Grease in the wet well is a major cause of system backups. Float switches, which regulate the liquid levels in the pumping chamber, can be made inoperative by accumulations of grease on the float system. As with any sewer system, every effort should be made to remove grease from dishes and eating utensils prior to operating dishwashers and garbage disposal units.

P a g e | 2

3. Never introduce into any sewer: a. Explosives b. Flammable Material c. Lubricating Oils and/or Grease d. Strong Chemicals e. Gasoline f. Paints

4. Unoccupied Homes - If your home is left unoccupied for longer than a week or two, the pump system should be purged, i.e. run clean water into the pumping until the pump starts. Turn off the water supply and allow the pump to run until it shuts off automatically. Do not disconnect power to the unit. 5. Power Failure - Obviously, like other household appliances a grinder pump cannot operate and dispose of wastewater without electrical power. The storage capacity of most units varies between 70 and 80 gallons. This is an adequate reserve for an average one family home for at least 24 hours if water usage is kept to a minimum. Keep in mind that the normal toilet uses about 3 to 5 gallons per flush. 6. Pump Failure Alarm - Your low pressure grinder pump contains a built in alarm signal which will activate in the event of a high liquid level in the basin. This signal is connected to a visual and/or audible alarm which will provide you with adequate warning that service is required. During the interval prior to the arrival of a service technician, water usage should be kept to a minimum. During normal working hours you can call 747-5709 for an emergency. After hours, the emergency number is 747-5708. 7. District Response in Emergencies – Maintenance of the pumping unit and its components will be the responsibility of the District for all residential and 3 phase non-residential low flow units. The covers all labor involved for emergency calls or normal maintenance and any parts or materials that are used.
