A site evaluation indicated the site to have suitable soil for an aerobic surface irrigation system. The lot has a slope of less than 15 percent in the proposed spray area. The existing vegetation consists of some native grasses along with Live oak, Madrone and Juniper trees. (See landscaping section for additional requirements.) The residence will utilize a well for potable water. All of the system's tanks will be 5 ft. away from all wells. The proposed spray irrigation area will be 1 ft. from all wells. The site is not over the Edwards Recharge Zone or in a regulated 1-year floodplain. No recharge features were found within 15 ft. of the proposed spray area. Wastewater Design Flows: This design is for a 3499 sq. ft., 4 bedroom single family residence using low flow fixtures. The projected daily wastewater flow is 3 gallons. Description of Proposed Aerobic Treatment Svstem: The residence will utilize an Aqua Safe aerobic treatment system Model A.S. 5 4 Plus 75, a proprietary treatment plant, approved by the TCEQ for use in Texas. The Model A.S. 5 4 Plus 75 is a three compartment concrete tank. The system will consist of a 4-gallon pretreatment / trashtank compartment which will gravity flow into the 5 gpd aerobic treatment compartment. The effluent from the aeration tank will gravity flow through a stack-feed chlorinator into a 75-gallon pump tank compartment. The pump tank compartment serves as a chlorine contact chamber and storage tank. Distribution is through a 1- micron mesh filter, then through Sch. 4 pvc pipe to low angle sprinkler heads. (Two-29 foot 36 radius patterns.) The system is considered a packaged system and will be installed according to the manufacturer' s instructions.

12 Construction/Installation Please see the drawings for component placement. Follow all manufacturers' instructions for the installation ofthe treatment plant and the aerator. After the tank holes are dug, a minimum of four inches of sand, sandy loam, clay loam, or pea gravel free of rock shall be placed in the holes. Tanks may then be placed in the holes, but must be left open until inspection, then back-filled with the same material that was placed under the tanks. The house sewer pipe will be 3" or 4" SDR 26 PVC (or better) tied into the stub-out from the house to the Aerobic treatment system. The pipe may be back-filled with the excavated material if allowed. The slope of the sewer pipe shall be a minimum of 1/8" fall per foot of pipe. A two-way cleanout will be placed between the house and the Aerobic plant. Fittings for the house sewer line will be the sanitary type. 4" PVC pipe will run from the trash tank compartment to the treatment plant and from the treatment tank to the pump tank compartment with a chlorine tablet stack feeder placed in-line for chlorine tablets to come into contact with the effluent for disinfection. The stack feeder is a commercially supplied Chlorinator from Aqua Safe, and is capable of maintaining a chlorine residual of 1 PPM in the pump tank for up to a four month period between refills. See diagram of the pump tank details. A pressure regulation/sampling valve (unthreaded hosebib or boiler drain) will be placed in the pump tank. The pump tank floats will be wired to a weatherproof junction box outside the tank with a wire run through buried conduit to the breaker box. Electrical power will be run from the breaker box through the alarm panel to the aerator and will run the control circuit from the alarm float in the tank to the control panel as shown on the wiring diagram on the control panel. The audio and visual alarm must be installed in a place that will be conspicuous to the owner. The pump activation controls will be run through a commercial irrigation timer to cycle power on between 12 and 5 A.M. The aerator should be mounted as close to the tank as is practical, but no greater than 5 feet away. A 1 " PVC airline will be run from the aerator connector to the airline stub out in the Plant. The aerator should be mounted in housing in a location that is dry, not dusty and is well ventilated. NOTE: All electrical wiring shall conform to the requirements of the National Electric Code (1999) or under any other standards approved by the executive director. Additionally, all external wiring shall be installed in approved, rigid, non-metallic gray code electrical conduit. The conduit shall be buried according to the requirements in the National Electrical Code and terminated at a main circuit breaker panel or sub-panel. Connections shall be in approved junction boxes. All electrical components shall have an electrical disconnect within direct vision from the place where the electrical device is being serviced. Electrical disconnects must be weatherproof (approved for outdoor use) and have maintenance lockout provisions Sch. 4 PVC will run to the sprinkler heads. The pipe should be placed 6-8 inches below the ground, unless crossing water lines. When a water supply must be crossed by a spray irrigation line, the installer will locate the spray irrigation line at least six inches below the water supply line and center a

13 / twenty foot long pipe on the water line, thus making the pipe joints at least ten feet from the water line. In situations where the irrigation line cannot be placed below the water line, the irrigation line must be placed at least six inches above the water line, then center a twenty-foot long (or longer) pipe on the water line, and sleeve the irrigation line inside another pressure rated pipe. Pipe routed under traffic bearing areas must be sleeved with Sch. 4 PVC. Landscapine: The existing vegetation at this site is suitable for surface irrigation, however all exposed rock within spray area shall be covered with at least 3 inches of soil and seeded with a mix of rye and Bermuda grasses prior to system operation. Some trees may be required to be removed to avoid obstruction of the application area. It is recommended that a good stand of vegetation be established prior to system operation. Inspection: One open pit inspection will be performed when system components are in place and operational. Hays County Environmental Health Department may require more inspections. Maintenance Requirements: Permit approval requires the applicant to furnish to the regulatory authority a valid maintenance contract with a maintenance company. The maintenance company will verify that the surface irrigation system is operating properly and that they will provide on-going maintenance of the installation. The initial maintenance contract must be valid for a minimum of two years. A maintenance contract will authorize the Maintenance Company to maintain and repair the system as needed. Again, a copy of the signed maintenance contract between the property owner and the approved Maintenance Company shall be provided to the permitting authority prior to final permit approval. The owner shall continuously maintain a signed written contract with a valid maintenance company and shall submit a copy of the contract to the permitting authority at least 3 days prior to the date service will cease. If the property owner or Maintenance Company desires to discontinue the provisions of the maintenance contract, the Maintenance Company shall notify, in writing, the permit authority at least 3 days prior to the date service will cease. If a maintenance company discontinues business, the property owner shall within 3 days of the termination date, contract with another approved maintenance company and provide the permitting authority with a copy ofthe newly signed maintenance contract. Affidavit: Prior to issuance of a permit, a certified copy of an affidavit, which has been duly recorded at the Hays County clerk's office and filed in reference to the real property deed on which the surface application system is to be installed, must be submitted. Such an affidavit shall state that the property shall not be transferred to a new owner without:

