Specifications include, but are not limited to: Construct an onsite sewage system that meets the location and construction specifications of the Virginia Sewage Handling and Disposal Regulations (12VAC5-610-10 et seq., the Regulations) and the Regulations for Alternative Onsite Sewage Systems (12VAC5-613-10 et seq.). B) Construct the above Alternative onsite sewage disposal system in compliance with the Henrico County Health Department Construction Permit 2023-143-0013 at 381 North Mullens Road, Highland Springs, VA 23075 in the location shown on the permit. The permit may contain additional conditions, notes, and information needed to construct the onsite sewage system. C) Sewer and conveyance line shall be replaced, and these costs shall be reflected in bid. Existing drainfield laterals are to be disconnected and cost of newly proposed drainfield laterals shall be reflected in bid. D) Septic Pump-out Requirements: All bids shall include the cost to pump out the contents of the existing septic tank by a properly licensed sewage hauler. To prevent sewage from backing into the home or erupting on property surface prior to the completion of the septic work, additional pump outs of the contents of the existing septic tank by a properly licensed sewage hauler may be required on an as-needed basis. Bids should provide a cost-breakdown per additional pump out. If multiple pump outs are needed preauthorization will need to occur to allow for a change order for additional, justifiable pump outs. If the permit requires work within or under the existing drainfield (as indicated in the Permit) additional monitoring and pumping of the existing septic tank may be required in order to allow for the drying out of the drainfield and additional pumpouts may be needed. In these cases, for two weeks prior to the installation or repair of the onsite sewage system the septic tank would need to pumped out every 4 days for 2 weeks. Costs per additional pumpout shall be provided. The contents of the existing septic tank shall be pumped by a properly licensed sewage hauler to prevent sewage from entering the drainfield for at least 2 weeks prior to installation.
