~~ .~ -.. drain field and individual on-site septic tank, pump tank systems. The utility that will be brought on board will be licensed by the State of North Carolina's Utilities '~"~~ Commission. The Utility operator will not own the facil-ities because owning the `i facility might be a disadvantage because of the unit's size. It is difficult to sell a ~! 15 lot subdivision with a maximum utility rating price of $18.00 per month to a utility. They do not want to bother with the little subdivision. Therefore, they altered the proposal so that the Homeowners Association would own the drain field and would lease, in perpetuity with a strong no termination clause, to the Utility. The only way the Utility Operator can be terminated is by negligence, failure or abandonment of the project. If this happened, he would have already posted a $10,000 bond, which would be revoked at that time. A second operator would be brought on to maintain the system. He indicated that they also believe that it is to the benefit of all subdivision lot owners to own their own septic tank and systems. However, they intend to build all l5 units with a Utility Operator overseeing and supplying the equipment. They will not be built by independent manufacturers supplying whatever is available at the time. They will be built under a strong specification. Each lot will place a certain amount of money in an escrow account. This account will be overseen by the Homeowners Association and the Utility Operator. In the event of system or equipment failure, the money in the account will be used for repair. The access to the account will be by double signature by the President of the Homeowners Association and the President of the Utility. He indicated that they are trying to build in safeguards for residential habitation of this area and to allow the development of land without the total restriction and abandonment of this project. He asked if no development is going to occur in the watershed, who is going to own it and maintain it? GOMMISSIONER HALKIOTTS asked why the central pumping tank would be built of concrete block? MIL. MORGAN stated that he had built 25 to 30 concrete pumping facilities in Dare ;::a County, Kill Devil Hills, and Nags Head. He indicated that 95~ of them are 70~ below the water table. He indicated that a full tank in a water table is not going to infiltrate and exfiltrate. It is hydrostatically balanced. The only time there is an imbalance is when the water table drops below the level of the tank or the tank is empty. Concrete block is not impervious to moisture penetration but compound is.put on the blocks to help reduce any moisture and to further waterproof these tanks. He assured the Commissioners that there would be no interchange between the tanks and the groundwater table on the outside, unless there is an imbalance. That could be caused by the tank above the ground being full or the tank empty and below the water table. At that point he would be most concerned about floating. He stated that precast concrete tanks have a reputation for leaking which is why they do not use them. Commissioner Halkiotis stated that a concrete block structure that was built for a school in this county because of the imbalance came to the surface. MR. MORGAN indicated that the concrete block tank will be set on a minimum slab of 12" reinforced. The tank has reinforcing rods, and it is poured and filled with 2500 pound concrete. Mr. Morgan stated that the structural integrity of a concrete block will withstand the stress of water, earth pressures, cracking or overburdened to do the job intended. MR. BEST questioned whether the difference in the soils at the beach and in Orange County would have a great impact on the construction and operation of a system.
