(A) The developer or its' engineer(s), prior to any request for permitting of such, shall meet with town engineers in technical advisory committee session(s) to discuss plans for the design and installation of any sewage collection system and any associated lift station whose effluent is intended to be processed at the town sewage plant. The approval of the Town Sanitary Board shall be required for the design of electrical and mechanical components prior to the developer filing for and receiving town permits, the issuance of which would constitute permission for the installation of a sewage collection facility including any necessary lift station(s). Town permission for installation does not obviate the need for permitting from other agencies.
(B) It is the intent of this standard that the developer, the developer's engineer, town officials and staff and the Town Engineer would develop a collection system, lift station and force main design to deliver an exceptionally reliable system configured with mechanical and electrical equipment capable of delivering the lowest practicable operation and maintenance cost.
(C) At a minimum the collection system design shall include:
(1) Design consistent with the requirement of 327 I.A.C. Article 3.
(2) Acceptance testing after construction with Town Engineer observation, including mandrel testing, manhole vacuum testing in accordance with ASTM C-1244 and sewer air pressure testing. Detailed testing protocols will be provided.
(3) Manhole castings shall include closed pickhole gasketed covers. External chimney seals shall be provided.
(D) At a minimum the lift station design shall be a design consistent with the requirement of 327 I.A.C. Article 3.
(E) Acceptable site and access requirements:
(1) This facility shall be located in such a manner that it is accessible by means of a 15 foot wide concrete paved drive which conforms to the town's standards and connects to a public street right-of-way. The facility shall be placed on a parcel of land, dedicated to the town, having sufficient area for the facility but in no case have less than 1,200 square feet (a parcel size of no less than 30' x 40'). A site plan of the lift station parcel and its improvements shall be submitted to and approved by the town.
(2) A fiberglass enclosure. Fiberglass enclosure shall be of the hinged tip-up design. The enclosure shall be large enough to accommodate inside storage of all specified equipment, including generator, transfer switch, and convenience accessories.
(3) Landscaped to be unobtrusive. The necessity of a fence to be determined by Town Engineer.
(4) Redundant submersible pumps - each able to carry the initial and eventual load of the area to be served. Each pump shall be designed as a completely submersible wastewater pump capable of pumping raw unscreened domestic sewage consisting of water, fibrous material, heavy sludge, and spherical solids at least three inches in diameter.
(5) Pumps to be installed and operated on a rail guide system which allows pumps to be removed without entering the wet well; design must be approved by Town Engineer.
(6) Stand by generator/system monitoring incoming power and capable of the automatic transfer to generator power including the starting and running of each pump. The engine shall be stationary, liquid cooled, spark ignited for natural gas fuel.
(7) Concrete wet well. The wet well shall be constructed of pre-cast, reinforced concrete sections. The wet well volume shall be based on design average flow and a filling time to exceed 30 minutes.
(8) Telemetry and alarm system. The manufacturer shall provide a continuous 24 hour alarm monitoring system to monitor the status of the pumps and generator. The system shall relay information to a web site, where it can be exclusively accessed by the user. The system shall also have the capability of instantaneous alarm notification through telephone calling, e-mails, pages, or any combination of those items.
(9) Station piping and bypass. The station valving and piping shall be housed within the fiberglass structure. The pump station shall include a pump bypass system. The purpose of this system is to facilitate the connection of an emergency pump to a fixed suction and fixed by-pass force-main connection at the lift station.
(10) Approved specifications, vendor and equipment list to be provided by town; equipment components must be approved by town engineers.
(11) Rigorous acceptance testing of all lift station systems with Town Engineer observation.