14 (1) The new owner being advised that the property contains a surface application system for wastewater disposal; (2) The permit issued to the previous owner of the property being transferred to the new owner in accordance with 285.2(5) of the TCEQ OSSF Rules, i.e.; the permit will be issued in the name of the owner ofthe 5SF. Permits shall be transferred to the new owner automatically upon legal sale ofthe OSSF. The transfer of an OSSF permit under this section shall occur upon actual transfer of the property on which the OSSF is located unless the ownership of the OSSF had been severed from the property. authority. (3) The new owners submitting a valid signed maintenance contract to the permitting Testing and reporting: The maintenance company shall inspect each permitted surface irrigation system as directed by the testing and reporting schedule shown in (4) of the TCEQ OSSF Rules, or as may be required by the Hays County Environmental Health Department. The Maintenance Company shall report any responses to homeowner complaints and the results of its maintenance findings to the Hays County Environmental Health Department within ten days ofthe specified reporting frequency. Treated effluent must be disinfected prior to surface application. The efficiency of the disinfection procedure will be established by monitoring the fecal coliform count or total chlorine residual from representative effluent grab samples as directed in the testing and reporting schedule. The frequency of testing and type of tests required are shown in (4) ofthe TCEQ OSSF Rules. OSSF Maintenance and management Practices: (1) A OSSF should not be treated as if it were a normal city sewer system. (2) The excessive use of in-sink garbage grinders and grease discarding should be avoided. In-sink garbage grinders can cause a rapid buildup of sludge or scum resulting in a requirement for more frequent cleaning and possible system failure. (3) Do not use the toilet to dispose of cleaning tissue, cigarette butts, or other trash. This disposal practice will waste water and also impose an undesired solids load on the treatment system. (4) Septic tanks shall be cleaned before sludge accumulates to a point where it approaches the bottom of the outlet device. If sludge or scum accumulates to this point, solids will leave the tank with the liquid and possibly cause clogging resulting in sewage surfacing or backing up into the house through the plumbing fixtures. (5) Since it is not practical for the average homeowner to inspect his tank and determine the need for cleaning, a regular schedule of cleaning the tank at two-to-three year intervals should be established. Commercial cleaners are equipped to readily perform the cleaning operation. Owners of OSSF's shall engage only persons registered with the TCEQ to transport the septic tank cleanings. (6) Do not build driveways, storage buildings, or other structures over the treatment works or its disposal field. (7) Chemical additives or the so-called enzymes are not necessary for the operation of a

15 septic tank. Some ofthese additives may even be harmful to the tank's operation (8) Soaps, detergents, bleaches, drain cleaners, and other household cleaning materials will very seldom affect the operation of the system. However moderation should be exercised in the use of such materials. (9) Chapter states the owner shall not allow water softener or reverse osmosis backflush to enter into any portion ofthe OSSF. (1) The liquid from the OSSF is still heavily laden with bacteria. The surfacing of this liquid constitutes a hazard to the health of those that might come into contact with it. Water Conservation Practices (1) Showers usually use less water than baths. Install a water saving shower head that uses less than two and 1 /2 gallons per minute saves both water and energy. (2) If you take a tub bath, reduce the level of the water in the tub from the level to which you customarily fill it. possible. (3) Leaky faucets and faulty toilets fill-up mechanisms should be repaired as quickly as (4) Check toilets for leaks that may not be apparent. Add a few drops of food coloring into the tank. Do not flush. If the color appears in the bowl within a few minutes, the toilet fill or ball-cock valve needs to be adjusted to prevent water from overflowing the stand pipe or the flapper at the bottom of the toilet tank need to be replaced. (5) Reduce the amount of water used for flushing the toilet by installing one of the following: a new toilet (1.6 gallons); a toilet dam; or filling and capping one quart plastic bottles with water (usually one is all that will fit in smaller toilet tanks) and lowering them into tank of the existing 3.5 gallon or larger toilet. Do not use bricks since they may crumble and cause damage to the fixture. (6) Try to run the dishwasher with a fullload, whenever possible. (7) Avoid running the water continuously for brushing teeth, washing hands, rinsing kitchen utensils or for cleaning vegetables. (8) Use faucet aerators that restrict flow to no more that 2-2 gallons per minute to reduce water consumption. turns cool. water. (9) Keep a container if drinking water in the refrigerator instead of running the faucet until it (1) Insulate hot water pipes to avoid long delays of wasted water while waiting for the heated (11) Ask your federal, state, county. City or local government about their programs to conserve water and how they can help you save water.
