[Adopted 6-19-1978 by Ord. No. 78-06]
A. 
This article shall be known as the "East Brandywine Township Water Supply and Distribution Ordinance of 1978."
B. 
Unless otherwise specified, the following words shall have the following meanings when used in this article:
PERSON
Includes, in addition to a natural person, a corporation, partnership, association or other legal entity and its officers, employees and agents.
A. 
Any person installing, maintaining, repairing or replacing a domestic water system or facilities, or portion thereof, within East Brandywine Township shall comply with the appropriate rules and regulations of the Pennsylvania Department of Environmental Protection (PDEP) contained in the current edition of the Public Water Supply Manual, Bureau of Water Quality Management, Publication No. 15.
B. 
The regulations set forth in this article are intended to supplement the requirements of the above-mentioned PDEP rules and regulations. Some sections contained in this article will duplicate PDEP regulations. Where pertinent regulations in this article are in variance with PDEP requirements, the more stringent requirements or regulations shall govern.
A. 
Water supply for domestic use only shall be considered in this article. Water demand and facilities that are necessary for fire-fighting use are not included in this article.
B. 
Basis of water demand and storage.
(1) 
Average daily flow shall be calculated on 100 gallons per day per person, using 3.5 persons per dwelling unit, resulting in 350 gallons per day per dwelling unit. A "dwelling unit" is defined as a single house, apartment unit or a condominium. This amount includes water used for lawn sprinkling and an accepted allowance for unaccounted water.
(2) 
The maximum daily flow shall be 2.5 times the average daily flow in gallons.
(3) 
For practical purposes, it is considered that all water for domestic requirements is used in a sixteen-hour period each day. The following procedure shall be used to determine the average hourly rate and the pumping requirements in gallons per minute:
Average hourly rate (gallons/hour) = Average daily flow (gallons)/16 hours
Maximum hourly demand (gallons) = Average hourly rate (gallons/hour) multiplied by a peak factor of 3.0
Rated well-pumping capacity (gallons/minute) = Maximum hourly demand/60
(4) 
Storage requirements.
(a) 
System storage shall be provided in the initial phase of construction that shall be adequate in capacity to serve all the ultimate construction within the total boundary of the subdivision or district.
(b) 
The minimum accepted finished water effective storage for domestic use only shall be not less than 200 gallons per equivalent dwelling unit. Where wells provide the source of supply in systems serving 50 or more equivalent dwelling units, multiple sources of supply, i.e., two wells, shall be required. In systems with less than 50 dwelling units, an auxiliary or duplicate pumping unit shall be stored for emergency use, together with an emergency power source, or, as an alternate, two days of storage shall be required based on the average daily demand in gallons.
(c) 
Where hydropneumatic tank facilities are used for storage, the capacity of the tank shall be a minimum of 30 times the rated capacity of the serving pump and, in any case, shall be able to deliver the demand capacity stated in Subsection B.
(5) 
The system facilities shall be designed and sized to provide a minimum pressure of 30 psi during maximum flow in all mains within the boundary of the division or district. Pressure regulators shall be installed as required at locations to restrict the pressure in the mains to no more than 100 psi at minimum flow conditions.
A. 
The requirements and procedures necessary for developing and constructing production well facilities for domestic water use shall be in accordance with PDEP regulations and other regulatory agencies having jurisdiction.
B. 
Each well shall be tested by an approved method for yield, drawdown, and duration requirements.
C. 
For general considerations, the tested yield shall be 25% above the production requirements of the well sustained for a minimum of 48 hours.
D. 
The water quality of each developed well source shall be able to meet the requirements of the Interim Primary Regulations of the Safe Drinking Water Act[1] (Public Law 93-523) (SDWA), established by the Environmental Protection Agency (EPA), with PDEP having the responsibility of enforcement of the law.
[1]
Editor's Note: See 35 P.S. § 721.1 et seq.
E. 
The type of treatment necessary for the finished water to meet the requirements of the SDWA must be provided with the required sampling analyses, monitoring, record and report keeping and other procedures complying with the law and necessary for the certification of the quality of the finished water furnished to the consumers.
F. 
Disinfectant shall be considered a minimum treatment requirement that must have a minimum of 20 minutes detention time from the point of application to the first consumer based on the maximum hourly flow rate.
G. 
Wells shall not be located in floodplains.
A. 
The distribution system for a residential district or subdivision shall be laid out in a grid pattern and looped where possible and also to avoid the use of dead ends.
B. 
Mains included in the grid pattern shall be a minimum of six inches in diameter and so arranged that, on the long side of blocks, the lengths of mains between intersecting mains are no more than 600 feet. The use of eight-inch pipe shall be used for distances greater than 600 feet.
C. 
Mains located on principal streets and arterial mains shall be eight inches minimum in size. In the event dead ends cannot be avoided, blowoffs must be installed at the dead ends to permit flushing of the main.
D. 
The following table shows the maximum number of customers allowed on small mains based on dead-end pipelines:
