BMP element. Potential problems: How to remediate the problem: The entire system A component of the system is damaged or leaking. Make any necessary repairs or replace if damage is too large for repair. Water is flowing out of the overflow pipe during a design rainfall or smaller (usually a 1”). Check system for clogging and damage. Repair as needed so the design volume is stored properly without discharging during a design storm. Check that the pump is operating properly and that the water is actually being used at the volume designed. If it is still not operating properly, then consult an expert. The captured roof area Excess debris or sediment is present on the rooftop. Remove the debris or sediment as soon as possible. The gutter system Gutters are clogged, or water is backing up out of the gutter system. Unclog and remove debris. May need to install gutter screens to prevent future clogging. Rooftop runoff not making it into gutter system. Correct the positioning or installation of gutters. Replace if necessary to capture the roof runoff. BMP element: Potential problems: How to remediate the problem: The pump Pump is not operating properly. Check to see if the system is clogged and flush if necessary. If it is still not operating, then consult an expert. The overflow pipe Erosion is evident at the overflow discharge point. Stabilize immediately. The overflow pipe is clogged. Unclog or replace if it cannot be unclogged. The outflow pipe is damaged. Repair or replace the pipe. The secondary water supply Not operating properly. Consult an expert. The cistern Sediment accumulation of 5% or more of the design volume. Remove sediment. Algae growth is present inside the cistern. Do not allow sunlight to penetrate the cistern.

Witness my hand and official seal, SEAL My commission expires Rainwater Harvesting System Operation and Maintenance Agreement I will keep a maintenance record on this BMP. This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important maintenance procedures: − The roof area will be maintained to reduce the debris and sediment load to the system. Excess debris can clog the system and lead to bypass of the design storm, and reduced reuse volume....
BMP element. Potential problem: How to remediate the problem: The surface of the permeable pavement Rutting / uneven settlement This indicates inadequate compaction of the pavement base / sub-base. If rutting or uneven settlement on the order of ½ inch or greater occurs, permeable pavement shall be removed and base / sub-base re-compacted, smoothed, and permeable pavement shall then be re- installed. Base and sub-base compaction shall be monitored by a licensed geotechnical engineer to ensure that infiltration capacity of base and sub-base are not compromised by compaction and smoothing processes. The pavement does not xxxxxxx between storms, or water is running off. Vacuum sweep the pavement. If the pavement still does not xxxxxxx, consult a professional. The permeable pavement will be inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches. Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.
