Looks like I'm going to get a standard sewage pump/basin system for one of my customers and try to bury it somehow in spite of the steep slope and rock. Does this model seem to be of quality and of reasonable price? Is there a better place for me to look? It's for a customer's vacation cabin and little guest house sharing a main drain. Thanks! http://www.sumppumpsdirect.com/Little-Giant-511663-Sewage-Pump/p70705.html
