When a consumer receiving service at the water system main or service connection must by means of a pump of any kind elevate or increase the pressure of the water received, the pump shall not be attached to any pipe directly connected to the main or service pipe. Such pumping or boosting of pressure shall be done from a sump, cistern, or storage tank which may be served by but not directly connected with the water system distribution facilities.

Exception: With prior approval of the city engineer and the fire marshal, a booster pump may be connected to the private property side of the city meter and/or backflow preventer if such pump is designed with control systems and/or engineered calculations showing it will not allow the pump to reduce the city pressure below twenty pounds per square inch. In low pressure areas said installation(s) shall be evaluated for cumulative impacts to the city water main pressures and approved by the city.
