§ 4.0. Water and wastewater design requirements.

Water System.

Water lines adequate for domestic supply and for fire protection needs shall be installed to serve each lot, or tract, in every subdivision where connection is to be made immediately to a community or a utility water system in accordance with the Texas Commission on Environmental Quality and town design standards and specifications. In subdivisions outside the town limits, where such connection to a system is not to be made immediately, plans shall be prepared for future installation of a water distribution system to serve each lot or tract.

A.

Water System Extensions. Water system extensions shall be designed to provide for a domestic supply of at least 100 gallons per capita per day delivered at a minimum pressure of 50 pounds per square inch. The 100-gallon rate of supply shall not be required if, in the opinion of the town's engineer, the proper point of connection to the existing system for the extension is not capable of supplying such a volume. However, the extension shall be designed to convey the 100-gallon rate should the supply point be subsequently improved. If the 50 pounds minimum pressure cannot be provided by existing system pressure or because of the elevation of the tract to be developed, a booster pump system shall be included which will provide that minimum pressure.

B.

All Supply and Distribution Mains. All supply and distribution mains installed within a subdivision must extend to the borders of the subdivision as required for future extensions of the system, regardless of whether or not such extensions are required for service within the subdivision.

C.

Fire Hydrants. Fire hydrants shall be provided at locations such that all areas of development are located within a 500-foot radius from a fire hydrant. All such fire hydrants shall be served by a six inch or larger supply or distribution main.

D.

Extension for Single Customer.

1.

When it is necessary to extend a water line to serve a new single customer where only one meter will be installed, the town at its own expense will extend the said water line up to 100 feet.

2.

If a greater distance than 100 feet is required to reach the nearest property line of the new single customer, the said single customer shall pay 100 percent of cost extension in excess of 100 feet.

3.

If more than one single customer is served by the main extension, 100 feet of main will be allowed for each single customer thus served, and any excess footage will be paid for at 100 percent.

4.

No more than one single customer credit of 100 feet will be allowed each lot or tract of record so served regardless of the number of buildings, occupied or otherwise, which might be located on said lot or tract.

5.

Payment will be made in advance of construction.

E.

Extensions to Serve Developers.

1.

The developer will pay 100 percent of the construction cost of the size mains required to serve his development, including the approach main, plus ten percent of the developer's share of the construction cost for engineering, supervision and inspection, or six percent if a private engineer approved by the utilities supervisor is employed by the developer and furnishes approved plats and specifications.

2.

When the developer desires that water mains be extended to serve his property, he will submit a request in writing to the utilities supervisor. The property to be served shall be listed showing the lot, block and subdivision. Two approved plats of the area to be served shall be attached to the request and shall become the property of the town.

3.

If the area to be served is a part of a larger area that is owned or controlled by the developer and which is reasonably expected to be served by water in the future, then two approved plats or approved preliminary plats of the larger area shall also be submitted. A tentative design of a main layout will be made of the entire area, but the cost estimate will be made on that portion of the subdivision to be served immediately.

F.

Materials and Workmanship. All materials and workmanship incorporated in water system extensions shall be in accordance with the currently adopted town construction specifications.

G.

Water Well Design Requirements. Water well must be meet current standard design practice.

Wastewater System

Sanitary sewers shall be installed to serve each lot, or tract, in every subdivision where connection is to be made immediately to a community disposal system or to a public sewerage system.

A.

Sewer Extensions.

1.

All sewer extensions shall be designed in accordance with the latest applicable rules and regulations as published by the Texas State Department of Health. No sewer lateral shall be smaller than six inch in nominal diameter. All sewers shall be designed with consideration for serving the full drainage area subject to collection by the sewer in question except as modified with the concurrence of the town's engineer because of the projected rate of development or the financial feasibility of the proposed extension.

2.

All subdivisions developed subsequent to this ordinance must be served by community sanitary sewerage collection, treatment and disposal systems approved by the town with exceptions granted only if all of the following conditions exist: (1) the subdivision in question is less than five parcels of land, (2) the existing community type collection, treatment and disposal system is not and cannot feasibly, in the opinion of the town's engineer, be made available to the area of development, and (3) percolation tests run by an independent testing laboratory are submitted to both the town and county health department with results showing that a septic tank and spreader field can be developed to provide adequate disposal of the sewage.

B.

Lateral and Sewer Mains. All lateral and sewer mains installed within a subdivision must extend to the borders of the subdivision as required for future extensions of the collecting system regardless of whether or not such extensions are required for service within the subdivision.

C.

Lift Stations or Separate Treatment Facilities. The provision for lift stations or separate treatment facilities will not be permitted unless the cost of constructing such lift stations or separate facilities is at least 20 percent less than the costs of constructing an adequate outfall or approach sewer from the existing system.

D.

Septic Tank. A septic tank with a capacity of not less than 500 gallons and with a drain field of not less than 150 feet shall be installed on each lot in accordance with the regulations of the county and state health officers.

E.

Extensions for Single Customers.

1.

Where it is necessary to extend a sewer line to serve a new "single customer," the town, at its own expense, will extend said sewer up to 100 feet.

2.

If a greater distance than 100 feet should be required to extend the line to the nearest property line of the customer, said single customer shall pay the excess over the 100 feet allowable at the rate of 100 [percent] of cost.

3.

If more than one single customer is served by the main extension, 100 lineal feet of sewer will be allowed for each single customer thus served, and any excess footage will be paid for at 100 percent of cost.

4.

No more than one single customer credit of 100 feet will be allowed for each lot or tract of record so served regardless of the number of buildings, occupied or otherwise, which might be located on said lot or tract.

5.

Payment will be made in advance of construction.

F.

Extensions to Serve Developers. The developer shall pay 100 percent of the construction cost of all sewers including "approach mains," but excepting "service lines," plus ten percent of the developer's share of the construction cost for engineering, supervision and inspection, or six percent if a private engineer approved by the utilities supervisor is employed by the developer and furnishes approved plans and specifications.

1.

The developer will also pay 100 percent of the cost of "service lines" to all lots to be served by a sewer located in the street. Said "service lines" will be constructed at the same time as a part of the same contract as all other sewers in the developer's addition. If the sewers are being constructed by town forces, the "service lines" will be constructed by town forces at the time all other sewers within the addition are constructed.

2.

The utilities supervisor shall determine the size of "approach main" required to serve developer's property and the actual size to be constructed. Should the town elect to construct a main larger than the developer's required "approach main," the developer will not be charged for the additional size.

3.

The amount of developer's payment shall be determined using unit bid prices contained in the award contract.

G.

Connections. No connection shall be made to any sanitary sewerage system within the town which will permit the entrance of surface water or waste of other than domestic sewage characteristics without the specific authorization by the town council.

H.

Materials and Workmanship. All materials and workmanship incorporated in the sewage system extensions shall be in accordance with the currently adopted town construction specifications.
