The plan needs to be corrected to accurately depict property lines and show existing easements. • A Tree Unit Calculation form was submitted that indicates a minimum of 8 tree units are required for this site. The site plan needs to show retained trees and proposed plantings to provide the required number of tree units. Trees may also be shown on a separate tree retention/planting plan. We need (5) copies of the modified site plans, only (2) copies of a separate tree plan.

PROJECT To construct a 3 -bedroom single-family residence. Water supply is a public source. Soils appear to support a low pressure distribution drainfield. II. TANKS The tank specified is an approved 1500 -gallon two-compartment concrete tank. The septic tank will be watertight and have locking risers extending to grade. The pump tank will be a 1500 -gallon single compartment concrete tank. The pump tank will have a locking riser extending to grade. The pump will be mounted and fitted so it can be easily removed and remounted without removing the float switches. Conduct watertight testing of all tanks, test to consist of 24-hour standing head test. No leakage is acceptable. No garbage grinder—if a garbage grinder is desired, the minimum septic tank capacity shall be 1750 gallons. III. AS -BUILT Pre -installation inspection, as -built inspection, pressure test, final cover inspection and other required as -built materials have not been paid as part of this design package. All additional inspections, field work, or other services required by the designer shall be completed at an additional cost. Payment in full is required prior to release of the installation permit.

Single phase, simplex timed dosing pump control. The Model TD control panel provides a reliable means of controlling one single phase pump in onsite septic installations. A programmable timer activates a magnetic motor contactor to turn the pump on and off. A low level cutout float overrides the timer to prevent the pump from running dry. An alarm float activates the audio/visual alarm system indicating a high liquid level. Common applications include sand filter systems, pressure distribution systems, mound systems, or any application requiring a timed dose. 1.
