1.0 Introduction MTE Consultants Inc. has been retained by GSP Group Inc. to conduct a fire flow analysis for the proposed six-storey residential building at 191 Suncoast Drive East located in the Town of Goderich. Proposed servicing works include the installation of sanitary, storm and water services for the proposed building. It’s our understanding that the building will be sprinklered. There is an existing municipal hydrant located on the north side of Suncoast Drive East, approximately 35m away from the proposed building’s Fire Department Connection (FDC). The purpose of this report is to confirm the available fire flows and residual pressure from the existing 200mm diameter watermain along Suncoast Drive East.

2.0 Water Distribution The development will be serviced from an existing 200mm diameter watermain located within the Suncoast Drive East right-of-way. The proposed 150mm diameter water service will be extended into the Site and will service the proposed building. Based on the distance from the existing hydrant located on Suncoast Drive East and the proposed fire department connection, a private hydrant on-site should not be required. The pressures and flows must be sufficient for firefighting conditions as established by the Ontario Building Code (2012). The minimum residual pressure under fire fighting conditions is 140kPa (20.3 psi) per OBC 2012 A-3.2.5.7 3(b). For this design, we have utilized the information obtained from the municipal hydrants located on Suncoast Drive East. The following table illustrates the results of the testing completed by B.M. Ross and Associates Limited.

3.0 Analysis of On-Site Fire Protection Section A-3.2.5.7.2 of the OBC relates to water supply for firefighting in sprinklered buildings. For sprinklered buildings, water supply additional to that required by the sprinkler systems should be provided for firefighting using fire hoses in accordance with the hose stream demands and water supply durations for different hazard classifications as specified in National Fire Protection Association’s (NFPA) NFPA 13, “Standard for the Installation of Sprinkler Systems”. The site-specific system demand for the proposed sprinkler system is not known at this time. Based on past experience, an assumed demand of 2,000L/min has been used to represent the fire demand for the proposed building. The actual sprinkler demand will be provided by a qualified contractor and this calculation will need to be confirmed. The residual pressure at the existing hydrant was calculated to be 395kPa for a flow rate of 2,000L/min, which is greater than the minimum allowable pressure of 140kPa per OBC 2012. See Appendix B for calculations. However, in case the fire demand for the proposed building was found to be over 2,000L/min, a demand of 9,000L/min was also used to determine the residual pressure at the existing municipal hydrant. The residual pressure at the existing municipal hydrant was calculated to be 323kPa for a flow rate of 9,000 L/min, which is greater than the minimum allowable pressure of 140kPa per OBC 2012. See Appendix B for calculations. Following the hydrant flow testing, B.M. Ross and Associates noted that the flow test results may overestimate the maximum flow available from the hydrant at 140kPa, on account of the relatively large 200mm diameter of the watermain along Suncoast Avenue East. Nevertheless, B.M. Ross and Associates estimates that the hydrant can provide in excess of 13,500 L/min at 140kPa, which is a much larger demand than what will be required for firefighting purposes, as previously discussed.

4.0 Conclusions and Recommendations Based on the flow test provided by B.M. Ross and Associates Limited, it can be concluded that the minimum water supply flow rate of 9,000L/min can be delivered to the existing municipal hydrant located south of the proposed building with a residual pressure (at the nozzle of the hydrant) under fire fighting conditions of 323kPa, thus meeting the minimum requirements of the Ontario Building Code (2012). We understand that the building will be sprinklered, therefore, the fire demands will be far less than 9,000L/min. Given that there is adequate supply and pressure for a demand of 9,000L/min, we conclude that the existing municipal hydrant can adequately service the proposed residential building. All of which is respectfully submitted,

Dear Sir

RE: Hydrant Flow Test on Suncoast Drive

Background

MTE is completing a Functional Servicing Report for 191 Suncoast Drive in Goderich and requested that BMROSS complete a hydrant flow test adjacent to the property to provide flow and pressure data. BMROSS completed the testing with support from Veolia, the operator for the Town of Goderich. The purpose of this letter is to report the findings of the hydrant flow test.

Technical Analysis – Hydrant Flow Tests

On April 30, 2021, staff of BMROSS and Veolia conducted a hydrant flow test on Suncoast Drive. Figure 1 (enclosed) illustrates the general location of the hydrants used for the test. A full copy of the hydrant test results is also enclosed. The hydrant of primary interest is labelled EAST on Figure 1. Table 1 provides the measured pressures and theoretical flow rates available at each test location.

It is noted that even with two ports fully open on the flowing hydrant, it was not possible to induce a pressure drop of 25% at the test hydrant. This is likely a result of relatively large diameter watermain feeding the 200 mm diameter watermain on Suncoast Drive from both west and east directions. Though the theoretical calculations suggest an available fire flow of 289 L/s at a residual pressure of 140 kPa, this is a relatively extreme flow value. We suggest it may be more appropriate to consider the hydrant could provide >225 L/s at 140 kPa.

Conclusions

A hydrant flow test was conducted in the vicinity of the 191 Suncoast Drive property in Goderich. On April 30, 2021, test results indicate the existing municipal water distribution system in Goderich would be able to provide a flow of >225 L/s at a residual pressure of 140 kPa.

If you have any questions, or require additional information, please call.

Yours very truly
